Abstract
BACKGROUND HIV-associated neurocognitive disorder (HAND) negatively impacts quality of life (QoL) of people living with HIV who are on antiretroviral therapy (ART). Behavioural intervention adjunct to ART may improve QoL of people with HAND. We determine the effect of a 12-week aerobic exercise programme on QoL in people with HAND who were receiving ART. TRIAL DESIGN This was a parallel-group, randomised controlled trial with concealed allocation and intention-to-treat analysis. METHODS We identified 73 participants diagnosed with HAND. Participants were sampled from an earlier study that examined the prevalence of HAND according to the Frascati criteria. Participants were randomised and allocated to an intervention of 12-weeks of aerobic exercise, comprising three 20-60 min sessions per week of moderate-intensity aerobic exercise using a cycle ergometer. The primary outcome was QoL, which was evaluated using the World Health Quality of Life Questionnaire (WHOQoL)-BREF. RESULTS Participants in the exercise (n = 39) and control (n = 35) groups had similar sociodemographic characteristics (p > 0.05). Following the 12-week aerobic exercise programme, participants in the exercise group had improved physical (p < 0.001), psychological (p = 0.008) and environmental (p = 0.001) domains of the QoL (p = 0.001) and overall QoL (p = 0.001) relative to the control group. Similarly, participants in the exercise group had lower depression scores than participants in the control group. Depression scores in the exercise group were still lower 3 months post-intervention (p = 0.007). Only the improvements in physical (p = 0.02) and psychological (p = 0.007) domains of QoL were sustained at 3 months post-intervention. CONCLUSIONS Aerobic exercise improves the QoL of people with HAND. To ensure sustained benefits, people with HAND may need to engage in long-term physical exercise. Trial registration The trial is registered with the PAN African Trial Registry (PACTR). Date: 01/09/2020, ID: PACTR202009483415745.

Abstract
OBJECTIVE Exercise is a recommended component of care for people living with HIV/AIDS; however, it is unclear which type of exercise is most effective. The purpose of this study was to investigate the relative effects of different types of exercise interventions on aerobic capacity measured by peak oxygen consumption (peak VO2) and health-related quality of life (HRQoL) in this population. METHODS For this systematic review and indirect-comparisons meta-analysis (network meta-analysis), different electronic databases were searched up to February 2020 for randomized controlled trials that evaluated the effects of different types of exercise interventions on peak VO2 and HRQoL of people living with HIV/AIDS. Mean differences, standardized mean difference (SMD), and 95% CI were calculated. Fixed- and random-effects Bayesian network meta-analysis were used to compare the relative effectiveness of the different exercise interventions. RESULTS Forty studies met the study criteria, reporting on a total of 1518 patients. When comparing the exercise interventions with usual care (control group) for the peak VO2 outcome, combined aerobic and resistance exercise was the highest ranked exercise intervention with an SMD of 4.2 (95% CI = 2.5 to 5.9), followed by aerobic exercise (SMD = 3.1; 95% CI = 1.4 to 5.1). Compared with aerobic exercise, resistance training, and yoga, combined aerobic and resistance exercise was the best exercise intervention to promote improvement on physical function, general health, mental health, and energy/vitality domains HRQoL. CONCLUSION The combined aerobic and resistance exercise was the highest ranked exercise intervention to improve peak VO2 and HRQoL. Combined aerobic and resistance exercise should be considered as a component of care for people living with HIV/AIDS.

Abstract
People living with HIV (PLWH) have limited exercise capacity because of anemia, neuromuscular disorders, and pulmonary limitations. We used a meta-analysis to examine the effect of aerobic and resistance exercise alone and in combination on cardiovascular parameters. Subgroup meta-analyses were conducted and long-term effects of exercise were investigated. A systematic literature search was conducted up to July/August 2017. The Physiotherapy Evidence Database-scale was used to rate quality and assess the risk of bias on the papers. Standardized mean differences (SMDs) were calculated to assess the effect of exercise. Posttreatment comparison between the exercise and control groups revealed moderate and large effect sizes in favor of the intervention group for VO2max (SMD = 0.66, p < .0001) and the 6-minute walk test (SMD = 1.11, p = .0001). Exercise had a positive effect on cardiovascular parameters in PLWH. Exercise can be a prevention factor for PLWH dealing with multiple comorbidities.

Abstract
Pharmacologic advancements in the treatment of human immunodeficiency virus (HIV) has extended the life expectancy of people living with HIV (PLWH). An unfortunate side effect of HIV treatment, however, is an increased prevalence of dyslipidemia, glycemic dysregulation and abnormal distribution of body fat (lipodystrophy). Consequently, the risk of developing cardiovascular disease (CVD) is significantly increased in PLWH and ultimately a major cause of mortality. Physical activity and exercise training are interventions that have effectively protected against the development of CVD and, in the presence of CVD, has help mitigate morbidity and mortality. Early concerns over potential immunosuppressive effects of exercise in PLWH have largely been dispelled and in some cases exercise has been shown to strengthen markers of immune function. Interventions with aerobic exercise, resistance exercise, and their combination, particularly at higher intensities, are showing promising health outcomes in PLWH. This review will summarize the key cardiovascular and metabolic effects of antiretroviral therapy; the effects of the types and intensities of exercise on cardiorespiratory fitness, cardiometabolic markers, and muscle strength; and provide recommendations on strategies to apply exercise interventions in clinical settings.

Abstract
INTRODUCTION To our knowledge, there are no systematic review study with meta-analysis that investigated the influence of training variables on specific outcomes (CD4 cell counts) addressed aerobic training (AT) for HIV+ patients. In this sense, the purpose of this study was to perform a systematic review with meta-analysis of randomized controlled trials on AT in HIV+ patients and to analyze the influence of AT modulating variables on the CD4 cells, VO2max, and metabolic parameters. EVIDENCE ACQUISITION Searches were performed in the databases PubMed, ISI Web of Knowledge, SportDiscus, Lilacs, Science Direct, and Scielo. EVIDENCE SYNTHESIS Twelve studies involving 438 subjects (78.2% male) were included. Overall, the sample was sedentary (pre-training VO2max of 30.5 mL.kg-1.min-1) with a mean time of virus infection of 66.9 months and mean number of CD4 cells of 467.8 cells/mm3. AT increased the VO2max (ES=1050 [0.455 to 1.64]; P<0.001) and CD4 cell count (ES=0.402 [0.203 to 0.601]; P<0.001). AT for 8-12 weeks appears to be sufficient to increase VO2max, and the highest gains are associated with patients who present higher initial CD4 cell values. There was no difference to metabolic parameters. CONCLUSIONS AT did not change the metabolic parameters, but it was AT is able to promote a greater magnitude of improvement in VO2max in the initial weeks of training and a greater increase in the number of CD4 cells in patients who present a better immune condition prior to training.

Abstract
OBJECTIVE The purpose of this systematic review and meta-analysis was to examine the effects of exercise on depression and anxiety in people living with HIV (PLWH), and to evaluate, through subgroup analysis, the effects of exercise type, frequency, supervision by exercise professionals, study quality, and control group conditions on these outcomes. METHOD A literature search was conducted through four electronic databases from inception to February 2019. Considered for inclusion were randomized controlled trials (RCTs) investigating exercise interventions and depression or anxiety as outcomes in people living with HIV (≥ 18 years of age). Ten studies were included (n = 479 participants, 49.67% females at baseline), and the standardized mean difference (SMD) and heterogeneity were calculated using random-effect models. An additional pre-post meta-analysis was also conducted. RESULTS A large effect in favor of exercise when compared to controls was found for depression (SMD = -0.84, 95%CI = [-1.57, -0.11], p = 0.02) and anxiety (SMD = -1.23, 95%CI = [-2.42, -0.04], p = 0.04). Subgroup analyses for depression revealed large effects on depression for aerobic exercise only (SMD = -0.96, 95%CI = [-1.63, -0.30], p = 0.004), a frequency of ≥3 exercise sessions per week (SMD = -1.39, 95%CI = [-2.24, -0.54], p < 0.001), professionally supervised exercise (SMD = -1.40, 95%CI = [-2.46, -0.17], p = 0.03]), and high-quality studies (SMD = -1.31, 95%CI = [-2.46, -0.17], p = 0.02). CONCLUSION Exercise seems to decrease depressive symptoms and anxiety in PLWH, but other larger and high-quality studies are needed to verify these effects.

Effects of physical exercises on inflammatory biomarkers and cardiopulmonary function in patients living with HIV: a systematic review with meta-analysis. BMC Infect Dis 2019; 19:359. [PMID: 31035959 PMCID: PMC6489236 DOI: 10.1186/s12879-019-3960-0] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2018] [Accepted: 04/08/2019] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Pro-inflammatory cytokines expressed in human immune deficiency virus (HIV) infection, may induce oxidative stress likely to compromise the patency of the airways or damage the lung tissues/cardiac function. However, physical (aerobic and/or resistance) exercise-induced release of heat shock protein, immune function alteration or reduced tissue hypoxia, have been highlighted as possible mechanisms by which increasing physical activity may reduce plasma pro-inflammatory cytokines in uninfected individuals and should be appraised in the literature for evidence of similar benefits in people living with HIV (PLWH). Therefore, we evaluated the effects of physical exercises on 1) inflammatory biomarkers and 2) cardiopulmonary function (VO2 Max) in PLWH. METHOD A systematic review was conducted using the Cochrane Collaboration protocol. Searching databases, up to January 2018. Only randomized control trials investigating the effects of either aerobic or resistance or a combination of both exercise types with a control/other intervention(s) for a period of at least 4 weeks among adults living with HIV, were included. Two independent reviewers determined the eligibility of the studies. Data were extracted and risk of bias (ROB) was assessed with the Cochrane Collaboration ROB tool. Meta-analyses were conducted with random effect models using the Review Manager (RevMan) computer software. RESULT Twenty-three studies met inclusion criteria (n = 1073 participants at study completion) comprising male and female with age range 18-65 years. Three meta-analyses across three sub-groups comparisons were performed. The result showed no significant change in biomarkers of inflammation (IL-6 and IL-1β) unlike a significant (Z = 3.80, p < 0.0001) improvement in VO2 Max. Overall, the GRADE evidence for this review was of moderate quality. CONCLUSION There was evidence that engaging in either aerobic or resistance exercise, or a combination of both exercises, two to five times per week can lead to a significant improvement in cardiopulmonary function but not biomarkers of inflammation (IL-6 and IL-1β). However, this should not be interpreted as "No evidence of effect" because the individual trial studies did not attain sufficient power to detect treatment effects. The moderate grade evidence for this review suggests that further research may likely have an important impact on our confidence in the estimate of effects and may change the estimate.

Abstract
BACKGROUND Compromised immune function, associated with human immune deficiency virus(HIV) infection, is improved by antiretroviral therapy(ART) which also decreases bone mineral density(BMD), and possibly the quality of life(QoL). However, physical(aerobic/resistance) exercises, were reported to induce reverse effects in uninfected individuals and were appraised in the literature for evidence of similar benefits in people living with HIV/AIDS(PLWHA). The main study objective was to evaluate the impact of physical (aerobic and resistance) exercises on CD4+ count, BMD and QoL in PLWHA. METHODS A systematic review was conducted using the Cochrane Collaboration protocol. Searching databases, up to June 2017, only randomized control trials investigating the effects of either aerobic, resistance or a combination of both exercise types with a control/other intervention(s) for a period of at least 4 weeks among adults living with HIV, were included. Two independent reviewers determined the eligibility of the studies. Data were extracted and risk of bias(ROB) was assessed with the Cochrane Collaboration ROB tool. Meta-analyses were conducted using random effect models using the Review Manager(RevMan) computer software. RESULTS Nineteen studies met inclusion criteria(n = 491 participants at study completion) comprising male and female with age range 22-66 years. Two meta-analyses across 13 sub-group comparisons were performed. However, there were no RCTs on the impact of physical exercises on BMD in PLWHA. The result showed no significant change in CD4+ count unlike a significant effect of 5.04 point(95%CI:-8.49,-3.74,p = 0.00001) for role activity limitation due to physical health(QoL sub-domain). Overall, the GRADE evidence for this review was of moderate quality. CONCLUSIONS There was evidence that engaging in moderate intensity aerobic exercises (55-85% Maximum heart rate-MHR), for 30-60 min, two to five times/week for 6-24 weeks significantly improves role activity limitation due to physical health problems, otherwise physical(aerobic or/and resistance) exercises have no significant effects on CD4+ count and other domains of QoL. Also, there is lack of evidence on the impact of exercises on BMD in PLWHA due to the paucity of RCTs. The moderate grade evidence for this review suggests that further research may likely have an important impact on our confidence in the estimate of effects and may change the estimate.

Abstract
Evidence would suggest that regardless of disease status, people living with human immunodeficiency virus (HIV)/AIDS can obtain similar health benefits from routine physical activity reported within general populations. Research has shown significant improvements among psychological and physiologic variables within the first 5 to 6 weeks of beginning a routine physical activity program. Daily activity has shown promising results in other clinical populations, but there is still a paucity of research that limits evidence among the HIV population. Additional research is needed to examine the long-term benefits of physical activity, and to discover more practical ways to achieve this lifestyle change.

Abstract
OBJECTIVE Whether older people living with HIV (PLWH) can achieve similar functional benefits with exercise as their uninfected peers and the ideal intensity of exercise needed for these benefits are not known. DESIGN Sedentary adults (50-75 years) with or without HIV were recruited for 24 weeks of supervised endurance/resistance exercise. After 12 weeks of moderate-intensity exercise, participants were randomized to continue moderate-intensity or advance to high-intensity exercise for an additional 12 weeks. METHODS Outcomes by serostatus and exercise intensity (moderate, high) were compared using linear and mixed effects regression models and controlled for baseline values or week 12 values. RESULTS A total of 32 PLWH and 37 controls were enrolled; 27 PLWH (12 moderate/15 high) and 29 controls (15 moderate/14 high) completed 24 weeks. PLWH had significantly poorer physical function across nearly all baseline measures. Both groups had significant improvements in all functional measures. From 0 to 12 weeks, PLWH had significantly greater percentage improvements (mean, 95% confidence interval) than controls on VO2 max [5 (0, 10)%]; from 13 to 24 weeks, PLWH had significantly greater percentage improvements on stair climb [-5 (-10, -1)%], and the time to complete a 400-m walk [-3 (-5, -0)%]; all P less than 0.05. An interaction between exercise intensity and HIV serostatus was significant for measures of strength: PLWH randomized to high-intensity gained significantly more strength than moderate-intensity in bench and leg press [6 (0, 12)% and 10 (2, 17)% greater; both P < 0.05]; controls had similar gains regardless of intensity. CONCLUSION Both moderate-intensity and high-intensity exercise resulted in significant improvements in physical function; high-intensity exercise may impart greater strength benefits to PLWH.

Abstract
Objective Mental illness is highly prevalent among people living with HIV. Poor mental health is linked to HIV disease progression, making the treatment of mental illness alongside HIV essential. While the benefits of exercise on the physical health of people living with HIV are well established, the effect of exercise on mental health in this population is less examined. Therefore, this study aimed to conduct a systematic literature review of the effects of exercise on mental health in people living with HIV. Methods A search of electronic databases (PubMed, Web of Science, PsycINFO) through 30 November 2016 was completed. The methodological framework for scoping studies was used to conduct the review process. RISMA guidelines were used to report the results. Results The search resulted in 2273 articles and 52 were determined to be relevant. After review of the full text of potentially relevant studies, 24 studies were included for the analysis. Discussion Both aerobic and resistance exercise have independent and combined positive effects on various indicators of mental health in people living with HIV. Major limitations include high attrition rate, small sample size, and poor study designs. Higher quality studies with more diverse populations such as women, older adults, and transgender individuals are required.

Abstract
Physical exercise (PE) has not been well studied in persons living with HIV (PLHIV). We conducted an overview of systematic reviews to assess the effectiveness of PE and to determine the most appropriate PE regimen for PLHIV. We used the CDC's Prevention Research Synthesis Project's database and manual searches to identify systematic reviews published between 1996 and 2013. We qualitatively synthesized the findings from five reviews to assess the effectiveness of PE and conducted meta-analyses on CD4 counts to identify the best PE regimen. PE is associated with reduced adiposity and depression, but was not associated with a decrease in HIV viral load. CD4 counts were improved by interventions with interval aerobic or 41-50 minutes of exercise three times per week compared with other modes and duration of exercise. PE appears to benefit PLHIV, but more research is needed to help develop appropriate PE strategies specifically for PLHIV.

Abstract
Background Studies that examine the effectiveness of exercise on quality of life and CD4 cells of HIV population are not easily available in developing countries. Purpose This study was therefore aimed at investigating the effect of 12 weeks aerobic exercise on quality of life and CD4 cells of HIV seropositives in Nigeria. Methods Using convenient sampling, 91 volunteer and willing HIV infected persons were enrolled in the study. Based on inclusion criteria, 82 were eligible for the study, and randomly assigned to control and experimental groups. After determining the baseline values of the variables, the experimental group participated in moderate intensity aerobic exercise for 12 weeks. Weekly lectures were organized for the control group. Attrition rate of 22% was recorded at the end the study, leaving 32 participants in each group. The variables were re-assessed at the end of the Descriptive statistic summarized the socio-demographic characteristics of the participants. Paired Student t-test and Student t-test for two independent samples analyzed the significant difference in mean values of the variables. Results Mean ages in years of the control and experimental groups were39.38 10.03 and 40.84 ± 10.05 respectively, and that of the 64 participants was 39.57±10.13. There was significant improvement (p < 0.05) in the variables between pre- and post-tests in the experimental group. There was insignificant change (p > 0.05) in the four domains of quality of life of the participants, and significant reduction (p < 0.05) in the other four domains of this variable between pre- and post-tests in the control group, in CD4 cell counts, significant improvement was recorded. The variables at the end of the study showed significant difference (p < 0.05) between both groups. Conclusion Quality of life and CD4 cells of HIV seropositives in the experimental group improved significantly after 12 weeks moderate intensity aerobic exercise.

Abstract
The aim of this paper is to use a scoping review to investigate the extent, range, and nature of research on rehabilitation interventions for adults living with HIV. Electronic databases (MEDLINE, EMBASE, CINAHL, AMED, and PsychINFO) and reference lists of the included articles were searched. Authors were emailed when possible for unavailable articles. A total of 897 titles and abstracts were retrieved. Thirty-three articles were included. There were 27 different rehabilitation interventions delivered by 18 professions. The studies were completed in four different countries. Most studies were published in 2008. A randomized-controlled trial was the most used method. The nature of the studies was analyzed according to the three-core concepts of the International Classification of Functioning, Disability and Health: 28 studies addressed impairments; six studies addressed activity limitations; and 14 studies addressed participation restrictions. This scoping study advances the knowledge of research on rehabilitation interventions for adults living with HIV. More research on rehabilitation interventions is needed in sub-Saharan Africa and other low-income and middle-income countries to ensure that these individuals are receiving the best possible care. There is a need for the HIV field to recognize the important contribution of rehabilitation toward the HIV care continuum.

Abstract
Die Effektivität von körperlicher Aktivität in der Primär- als auch Sekundär- und Tertiärprävention ist hinlänglich bekannt. Das Immunsystem spielt eine entscheidende Rolle bei einer Vielzahl von Erkrankungen, da es durch seine Botenfunktion (z. B. durch Zytokine) in einer Vielzahl der Regulationsprozesse mit involviert ist. So kommt es durch moderat-intensive körperliche Aktivität zu einer Stärkung des Immunsystems mit konsekutiv verminderter Infektanfälligkeit sowie eher anti-inflammatorischen Effekten, wohingegen langandauernde und höher intensive Belastungen zu einer Schwächung der Abwehrfunktion sowie einem pro-inflammatorischen Effekt führen. Somit stellt eine adäquat dosierte körperliche Aktivität eine erfolgversprechende Therapieoption bei Erkrankungen des infektiologischen Formenkreises sowie des Immunsystems dar.

Abstract
A randomized controlled trial was conducted to investigate the effects of a 16-week home-based rehabilitation (HBR) intervention on the quality of life, functional mobility, and functional capacity of adult people living with HIV (PLWH) on antiretroviral therapy in KwaZulu-Natal, South Africa. The intervention was carried out by community health care workers under the supervision of a qualified physical therapist. Participants in the control group received the standard of care as well as written health advice. While participants in the intervention group showed greater improvements across all outcome measures, between-group differences were nonsignificant. HBR for PLWH is a safe means of addressing the functional deficits experienced by PLWH and appears likely to improve quality of life. A task-shifting approach may be a feasible method of meeting the varied needs of PLWH, while at the same time potentially minimizing costs to already overburdened health care systems.

Abstract
BACKGROUND People with HIV are living longer with the health-related consequences of HIV, multi-morbidity, and aging. Exercise is a key strategy that may improve or sustain health for people living with HIV. Our aim was to examine the safety and effectiveness of aerobic exercise interventions on immunological, virological, cardiorespiratory, strength, weight, body composition, and psychological outcomes in adults living with HIV. METHODS We conducted a systematic review using the Cochrane Collaboration protocol. We searched databases up to April 2013. We included randomized controlled trials comparing aerobic exercise with no exercise or another intervention performed at least three times per week for at least four weeks among adults living with HIV. Two reviewers independently determined study eligibility. Data were extracted from studies that met inclusion criteria using standardized forms. We assessed risk of bias using the Cochrane Collaboration's tool for assessing risk of bias. Outcomes were analyzed as continuous and meta-analyses conducted using random effects models with Review Manager (RevMan) computer software. RESULTS Twenty-four studies met inclusion criteria (n = 936 participants at study completion); the majority of participants were men (73 %) and the majority were taking antiretroviral therapy (19/24 included studies). The exercise intervention included aerobic exercise alone (11 studies) or a combination of aerobic and resistive exercise (13 studies) ranging from 5 to 52 weeks. Fifty-eight meta-analyses were performed. Main results indicated statistically significant improvements in selected outcomes of cardiorespiratory status (maximum oxygen consumption, exercise time), strength (chest press, knee flexion), body composition (lean body mass, percent body fat, leg muscle area), depression symptoms, and quality of life (SF-36 questionnaire) among exercisers compared with non-exercisers. No significant differences in change in CD4 count and viral load were found. CONCLUSIONS Performing aerobic exercise or a combination of aerobic and resistive exercise at least three times per week for at least five weeks is safe and can lead to improvements in cardiorespiratory fitness, strength, body composition and quality of life for adults with HIV. Aerobic exercise is safe and beneficial for adults living with HIV who are medically stable.

Abstract
BACKGROUND Aerobic endurance is an important aspect of physical fitness that enables individuals living with HIV to endure in the work place as well as in agricultural operations in order to earn a living and improve their quality of life. However, despite high HIV prevalence rates, the aerobic endurance status of young Malawians living with HIV remains unknown. The objective of this study was to determine the difference in VO2max between HIV-negative and HIV-positive individuals in Blantyre, Malawi. METHODS Fifty five participants (17 males and 38 females) who have HIV and were not taking antiretroviral medication and 78 HIV-negative participants (45 males and 33 females) performed the Rockport submaximal treadmill exercise test. Measures of body weight, post-exercise heart rate and time to walk one mile were obtained and used to predict VO2max. Comparisons between groups were adjusted for age differences using analysis of covariance (ANCOVA). RESULTS VO2max was significantly lower in HIV-positive subjects [31.1, 28.7 - 33.5mL.kg-1.min-1(mean, 95% CI)] compared with HIV-negative subjects [56.2, 54.3 - 58.1mL.kg-1.min-1]. CONCLUSION Aerobic endurance was markedly reduced in HIV-positive participants compared with HIV-negative participants. Findings of the current study implicate factors associated with the HIV infection as contributors to a decreased aerobic endurance in people living with HIV.

Abstract
BACKGROUND There is a lack of research investigating long-term effects of exercise training upon the body composition and muscle function in HIV-infected patients (PHIV). The study investigated the influence of a 2-year supervised exercise program on body composition and strength of PHIV under highly active antiretroviral therapy (HAART). METHODS A training program including aerobic, strength and flexibility exercises was performed by 27 PHIV (17 men/ 10 women; age: 48.7±7.0 years; HAART: 150.7±65.3 months) during 1 year and 18 PHIV (10 men/ 8 women; age: 50.6±5.2 years; HAART: 176.6±53.1 months) during 2 years. Body composition and knee isokinetic strength were assessed at baseline and at the end of each year of intervention. RESULTS Body composition remained stable along the whole experiment vs baseline (1-year - total muscle mass: Δ men=1.1%, P=0.21; Δ women=1.4%, P=0.06; trunk fat: Δ men=-0.1%, P=0.65; Δ women=-1.5%, P=0.45; 2 years - total muscle mass: Δ men=2.7%, P=0.54; Δ women=-1.9%, P=0.71; trunk fat: Δ men=4.4%, P=0.96; Δ women=10.0%, P=0.30). After 1-year, peak torque increased in men (Δ extension=4.2%, P=0.01; Δ flexion=12.2%, P=0.04) and total work reduced in women (Δ extension=-15.4%, P=0.01, Δ flexion=-17.5%, P=0.05). All strength markers remained stable vs baseline after 2 years of intervention (P>0.05). Only men showed significant reduction in the risk of disability due to sarcopenia (P=0.05) after 1 year of intervention, which remained stable after 2 years. CONCLUSION Long-term exercise training preserved strength and muscle mass in PHIV under HAART. Exercise programs should be part of HIV therapy to prevent sarcopenia of this population along the years. TRIAL REGISTRATION ACTRN12610000683033; UTN U1111-1116-4416.

Abstract
We examined the association between physical activity (PA), neurocognitive impairment (NCI), and instrumental activities of daily living (IADLs) among older HIV+ persons. One hundred older HIV+ adults completed the International Physical Activity Questionnaire, a neurocognitive battery, and IADL scale. Higher levels of moderate PA were associated with lower odds of NCI (p = 0.01), even when covariates were modeled. The association between moderate PA and NCI was driven by executive function (p = 0.04). Higher levels of moderate PA were also associated with lower odds of IADL Dependence (p = 0.03), although this fell to a trend (p = 0.08) when including covariates. Follow-up analysis showed those with both NCI and IADL Dependence had lower moderate PA than those with neither (p = 0.03). While these cross-sectional findings suggest PA is associated with better neurocognitive and everyday functioning in older HIV+ adults, longitudinal studies utilizing objective PA methods are needed to evaluate directionality and mechanisms.

Abstract
BACKGROUND Low physical activity is associated with depression, which may, in turn, negatively impact antiretroviral therapy (ART) adherence among HIV-infected individuals; however, prior studies have not investigated the relationships between physical inactivity and ART non-adherence. PURPOSE The purpose of this study was to examine the association of physical inactivity, depression, ART non-adherence, and viral load in HIV-infected men who have sex with men. METHODS The sample (N = 860) was from a large, multicenter cohort of HIV-infected patients engaged in clinical care. RESULTS Across time, depression mediated the relationship between physical inactivity and ART non-adherence (γ = 0.075) and the relationship between physical inactivity and viral load (γ = 0.05). ART non-adherence mediated the relationship between depression and viral load (γ = 0.002) and the relationship between physical inactivity and viral load (γ = 0.009). CONCLUSIONS Low levels of physical activity predicted increased depression and poor ART adherence over time, which subsequently predicted higher viral load.

Abstract
People living with HIV (PLWH) are living longer and are at greater risk for chronic comorbidities (e.g., cardiovascular disease, cancer) compared to those not living with HIV. Regular, sustained exercise can prevent and/or mitigate the severity of these comorbidities. Our purpose was to describe patterns of planned exercise implemented in the home setting (i.e., free-living exercise) in PLWH by gender and age. PLWH (n = 102) completed a sociodemographic survey and a 7-day exercise diary documenting daily exercise duration, frequency, and intensity. Women exercised an average of 2.4 (interquartile range [IQR] 0.5-6.0) hours per week compared to men, who exercised 3.5 (IQR 0.5-7.5) hours per week (p = .18). This relationship was particularly evident during middle adulthood for women versus for men (p = .05). PLWH exercised regularly but at less than recommended levels. This is among the first evidence describing free-living exercise patterns of PLWH.

Abstract
With life expectancy increasing and the symptomatology of HIV being altered since the advent of antiretroviral therapy (ART), we now have begun to see metabolic changes with negative implications among people living with HIV/AIDS (PLWHA). Some of these changes include increased blood lipids, central fat accumulation, lipodystrophy, and decreased aerobic capacity. All of which are known risk factors for cardiovascular disease, cancer, and all-cause mortality. A common practice among healthy and other clinical populations to help modify these risk factors is some form of aerobic exercise, resistance exercise, or a combination of both. It has been demonstrated that PLWHA could respond in a similar manner, which in turn may enhance life expectancy and/or quality of life. The purpose of this literature review was to examine the evidence of health benefits of routine exercise training among PLWHA since the advent of ART. Although limited in strength because of small sample sizes and limited intervention durations, there is overall consistency in the general findings. An overview of the findings would indicate that physical activity and exercise are both safe and effective in improving cardiorespiratory fitness, metabolic profile, and quality of life among PLWHA.

Abstract
BACKGROUND Health-Related Quality of Life (HRQoL) and functional exercise capacity are important area of therapeutic interventions needed to improve the general health of People Living with HIV/AIDS (PLWH). However, the relationship between self-report and Performance-based Measure of Functional Capacity (PMFC) of PLWH is still obscure. This study compared the HRQoL and PMFC between a homogenous sample of clinical stage I PLWH and apparently healthy controls. METHODS This case-control study involved 74 consenting participants (37 PLWH and 37 controls) who completed the self-report SF-12 questionnaire and PMFC assessment using Six Minute Walk Test (6MWT). PMFC was expressed in terms of Six-Minute Walk Distance (6MWD), Six-Minute Walk Work (6MWW) and Maximum oxygen uptake (VO2max). Data were analyzed using descriptive statistics of mean and inferential statistics of independent t-test, ANOVA and Pearson's product moment correlation. Alpha level was set at 0.05. RESULTS There was no significant difference in the SF-12 Physical-health Component Score (PCS) of PLWH and the controls (p=0.782). However, the SF-12 Mental-health Component Score (MCS) of PLWH was higher than that of controls (p=0.040). 6MWD, 6MWW and VO2max were significantly lower for PLWH (p<0.05). Among PLWH, there was no significant gender differences in the PMFC (p>0.05) while PCS was higher among females. There was no significant correlation between PMFC variables and each of PCS and MCS for PLWH and controls (p>0.05) respectively. CONCLUSION Self-report physical health of clinical stage 1 PLWH and controls was comparable, while self-report mental health capacity was higher in PLWH than the controls. PMFC of PLWH was significantly lower compared to healthy controls without gender bias. Overall, self-report and performance-based measure of physical functional capacity of PLWH was not inter-related. Therefore understanding the factors that may influence exercise capacity of PLWH may help to develop effective exercise programmes for PLWH.

Abstract
PURPOSE To determine the effects of concurrent strength and endurance training (concurrent training) on the Health-Related Quality of Life (HRQOL) and cardiopulmonary status among HIV-infected patients, using a systematic search strategy of randomized, controlled trials (RCTs). METHODS A systematic review was performed by two independent reviewers using Cochrane Collaboration protocol. The sources used in this review were Cochrane Library, EMBASE, LILACS, MEDLINE, PEDro and Web of Science from 1950 to August 2012. The PEDro score was used to evaluate methodological quality. RESULT Individual studies suggested that concurrent training contributed to improved HRQOL and cardiovascular status. Concurrent training appears to be safe and may be beneficial for medically stable adults living with HIV. The rates of nonadherence were of 16%. CONCLUSION Concurrent training improves the HRQOL and cardiopulmonary status. It may be an important intervention in the care and treatment of adults living with HIV. Further research is needed to determine the minimal and optimal duration, frequency, and intensity of exercise needed to produce beneficial changes in the HIV-infected population subgroups.

Abstract
Several studies have reported the benefits of exercise training for adults with HIV, although there is no consensus regarding the most efficient modalities. The aim of this study was to determine the effects of different types of exercise on physiologic and functional measurements in patients with HIV using a systematic strategy for searching randomized controlled trials. The sources used in this review were the Cochrane Library, EMBASE, MEDLINE, and PEDro from 1950 to August 2012. We selected randomized controlled trials examining the effects of exercise on body composition, muscle strength, aerobic capacity, and/or quality of life in adults with HIV. Two independent reviewers screened the abstracts using the Cochrane Collaboration's protocol. The PEDro score was used to evaluate methodological quality. In total, 29 studies fulfilled the inclusion criteria. Individual studies suggested that exercise training contributed to improvement of physiologic and functional parameters, but that the gains were specific to the type of exercise performed. Resistance exercise training improved outcomes related to body composition and muscle strength, with little impact on quality of life. Aerobic exercise training improved body composition and aerobic capacity. Concurrent training produced significant gains in all outcomes evaluated, although moderate intensity and a long duration were necessary. We concluded that exercise training was shown to be a safe and beneficial intervention in the treatment of patients with HIV.

Abstract
OBJECTIVE The purpose of this study was to compare aerobic function [anaerobic threshold (%VO(2)-AT), respiratory compensation point (%VO(2)-RCP) and peak oxygen uptake (VO(2)peak)] between physically active patients with HIV/AIDS and matched controls and to examine associations between disease status, poor muscle strength, depression (as estimated by the profile of mood states questionnaire) and the aerobic performance of patients. METHODS Progressive treadmill test data for %VO(2)-AT (V-slope method), RCP and (VO(2)peak) were compared between 39 male patients with HIV/AIDS (age 40.6 ± 1.4 years) and 28 male controls (age 44.4 ± 2.1 years) drawn from the same community and matched for habitual physical activity. Within-patient data were also examined in relation to CD4+ counts (nadir and current data) and peak isokinetic knee torque. RESULTS AT, RCP and (VO(2)peak) values were generally similar for patients and controls.Within the patient sample, binary classification suggested that AT, RCP and (VO(2)peak) values were not associated with either the nadir or current CD4+ count, but treadmill test variables were positively associated with peak isokinetic knee torque. CONCLUSION The aerobic performance of physically active patients with HIV/AIDS is generally well conserved. Nevertheless, poor muscle strength is observed in some HIV/AIDS patients, which is associated with lower anaerobic power and (VO(2)peak), suggesting the possibility of enhancing the aerobic performance of patients with weak muscles through appropriate muscle-strengthening activities.

Abstract
BACKGROUND Access to combination antiretroviral therapy has turned HIV into a chronic and manageable disease for many. This increased chronicity has been mirrored by increased prevalence of health-related challenges experienced by people living with HIV (Rusch 2004). Exercise is a key strategy for people living with HIV and by rehabilitation professionals to address these disablements; however, knowledge about the effects of exercise among adults living with HIV still is emerging. OBJECTIVES To examine the safety and effectiveness of aerobic exercise interventions on immunologic and virologic, cardiopulmonary, psychologic outcomes and strength, weight, and body composition in adults living with HIV. SEARCH STRATEGY Searches of MEDLINE, EMBASE, SCIENCE CITATION INDEX, CINAHL, HEALTHSTAR, PsycINFO, SPORTDISCUS and Cochrane Review Group Databases were conducted between 1980 and June 2009. Searches of published and unpublished abstracts and proceedings from major international and national HIV/AIDS conferences were conducted, as well as a handsearch of reference lists and tables of contents of relevant journals and books. SELECTION CRITERIA We included studies of randomised controlled trials (RCTs) comparing aerobic exercise interventions with no aerobic exercise interventions or another exercise or treatment modality, performed at least three times per week for at least four weeks among adults (18 years of age or older) living with HIV. DATA COLLECTION AND ANALYSIS Data on study design, participants, interventions, outcomes, and methodological quality were abstracted from included studies by two reviewers. Meta-analyses, using RevMan 5 computer software, were performed on outcomes when possible. MAIN RESULTS A total of 14 studies met inclusion criteria for this review and 30 meta-analyses over several updates were performed. Main results indicated that performing constant or interval aerobic exercise, or a combination of constant aerobic exercise and progressive resistive exercise for at least 20 minutes at least three times per week for at least five weeks appears to be safe and may lead to significant improvements in selected outcomes of cardiopulmonary fitness (maximum oxygen consumption), body composition (leg muscle area, percent body fat), and psychological status (depression-dejection symptoms). These findings are limited to participants who continued to exercise and for whom there were adequate follow-up data. AUTHORS' CONCLUSIONS Aerobic exercise appears to be safe and may be beneficial for adults living with HIV. These findings are limited by the small sample sizes and large withdrawal rates described in the studies. Future research would benefit from participant follow-up and intention-to-treat analysis. Further research is required to determine the optimal parameters in which aerobic exercise may be most beneficial for adults living with HIV.

Abstract
Individuals infected with HIV experience numerous comorbidities caused by the disease progression and medications, lack of (or inability to perform) physical activity, malnutrition, or a combination of these causes. Common symptoms include loss of muscle mass, fatigue, lypodystrophy, lypoatrophy, and decreases in strength, functional capacity, and overall quality of life. Studies have shown that exercise is a potential treatment of many of these symptoms. Research suggests that exercise may produce beneficial physiological changes in the HIV-infected population such as improved body composition and increases in both strength and endurance. In addition, psychological conditions such as depression and anxiety have been shown to be positively affected by exercise. The purpose of this review is to examine the literature regarding effects of aerobic, resistance, and combined aerobic and resistance exercise training on HIV-infected individuals.

Abstract
BACKGROUND Although the transtheoretical model (TTM) is good at detecting motivation to alter behavior, one of the frequently cited methodological problems is related to the validity of the staging instruments. Few studies have examined the ability of the TTM constructs (decisional balance, self-efficacy, and processes of change) to predict the stages of change in healthy populations, and it has never been applied in this manner among individuals living with HIV/AIDS. PURPOSE To determine the accuracy of the TTM constructs to predict the stages of change for exercise behavior in individuals living with HIV/AIDS. METHODS Cross-sectional self-report data were collected from 208 individuals living with HIV/AIDS. RESULTS Predictive discriminant analysis classified individuals into the correct stages 42% of the time, which was 25% better than chance (Z = 6.79, P < 0.05). Precontemplation was predicted 48% of the time, contemplation 25% of the time, preparation 70% of the time, and maintenance 63% of the time. These four stages were all predicted better than chance alone; however, no one was accurately predicted in the action stage. CONCLUSIONS This was one of the first studies to examine the TTM in individuals living with HIV/AIDS, and the validity of the staging measure among individuals living with HIV/AIDS was supported. However, more research is needed to assess whether the action stage is appropriate for exercise behavior in this population segment.

Abstract
HIV infection and HIV drug therapies result in physical and psychological challenges to those living with HIV. These conditions contribute to decreased functional aerobic capacity (FAC). The aim of this study was to determine the effects of a combined moderate-intensity aerobic and resistance exercise intervention on the FAC of HIV-infected individuals. Forty HIV-infected individuals were randomized to an exercise group (EX) who completed six weeks of moderate-intensity exercise training, or to a control group (CON) that did not receive the exercise intervention. Twice weekly, the EX group completed 30 minutes of moderate-intensity aerobic training followed by moderate-intensity resistance training. Prior to, and following, the intervention the FAC for each subject was determined by graded exercise treadmill stress test (GXT). At baseline testing, the mean FAC as determined by treadmill time-based estimation of maximal oxygen consumption was 25% below age-predicted values, a level of reduction indicating the presence of functional aerobic impairment (FAI). Following the intervention, the EX had a significant increase in time to fatigue and estimated VO(2) max (p<.001). Further, FAI was eliminated (1% above age predicted values) during the exercise training. The EX group also experienced decreased heart rates during Stages 1 (p=.02), 2 (p=.01), 4 (p=.05) and 6 (p=.02) of the GXT. The CON had no significant changes during the intervention period. These data indicate that six weeks of combined moderate-intensity aerobic and resistance training can improve FAC and eliminate FAI in those with HIV. Results suggest that the functional limitations common in HIV-infected individuals are due in part to detraining that is reversible through moderate exercise adherence.

Abstract
Regular physical activity is recommended for patients with human immunodeficiency virus (HIV) to help manage their disease. However, to date, little is known about levels of uptake of this advice. This study describes daily physical activity in HIV antibody-positive patients attending a public hospital infectious diseases clinic, compares them with those of patients attending the clinic for general infectious diseases and investigates compliance with the recommendations of the Centres for Disease Control and Prevention and American College of Sports Medicine physical activity guidelines. During April 2006, 261 patients completed the International Physical Activity Questionnaire short form. One hundred and ninety-one reported being HIV antibody-positive. Results showed that 1:4 HIV antibody-positive and 1:3 HIV antibody-negative respondents failed to meet the recommended guidelines. These findings are of concern, given the evidence-based benefits of regular physical activity. Further work is needed to identify barriers to participation and interventions that can improve uptake.

Abstract
OBJECTIVE Numerous studies document that stress accelerates disease processes in a variety of diseases including HIV. As a result, investigators have developed and evaluated interventions to reduce stress as a means to improve health among persons living with HIV. Therefore, the current meta-analysis examines the impact of stress-management interventions at improving psychological, immunological, hormonal, and other behavioral health outcomes among HIV+ adults. DESIGN This meta-analytic review integrated the results of 35 randomized controlled trials examining the efficacy of 46 separate stress management interventions for HIV+ adults (N=3,077). MAIN OUTCOME MEASURES Effect sizes were calculated for stress processes (coping and social support), psychological/psychosocial (anxiety, depression, distress, and quality of life), immunological (CD4+ counts and viral load), hormonal (cortisol, dehydroepiandrosterone sulfate [DHEA-S], cortisol/DHEA-S ratio, and testosterone) and other behavioral health outcomes (fatigue). RESULTS Compared to controls, stress-management interventions reduce anxiety, depression, distress, and fatigue and improve quality of life (d+s=0.16 to 0.38). Stress-management interventions do not appear to improve CD4+ counts, viral load, or hormonal outcomes compared with controls. CONCLUSION Overall, stress-management interventions for HIV+ adults significantly improve mental health and quality of life but do not alter immunological or hormonal processes. The absence of immunological or hormonal benefits may reflect the studies' limited assessment period (measured typically within 1-week postintervention), participants' advanced stage of HIV (HIV+ status known for an average of 5 years), and/or sample characteristics (predominately male and White participants). Future research might test these hypotheses and refine our understanding of stress processes and their amelioration.

Abstract
OBJECTIVE Our objective was to examine the effects of exercise training (EXS) on quality of life (QoL) in highly active antiretroviral therapy (HAART)-treated HIV-positive (HIV+) subjects with body fat redistribution (BFR) in Rwanda. METHODS The effects of a randomised controlled trial of EXS on QoL were measured using World Health Organisation Quality of Life (WHOQOL)-BREF in HIV+ subjects with BFR randomised to EXS (n = 50; BFR + EXS) or no exercise training (n = 50; BFR + noEXS). RESULTS At 6 months, scores on the psychological [1.3 (0.3) vs. 0.5 (0.1); P < 0.0001], independence [0.6 (0.1) vs. 0.0 (0.0); P < 0.0001], social relationships [0.6 (0.2) vs. 0.0 (0.0); P < 0.0001] and HIV HAART-specific QoL domains [1.4 (0.2) vs. -0.1 (0.2); P < 0.0001] improved more in BFR + EXS than BFR + noEXS group, respectively. Self-esteem [1.3 (0.8) vs. 0.1 (0.6); P < 0.001], body image [1.5 (0.6) vs. 0.0 (0.5); P < 0.001] and emotional stress [1.6 (0.7) vs. 0.2 (0.5); P < 0.001] improved more in the BFR + EXS group than BFR + noEXS group, respectively. Psychological [1.5 (0.2) vs. 1.1 (0.3); P < 0.0001], social relationship [0.8 (0.2) vs. 0.4 (0.2); P < 0.0001], and HIV HAART-specific well-being [1.8 (0.2) vs. 1.0 (0.0); P < 0.0001] improved more in BFR + EXS female than male subjects. CONCLUSIONS Exercise training improved several components of QoL in HAART-treated HIV+ African subjects with BFR. Exercise training is an inexpensive and efficacious strategy for improving QoL in HIV+ African subjects, which may improve HAART adherence and treatment initiatives in resource-limited areas of sub-Saharan Africa.

Abstract
As HAART becomes more accessible in sub-Saharan Africa, metabolic syndromes, body fat redistribution (BFR), and cardiovascular disease may become more prevalent. We conducted a 6-month, randomized controlled trial to test whether cardiorespiratory exercise training (CET), improves metabolic, body composition and cardiorespiratory fitness parameters in HAART-treated HIV(+) African subjects with BFR. Six months of CET reduced waist circumference (-7.13 +/- 4.4 cm, p < 0.0001), WHR (-0.10 +/- 0.1, p < 0.0001), sum skinfold thickness (-6.15 +/- 8.2 mm, p < 0.0001) and % body fat mass (-1.5 +/- 3.3, p < 0.0001) in HIV(+)BFR(+)EXS. Hip circumference was unchanged in non-exercise control groups. CET reduced fasting total cholesterol (-0.03 +/- 1.11 mM, p < 0.05), triglycerides (-0.22 +/-0.48 mM, p < 0.05) and glucose levels (-0.21 +/- 0.71 mM, p < 0.05) (p < 0.0001). HDL-, LDL-cholesterol and HOMA values were unchanged after CET. Interestingly, HIV(+) subjects randomized to non-exercising groups experienced increases in fasting plasma glucose levels, whereas HIV seronegative controls did not (p < 0.001). Predicted VO(2) peak increased more in the HIV(+)BFR(+)EXS than in all other groups (4.7 +/- 3.9 ml/kg/min, p < 0.0001). Exercise training positively modulated body composition and metabolic profiles, and improved cardiorespiratory fitness in HAART-treated HIV(+) Africans. These beneficial adaptations imply that exercise training is a safe, inexpensive, practical, and effective treatment for evolving metabolic and cardiovascular syndromes associated with HIV and HAART exposure in resource-limited sub-Saharan countries, where treatment is improving, morbidity and mortality rates are declining, but where minimal resources are available to manage HIVand HAART-associated cardiovascular and metabolic syndromes.

Abstract
OBJECTIVES Human immunodeficiency virus (HIV) is associated with cardiovascular (CV) and autonomic dysfunction, however the effects of fitness on vascular and autonomic mechanisms in HIV disease are unknown. METHODS We studied forty-eight subjects (40.4 +/- 4.2 years) in a cross-sectional design matched for age, gender, BMI, and fitness. Participants were assigned to 1 in 4 groups: 1) Healthy Unfit (HU), 2) Healthy Fit (HF), 3) HIV Positive Unfit (HPU), and 4) HIV Positive Fit (HPF). Fitness was assessed via open-circuit spirometry; arterial compliance and autonomic modulations were measured via applanation tonometry and power spectral analysis, respectively, and baroreflex sensitivity was obtained using the alpha index. RESULTS Arterial compliance was augmented in HPF vs. HPU [7.4 +/- 1.9 mmHg x second vs. 4.4 +/- 1.7 mmHg x second (P = 0.006)]. Parasympathetic modulation was higher in HPF vs. HPU [2244.5 +/- 2997.6 msecond(2) vs. 489.1 +/- 552.9 msecond(2) (P < 0.05)]. Sympathetic modulation was lower in HPF vs. HU [4.7 +/- 5.0 mmHg(2) vs. 12.9 +/- 9.7 mmHg(2) (P < 0.05)]. Baroreflex sensitivity was higher in HPF vs. HPU [17.3 +/- 10.2 msecond/mmHg vs. 7.4 +/- 3.8 msecond/mmHg (P = 0.003)], and HPF vs. HU [17.3 +/- 10.2 msecond/mmHg vs. 6.2 +/- 3.0 msecond/mmHg (P = 0.004)]. CONCLUSIONS Augmentations in arterial compliance and baroreflex sensitivity associated with fitness portent an improved CV and autonomic profile for HIV-positive individuals. Physical activity may be an adjuvant method to enhance the overall vascular health in HIV-compromised individuals.

Abstract
HIV/AIDS is considered a worldwide pandemic, with continued increases in the number of newly diagnosed cases and persons living long-term with the disease. Athletes may be at risk of infection based on behaviors associated with participation in their sport and away from competition. The sports medicine physician must be aware of the risk of HIV/AIDS in the athlete, diagnosis and treatment options, the effect of HIV/AIDS on exercise, and strategies for prevention of HIV/AIDS in athletic competition.

Abstract
BACKGROUND Women infected with human immunodeficiency virus (HIV) increasingly demonstrate abnormalities in fat distribution and metabolism; however, the effects of a home-based exercise regimen in this group have not been investigated. METHODS We conducted a 16-week randomized intervention study of a supervised home-based progressive resistance training and aerobic exercise program in 40 HIV-infected women with increased waist-hip ratio and self-reported fat redistribution. Cross-sectional muscle area and muscle attenuation were measured by computed tomography. Cardiorespiratory fitness was determined by calculated maximum oxygen consumption (VO2max) and strength by 1-repetition maximum. RESULTS Cardiorespiratory fitness (VO2max) was markedly lower at baseline (median [95% confidence interval], 15.4 [8.3-25.2] mL x kg(-1) x min(-1)) than reported values for healthy female subjects (26-35 mL x kg(-1) x min(-1)). Subjects randomized to exercise had significant improvement in mean +/- SEM VO2max (1.5 +/- 0.8 vs -2.5 +/- 1.6 mL x kg(-1) x min(-1); P<.001) and endurance (1.0 +/- 0.3 vs -0.6 +/- 0.3 minute; P<.001). Strength increased at the knee extensors, pectoralis, knee flexors, shoulder abductors, ankle plantar flexors, and elbow flexors (all P<.001). Total muscle area (6 +/- 1 vs 2 +/- 1 cm2; P = .02) and attenuation (2 +/- 1 vs -1 +/- 1 Hounsfield unit; P = .03) increased in the exercise group. No significant difference was seen in lipid levels, blood pressure, or abdominal visceral fat between the groups, but subjects randomized to exercise reported improved energy and appearance. CONCLUSIONS A 16-week, supervised, home-based exercise regimen improved measures of physical fitness in HIV-infected women. The effects on strength were most significant, but improvements in cardiorespiratory fitness, endurance, and body composition were also seen.

Abstract
PURPOSE Highly active antiretroviral therapy has improved the prognosis of human immuno deficiency virus type 1 (HIV-1)-infected individuals, but it has been associated with the development of metabolic and fat distribution abnormalities known as the lipodystrophy syndrome. This study tested the hypothesis that aerobic exercise training added to a low-lipid diet may have favorable effects in HIV-1-infected individuals with dyslipidemia and lipodystrophy. METHODS Thirty healthy subjects, carriers of HIV-1, with dyslipidemia and lipodystrophy, all of whom were using protease inhibitors and/or non-nucleoside reverse transcriptase inhibitors, were randomly assigned to participate in either a 12-wk program of aerobic exercise or a 12-wk stretching and relaxation program. All subjects received recommendations for a low-lipid diet. Before and after intervention, peak oxygen uptake, body composition, CD4, viral load, lipid profile, and plasma endothelin-1 levels were measured. RESULTS Peak oxygen uptake increased significantly in the diet and exercise group (mean +/- SD: 32 +/- 5 mL x kg(-1) x min(-1) before; 40 +/- 8 mL x kg(-1) x min(-1) after) but not in the diet only group (34 +/- 7 mL x kg(-1) x min(-1) before; 35 +/- 8 mL x kg(-1) x min(-1) after). Body weight, body fat, and waist-to-hip ratio decreased significantly and similarly in the two groups. There were no significant changes in immunologic variables in either group. Likewise, plasma triglycerides, total cholesterol, and HDL cholesterol levels did not change significantly in either group. Plasma endothelin-1 levels were elevated in both groups and presented no significant changes during the study. CONCLUSION HIV-seropositive individuals with lipodystrophy and dyslipidemia submitted to a short-term intervention of low-lipid diet and aerobic exercise training are able to increase their functional capacity without any consistent changes in plasma lipid levels.

Abstract
QUESTION What is the effect of a six-month, supervised, aerobic and resistance exercise program on self-efficacy in men living with human immunodeficiency virus (HIV)? DESIGN Randomised, controlled trial. PARTICIPANTS 40 (5 dropouts) men living with HIV, aged 18 years or older. INTERVENTION The experimental group participated in a twice-weekly supervised aerobic and resistance exercise program for six months and the control group participated in a twice-weekly unsupervised walking program and attended a monthly group forum. OUTCOME MEASURES The primary outcome measure was self-efficacy using the General Self-Efficacy Scale. Secondary outcome measures were cardiovascular fitness using the Kasch Pulse Recovery test, and health-related quality of life using the Medical Outcomes Study HIV Health Survey. Measures were taken by an assessor blinded to group allocation. RESULTS By six months, the experimental group had improved their self-efficacy by 6.8 points (95% CI 3.9 to 9.7, p < 0.001) and improved their cardiovascular fitness by reducing their heart rate by 20.2 bpm (95% CI -25.8 to -14.6, p < 0.001) more than the control group. Health-related quality of life improved in only two out of the eleven dimensions: the experimental group improved their overall health by 20.8 points (95% CI 2.0 to 39.7, p = 0.03) and their cognitive function by 14 points (95% CI 0.7 to 27.3, p = 0.04) more than the control group. CONCLUSION The findings of this study add to the known benefits of exercise for the HIV-infected population.

Abstract
Growth hormone (GH) treatment reverses the muscle loss allegedly responsible for diminished aerobic capacity and increased fatigue in patients with HIV-associated wasting. This study examined whether submaximal measures of physical performance can be used as objective measures of the functional impact of GH treatment-induced anabolism. We randomized 27 HIV-positive men [mean (SD) age, 43.9 (7.2) yr; body mass, 71.9 (10.4) kg; BMI, 23.1 (2.8) kg/m2] with unintentional weight loss despite antiretroviral therapy to receive GH (6 mg) or placebo in a double-blinded, placebo-controlled, cross-over trial with a 3-mo washout. Lean body mass (LBM), maximum oxygen uptake (Vo2 peak), ventilatory threshold (VeT), 6-min walk test (6MWT) distance and work, profile of mood states (POMS) fatigue and vigor scores, and Nottingham health profile (NHP) energy and physical mobility scores were measured. LBM significantly increased after 3 mo of GH treatment vs. placebo (means +/- SE, 3.7 +/- 0.6 vs. 0.3 +/- 0.4 kg; P < 0.001). VeT significantly improved (17.6 +/- 3.7 vs. -5.9 +/- 2.5%; P < 0.001), but Vo2 peak did not change significantly. 6MWT distance improved (24.9 +/- 9.7 vs. 19.9 +/- 11.6 m; P > 0.05) and 6MWT work increased significantly more after 3 mo of GH treatment (33.3 +/- 8.8 vs. 16.5 +/- 7.5 kJ; P < 0.05). POMS scores of fatigue and vigor and the NHP score of energy improved, yet the changes were not statistically significant. GH treatment improved VeT linearly to the increase in LBM (r =0.43, P = 0.037) and 6MWT work (r = 0.51, P = 0.008), and the increase in 6MWT work correlated with increase in LBM (r = 0.45, P = 0.024). Improvement in 6MWT work above the median (27.3 kJ) showed a decrease in fatigue (r = -0.62, P = 0.024). We concluded that GH treatment-induced LBM gains in HIV-associated wasting were functionally relevant, as determined by effort-independent submaximal measures of cardiopulmonary exercise testing.

Abstract
BACKGROUND The profile of HIV infection is constantly changing. Although once viewed as an illness progressing to death, among those with access to antiretroviral therapy, HIV can now present as a disease with an uncertain natural history, perhaps a chronic manageable disease for some. This increased chronicity of HIV infection has been mirrored by increased prevalence of disablement in the HIV-infected population (Rusch 2004). Thus, the needs of these individuals have increasingly included the management of impairments (problems with body function or structure as a significant deviation or loss, such as pain or weakness), activity limitations (difficulties an individual may have in executing activities, such as inability to walk) and participation restrictions (problems an individual may experiences in involvement in life situations, such as inability to work) (WHO 2001). Exercise is a key strategy employed by people living with HIV/AIDS and by rehabilitation professionals to address these issues. Exercise has been shown to improve strength, cardiovascular function and psychological status in seronegative populations (Bouchard 1993), but what are the effects of exercise for adults living with HIV? If the risks and benefits of exercise for people living with HIV are better understood, appropriate exercise may be undertaken by those living with HIV/AIDS and appropriate exercise prescription may be practiced by healthcare providers. If effective and safe, exercise may enhance the effectiveness of HIV management, thus improving the overall outcome for adults living with HIV. OBJECTIVES To examine the safety and effectiveness of aerobic exercise interventions on immunological/virological, cardiopulmonary and psychological parameters in adults living with HIV/AIDS. SEARCH STRATEGY To identify the appropriate studies, we conducted a search using MEDLINE, EMBASE, SCIENCE CITATION INDEX, AIDSLINE, CINAHL, HEALTHSTAR, PSYCHLIT, SOCIOFILE, SCI, SSCI, ERIC and DAI. We also reviewed both published and unpublished abstracts and proceedings from major international and national HIV/AIDS conferences such as the Intersciences Conference on Antimicrobial Agents and Chemotherapy (ICAAC), the Conference on Retroviruses and Opportunistic Infections (CROI), the Infectious Diseases Society of America Conference (IDSA) and the International AIDS Conference (IAC). Reference lists from pertinent articles and books were reviewed and personal contacts with authors were used, as well as Collaborative Review Group databases. Targeted journals were handsearched for relevant articles. There were no language restrictions. Searches for the original review covered the period from 1980 to July 1999. The first update of this review included an additional search of the literature, followed by identification of included studies that met the inclusion criteria from August 1999 to January 2001. For the second update, we conducted a search to identify additional studies published from February 2001 to August 2003. SELECTION CRITERIA Studies were included if they were randomized controlled trials (RCTs) comparing aerobic exercise interventions with no aerobic exercise interventions or another exercise or treatment modality, performed at least three times per week for at least four weeks among adults (18 years of age or older) living with HIV/AIDS. DATA COLLECTION AND ANALYSIS Data on study design, participants, interventions, outcomes and methodological quality were abstracted from studies that met the inclusion criteria onto specifically designed data collection forms by at least two reviewers. Meta-analysis was conducted using RevMan 4.2 computer software on outcomes whenever possible. MAIN RESULTS A total of 10 studies (six from the original search, two from the first updated search and two from this second updated search) met the inclusion criteria for this review. Main results indicated that performing constant or interval aerobic exercise, or a combination of constant aerobic exercise and progressive resistive exercise for at least 20 minutes, at least three times per week for four weeks appears to be safe and may lead to significant reductions in depressive symptoms and potentially clinically important improvements in cardiopulmonary fitness. These findings are limited to those participants who continued to exercise and for whom there was adequate follow-up data. AUTHORS' CONCLUSIONS Aerobic exercise appears to be safe and may be beneficial for adults living with HIV/AIDS. These findings are limited by the small sample sizes and large withdrawal rates of the included studies. Future research would benefit from an increased attention to participant follow-up and intention-to-treat analysis. Further research is required to determine the optimal parameters of aerobic exercise and stage of disease in which aerobic exercise may be most beneficial for adults living with HIV.
