Philip BA, Thompson MR, Baune NA, Hyde M, Mackinnon SE. Failure to Compensate: Patients With Nerve Injury Use Their Injured Dominant Hand, Even When Their Nondominant Is More Dexterous. Arch Phys Med Rehabil 2022; 103:899-907. [PMID: 34728192 PMCID: PMC11034713 DOI: 10.1016/j.apmr.2021.10.010] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 09/02/2021] [Accepted: 10/05/2021] [Indexed: 11/27/2022]
Abstract
OBJECTIVE To identify how individuals respond to unilateral upper extremity peripheral nerve injury via compensation (increased use of the nondominant hand). We hypothesized that injury to the dominant hand would have a greater effect on hand use (left vs right choices). We also hypothesized that compensation would not depend on current (postinjury) nondominant hand performance because many patients undergo rehabilitation that is not designed to alter hand use. DESIGN Observational survey, single-arm. SETTINGS Academic research institution and referral center. PARTICIPANTS A total of 48 adults (N=48) with unilateral upper extremity peripheral nerve injury. Another 14 declined participation. Referred sample, including all eligible patients from 16 months at 1 nerve injury clinic and 1 hand therapy clinic. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Hand use (% of actions with each hand) via Block Building Task. Dexterity via Jebsen-Taylor Hand Function. RESULTS Participants preferred their dominant hand regardless of whether it was injured: hand usage (dominant/nondominant) did not differ from typical adults, regardless of injured side (P>.07), even though most participants (77%) were more dexterous with their uninjured nondominant hand (mean asymmetry index, -0.16±0.25). The Block Building Task was sensitive to hand dominance (P=2 × 10-4) and moderately correlated with Motor Activity Log amount scores (r2=0.33, P<.0001). Compensation was associated only with dominant hand dexterity (P=3.9 × 10-3), not on nondominant hand dexterity, rehabilitation, or other patient and/or injury factors (P>.1). CONCLUSIONS Patients with peripheral nerve injury with dominant hand injury do not compensate with their unaffected nondominant hand, even if it is more dexterous. For the subset of patients unlikely to recover function with the injured hand, they could benefit from rehabilitation that encourages compensation with the nondominant hand.

Exploring the impact of exercise and mind-body prehabilitation interventions on physical and psychological outcomes in women undergoing breast cancer surgery. Support Care Cancer 2021; 30:2027-2036. [PMID: 34648061 DOI: 10.1007/s00520-021-06617-8] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Accepted: 10/03/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE To compare the impact of exercise and mind-body prehabilitation interventions on changes in quality of life and cancer treatment-related symptoms in women with newly diagnosed breast cancer. METHODS The following describes a secondary analysis of a randomized window of opportunity trial (The Pre-Operative Health and Body Study). Forty-nine women were randomized to participate in either an exercise prehabilitation intervention or a mind-body prehabilitation intervention from the time of enrollment to surgery. Participants (N = 47) completed measures of quality of life, anxiety, depression, and stress at the time of enrollment (T1), post-intervention/surgery (T2), and one-month post-surgery (T3). Changes in outcome measures between groups were compared over time using longitudinal models. RESULTS Mind-body group participants experienced significant improvements in cognitive functioning in comparison to exercise group participants between T1 and T3 (difference in average change: -9.61, p = 0.04, d = 0.31), otherwise, there were no significant differences between groups. Within group comparisons demonstrated that both groups experienced improvements in anxiety (exercise: average change = -1.18, p = 0.03, d = 0.34; mind-body: average change = -1.69, p = 0.006, d = 0.43) and stress (exercise: average change = -2.33, p = 0.04, d = 0.30; mind-body: average change = -2.59, p = 0.05, d = 0.29), while mind-body group participants experienced improvements in insomnia (average change = -10.03, p = 0.04, d = 0.30) and cognitive functioning (average change = 13.16, p = 0.0003, d = 0.67). CONCLUSIONS Both prehabilitation interventions impacted cancer treatment-related symptoms. Further work in larger groups of patients is needed to evaluate the efficacy of prehabilitation interventions on quality of life in women with breast cancer. Pre-operative exercise and mind-body interventions may impact physical and/or psychological effects of cancer diagnosis and treatment in women with breast cancer.

The roles of closeness, marital behavior, and age in spouses' cardiometabolic similarity. Psychoneuroendocrinology 2020; 120:104777. [PMID: 32623020 PMCID: PMC7849824 DOI: 10.1016/j.psyneuen.2020.104777] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2020] [Revised: 06/12/2020] [Accepted: 06/15/2020] [Indexed: 11/30/2022]
Abstract
Spouses share common risks for cardiometabolic diseases: a person's diabetes or hypertension raises the partner's odds of developing the same condition. The mechanisms responsible for this disease concordance remain poorly understood. To examine three factors that may modulate partners' cardiometabolic similarity-closeness, hostile marital behavior, and age-and to explore whether health behavior concordance plays a role, on two separate occasions 43 healthy couples ages 24-61 provided fasting glucose, metabolic data (fat and carbohydrate oxidation), and resting blood pressure before discussing one of their most severe marital disagreements. Accounting for the fixed effects of sex, age, study visit, and abdominal fat on cardiometabolic levels, we found that aspects of health behavior concordance were associated with greater similarity in glucose, diastolic blood pressure (DBP), and carbohydrate and fat metabolism. Independent of health behavior concordance, partners who felt closer and behaved in a less hostile way had more similar rates of fat oxidation; less hostile partners also shared greater overlap in carbohydrate oxidation. Likewise, fasting glucose and DBP were more similar within older couples compared to younger pairs, beyond the effects of health behavior concordance. In sum, our data captured preclinical similarities in cardiometabolic health among disease-free couples, which may form the basis for their long-term overlapping disease risks. Closer, less hostile, and older couples shared more similar fasting glucose, metabolic data, and blood pressure; importantly, health behavior concordance did not explain all associations. These novel data suggest that multiple paths may lead to couples' shared disease risks.

Abstract
Objective: To assess the feasibility, safety, and preliminary effect of a 12-week
multi-modal rehabilitation program targeted at improving health-related
quality of life and physical activity levels of patients with lung cancer
following treatment. Methods: Patients with stage I to IIIA non-small cell lung cancer were included 6 to
12 weeks following completion of treatment. The intervention comprised of
aerobic exercise (brisk walking), resistance training and 8-style Tai Chi.
The 12-week program included 2 supervised center-based sessions per week of
90 minutes duration and home-based exercise. The primary outcomes were the
feasibility and safety of the intervention. Secondary outcomes (assessed pre
and post program) were physical and patient-reported outcomes. Results: Seventy-eight patients were approached during the 6-month recruitment period
and 17 (22%) consented to the study. Eight participants (47%) met the
definition of adherence to the program (attending at least 70% of supervised
sessions). No serious adverse events occurred. A significant reduction in
anxiety and depression was observed post-program. In addition, improvements
in respiratory function, sleep quality, and some health-related quality of
life domains were observed post-program. There were no significant
differences in functional capacity or physical activity levels. Conclusion: This multi-modal exercise training program was safe, although the feasibility
of the program in its current state is not supported given the low consent
rate and low adherence to the intervention.

Abstract
Background Observational data support inverse relationships between exercise or metformin use and disease outcomes in colorectal and breast cancer survivors, although the mechanisms underlying these associations are not well understood. Methods In a phase II trial, stage I–III colorectal and breast cancer survivors who completed standard therapy were randomly assigned to structured exercise or metformin or both or neither for 12 weeks. The primary outcome was change in fasting insulin levels; secondary outcomes included changes in other blood-based energetic biomarkers and anthropometric measurements. Analyses used linear mixed models. Results In total, 139 patients were randomly assigned; 91 (65%) completed follow-up assessments. Fasting insulin levels statistically significantly decreased in all three intervention arms (−2.47 μU/mL combination arm, −0.08 μU/mL exercise only, −1.16 μU/mL metformin only, + 2.79 μU/mL control arm). Compared with the control arm, all groups experienced statistically significant weight loss between baseline and 12 weeks (−1.8% combination arm, −0.22% exercise only, −1.0% metformin only, +1.55% control). The combination arm also experienced statistically significant improvements in the homeostatic model assessment for insulin resistance (−30.6% combination arm, +61.2% control) and leptin (−42.2% combination arm, −0.8% control), compared with the control arm. The interventions did not change insulin-like growth factor–1 or insulin-like growth factor binding protein–3 measurements as compared with the control arm. Tolerance to metformin limited compliance (approximately 50% of the participants took at least 75% of the planned dosages in both treatment arms). Conclusions The combination of exercise and metformin statistically significantly improved insulin and associated metabolic markers, as compared to the control arm, with potential greater effect than either exercise or metformin alone though power limited formal synergy testing. Larger efforts are warranted to determine if such a combined modality intervention can improve outcomes in colorectal and breast cancer survivors.

Abstract
Lower limb endurance training can improve conduit artery flow-mediated dilation (FMD) in response to transient increases in shear stress (reactive hyperemia; RH-FMD) in both the upper and lower limbs. Sustained increases in shear stress recruit a partially distinct transduction pathway and elicit a physiologically relevant FMD response (SS-FMD) that provides distinct information regarding endothelial function. However, the impact of training on SS-FMD is not well understood. The purpose of this study was to determine the impact of cycling training on handgrip exercise-induced brachial artery (BA) FMD (BA SS-FMD) and calf plantar-flexion-induced superficial femoral artery (SFA) FMD (SFA SS-FMD). RH-FMD was also assessed in both arteries. Twenty-eight young males were randomized to control (n = 12) or training (n = 16) groups. The training group cycled 30 min/day, 3 days/week for 4 weeks at 80% heart rate reserve. FMD was assessed in the BA and SFA before and after the intervention via Duplex ultrasound. Results are means ± SD. Training did not impact SS-FMD in either artery, and SFA RH-FMD was also unchanged (p > 0.05). When controlling for the shear rate stimulus via covariate analysis, BA RH-FMD improved in the training group (p = 0.05) (control - pre-intervention: 5.7% ± 2.4%, post-intervention: 5.3% ± 2.4%; training - pre-intervention: 5.4% ± 2.5%, post-intervention: 7.2% ± 2.4%). Thus, endurance training resulted in nonuniform adaptations to endothelial function, with an isolated impact on the BA's ability to transduce a transient increase in shear stress. Novelty Training did not alter SS-FMD in the arm or leg. RH-FMD was augmented in the arm only. Thus training adaptations were limb- and shear stress profile-specific.

Abstract
BACKGROUND This systematic review examined the methodological quality of studies and assessed the psychometric qualities of interview-administered Past-week and Usual-week Physical Activity Questionnaires (PAQs). Pubmed and Embase were used to retrieve data sources. METHODS The studies were selected using the following eligibility criteria: 1) psychometric properties of PAQs were assessed in adults; 2) the PAQs either consisted of recall periods of usual 7-days (Usual-week PAQs) within the past 12 months or during the past 7-days (Past-week PAQs); and 3) PAQs were interview-administered. The COSMIN taxonomy was utilised to critically appraise study quality and a previously established psychometric criteria employed to evaluate the overall psychometric qualities. RESULTS Following screening, 42 studies were examined to determine the psychometric properties of 20 PAQs, with the majority of studies demonstrating good to excellent ratings for methodological quality. For convergent validity (i.e., the relationship between PAQs and other measures), similar overall associations were found between Past-week PAQs and Usual-week PAQs. However, PAQs were more strongly associated with direct measures of physical activity (e.g., accelerometer) than indirect measures of physical activity (i.e., physical fitness), irrespective of recall methods. Very few psychometric properties were examined for each PAQ, with the majority exhibiting poor ratings in psychometric quality. Only a few interview-administered PAQs exhibited positive ratings for a single psychometric property, although the other properties were either rated as poor or questionable, demonstrating the limitations of current PAQs. CONCLUSION Accordingly, further research is necessary to explore a greater number of psychometric properties, or to develop new PAQs by addressing the psychometric limitations identified in the current review.

Abstract
Growing evidence indicates that strawberries are cardioprotective. We conducted an eight-week randomized, double-blind, placebo-controlled, parallel arm clinical trial to investigate the effects of daily consumption of freeze-dried strawberry powder (FDSP) on blood pressure (BP) and arterial stiffness in pre- and stage 1-hypertensive postmenopausal women. Sixty postmenopausal women were randomly assigned to one of three groups: (1) control, (2) 25 g FDSP and (3) 50 g FDSP (n = 20 per group). Assessments of body weight, BP, arterial stiffness as measured by pulse wave velocity (PWV), and collection of blood samples for analyses of vasoactive and antioxidant molecules were performed at baseline, four and eight weeks. After eight weeks, systolic BP, as well as brachial- and femoral-ankle PWV were lower than baseline in the 25 g FDSP group (141 ± 3 to 135 ± 3 mmHg, P = 0.02; 15.5 ± 0.5 to 14.8 ± 0.4 m s-1, P = 0.03, and 11.0 ± 0.2 to 10.4 ± 0.2 m s-1, P = 0.02, respectively), whereas no statistically significant changes were observed in the control or 50 g FDSP groups. Plasma nitric oxide metabolite levels increased at four and eight weeks in the 50 g FDSP group compared to baseline (8.5 ± 1.2 to 13.6 ± 1.3 and 13.3 ± 1.5, respectively, P = 0.01), whereas no significant changes were observed in the control or 25 g FDSP groups. Serum levels of superoxide dismutase increased at four weeks returning to baseline levels at eight weeks in all three groups. Significant differences among groups were not detected for any of the parameters. Although BP and arterial stiffness improved in the 25 g FDSP group over time, a treatment effect was not observed. Thus, it would be premature to affirm that daily consumption of FDSP improves BP or vascular function in pre- and stage 1-hypertensive postmenopausal women. This trial was registered at as NCT02099578.

Abstract
There have been few studies concerning the relationship between exercise habits and lipid levels of older adults. This study examines this relationship using data from 117 healthy older adults who volunteered to participate in a health promotion project. Responses to a seven-day activity recall questionnaire, percentage of body fat as measured by bioelectric impedance, age, and gender were used to predict total cholesterol, HDL, LDL, and triglyceride levels. Only the model predicting HDL was significant (R2=. 15, p = .002). Subsequent regression analyses predicting HDL levels were limited to persons who participated in one or more exercise sessions in the previous week. For these active women, the model's ability to predict HDL improved (R2= .37,p = .005), with exercise level having the greatest effect. For the active men, the model's predictive ability was not significant. The findings suggest that for active women, level of physical activity does modestly influence HDL levels.

Abstract
Self-reports of levels of physical exercise, experienced bodily changes, and attitudinal and well-being variables were obtained from 407 adults, aged 26 to 95 years. The purpose was to assess the relative magnitudes of the experienced benefits of exercise across the exercise continuum. Cluster analyses identified three groups at each of four age levels: a) sedentary people who experienced negative bodily changes; b) modest exercisers who reported the most positive bodily changes; and c) high exercisers who reported only minimal bodily changes. Psychological barriers to exercise among sedentary people included negative exercise attitudes, attributions of negative bodily changes to aging, and low levels of exercise motivation and self-efficacy. Modest and high exercisers both scored high on attitude and well-being variables.

Examination of fitness status by ethnicity indicated a higher level of fitness among White females. Ethnic differences were found on 2 of 6 exercise belief items and 2 of 3 exercise knowledge questions. A multiple regression analysis found that activity level was predicted by the knowledge question concerning heart rate during exercise necessary to maintain fitness, the belief concerning the difficulty "to stick to a regular schedule of physical activity," and the belief concerning the difficulty "to find the time to exercise on a regular basis." The findings suggest that health promotion efforts need to determine exercise attitudes and beliefs of older women, provide basic exercise knowledge, and include fitness programs designed specifically for older women.

Abstract
Although Blair's 7-Day Activity Interview (AI) has been widely used in epidemiological studies among adults, this instrument lacked a level of sensitivity when used among older adults with low functional capacities. To resolve this limitation, the AI was modified by adjusting the activity intensity categories to assess low-intensity activities. Concurrent and construct validity of the Modified AI were evaluated in groups of older adults known to differ in activity. The Active Group (N = 30) exercised 3 days per week, whereas the Inactive Group (N = 30) did not participate in extracurricular exercise. Energy expenditures calculated using the Modified AI discriminated between the active and inactive groups (p < .0001). The Modified AI was found to have concurrent validity, that is, older adults who exercised regularly had significantly higher energy expenditures (p < .0001). The Modified AI assesses low-intensity activity and was shown to have concurrent and construct validity among these groups of older adults.

Abstract
BACKGROUND Exercise helps individuals with prediabetes or type 2 diabetes (T2D) manage their blood glucose (BG); however, exercise adherence in this population is dismal. In this pilot study we tested the efficacy of a self-monitoring group-based intervention using continuous glucose monitors (CGMs) at increasing exercise adherence in individuals with impaired BG. MATERIALS AND METHODS Thirteen participants with prediabetes or T2D were randomized to an 8-week standard care exercise program (CON condition) (n = 7) or self-monitoring exercise intervention (SM condition) (n = 6). Participants in the SM condition were taught how to self-monitor their exercise and BG, to goal set, and to use CGM to observe how exercise influences BG. We hypothesized that compared with the CON condition, using a real-time CGM would facilitate self-monitoring behavior, resulting in increased exercise adherence. RESULTS Repeated-measures analysis of variance revealed significant Condition × Time interactions for self-monitoring (P < 0.01), goal setting (P = 0.01), and self-efficacy to self-monitor (P = 0.01), such that the SM condition showed greater increases in these outcomes immediately after the program and at the 1-month follow-up compared with the CON condition. The SM condition had higher program attendance rates (P = 0.03), and a greater proportion of participants reregistered for additional exercise programs (P = 0.048) compared with the CON condition. Participants in both conditions experienced improvements in health-related quality of life, waist circumference, and fitness (P values <0.05). CONCLUSIONS These findings provide promising initial support for the use of a real-time CGM to foster self-monitoring and exercise behavior in individuals living with prediabetes or T2D.

Abstract
Heat balance in humans is maintained at near constant levels through the adjustment of physiological mechanisms that attain a balance between the heat produced within the body and the heat lost to the environment. Heat balance is easily disturbed during changes in metabolic heat production due to physical activity and/or exposure to a warmer environment. Under such conditions, elevations of skin blood flow and sweating occur via a hypothalamic negative feedback loop to maintain an enhanced rate of dry and evaporative heat loss. Body heat storage and changes in core temperature are a direct result of a thermal imbalance between the rate of heat production and the rate of total heat dissipation to the surrounding environment. The derivation of the change in body heat content is of fundamental importance to the physiologist assessing the exposure of the human body to environmental conditions that result in thermal imbalance. It is generally accepted that the concurrent measurement of the total heat generated by the body and the total heat dissipated to the ambient environment is the most accurate means whereby the change in body heat content can be attained. However, in the absence of calorimetric methods, thermometry is often used to estimate the change in body heat content. This review examines heat exchange during challenges to heat balance associated with progressive elevations in environmental heat load and metabolic rate during exercise. Further, we evaluate the physiological responses associated with heat stress and discuss the thermal and nonthermal influences on the body's ability to dissipate heat from a heat balance perspective.

Abstract
Background Organised follow-up is a common feature of several strategies at the primary health care level to promote health behaviour change, e.g. to increase physical activity. In Norway, municipal ‘healthy living’ centres run by health care personnel are established to offer counselling and organised follow-up of health behaviour change during a 12-week programme. We report the results of a systematic review commissioned by the Norwegian Directorate of Health concerning organised follow-up to improve physical activity. Methods We searched ten electronic databases up to June 2012, reference lists of included publications, and relevant journals. Study selection and quality risk of bias assessment were carried out independently. Data were synthesised narratively due to heterogeneity of measurements of physical activity. The GRADE approach was used to assess our confidence in the effect estimate for each outcome in each comparison. Results Fourteen randomised controlled trials from seven countries and with a total of 5,002 participants were included in the systematic review. All studies were carried out in primary care or community settings. The interventions comprised referral to supervised group physical activity (2 studies), referral to local resources with follow-up (6 studies), and self-organised physical activity with follow-up (6 studies). The narrative synthesis, comprising a total of 39 comparisons, indicated effects of self-organised physical activity with follow-up (compared to both advice and no treatment) and referral to local resources with follow-up (compared to advice) in some of the comparisons where we rated our confidence in the effect estimates as moderate. However, the results indicated no difference between intervention and control groups for the majority of comparisons. Follow-up in the studies was mainly short-term with the longest follow-up 9 months post-treatment. We rated our confidence in the effect estimates as low or very low in most comparisons, both for positive and neutral results. Conclusions The results of this systematic review indicate considerable uncertainty concerning effects of organised follow-up during 10–14 weeks on physical activity. Major methodological problems concerning the measurement of physical activity are discussed. Trial registration Systematic review registration: PROSPERO CRD42011001598.

Abstract
Objective. To assess the effectiveness of workplace interventions in improving physical activity. Data Source. EBSCO research database (and all subdatabases). Study Inclusion and Exclusion Criteria. Articles were published from 2000 to 2010 in English, had appropriate designs, and measured employees' physical activity, energy consumption, and/or body mass index (BMI) as primary outcomes. Articles that did not meet the inclusion criteria were excluded. Data Extraction. Data extracted included study design, study population, duration, intervention activities, outcomes, and results. Data Synthesis. Data were synthesized into one table. Results of each relevant outcome including p values were combined. Results. Twelve (60%) of 20 selected interventions reported an improvement in physical activity level, steps, or BMI, and there was one slowed step reduction in the intervention group. Among these, 10 were less than 6 months in duration; 9 used pedometers; 6 applied Internet-based approaches; and 5 included activities targeting social and environmental levels. Seven of 8 interventions with pre-posttest and quasi-experimental controlled design showed improvement on at least one outcome. However, 7 of 12 randomized controlled trials (RCTs) did not prove effective in any outcome. Conclusion. Interventions that had less rigorous research designs, used pedometers, applied Internet-based approaches, and included activities at social and environmental levels were more likely to report being effective than those without these characteristics.

Abstract
AIMS Poor health and well-being has been observed among NHS staff and has become a key focus in current public health policy. The objective of this study was to deliver and evaluate a five-year employee wellness programme aimed at improving the health and well-being of employees in a large NHS workplace. METHOD A theory-driven multi-level ecological workplace wellness intervention was delivered including health campaigns, provision of facilities and health-promotion activities to encourage employees to make healthy lifestyle choices and sustained behaviour changes. An employee questionnaire survey was distributed at baseline (n = 1,452) and at five years (n = 1,134), including measures of physical activity, BMI, diet, self-efficacy, social support, perceived general health and mood, smoking behaviours, self-reported sickness absence, perceived work performance and job satisfaction. RESULTS Samples were comparable at baseline and follow-up. At five years, significantly more respondents actively travelled (by walking or cycling both to work and for non-work trips) and more were active while at work. Significantly more respondents met current recommendations for physical activity at five years than at baseline. Fewer employers reported 'lack of time' as a barrier to being physically active following the intervention. Significantly lower sickness absence, greater job satisfaction and greater organisational commitment was reported at five years than at baseline. CONCLUSIONS Improvements in health behaviours, reductions in sickness absence and improvements in job satisfaction and organisational commitment were observed following five years of a workplace wellness intervention for NHS employees. These findings suggest that health-promoting programmes should be embedded within NHS infrastructure.

Abstract
Blunting of sympathetic vasoconstriction in exercising muscle is well-established. Whether it persists during the early post-exercise period is unknown. This study tested the hypothesis that it persists in human skeletal muscle during the first 10 min of recovery from exercise. Eight healthy young males (21.4 ± 0.8 yrs, SE) performed 7 min of forearm rhythmic isometric handgrip exercise at 15% below forearm critical force (fCF). In separate trials, a cold pressor test (CPT) of 2 min duration was used to evoke forearm sympathetic vasoconstriction in each of Rest (R), Steady State Exercise (Ex), 2-4 min Post-Exercise (PEearly), and 8-10 min Post-Exercise (PElate). A 7 min control exercise trial with no CPT was also performed. Exercising forearm brachial artery blood flow, arterial blood pressure, cardiac output (CO), heart rate (HR), forearm deep venous catecholamine concentration, and arterialized venous catecholamine concentration were obtained immediately prior to and following the CPT in each trial. CPT resulted in a significant increase in forearm venous plasma norepinephrine concentration in all trials (P = 0.007), but no change in arterialized plasma norepinephrine (P = 0.32). CPT did not change forearm venous plasma epinephrine (P = 0.596) or arterialized plasma epinephrine concentration (P = 0.15). As assessed by the %reduction in forearm vascular conductance (FVC) the CPT evoked a robust vasoconstriction at rest that was severely blunted in exercise (R = -39.9 ± 4.6% vs. Ex = 5.5 ± 7.4%, P < 0.001). This blunting of vasoconstriction persisted at PEearly (-12.3 ± 10.1%, P = 0.02) and PElate (-18.1 ± 8.2%, P = 0.03) post-exercise. In conclusion, functional sympatholysis remains evident in human skeletal muscle as much as 10 min after the end of a bout of forearm exercise. Persistence of functional sympatholysis may have important implications for blood pressure regulation in the face of a challenge to blood pressure following exercise.

Abstract
Depression, the most common type of mental illness, is the second leading cause of disability and is increasing among Americans. The effect of improved nutrition, particularly with dietary supplements, on depression may provide an alternative to standard medical treatment. Some studies have shown that certain nutrients (e.g., inositol and S-adenosyl methionine) are effective at improving depressed mood, although the results are not unequivocal. The current study was a randomized, double-blind, placebo-controlled trial to evaluate the efficacy of a vitamin B complex nutritional supplement (Max Stress B) for improving depressive and anxiety symptoms according to the Beck Depression and Anxiety Inventories (BDI and BAI) in 60 adults diagnosed with major depression or other forms of depressive disorders. Secondary outcomes included quality of life according to the SF-36. Participants were assessed at baseline and 30- and 60-day followups.
Max Stress B showed significant and more continuous improvements in depressive and anxiety symptoms, compared to placebo. Additionally, Max Stress B showed significant improvement on the mental health scale of the SF-36 compared to placebo. Thus, we showed modest utility of Max Stress B to improve mood symptoms and mental health quality of life in adults with depression.

Abstract
BACKGROUND Evidence suggests that consumption of apple or its bioactive components modulate lipid metabolism and reduce the production of proinflammatory molecules. However, there is a paucity of such research in human beings. OBJECTIVE Women experience a lower rate of cardiovascular disease before menopause compared with men. However, after the onset of menopause, the risk of cardiovascular disease increases drastically due to ovarian hormone deficiency. Hence, we conducted a 1-year clinical trial to evaluate the effect of dried apple vs dried plum consumption in reducing cardiovascular disease risk factors in postmenopausal women. DESIGN One-hundred sixty qualified postmenopausal women were recruited from the greater Tallahassee, FL, area during 2007-2009 and were randomly assigned to one of two groups: dried apple (75 g/day) or dried plum (comparative control). Fasting blood samples were collected at baseline, 3, 6, and 12 months to measure various parameters. Physical activity recall and 7-day dietary recall were also obtained. RESULTS Neither of the dried fruit regimens significantly affected the participants' reported total energy intake throughout the study period. On the contrary, women who consumed dried apple lost 1.5 kg body weight by the end of the study, albeit not significantly different from the dried plum group. In terms of cholesterol, serum total cholesterol levels were significantly lower in the dried apple group compared with the dried plum group only at 6 months. Although dried plum consumption did not significantly reduce serum total cholesterol and low-density lipoprotein cholesterol levels, it lowered their levels numerically by 3.5% and 8%, respectively, at 12 months compared with baseline. This may explain the lack of significance observed between the groups. However, within the group, women who consumed dried apple had significantly lower serum levels of total cholesterol and low-density lipoprotein cholesterol by 9% and 16%, respectively, at 3 months compared with baseline. These serum values were further decreased to 13% and 24%, respectively, after 6 months but stayed constant thereafter. The within-group analysis also reported that daily apple consumption profoundly improved atherogenic risk ratios, whereas there were no significant changes in lipid profile or atherogenic risk ratios as a result of dried plum consumption. Both dried fruits were able to lower serum levels of lipid hydroperoxide and C-reactive protein. However, serum C-reactive protein levels were significantly lower in the dried plum group compared with the dried apple group at 3 months. CONCLUSIONS There were no significant differences between the dried apple and dried plum groups in altering serum levels of atherogenic cholesterols except total cholesterol at 6 months. However, when within treatment group comparisons are made, consumption of 75 g dried apple (about two medium-sized apples) can significantly lower atherogenic cholesterol levels as early as 3 months. Furthermore, consumption of dried apple and dried plum are beneficial to human health in terms of anti-inflammatory and antioxidative properties.

Abstract
CONTEXT Weight gain after kidney transplantation affects 50% to 90% of kidney transplant recipients. Factors leading to weight gain in recipients are thought to include a change in lifestyle (eg, dietary intake and physical activity), age, race, sex, and immunosuppressant medications. OBJECTIVE To examine dietary intake and physical activity of kidney transplant recipients at baseline and 3 and 6 months after transplantation to identify contributing factors to weight gain. DESIGN Descriptive, correlational study using secondary data from a larger parent study examining genetic and environmental contributors to weight gain after kidney transplantation. PARTICIPANTS AND SETTING Forty-four kidney transplant recipients at a mid-South university hospital-based transplant institute who had dietary intake, physical activity, and clinical data at baseline and 3 and 6 months were included. MAIN OUTCOME MEASURES Dietary intake, physical activity, weight, and body mass index. RESULTS Mean weight gain increased by 6% from baseline to 6 months. Interestingly, dietary intake did not change significantly from baseline to 6 months. Hours of sleep per day decreased during the same period (P = .02). Dietary intake, physical activity, age, race, sex, and immunosuppression showed no significant relationship to weight gain at 6 months. CONCLUSION Little consideration has been given to dietary intake and physical activity of kidney transplant recipients and the effects of these variables on weight gain. Further studies with a larger sample are needed, as weight gain after transplantation is a significant risk factor for diminished long-term outcomes.

Abstract
Observational studies demonstrate an association between physical activity and improved outcomes in breast and colon cancer survivors. To test these observations with a large, randomized clinical trial, an intervention that significantly impacts physical activity in these patients is needed. The Active After Cancer Trial (AACT) was a multicenter pilot study evaluating the feasibility of a telephone-based exercise intervention in a cooperative group setting. Sedentary (engaging in <60 min of recreational activity/week) breast and colorectal cancer survivors were randomized to a telephone-based exercise intervention or usual care control group. The intervention was delivered through the University of California at San Diego; participants received ten phone calls over the course of the 16-week intervention. All participants underwent assessment of physical activity, fitness, physical functioning, fatigue and exercise self-efficacy at baseline and after the 16-week intervention. One hundred and twenty-one patients were enrolled through ten Cancer and Leukemia Group B (CALGB) institutions; 100 patients had breast cancer and 21 had colorectal cancer. Participants randomized to the exercise group increased physical activity by more than 100 versus 22% in controls (54.5 vs. 14.6 min, P = 0.13), and experienced significant increases in fitness (increased 6-min walk test distance by 186.9 vs. 81.9 feet, P = 0.006) and physical functioning (7.1 vs. 2.6, P = 0.04) as compared to the control group. Breast and colorectal cancer survivors enrolled in a multicenter, telephone-based physical activity intervention increased physical activity and experienced significant improvements in fitness and physical functioning. Lifestyle intervention research is feasible in a cooperative group setting.

Abstract
Observational studies have linked lower omega-3 (n-3) polyunsaturated fatty acids (PUFAs) and higher omega-6 (n-6) PUFAs with inflammation and depression, but randomized controlled trial (RCT) data have been mixed. To determine whether n-3 decreases proinflammatory cytokine production and depressive and anxiety symptoms in healthy young adults, this parallel group, placebo-controlled, double-blind 12-week RCT compared n-3 supplementation with placebo. The participants, 68 medical students, provided serial blood samples during lower-stress periods as well as on days before an exam. The students received either n-3 (2.5 g/d, 2085 mg eicosapentaenoic acid and 348 mg docosahexanoic acid) or placebo capsules that mirrored the proportions of fatty acids in the typical American diet. Compared to controls, those students who received n-3 showed a 14% decrease in lipopolysaccharide (LPS) stimulated interleukin 6 (IL-6) production and a 20% reduction in anxiety symptoms, without significant change in depressive symptoms. Individuals differ in absorption and metabolism of n-3 PUFA supplements, as well as in adherence; accordingly, planned secondary analyses that used the plasma n-6:n-3 ratio in place of treatment group showed that decreasing n-6:n-3 ratios led to lower anxiety and reductions in stimulated IL-6 and tumor necrosis factor alpha (TNF-α) production, as well as marginal differences in serum TNF-α. These data suggest that n-3 supplementation can reduce inflammation and anxiety even among healthy young adults. The reduction in anxiety symptoms associated with n-3 supplementation provides the first evidence that n-3 may have potential anxiolytic benefits for individuals without an anxiety disorder diagnosis.

Abstract
The measurement of daily physical activity (PA) has become a significant outcome in patients with chronic obstructive pulmonary disease (COPD). Recent data have shown the independent association between PA markers, hospitalizations, and mortality. Daily PA can be quantified by direct observation, assessment of energy expenditure, questionnaires, and activity monitors (motion sensors). This review aims to describe the methods used to quantify daily PA in COPD on the basis of the published literature and to suggest potential applications of activity monitoring methods in clinical research and daily care of COPD patients.

Abstract
Using the theoretical context of the Theory of Planned Behaviour, this study examined whether work has a disruptive influence on people's ability to carry out their daily intentions to exercise, and whether daily planning helps overcome this. A daily questionnaire was completed by 42 employees for 14 days. A brief daily planning intervention was administered to half of the employees. Multilevel modelling was used to analyse the data. The moderating effects of daily perceived behavioural control (PBC), job demands and work-related anxiety and depression on the relationship between intention to exercise and subsequent behaviour were investigated, as well as the impact of the intervention. Intention and PBC predicted exercise. Job demands appeared to disrupt people's ability to carry out their daily exercise intentions. Contrary to expectation, people in the no intervention group were more likely to exercise. Furthermore, on low-demand days they were most successful in realising their exercise intentions (when they intended to exercise for longer), whereas people in the intervention group, on high-demand days were least successful in realising their exercise intentions. The intervention may have operated contrary to expectation by drawing attention to potential failure.

Abstract
Migrant studies of physical activity (PA) can provide insight into the prevention of chronic disease. It is unclear, however, whether PA increases or decreases the longer migrants live in their host country. In the US, studies on immigrants' length of residence in the US and PA are inconclusive and many studies do not adequately consider the role of socioeconomic status (SES). Using California data, we examine relationships between immigrant generation and physical activity (PA) among Mexican, Chinese and Filipino adults, who represent the three largest immigrant groups in the US, and the extent to which the relationships are confounded by SES. Data from the 2000 US Census was linked with data on adults 18 years and older from the 2005 California Health Interview Survey. PA was measured in three different domains: leisure time (LTPA), non-leisure time (NLTPA) and any PA. Logistic regression was used to examine whether a wide range of SES factors, measured at the respondent and neighborhood levels, influenced the relationship between immigrant generation and PA in all domains and in different ethnic origin groups. Generation was significantly associated with LTPA among Mexican and Chinese adults and with NLTPA among all 3 ethnic origin groups; however the nature of the relationships varied. After adjusting for individual and neighborhood SES factors, a positive association between generation and LTPA remained among Mexican adults, and negative association between generation and NLTPA remained among Chinese and Filipino adults. These results underscore the importance of comparative studies of immigrant generation and PA and consideration of SES factors to identify pathways linking generation to PA. In the context of increasing rates of chronic disease, the study of transitions in PA among immigrants will continue to be critical to promoting the public health of diverse populations in countries such as the US.

Abstract
The Internet is a relatively new method of delivering strategies for health behavior change. The purpose of this study was to determine the feasibility of delivering a physical activity intervention by the Internet to improve outcomes in adults with the metabolic syndrome. Twenty-two participants (16 males; 6 females) were recruited from a cardiology clinic database, age range 32-66 years. Participants were randomly assigned to the Internet intervention (n = 12) or the usual care ( n = 10) group. The mean total dose, in terms of the time the intervention Web site was accessed was 2 hours over 6 weeks, which was greater than the time spent delivering usual care. Overall, participants' evaluations of the Internet intervention were positive. The costs of development and delivery of the Internet intervention were less than that of a consultation and follow-up in the cardiology clinic for this sample. The Internet intervention appears feasible for testing in a larger study.

Abstract
OBJECTIVE To examine the association between physical activity recorded by actigraphy during therapy sessions (therapy) with therapist-rated patient participation and self-reported future functional outcomes. We hypothesized those participants who were more active during rehabilitation would have higher participation scores and better functional outcomes after hip fracture compared with those who were less active. DESIGN Longitudinal study with a 3- and 6-month follow-up. SETTING Participants were recruited from skilled nursing facilities (SNFs) and inpatient rehabilitation facilities (IRFs). PARTICIPANTS Participants included 18 community-dwelling older adults admitted to SNFs or IRFs facilities after hip fracture. Participants were included if they were 60 years of age or older and ambulatory with or without assistance from a device or another person. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Physical activity was quantified during participants' rehabiliation by using the actigraph accelerometer worn consecutively over 5 days. The Pittsburgh Participation Rating Scale was used to quantify patient participation during their inpatient therapy sessions. Self-reported functional outcomes were measured by the Hip Fracture Functional Recovery Scale at baseline and 3 and 6 months after fracture. RESULTS Participants with higher actigraphy counts during rehabilitation were ranked by their therapists as having excellent participation compared with those who were less active. Participants who were more active reported better functional abilities at both the 3- and 6-month time points and achieved 78% and 91% recovery of self-reported prefracture function compared with those who were less active achieving 64% and 73% recovery. CONCLUSIONS Actigraphy provides an objective measure of physical activity exhibiting predictive validity for future functional outcomes and concurrent validity against patient participation in patients after hip fracture.

Abstract
Research into the accuracy of self-reported measures used to quantify physical inactivity has been limited. The purposes of the current report were to examine the reliability of a survey question assessing time spent watching television and to describe associations between television watching and physical activity and health risk factors. Data from this cross-sectional investigation were obtained from a study designed to evaluate a physical activity module for potential use in the 2001 Behavioral Risk Factor Surveillance System. Participants were 93 men and women (aged 45.9 (15.4) years) who answered the question pertaining to television watching during an initial visit and three follow-up visits to the study center. Intra-class correlation coefficients (ICCs) between administrations of the survey question were used to assess test-retest reliability. Spearman rank order correlation coefficients were used to examine the associations of television viewing with physical activity and health risk factors. The test-retest reliability of the television-watching question suggested moderate agreement (ICCs of 0.42 and 0.55 over a 3-week and 1-week period, respectively). After adjustment for age and sex, reported television-watching hours were positively associated with BMI (P = 0.0002), percentage fat (P = 0.0001), and light-intensity physical activity (P = 0.006) and negatively associated with cardiorespiratory fitness (P = 0.004) and moderate-intensity and hard-intensity physical activity (P = 0.03 and P = 0.003, respectively). Increased time spent in sedentary behaviors has been identified as a major modifiable risk factor in the development of chronic diseases and conditions. The single-item survey question evaluated in this study was shown to be a reliable measure of television watching and was associated with physical activity and health risk factor outcomes.

Abstract
We examined the associations between physical activity (PA), fitness and all-cause mortality and compared their contributions, taking smoking status into consideration. A retrospective cohort study of 18,775 men was carried out between May 1995 and December 2003. Fitness was measured by maximum oxygen uptake and regular PA was defined as at least three times a week, for more than 30 min of leisure time PA. During the mean 6.4 yr of follow-up, 547 deaths were recorded. The hazard ratio (HR) (95% confidence interval [CI]) of regular PA for all-cause mortality was 0.63 (0.52-0.76). The HRs (95% CIs) for men with middle and highest tertile levels of fitness were decreased by 0.58 (0.47-0.70) and 0.58 (0.45-0.75) in comparison to men with lowest one. The inverse association between fitness and mortality was significant among the men who did not engage in regular PA, but not among those who did (p for interaction=0.031). Smoking status did not influence on the associations between regular PA, fitness and mortality. Our result suggested that regular PA and fitness predicted mortality in men. The influence of fitness on mortality was pronounced in the men who did not engage in regular PA.

Abstract
BACKGROUND Accurate assessment is required to assess current and changing physical activity levels, and to evaluate the effectiveness of interventions designed to increase activity levels. This study systematically reviewed the literature to determine the extent of agreement between subjectively (self-report e.g. questionnaire, diary) and objectively (directly measured; e.g. accelerometry, doubly labeled water) assessed physical activity in adults. METHODS Eight electronic databases were searched to identify observational and experimental studies of adult populations. Searching identified 4,463 potential articles. Initial screening found that 293 examined the relationship between self-reported and directly measured physical activity and met the eligibility criteria. Data abstraction was completed for 187 articles, which described comparable data and/or comparisons, while 76 articles lacked comparable data or comparisons, and a further 30 did not meet the review's eligibility requirements. A risk of bias assessment was conducted for all articles from which data was abstracted. RESULTS Correlations between self-report and direct measures were generally low-to-moderate and ranged from -0.71 to 0.96. No clear pattern emerged for the mean differences between self-report and direct measures of physical activity. Trends differed by measure of physical activity employed, level of physical activity measured, and the gender of participants. Results of the risk of bias assessment indicated that 38% of the studies had lower quality scores. CONCLUSION The findings suggest that the measurement method may have a significant impact on the observed levels of physical activity. Self-report measures of physical activity were both higher and lower than directly measured levels of physical activity, which poses a problem for both reliance on self-report measures and for attempts to correct for self-report - direct measure differences. This review reveals the need for valid, accurate and reliable measures of physical activity in evaluating current and changing physical activity levels, physical activity interventions, and the relationships between physical activity and health outcomes.

Abstract
BACKGROUND While the benefits of physical activity are generally recognized, over half of adult Canadians are not active enough to receive those benefits. Physicians may influence patient activity through counselling; however, research is inconsistent regarding their effectiveness in doing so. Increasing patients' use of self-regulatory skills in managing their activity and additional telephone support are suggested as two means of improving physician counselling. When assessing the effectiveness of physician counselling, it may be important to measure both outcome and treatment adherence. We compared physician-directed activity counselling (modified PACE protocol) with a modified PACE protocol augmented with telephone-based counselling for patient support for both outcome and treatment adherence. METHODS Physicians counselled 90 patients using a modified PACE protocol that included self-regulatory skills. Physical activity was assessed by questionnaire at baseline (prior to counselling) and one month later. Participants were divided into two groups: counselling (modified PACE counselling) and enhanced counselling (modified PACE counselling plus telephone support). RESULTS The main outcome (mean energy expenditure) and secondary outcomes of treatment adherence (frequency, frequency of moderate activity, and duration) significantly increased over time (p < 0.05). No significant interactions between group and time were found. INTERPRETATION Our results support the effectiveness of physician counselling for activity that included the use of self-regulation skills. The effectiveness of telephone support over and above that of physician counselling was not supported. Our results demonstrate that assessing treatment adherence provides a means of discerning whether the counselling intervention was delivered as intended.

Abstract
OBJECTIVE To determine the accuracy of self-reported activity by community-dwelling, lower-limb amputees. DESIGN Descriptive study. SETTING A regional prosthetics outpatient service. PARTICIPANTS Seventy-seven unilateral lower-limb amputees at least 6 months after prosthetic rehabilitation. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Measured activity counts (in steps/min) and self-reported activity (rest, low, medium, high) in 15-minute intervals over 1 week were recorded for each participant. RESULTS Participants averaged 3063+/-1893 steps per day. Strong agreement (gamma> or =0.7) between self-reported and measured activity was found for only 34% of participants between the hours of 9:00 am to 9:00 pm. The measured and self-reported proportion of time spent in various states of activity also showed poor agreement (rest, r=.41; low level activity, r=.39; medium level, r=.26; high level, r=.40). There was no bias toward either over- or under-reporting. CONCLUSIONS The majority of participants were unable to accurately self-report their activity levels (sleep excluded) as compared with measured activity levels. This may have important implications for prescribing appropriate prosthetics and for clinicians who provide patients with advice on promoting health.

Abstract
Although some evidence suggests that exercise may improve mental health status, information regarding the intensity and duration of exercise is incomplete. The purpose of this study was to elucidate the association between physical activities in both leisure time and commuting to work and mental health. A questionnaire survey was conducted at three municipal offices in Japan. A total of 670 men and women completed the questionnaire. Mental health status was assessed by the 28-item General Health Questionnaire (GHQ). Respondents were asked about weekly hours of leisure-time exercise for four levels of exercise, and the volume of exercise was assessed using a metabolic equivalent task index. Information about commuting to work on foot or by bicycle was also obtained. The mean GHQ scores were calculated according to physical activity levels using analysis of covariance with adjustment of potential confounders including job stress. In men, the GHQ score decreased steadily with increasing levels of leisure-time exercise, and an inverse association was evident even for mild intensity exercise. Moreover, the GHQ score decreased according to increasing duration of time on commuting to work by either walking or cycling in men, but not in women. These relations did not materially change after adjustment for potential confounding factors. In women, there was no significant association between any of the indices of physical activity. In conclusion, leisure-time exercise and walking or cycling during commuting to work may be associated with better mental health in men.

Abstract
Despite the numerous benefits of physical activity for patients with diabetes, most healthcare providers in busy clinical settings rarely find time to counsel their patients about it. A Web-based program for healthcare providers can be used as an effective counseling tool, when strategies are outlined for specific stages of readiness for physical activity. Seventy-three adults with type 2 diabetes were randomly assigned to Web-based intervention, printed-material intervention, or usual care. After 12 weeks, the effects of the interventions on physical activity, fasting blood sugar, and glycosylated hemoglobin were evaluated. Both Web-based and printed material intervention, compared with usual care, were effective in increasing physical activity (P < .001) and decreasing fasting blood sugar (P<.01) and glycosylated hemoglobin (P < .01). Post hoc analysis for change scores indicated significant differences between Web-based intervention and usual care and between printed material intervention and usual care, but not between web-based and printed material intervention. The findings of this study support the value of Web-based and printed material interventions in healthcare counseling. With increasing Web access, the effectiveness of Web-based programs offered directly to patients needs to be tested.

Abstract
Most studies to date support a protective role of physical activity in reducing stroke risk. However, they were not able to take into account combined work and leisure activity. We prospectively followed up 22,602 men and women aged 40-79 years, who had no history of stroke and myocardial infarction at baseline, participating in the European Prospective Investigation into Cancer-Norfolk. Participants were categorized into four levels of physical activity based on a validated self-reported questionnaire, which assesses combined work and leisure activities, at baseline during the period from 1993 to 1997. Stroke incidence was ascertained by death certificate and hospital record linkage data up to 2004, average 8.6 years of follow-up. We used the Cox proportional hazards model. There were 361 incident strokes during follow-up (total person years = 195,092). After adjusting for age, sex, systolic blood pressure, body mass index, cholesterol, history of diabetes and smoking, men and women who were physically active were less likely to have a stroke (relative risk = 0.70, 95% CI: 0.49-0.99, p = 0.024) compared to those who were inactive. This highlights the fact that efforts to increase physical activity in both the work place and in leisure time should be encouraged.

Abstract
PURPOSE The purpose of these analyses was to describe the levels and types of activity in relationship to current marital status among older adults and determine if the physical activity level of the husband was related to the physical activity level of his wife. METHODS Participants included 3075 well-functioning white and black men and women aged 70-79 yr with further examination of 345 spousal pairs. Marital status was self-reported and participants were grouped as married versus not married. Based on responses to a leisure-time questionnaire, total physical activity was calculated and participants were classified as low or high active. Descriptive statistics were used to describe level and proportions of type of activity by marital status. Logistic regression was used to determine if marital status was an important determinant of physical activity participation. Regression models were adjusted for demographics, body mass index (BMI), and chronic disease conditions. RESULTS When compared with their single counterparts, married men reported higher median levels of exercise participation (P = 0.008) and married women reported higher levels of total (P < 0.0001) and nonexercise activity (P < 0.0001) with a trend toward higher exercise participation (P = 0.05). In spousal pairs, compared with men in the low active group, highly active men were almost three times as likely (OR = 2.97; 95% CI = 1.73, 5.10) to have a similarly active spouse. The model only modestly attenuated when adjusted for age, BMI, and health status of the husband [OR = 2.49 (1.41, 4.42)]. CONCLUSIONS Marital status and spousal physical activity (PA) levels are important determinants for PA participation among older adults.
