JOURNAL OF SPORT AND HEALTH SCIENCE 2024; 13:339-352. [PMID: 37832643 PMCID: PMC11116964 DOI: 10.1016/j.jshs.2023.10.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/01/2023] [Revised: 08/17/2023] [Accepted: 09/08/2023] [Indexed: 10/15/2023]
Abstract
BACKGROUND B cells represent a crucial component of adaptive immunity that ensures long-term protection from infection by generating pathogen-specific immunoglobulins. Exercise alters B cell counts and immunoglobulin levels, but evidence-based conclusions on potential benefits for adaptive immunity are lacking. This systematic review assessed current literatures on the impact of acute exercise and exercise training on B cells, immunoglobulins, and markers of secretory immunity in human biofluids. METHODS According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, MEDLINE, Web of Science, and Embase were searched on March 8, 2023. Non-randomized controlled trials and crossover trials investigating the impact of acute exercise or exercise training on B cell counts and proportions, immunoglobulin levels, salivary flow rate, or secretory immunoglobulin A secretion rate were included. Quality and reporting of exercise training studies were assessed using the Tool for the Assessment of Study Quality and reporting in Exercise. Study characteristics, outcome measures, and statistically significant changes were summarized tabularly. RESULTS Of the 67 eligible studies, 22 applied acute exercise and 45 applied exercise training. All included outcomes revealed significant alterations over time in acute exercise and exercise training context, but only a few investigations showed significant differences compared to control conditions. Secretory and plasma immunoglobulin A levels were most consistently increased in response to exercise training. CONCLUSION B cell-related outcomes are altered by acute exercise and exercise training, but evidence-based conclusions cannot be drawn with high confidence due to the large heterogeneity in populations and exercise modalities. Well-designed trials with large sample sizes are needed to clarify how exercise shapes B cell-related immunity.

Abstract
This chapter presents the epidemiologic evidence on the association between physical activity and hematologic cancers and related hypothesized biologic mechanisms. Some preliminary indications of a protective role for physical activity for non-Hodgkin's lymphoma, leukemia, multiple myeloma, and Hodgkin's lymphoma exist, but the level of epidemiologic evidence is still insufficient to make any definitive conclusions regarding the nature of these associations. Several plausible biologic mechanisms underlying the possible associations between physical activity and hematologic cancers have been proposed, including enhancement of immune function, reduction in obesity, improvement of antioxidant defense systems, impact on metabolic hormones, and anti-inflammatory effects. Future studies should improve the estimation of physical activity by using more reliable, valid, and comprehensive measurement tools, assessing all components of physical activity (type, intensity, and time period), and conducting intervention studies to evaluate the effect of physical activity on various biomarkers of cancer in order to provide further insight into plausible biologic mechanisms underlying the possible association between physical activity and hematologic cancers.

Abstract
Brief high intensity exercise induces peripheral leukocytosis possibly leading to a higher incidence of allergic symptoms in athletes undergoing excessive training. We studied the exercise-induced alternation of circulating Tregs and FoxP3+ Tregs due to acute intense swim exercise in elite swimmers (n = 22, 12 males, age = 15.4 yrs). Twelve had prior or current rhinitis or asthma and 10 had no current or prior allergy or asthma. Circulating Tregs increased significantly (p < .001) following exercise (pre = 133 +/- 11.2, post = 196 +/- 17.6) as did FoxP3+ cells (pre = 44, post = 64 cells/microl). Increases in Tregs and FoxP3+ Tregs occurred to the same extent in both groups of adolescent swimmers.

Abstract
A intensidade, volume, modalidade de exercício, assim como o nível de aptidão e fatores nutricionais podem alterar a reposta imunológica. O objetivo deste estudo foi avaliar o efeito da suplementação crônica de farelo de aveia (fonte de fibras solúveis) sobre as células do sistema imunológico em ratos treinados, frente a um teste de exaustão. Foram utilizados ratos Wistar, ± dois meses, peso ± 200g, divididos em três grupos (n = 9, cada um): 1) controle sedentário (C); 2) treinado oito semanas submetido ao teste de exaustão (EX); e 3) treinado oito semanas submetido ao teste de exaustão com suplementação de 30% de farelo de aveia (EXA). O treinamento consistiu de 60 minutos de natação diários, cinco dias por semana durante oito semanas. As análises realizadas foram: contagem total de leucócitos, linfócitos dos linfonodos mesentéricos, macrófagos peritoneais e capacidade fagocitária de macrófagos peritoneais. Aplicou-se o teste estatístico ANOVA two way, seguido do post hoc de Tukey com p < 0,05. O grupo EX apresentou leucocitose quando comparado com o controle, o que não ocorreu no grupo EXA, porém, na comparação entre os grupos exercitados EXA, mostrou menor leucocitose em relação a EX. Não houve alteração significativa nos linfócitos teciduais em nenhum dos grupos exercitados. Tanto o número de macrófagos peritoneais como a capacidade fagocitária desta célula foram maiores nos grupos exercitados. Porém, no grupo suplementado a capacidade fagocitária foi maior em relação ao grupo exaustão sem farelo de aveia. A suplementação de fibras solúveis demonstrou resultados benéficos com relação às alterações imunológicas induzidas pelo exercício extenuante, além de aumentar a capacidade fagocitária de macrófagos peritoniais em ratos treinados durante oito semanas submetidos ao teste de exaustão.

Abstract
In this study, we assessed the effects of a 4 week basic military physical training programme for male recruits of the Hellenic Air Force on the number and distribution of circulating immune cells and adrenergic and adrenocortical hormonal responses. One group of recruits (exercised, n = 48) participated in moderate intermittent physical exercise, whereas a second group (non-exercised controls, n = 9) performed only light work in the barracks. Both groups participated in the same non-physical, classroom-type training and testing. Military training by the exercised group resulted in significant increases in CD4+ T-lymphocytes, renal cortisol excretion and the urinary noradrenaline/adrenaline ratio, together with reductions in neutrophils and the neutrophil/lymphocyte ratio. In the exercised group, the urinary noradrenaline/adrenaline ratio correlated positively with the training-induced changes in CD4+ T-lymphocytes and negatively with changes in the neutrophil/lymphocyte ratio. No significant relationship was found between training-induced increases in cortisol excretion and any of the peripheral blood cell alterations. Our results indicate that 4 weeks of military training consisting of intermittent moderate exercise resulted in a significant increase in CD4+ T-lymphocytes and reduction in neutrophils. These changes were probably driven by alterations in hormonal status, including the significant impact of sympathetic nervous system activation.

Abstract
The aim of this study was to investigate the influence of low-dose bovine colostrum protein concentrate (CPC) supplementation on selected immune variables in cyclists. Twenty-nine highly trained male road cyclists completed an initial 40-km time trial (TT(40)) and were then randomly assigned to either a supplement (n = 14, 10 g bovine CPC/day) or placebo group (n = 15, 10 g whey protein concentrate/day). After 5 wk of supplementation, the cyclists completed a second TT(40). They then completed 5 consecutive days of high-intensity training (HIT) that included a TT(40), followed by a final TT(40) in the following week. Venous blood and saliva samples were collected immediately before and after each TT(40), and upper respiratory illness symptoms were recorded over the experimental period. Compared with the placebo group, bovine CPC supplementation significantly increased preexercise serum soluble TNF receptor 1 during the HIT period (bovine CPC = 882 +/- 233 pg/ml, placebo = 468 +/- 139 pg/ml; P = 0.039). Supplementation also suppressed the postexercise decrease in cytotoxic/suppressor T cells during the HIT period (bovine CPC = -1.0 +/- 2.7%, placebo = -9.2 +/- 2.8%; P = 0.017) and during the following week (bovine CPC = 1.4 +/- 2.9%, placebo = -8.2 +/- 2.8%; P = 0.004). Bovine CPC supplementation prevented a postexercise decrease in serum IgG(2) concentration at the end of the HIT period (bovine CPC = 4.8 +/- 6.8%, P = 0.88; placebo = -9.7 +/- 6.9%, P = 0.013). There was a trend toward reduced incidence of upper respiratory illness symptoms in the bovine CPC group (P = 0.055). In summary, low-dose bovine CPC supplementation modulates immune parameters during normal training and after an acute period of intense exercise, which may have contributed to the trend toward reduced upper respiratory illness in the bovine CPC group.

Abstract
The authors conducted a population-based case-control study of 1,030 cases with histologically confirmed, incident non-Hodgkin's lymphoma (NHL) and 3,106 controls to assess the impact of recreational physical activity, obesity, and energy intake on NHL risk in Canada from 1994 to 1997. Compared with those for subjects in the lowest quartiles of total recreational physical activity, multivariable-adjusted odds ratios for subjects in the highest quartile were 0.79 (95% confidence interval (CI): 0.59, 1.05) for men and 0.59 (95% CI: 0.42, 0.81) for women. Obesity (body mass index > or = 30 kg/m2) was associated with odds ratios of 1.59 (95% CI: 1.18, 2.12) for men and 1.36 (95% CI: 1.00, 1.84) for women. For men and women with a lifetime maximum body mass index of > or = 30 kg/m2, respective odds ratios were 1.55 (95% CI: 1.16, 2.06) and 1.10 (95% CI: 0.83, 1.46). For men and women in the highest quartiles of calorie intake, respective odds ratios were 1.95 (95% CI: 1.45, 2.62) and 1.13 (95% CI: 0.84, 1.52). Some differences were found between histologic subtypes of NHL for these associations. This study suggests that recreational physical activity decreases NHL risk, while obesity and excess calorie intake increase it. More studies are needed to confirm these results, especially the differences between histologic subtypes.

Abstract
Exercise is the strongest stress to which the body is ever exposed. The body responds to this stress through a set of physiological changes in its metabolic, hormonal and immunological systems. In this study, responses of the immune system to the long-term aerobic and anaerobic exercises have been investigated. Twenty-four sedentary male university students and officers participated in this study. Subjects were divided into two groups, each consisting of twelve people. Group-1 (age: 25.67 +/- 3.79 years, height: 174.83 +/- 5.15 cm, body mass: 72.17 +/- 8.05 kg) and Group-2 (age: 24.83 +/- 2.89 years, height: 175.3 +/- 6.68 cm, body mass: 70.67 +/- 6.15 kg). After physical examinations of the two groups, resting ECG, respiratory function tests and metabolic tests with the use of the breath by breath method were completed, and anerobic heart rates at the threshold level were determined. The first group was subjected to exercise using Monark ergometry cycles at a heart rate 10% below the threshold level for 8 weeks, 3 days a week, 30 min a day. The second group exercised at a heart rate 10% above the threshold level for 8 weeks, 3 days a week, 20 min a day. Heart rates were checked with the Polar Test during exercises. Pre-exercise (Ep) venous blood samples were taken from each group before their 1st and 24th exercises. Hb (gr), Hct (%), erythrocyte (x10(6)/microl), leukocyte (x10(6)/microl), leukocyte subpopulations (neutrophil, lymphocyte, monocyte, eosinophil, basophil %) and thrombocyte (x10(6)/microl) values were determined. CD3, CD4, CD8, CD19 and CD56 values were determined by Flow Cytometry method using monoclonal antibodies. The chronic effects of exercise were examined through a comparison of Ep blood samples at the 1st exercise with Ep blood samples at the 24th exercise. While the increase in the total leukocyte number was significant (p<0.05) in the first group, increase in the second group was found to be non-significant. When percentiles of leukocyte subpopulations were taken into consideration, changes in the first and second group were found to be non-significant. When lymphocyte subgroups were examined; in the first group a decrease in CD3 and CD4 percentiles to 7% and 12%, respectively (p<0.05) and a 65% increase (p<0.01) in the CD56 value were observed. In the second group a decrease in CD3 and CD4 percentiles to 13% and 17%, respectively (p<0.05) and a 73% increase (p<0.01) in the CD56 value were observed. The Sample-t Test and The Wilcoxon Test were used for statistical analysis.

Abstract
Meta-analysis techniques have been used to accumulate data from 94 studies describing the natural killer (NK) cell response of some 900 volunteers to acute and chronic exercise. NK cell numbers have been indicated in terms of CD3-CD16+CD56+, CD16+ or CD56+ phenotypes, and cytolytic activity has been expressed per 10,000 peripheral blood mononuclear cells or in terms of lytic units. Acute exercise has been categorised as sustained moderate (50 to 65% of aerobic power), sustained vigorous (>75% of aerobic power), brief maximal or 'supramaximal', prolonged, eccentric or resistance, and repeated exercise. In general, there was a marked increase in NK cell count at the end of exercise, probably attributable to a catecholamine-mediated demargination of cells. Following exercise, cell counts dropped to less than half of normal levels for a couple of hours but, except in unusual circumstances (e.g. prolonged, intense and stressful exercise), normal resting values are restored within 24 hours. If activity is both prolonged and vigorous, the decrease in NK cell counts and cytolytic activity may begin during the exercise session. Although the usual depression of NK cell count seems too brief to have major practical importance for health, there could be a cumulative adverse effect on immunosurveillance and health experience in athletes who induce such changes several times per week. There is a weak suggestion of an offsetting increase in resting NK cell counts and cytolytic action in trained individuals, and this merits further exploration in studies where effects of recent training sessions are carefully controlled.

Abstract
OBJECTIVE This study examined relationships of gender, psychosocial stress/distress (caregiving, hassles, depressed mood), and the relative percentage and absolute cell counts of CD4 and CD8 cells in two samples of older adults (mean age = 69.4)--spouse caregivers of persons with Alzheimer's disease (N = 78) and age- and gender-matched spouses of nondemented controls (N = 72). METHODS Counts and percentages of CD4 and CD8 cells and psychosocial variables were assessed twice (Time 1, Time 2) over a 15- to 18-month period. Several covariates were examined in the analyses, including body mass index (BMI), medication use, alcohol use, exercise, and illness history. RESULTS Caregiver men had fewer CD4 cell counts at Times 1 and 2 than did control men (p < .05). At Times 1 and 2, both CD8 cell counts and percentages were positively associated with hassles in men (p < .05), but not in women. Although interactions of hassles and gender were present for CD8 percentages at both times, interactions and main effects were not present for CD4 percentages at either time. When the ratio of CD4 to CD8 levels was analyzed, hassles by gender interactions were present at both Times 1 and 2-hassles were negatively associated with the CD4/CD8 ratio in men (p < .05), but unrelated in women. From Time 1 to Time 2, change analyses showed that increases in hassles scores were associated with decreases in CD4 counts (p < .05), whereas increases in Hamilton Depression Scores were related to increases in both CD8 counts and percentages (p < .05). CONCLUSION Caregiver status, hassles, and depressed mood had cross-sectional and/or longitudinal associations with CD4 and CD8 counts, but such relationships occurred primarily in men. Moreover, absolute cell counts were more related to psychosocial factors than were percentages.
