ABSTRACTBackground: Physical exercise has a lot of benefit for health. However, the effect of cognitive function such as concentration in teenagers has yet been known.Aims: The objective of this study was to analyze the effect of a single bout or acute moderate intensity physical exercise on the level of concentration in teenagers.Methods: The subjects of this study were 32 16-18 years old teenagers, divided into two groups, control (C) and exercise (E) groups. Each group consisted of 8 boys and 8 girls. The E group did a single bout of moderate exercise using ergocycle. Physical exercise duration was 15 minutes, preceded by 5 minutes of warming up and then followed by 5 minutes of cooling down exercise. The concentration level was measured using the response period to sound stimulation (in second), measured with reaction time machine pre- and post-treatment. Faster response showed better concentration level and vice versa. Data were analyzed using paired T test, Wilcoxon Signed Ranks Test, independent T test, and Mann-Whitney test. The significance level was 5%.Result: There were significant differences of concentration level between pre- and post-exercise in E group (p= 0.004) and post-exercise concentration level between groups (p = 0.01). Exercise group had faster reaction time than C group (0.555±0.2 vs. 0.793±0.3, respectively).Conclusion: A single bout of moderate intensity exercise can improve the cognitive function showed by increased concentration level in teenagers.

Abstract Background: This study was designed to determine the effects of ascorbic acid (AA) supplementation on immune status following a single bout of exercise. Materials/Methods: In a crossover design with a 1 week wash-out period, 20 healthy sedentary women performed 30 minutes moderate-intensity cycling with (1,000AA) or without (0AA) ingesting 1,000 mg of AA daily for 1 week. Blood samples were taken immediately before, immediately after and 24 hours post-exercise to determine the oxidative stress markers, hematological parameters, immunophenotyping of peripheral blood lymphocytes and neutrophil phagocytic function with Candida albicans. Results: Moderate-intensity exercise in subjects ranged in age from 21 to 23 years, showed no significant changes in oxidative stress markers in both cohorts. Plasma total creatine kinase was increased immediately after exercise and returned to baseline at 24 h post-exercise in both cohorts. Subjects ingesting 1,000 mg AA demonstrated significant higher level of plasma AA at pre-exercise and post-exercise as compared with the same time point in 0AA group. White blood cell and absolute neutrophil counts were increased immediately after exercise and returned to baseline at 24 h post-exercise in both cohorts. Exercise resulted in increased lymphocyte count, CD4+ T cells, CD8+ T cells, CD45+/CD3-/CD4- cells, CD45+/CD3+/CD4- cells, CD45+/CD3-/CD8- cells, CD45+/CD3+/CD8- cells and CD45+/CD3-/CD8+ cells immediately after exercise (p<0.05) with a return to baseline at 24 hours in 0AA group. AA supplement mitigated effects of exercise on CD4+ T cells and CD45+/CD3-/CD8- cells. No significant change in neutrophil phagocytic function were observed when incubated with low or high concentrations of C. albicans in both cohorts. Conclusion: A single bout of exercise induced muscle damage and transient changes in neutrophil count as well as lymphocyte subpopulations in sedentary women. Ascorbic supplementation does not show beneficial effect to the moderate-intensity exercise.

Adaptation To Exercise

Abstract Exercise counteracts obesity effects, but information on how early-life obesity may affect long-term adaptation to exercise is lacking. This study investigates the impact of early-life postnatal overfeeding (PO) on animals’ adaptation to exercise. Only male Wistar rats were used. On postnatal day (PN) 30, rats from control (NL-9 pups) or PO (SL-3 pups) litters were separated into four groups: NL-sedentary (NL-Se), NL-exercised (NL-Ex), SL-sedentary (SL-Se), and SL-exercised (SL-Ex). Exercised groups performed moderate-intensity exercise, running on a treadmill, from PN30 to PN90. Further experiments were carried out between PN90 and PN92. PO promoted obesity in SL versus NL rats (P < 0.05). Exercise reduced body weight (P < 0.001), body fat (P < 0.01), and improved glucose homeostasis in SL-Ex versus SL-Se. SL-Ex presented lower VO2max (P < 0.01) and higher post-exercise LDH (P < 0.05) compared to NL-Ex rats. Although moderate exercise counteracted obesity in SL rats, early-life overnutrition restricts fitness gains in adulthood, indicating that early obesity may impair animals’ adaptation to exercise.

Background: The death of β cells Langerhans islets in Diabetes Mellitus (DM) can cause  loss of Langerhans islet function and worsen the progression of DM. Physical exercise plays a major part in DM treatment.Aim: to observe the effect of moderate intensity exercise to β (beta) cell numbers and Langerhans islets area size in Streptozotocin (STZ) induced diabetes in rats.Methods: Thirty adult male Wistar rats (Rattusnorvegicus) divided into 3, Group 1 as the control, Group 2 received 35 mg/kg streptozotocin induction treatment, Group 3 received 35 mg/kg streptozotocin induction and physical exercise, swimming, with moderate intensity 70% from the swimming maximal ability, 9% of body weight load, 4 times a week for 4 weeks. Datas collected were in the form of histopathology slide of pancreatic tissue after receiving treatment for 28 days.Results: There are significant differences of β-cell pancreas number between group K1 and K2 (p<0,001), group K2 and to K3 (p<0,001). No significant difference between group K1 and K3 (p=0,102). The Langerhans islets area sizes of pancreas tissue between group K1, K2, and K3 are significantly different (p<0,001).Conclusion: This study shows moderate-intensity physical exercise can increase the number of β cell and average area size of Langerhans islets. The effect of physical exercise depends on the intensity of exercise and the capacity of pancreatic function left of the diabetic.

Background: Altered autonomic balance has been noted in Irritable bowel syndrome Regular physical exercise may cause restoration of autonomic balance in health and disease.Objective: To assess the effect of brisk walking on the autonomic balance by analysis of heart rate variability in patients with Irritable bowel syndrome (IBS).Methods: This prospective study was conducted in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU) in 2013.Seventy seven male IBS patients aged 20-50 years, were enrolled from Gastroenterology OPD, BSMMU, Dhaka. Twenty eight healthy sedentary male with similar age were control. HRV measures were recorded once prior to exercise and then after 3 months of brisk walking. For assessing autonomic balance, LF/HF ratio and Max/Min RR was evaluated by Polyrite D machine and software. ANOVA, Independent sample t-test and paired t-test were used for statistical analysis.Results: The pre-exercise mean values of LF/HF ratio were significantly higher (p<0.001) in all IBS patients compared to those of control. The post exercise LF/HF ratio were significantly lower (p<0.05) in all IBS patients compared to their pre-exercise values.Conclusion: This study concluded that the sympathovagal balance was towards sympathetic predominance in IBS and regular moderate physical exercise may shift the balance towards parasympathetic predominance in them.Bangladesh Soc Physiol. 2015, June; 10(1): 6-10
