Abstract

Background: Excessive physical exercises (overtraining) can increase the production of reactive oxygen species (ROS). One of the indicators of overtraining syndrome is a decrease in insulin-like growth factor binding protein 3 (IGFBP-3). Administration of Hibiscus sabdariffa Linn., a powerful antioxidant, is expected to boost endogenous antioxidants, and thus prevents overtraining. The aim of this study is to determine the effect of H. sabdariffa on IGFBP-3 levels in rats under ”overtraining physical excersice”.Methods: This experimental study was conducted on 30 male rats (Rattus norvegicus 200-250 grams), randomly allocated into 5 groups: 1) control group (C); 2) control with H. sabdariffa (C-Hib); 3) mild aerobic exercise (A-Ex); 4) overtraining exercise (OT); 5) overtraining exercise with H. Sabdariffa (OT-Hib). H. sabdariffa (400 mg/kg/d, 11 weeks) were administered orally via syringe cannula. IGFBP-3 was measured by using ELISA (Cusa bio kit) and data were analyzed with ANOVA test.Results: Plasma level of IGFBP-3 in the C and OT groups were 17.4 ± 10 mIU/L, the lowest in OT groups (10.7 ± 9.9 mIU/L) and the OT-Hib group had the highest level (31.5 ± 6.2 mIU/L). There was significant difference of the level IGFBP-3 in OT groups with A-Ex groups (10.7 ± 9.9 vs 23.5 ± 9.7 mIU/L; p < 0,05). The significant difference was also observed in the level of IGFBP 3 between C groups and the OT-Hib groups (17.4 ± 10 vs 31.5 ± 6.2; p < 0.05).Conclusion: Administration of H. sabdariffa can prevent the decrease of IGFBP-3 levels in overtraining rats, indicating its role in preventing overtraining syndrome.

Abstract

Background: The increasing number of circulating CD31+ endothelial progenitor cells is one of the important factors for maintaining vascular homeostasis. Exercise will effectively increase the number of circulating CD31+ endothelial progenitor cells. This study aims to determine the effect of moderate-intensity acute aerobic exercise duration on the percentage of circulating CD31+ cells in untrained healthy young adult subjects.Methods: This study was an experimental study. Untrained healthy volunteers (n=20) performed ergocycle at moderate-intensity (64–74% maximum heart rate) for 10 minutes or 30 minutes. Immediately before and 10 minutes after exercise, venous blood samples were drawn. The percentage of CD31+ cells in peripheral blood was analyzed using flow cytometry. Data was statistically analyzed using student t-test.Results: There were no significant differences in the mean percentage of circulating CD31+ cells before and after exercise for 10 minutes and 30 minutes (p>0.05). However, there was a different trend in the percentage of circulating CD31+ cells after exercise for 10 minutes and 30 minutes. In the 10 minutes duration, 50% of subjects showed increase. Whereas in the 30 minutes duration, 80% of subjects showed increase.Conclusion: The percentage of circulating CD31+ cells before and after exercise for 10 minutes was not different compared to 30 minutes. However, data analysis shows that majority of subjects (80%) had increased in the percentage of circulating CD31+ cells after 30 minutes exercise.

Abstract

BackgroundCognitive impairment and dementia are some of the major health concerns in the aging population. Many studies showed positive effects of physical exercise in delaying or preventing these conditions. Brain Gym ® exercises is a structured aerobic exercise involving head, eyes and crossing movements of the extremities in order to stimulate both brain hemispheres. This study was conducted to evaluate the effect of Brain Gym ® exercises sessions on cognitive function and plasma brain-derived neurotrophic factor (BDNF) in the elderly.MethodsA non-blinded randomized controlled study involving 64 healthy women aged >60 years who were randomized into Brain Gym ® exercises treatment group (n=32) and control group (n=32). Treatment group joined 60 minutes of brain gym exercises sessions twice a week for 12 weeks. The measured outcomes were cognitive function (assessed by mini-mental state examination [MMSE] questionnaire) and plasma BDNF levels. The outcomes were measured at base-line and after the intervention. An independent t-test was used to analyze the data.ResultsThe BDNF levels were increased in both groups after 12 weeks, and there was a significant difference between treatment group (41.26 ± 6,82 ng/mL) and control group (37.10 ± 8.11 ng/mL)(p=0.040). However, the MMSE score was not significantly different between the two groups (p=0.200).ConclusionBrain Gym ® exercises sessions significantly increase plasma BDNF level in the elderly population. In practical terms, we may suggest evaluation of the effects of Brain Gym ® exercises as a strategy in the treatment of disorders associated with central degenerative changes.
