Comparisons of hydration status of young Indian male athletes of different sports and its impact on isometric strength and aerobic power
摘要
The present study aimed to investigate the effect of sports-specific activities on hydration status and different physiological profiles and their relationship in young Indian male sportspersons in different sports activities.
MethodsA total 412 young male athletes from four sports disciplines viz. football (FB; n = 93), field hockey (HK; n = 106), table tennis (TT; n = 68), and badminton (BDT; n = 52) of 13–21 years were evaluated at the end of their preparatory phase. In all, 93 age-matched sedentary subjects served as the control group (CTRL). Whole body bio-electrical impedance analysis (BIA) was performed to calculate body fat%, fat-free mass (FFM), glycogen mass, and body water of different compartments. Maximum isometric hand grip and back strength, and 20 m multistage shuttle run test to measure VO2 max were also conducted.
ResultsBody fat%, FFM and glycogen mass shows significant differences among the different groups of the present study (p < 0.01). Among the different sports discipline groups TT and BDT players possess higher body fat percentages. On the other hand, the mean value of FFM and glycogen mass is found to be higher in hockey and badminton players. It is also noted that the mean values of back strength and VO2max of hockey players are significantly higher as compared to different groups (p < 0.01). Body water of different compartments including total body water (TBW), extracellular water (ECW), and intracellular water (ICW) is significantly different among the different groups of the present study. Relative strength and VO2 max are positively and significantly (p < 0.01) correlated with ICW and relative ICW. It is observed that ~7.7% less ICW content in TT players than in HK in the present study, may be the cause of ~17% lower grip strength, ~14% lower back strength, ~22% lower aerobic power, despite of being similar age and general physical characteristics.
ConclusionDue to different sports activities TBW varies and is positively correlated with strength and aerobic power, while ICW by age caused little or no positive impact on maturity and was the only component associated significantly with strength and aerobic power despite different age categories and sports disciplines. Specifically, to establish the regulating effect of cellular hydration and interconnected fluid compartments on whole-body physiology and metabolism, further research is required.
