To investigate the predictive ability of nutritional status, sleep quality and lean body mass with physical performance parameters in National level Kho Kho players
Fifty national level Kho Kho players (age: 23.1±3.74 years, BMI: 21.4±1.87 kg/m2) participated in this study. Nutritional status (carbohydrate, protein and fat intake, serum calcium and serum vitamin D3 and hydration status), sleep quality and lean body mass of all the participants was evaluated. Dependent variables which demarcated physical performance such as speed, power and agility were also evaluated with the help of validated field tests. Appropriate statistical tests were employed in order to test the predictive ability of independent variables for physical performance parameters.
Univariate analysis showed that hydration and protein intake were significant predictors of speed performance. Sleep quality was found to be a significant predictor of agility performance while lean body mass came out to be a predictor of power performance. In co-variate adjusted multivariate analysis, only hydration status of the athletes came out to be a significant independent predictor of speed performance [0.99 (0.99, 1.00); p=0.003] in Kho Kho players.
Findings of the present study suggest that sleep quality of athletes was associated with agility performance while lean body mass was associated with power performance and protein intake was found to be associated with sprint performance. Most important finding of this study suggested that hydration status is a significant independent predictor of sprint performance in national level Kho Kho players.
