Abstract:
The aim of this study was to compare the effect of consuming various fluid supplements while playing tennis on different playing surfaces on selected physiological and biochemical variables during simulated match at high temperature < 34 °C. Ten University level male tennis players, underwent eight treatment trials against the ball machine for 90 minutes, which had predetermined set protocol on Clay Surface (CS) and Hard Surface (HS); and consumed 1800 ml of different fluid supplements in each trial, namely Plain Water (PW), High Carbohydrate Drink (H-CHO), High Electrolyte Drink (H-ED) and Carbohydrate-Electrolyte Drink (CHO-E) in counterbalanced way. Two way repeated measures ANOVA were employed. It was concluded that CHO-E is the best drink on HS whereas on CS, CHO-E and H-ED are considered as best drink followed by H-CHO and PW respectively. This study shows that playing tennis on HS brings more physiological and biochemical changes than the CS at high temperature.
