Discussion The objective of this study was to evaluate the effects of a nutritional strategy on the physical performance of competitive tennis players. This strategy consisted of taking a pre-match drink, a match-drink and a post-match drink during every match of a simulated tennis tournament. Based on data in the literature, showing that a prolonged tennis

match could induce muscle fatigue [20,21], our first hypothesis was that repeated tennis matches would induce a decrease in physical performance even after a few hours of recovery compared to the resting condition. Since some studies have buy SIS3 also demonstrated that carbohydrate supplements during prolonged tennis matches delays the onset of fatigue [4,5,8–10], our second hypothesis was that drinking sports beverages before, during and after each tennis match would limit the decrease in physical performance compared to conditions where the only fluid intake was water. The main results show that playing three simulated tennis matches in a thirty-six-hour period did not significantly decrease

any of the physical performance measures 3 h after the last match. Various studies have shown that prolonged tennis playing in competitions leads to the development of muscle fatigue that may impair skilled performance on the court [3–6]. However, all of these studies conducted performance tests during or immediately after the match. Given the characteristics of tennis tournaments, i.e. several matches in a limited time-frame interspersed with

short recovery periods, it is important check details to consider whether these consecutive matches would finally result in decreased physical performance and whether ingesting sports drinks before, during and after each match would Chlormezanone limit fatigue, facilitate recovery and so favor improved performance in subsequent matches. Considering that nutritional strategies can have an important influence on the capacity to recover [14,22], notably influencing muscle and hepatic glycogen stores [23], we have been careful in this study to precisely control the amount and type of nutrients ingested during the meals taken by the players in the different conditions Sotrastaurin ic50 studied. Thus the breakfasts, lunches and dinners eaten on study days were standardized and identical for each of the conditions. The results of our study show that after playing three 2-hour matches within thirty-six hours, only 3 hours of passive recovery (including the ingestion of a standardized lunch) was sufficient to observe no significant decrease in physical performance parameters, compared to the rest condition. The only significant difference in physical performance was the increase in RMS values during the 90-s sustained isometric contraction at 25% MVC for the lateral head of the triceps brachii in the PLA condition compared to the CON condition.
