Ingestion of Beta-alanine Effects in Well-trained Tennis Players

Beta-alanine is considered as ergogenic aids with good to strong evidence for improving sports performance in specific sports context scenarios. However, most of the studies has been realized in endurance, with limited evidence in intermittent sports, especially in racket sports. Thus, the aim of this study was to explore the effects of 4-weeks ingestion of beta-alanine on neuromuscular performance in well-trained tennis players.

About this study

Fourteen tennis players (23.3 ±3.7 years) between 50-250 national tennis ranking participated in this study. Participants were randomly divided into two groups that realized a neuromuscular battery after beta-alanine (4.8 gr/daily during 4-weeks) or placebo (i.e., fructose) (4.8 grams/daily during 4-weeks). Before and after the supplementation period tennis performed a neuromuscular test battery in a tennis court consisted in different test such as; serve velocity, countermovement jump, isometric handgrip strength, 10-m sprint, modified 5-0-5 agility test and repeated sprint ability. After 48 h of the realization of neuromuscular test battery, tennis players performed VO2max consumption test (i.e., treadmill).
