Brief Summary
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.

Beta-alanine supplementation
ACTIVE COMPARATORBeta-alanine (4.8 grams) pills (Crown Nutrition, Haro, Spain) in four doses each day during a 4-week supplementation period.
Placebo supplementation
PLACEBO COMPARATORPlacebo (4.8 grams) pills (Crown Nutrition, Haro, Spain) contain fructose (300mg) and excipients (1200 mg) such as cellulose, calcium phosphate, silicon dioxide and magnesium stearate in four doses each day during a 4-week supplementation period.
Interventions
In a randomized order, two groups (n=7) was randomly assigned to beta-alanine and placebo during a 4-weeks period
