Leucine and sport

In a nutshell

Exercise increases oxidation of amino acids such as leucine.

On the other hand, leucine is a powerful mediator of protein synthesis in muscle, promoting improved function, reduced fatigue and enhanced recovery from exertion. There is RCT evidence that leucine improves sports performance, particularly for endurance activity, but more evidence is still needed.
