简要总结
It is well documented that exercise-induced muscle damage (EIMD) decreases muscle function and causes severe soreness and discomfort. Branched-chain amino acid (BCAA) supplementation has been shown to increase protein synthesis and decrease muscle protein breakdown, however, the effects of BCAAs on recovery from EIMD are unknown. Thus, the aim of this study was to examine the effects of a BCAA supplement on markers of muscle damage.

结局指标
主要结局
Maximal voluntary contraction
时间窗: pre exercise, 24 h, 48 h, 72 h, 96 h post-exercise
Isometric MVC of the participants' dominant knee extensors was assessed using a strain gauge. MVCs were performed for 3 s with a 60 s rest between each repetition.
次要结局
- Limb girths(pre-exercise, 24h, 48h, 72h, 96h)
- Vertical jump(pre-exercise, 24h, 48h, 72h, 96h)
- Creatine kinase(pre-exercise, 24h, 48h, 72h, 96h)
- Muscle soreness(pre-exercise, 24h, 48h, 72h, 96h)
