l‐citrulline has recently been reported as a more effective supplement for promoting intracellular nitric oxide (NO) production compared to l‐arginine. Here, the effect of l‐citrulline on skeletal muscle and its influence on exercise performance were investigated. The underlying mechanism of its effect, specifically on the expression of skeletal muscle peroxisome proliferator‐activated receptor‐gamma coactivator‐1α (PGC‐1α), was also elucidated.

补充 l-瓜氨酸-增加骨骼肌 PGC-1α 表达与运动表现和增加骨骼肌重量相关

最近有报道称，与L-精氨酸相比， L-瓜氨酸是促进细胞内一氧化氮 (NO) 产生更有效的补充剂。在此，研究了L-瓜氨酸对骨骼肌的作用及其对运动表现的影响。其影响的潜在机制，特别是对骨骼肌过氧化物酶体增殖物激活受体-γ共激活剂-1α（PGC-1α）表达的影响，也得到了阐明。
