On the issue of improving the performance of athletes through the "supplement" of L-arginine
Currently, the effectiveness of oral usage of L-arginine and its precursor L-citrulline as donors of nitrogen monoxide (NO), which induces vasodilation of arterial and venous blood vessels, thereby con tributing to the improvement of blood flow, and mitochondrial processes (ATP resynthesizes), which presumably makes it possible to optimize energy metabolism, delay fatigue, and improve the performance of athletes. However, an analysis of the work of a number of researchers showed that isolated oral intake of L-arginine or L-citrulline "far" did not always contribute to improving the performance of athletes. A more pronounced effect in maintaining the performance of athletes has a combined intake of L-citrulline with malate.
