Exercise- and diet-induced glycogen depletion impairs performance during one-legged constant-load, high-intensity exercise in humans
Exercise- and diet-induced low muscle glycogen content impairs high-intensity constant-load exercise performance lasting approximately 5 min. This was observed even with concomitantly better single-twitch contractile characteristics and similar reduction in MVC after task failure compared to glycogen-loaded legs. At rest, glycogen levels did not affect MVC and contractile characteristics.
