L-Arginine Supplementation Improves Endurance Under Chronic Fatigue: Inducing In Vivo Paradigms with In Vitro Support

These findings demonstrate that L-arginine supplementation under chronic fatigue-inducing paradigms improves endurance and alleviates fatigue by enhancing energy metabolism, preserving glycogen, reducing muscle injury, and attenuating oxidative stress. L-arginine shows potential as a functional ingredient for promoting exercise performance and recovery.
