Summary

Muscle fatigue caused by physical training is understood as a condition related to the inability to maintain action potential, derived from the alteration in skeletal muscle homeostasis. In long-distance recreational runners, prolonged physical work is performed while maintaining the level of intensity, where a level of fatigue intervenes, which overlaps and generates tiredness to execute the movement continuously. In the last 10 years, sports supplementation has been explored as an aid to increase physical performance, improve muscle recovery and prevent sports injuries.
