Effect of Low Reactive-Level Laser Therapy or Light-Emitting Diode Therapy on Muscle Fatigue Resistance

Abstract

Recently, many studies have reported that low reactive level laser therapy (LLLT) or light emitting diode therapy (LEDT) is effective in reducing muscle fatigue, enhancing muscle performance, and training effect. In this review, the author will discuss the effectiveness of LLLT/LEDT in several conditions that can induce muscle fatigue and the mechanisms underlying improvement of muscle fatigue by light therapy.
