Abstract

Recent studies with photobiomodulation therapy have shown positive results delaying skeletal muscle fatigue and improving the status of biochemical markers related to skeletal muscle recovery when these therapies were applied before exercise. Some studies suggest that photobiomodulation therapy has systemic effects, but it is not known whether therapy exerts any systemic effects on human skeletal muscle. With these factors in mind, this research project aims to verify the local and systemic effects of phototherapy on muscle performance and recovery after exercise. It will be performed a randomized, double-blinded, placebo-controlled trial, with voluntary participation of 40 healthy subjects, non-atlhete, male, age between 18 and 35 years old. We will analyze parameters related to volunteers exercise performance (torque peak / maximum voluntary contraction - MVC), delayed onset muscle soreness (DOMS) by visual analogue scale (VAS), and biochemical marker of muscle damage (CK). The analysis will be performed before exercise protocols, after 1 minute, and 1, 24, 48, 72 hours after the end of exercise   protocol. (AU)
