Abstract Recent studies with phototherapy 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. However, several factors still remain unknown such as: optimal doses and treatment parameters, mechanisms, the effects in long-duration exercises and long-term effects in skeletal muscle recovery. At same way, still it is not completely known the effects of combination of different light sources (lasers and LEDs) on skeletal muscle performance and recovery after exercise. With these factors in mind, the aims of this project are: To evaluate the long-term effects of phototherapy with the combination of different light sources on skeletal muscle performance and post-exercise recovery. It will be performed a randomized, double-blinded, placebo-controlled trial, with voluntary participation of healthy subjects. We will analyze parameters related to volunteers exercise performance (torque peak / maximum voluntary contraction - MVC), delayed onset muscle soreness (DOMS), and biochemical marker of muscle damage (CK). The analysis will be performed before exercise protocols, after 1 minute, and 1, 24, 48, 72 and 96 hours after the end of exercise protocol. | |
