Summary

Recent studies with photobiomodulation therapy (PBMT) have shown positive results delaying skeletal muscle fatigue and improving the status of biochemical markers related to skeletal muscle damage when these therapies were applied before exercise. The aim of this project is to verify the effects of PBMT in improvement of skeletal muscle performance and skeletal muscle recovery in healthy male subjects. This project aim also to validate the concept that simultaneous use of three wavelengths and light sources lead to optimized action independently of time-window between irradiation and the exercise.

Detailed description

This is a randomized, triple-blinded, placebo-controlled trial. Sixty healthy untrained male subjects will be randomly allocated to six experimental groups: Placebo, Control, PBMT 5 mins, PBMT 3h, PBMT 6h and PBMT 24 hours. PBMT will be applied precisely two minutes after baseline MVC test. Then, after five minutes, 3, 6 hours or 1 day (24 hours) of PBMT the eccentric exercise protocol will be performed. We will analyze maximum voluntary contraction (MVC), creatine kinase (CK) activity and delayed onset muscle soreness (DOMS). Assessments will be performed at baseline, immediately after (1 minute), 1 hour, 24 and 48 hours after the eccentric exercise protocol.
