Brief Summary
Recent studies with photobiomodulation therapy have shown positive results in delaying skeletal muscle fatigue and improving performance through levels of biochemical markers and variables related to exercise when this therapy was 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 this factor in mind, this research aims to verify the local and systemic effects of phototherapy on muscle performance and recovery after exercise in healthy male participants. This research consists in a randomized, triple-blinded, placebo-controlled trial, with participation of 30 healthy subjects. Will be analyzed parameters related to exercise performance (peak torque in the maximum voluntary contraction test- MVC), delayed onset muscle soreness (DOMS) by visual analogue scale (VAS), and biochemical marker of muscle damage (CK) and blood Lactate (BL). The analysis will be performed before exercise protocol (baseline), after 1 minute of the exercise, and 1, 24, 48 and 72 hours after the end of exercise protocol

Outcome Measures
Primary Outcomes (6)
Maximum Voluntary Contraction
An isokinetic dynamometer (System 4, Biodex®, USA) will be used to assess muscle function and also for exercise protocol. Immediately after warm-up, volunteers will perform the maximum voluntary contraction test (MVC). Volunteers will be placed on the isokinetic dynamometer seated with a 100° angle between trunk and hip, and the non-dominant leg will be positioned to 60° knee flexion (0° corresponds to the total knee extension) and attached to the seat of the dynamometer through a belt. Volunteers will also be attached to the dynamometer seat through two straps on their trunk. MVC test consists of three isometric contractions of non-dominant lower limb knee extensors with a duration of 5 seconds and 30-second intervals between contractions, the highest torque value obtained at the three contractions (peak torque) will be used for statistical analysis.

- Masking Details
- Phototherapy pad with six clusters of 12 diodes each one will be placed in both legs. Only one researcher, that will be not involved with any procedure during data collection and analysis, will know about the phototherapy program used in which leg and randomization procedure. The light aspect is the same independent of the program (active or placebo) applied and all participants will wear a opaque glasses to protect against irradiation and also assure the blinding.
