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

Conditions

  • Phototherapy
  • Low-level Laser Therapy
  • Systemic

Interventions

DEVICE

Phototherapy

The Photobiomodulation Therapy will be applied 3 minutes after MVC test in 6 points of the quadriceps muscle (2 points in vastus lateralis, 2 in rectus femoris and 2 in vastus medialis).
