Summary

The effects of phototherapy has been widely studied by some research groups. The investigators know that there are positive results with light application to improve muscle performance and delay fatigue. However, there are few studies showing its´ effects on muscular training. Therefore, the aim of this study was to assess the effects of phototherapy applied at different times during 12 weeks of strength training. For such, 48 volunteers, healthy male, from 18 to 35 years old were recruited to perform a strength training protocol for the anterior muscle of the thigh development. Volunteers performed the training protocol twice a week for 12 weeks. There were assessed isometric peak torque in isokinetic dynamometer, 1-repetition maximum test in the leg extension and leg press machines and bilateral thigh perimetry.

Conditions

  • Muscle Development in Association to Phototherapy

Interventions

DEVICE

Active or Placebo Phototherapy (MR4)

Participants performed a strength training. Forty-eight subjects practiced a training protocol with 80% of the load, measured through 1-repetition maximum test. The strength training lasted 12 weeks and the evaluations were done monthly. Phototherapy, active or placebo, were applied in 6 different points of quadriceps muscle depending the group randomized, before and after each training session.
