Summary

Introduction: Recent studies have shown positive results from the application of phototherapy for the improvement of performance and acceleration of the recovery process both in the application before and after exercise. However, the effects of phototherapy during combined training and after a primary adaptation process remain unclear.

Research objectives: The primary objective of the study is to analyze and compare the effects of phototherapy using different light sources (laser and light emmiting diode - LED) interacting with combined training on clinical, functional, and psychological outcomes and vascular endothelial growth factor. The secondary objective is to compare the benefits provided by phototherapy in participants with different levels of training adaptation.

Design: A controlled trial, double-blind, placebo-controlled will be conducted with stratified randomization and concealed allocation.

Participants and Setting: After fulfilling the eligibility criteria, forty-five male participants will participate in the study.

Procedure: In phase 1, the participants will perform six-weeks of combined training (sprints and squats). In phase 2, participants will be allocated, through stratified randomization (based on adaptation capacity to training), into three groups: active phototherapy group (AG), placebo phototherapy group (PG), and control group (CG). A new six-week training period will then start. In this phase the participants will carry out training normally with the adjusted loads and between sprints and squats will receive the recovery strategy related to the group to which they belong.

Intervention: Active and placebo phototherapy will be applied by a trained therapist, between sprints and squats. During the period of recovery strategies for the AG and PG, the CG participants will remain seated for passive recovery, supervised by an independent therapist.

Measurements: The measurements include clinical, functional, and psychological outcomes and vascular endothelial growth factor.
