Summary

This study aims to investigate the effects of whole-body photobiomodulation on professional soccer players during a state championship. The primary question is whether photobiomodulation improves recovery, reduces muscle fatigue, and enhances performance compared to standard training without photobiomodulation.

Detailed description

Detailed Description: This randomized, controlled clinical trial aims to evaluate the effects of whole-body photobiomodulation (PBM) on recovery and performance in professional soccer players during a state championship. The intervention will be performed twice weekly on non-consecutive days for 8 weeks, in combination with each athlete's standard training routine. Participants will be allocated to either an active PBM group or a sham PBM group, both following identical procedures to maintain blinding. Throughout the study, participants will complete scheduled assessments at baseline, during, and after the 8-week period to monitor performance, muscle soreness, and hematological responses. Data will be analyzed using appropriate statistical tests, with a significance level of 5% (two-tailed).

Interventions

Type	Name	Description
RADIATION	Whole-Body Photobiomodulation (PBM) (Active PBM)	This intervention consists of whole-body photobiomodulation delivered using a full-body PBM device. Sessions are performed twice weekly on non-consecutive days for 8 weeks, coinciding with the athletes' standard training. The device emits therapeutic light at specified wavelengths and power, targeting the entire body. The protocol is standardized according to prior research, ensuring consistent exposure for all participants in the active arm. The intervention aims to improve muscle performance and recovery while reducing delayed onset muscle soreness (DOMS).
RADIATION	Sham PBM	Intervention Description (Sham PBM): Participants receive a sham photobiomodulation intervention using the same device and schedule, but without emission of therapeutic light. The procedure mimics the active intervention to maintain blinding while allowing comparison of outcomes, including muscle performance, DOMS, and blood markers.
