Researchers are evaluating the effects of whole-body photobiomodulation (PBM) on recovery, muscle fatigue, and performance in professional male soccer players aged 18 to 35 during a state championship. The study compares PBM combined with standard training to standard training alone without PBM, aiming to see if PBM improves muscle recovery and athletic performance over an 8-week period. Participants will be randomly assigned to either an active PBM group or a sham PBM group. Both groups will receive treatments twice weekly on non-consecutive days for 8 weeks, alongside their usual training routines. The active group will use a full-body PBM device that emits therapeutic light at specific wavelengths, while the sham group will undergo identical procedures without actual light emission to maintain blinding. Throughout the study, assessments for muscle soreness, performance, and blood markers will be conducted at baseline, weekly during the intervention, and at the end of 8 weeks. Delayed onset muscle soreness (DOMS) will be measured regularly to monitor recovery. The study includes monitoring of muscle fatigue and hematological responses to evaluate the effects of PBM, with data analyzed using appropriate statistical methods.
