What this trial studies

This randomized, controlled trial will assign male professional soccer players to either active whole-body photobiomodulation or a sham procedure while they continue their regular training. Interventions are delivered twice weekly on non-consecutive days for 8 weeks at a single training center, with identical procedures used to preserve blinding. Participants undergo baseline, during-study, and post-intervention assessments of performance, muscle soreness, and hematological markers to monitor recovery and fatigue. Results will be compared between groups using standard statistical tests with a two-tailed 5% significance threshold.

Who should consider this trial

Good fit: Male professional soccer players aged 18–35 who are actively competing in the championship, train at least five times per week, and can attend all twice-weekly in-person sessions and assessments are ideal candidates.

Not a fit: Players with recent lower-limb injuries, chronic medical conditions, current use of other recovery therapies, known light sensitivity, or inability to comply with the schedule are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the therapy could accelerate recovery, reduce muscle soreness, and help players maintain higher performance levels during competition.

How similar studies have performed: Previous small athletic and clinical studies have reported promising but mixed results for photobiomodulation in reducing muscle fatigue and improving recovery, so this approach is somewhat supported but not definitively proven.
