Photobiomodulation in Human Muscle Tissue
Share
This review examines the effects of photobiomodulation (PBM) on human muscle tissue, particularly in exercise performance, muscle recovery, and tissue repair. PBM uses red or near-infrared light to stimulate biological processes that may improve muscle function and reduce damage. The review analyzes evidence from human studies involving PBM applied before or after physical activity.
The article explains that PBM primarily works by stimulating mitochondrial activity, which increases ATP production, reduces oxidative stress, and improves cellular metabolism. These effects may enhance muscle endurance, reduce fatigue, improve recovery, and decrease exercise-induced muscle damage and inflammation.
The review found that PBM may help improve muscle performance, strength recovery, delayed-onset muscle soreness (DOMS), and tissue repair, although treatment outcomes vary depending on factors such as wavelength, dosage, treatment timing, and irradiation site. The authors also emphasized the need for standardized protocols and further clinical studies.
Key takeaway: PBM shows promising benefits for muscle recovery and performance enhancement, but treatment success depends heavily on correct treatment parameters and stronger clinical evidence.
