Infrared Laser Improves Collagen Organization in Muscle and Tendon Tissue During the Process of Compensatory Overload
Summary
This study examined the effects of infrared laser therapy (LLLT) on collagen deposition and organization in muscle and tendon tissue during compensatory overload in rats. After the removal of synergist muscles, animals were divided into control, hypertrophy, and hypertrophy + LLLT groups. Infrared laser therapy (780 nm, 40 mW) was applied daily. At 7 days, treated muscles showed increased collagen content and better fiber organization. At 14 days, collagen levels decreased in muscle, while tendon fibers remained well-organized. These findings suggest that LLLT helps regulate collagen remodeling, potentially aiding recovery from muscle overload.
