Light therapy involves the application of light to a tissue to promote healing and functional recovery. Near-infrared light modalities emit photons in a narrow bandwidth with wavelengths ranging from 700 to 1000 nm. Positive therapeutic effects of light therapy are attributed to its ability to transmit photons through the skin to penetrate deeper into soft tissues, where the photons are absorbed by cellular and blood-bound proteins known as chromophores. Photon absorption by endogenous chromophores stimulates biochemical reactions in tissues that translate to improvements in cellular growth, repair, and function.

Increasing circulation in the irradiated tissue can lead to enhanced oxygen and substrate delivery, thereby improving the overall ability of the muscle to perform work. An increase in oxygen delivery to the working muscle will also lead to increased adenosine triphosphate (ATP) production via aerobic respiration. With increased ATP bioavailability, the local musculature is able to perform more work and resist fatigue more readily as it limits the accumulation of metabolites and the impairment of oxygen delivery. Enhancement of blood flow, oxygen delivery, and ATP synthesis within working muscle provides a physiologic basis of support for light therapy as an ergogenic aid.

Near-infrared (NIR) light therapy is claimed to enhance the contractile function of skeletal muscle, acting as an ergogenic aid. This represents a novel research direction in laser therapy. However, the impact of NIR light therapy on muscle recovery during rehabilitation has been scarcely investigated.



Objective:

To assess the ergogenic effect of NIR light therapy on skeletal muscle function.

Design:

Crossover study.

Setting:

Controlled laboratory environment.



Participants:

Thirty-nine healthy individuals, including 21 men and 18 women, with an average age of 20.0 ± 0.2 years, height of 169 ± 2 cm, weight of 68.4 ± 1.8 kg, and body mass index of 23.8 ± 0.4 kg/m².

Intervention:

Each participant received both active and sham treatments on the biceps brachii muscle on two different days, in a randomized order. The active treatment utilized a class 4 laser delivering a cumulative dose of 360 J. Following each treatment, participants completed an elbow-flexion resistance exercise protocol.



Main Outcome Measures:

The study measured elbow range of motion, muscle point tenderness, and strength (peak torque). Repeated measures analysis of variance was used to evaluate changes in these measures from baseline to 48 hours post-exercise. Immediate post-exercise strength loss was also compared between treatments using a paired t-test.



Results:

The strength loss from pre-exercise to post-exercise was less with the active laser treatment compared to the sham treatment, although the difference was small (P = .05).



Conclusions:

NIR light therapy, when applied to skeletal muscle before resistance exercise, effectively reduced strength loss. This suggests that NIR light therapy could be a valuable, noninvasive method for enhancing muscle function during rehabilitation following musculoskeletal injuries. Future studies with higher treatment doses are recommended.
