NIR Wavelengths for Muscle Recovery

Near-infrared light (800–880nm) is the relevant spectrum for muscle recovery applications. Penetration depth in the 800–880nm range is approximately 20–40mm — sufficient to reach skeletal muscle tissue, particularly in the extremities.

The most commonly studied NIR wavelength for musculoskeletal applications is 830–850nm. Published research on DOMS reduction, strength recovery, and exercise performance primarily uses this range. 810nm has been used in neurological applications and some musculoskeletal studies. All reviewed panels include at least one NIR wavelength in the 830–850nm range.

For serious athletes treating the full body post-training, the choice between a large panel and multiple sessions with a mid-size panel is practical rather than efficacy-driven — the light output per session is the critical variable.
