Photobiomodulation delays the onset of skeletal muscle fatigue in a dose-dependent manner

Author: Larkin-Kaiser KA, Borsa PA, Baweja HS, Moore MA, Tillman MD, George SZ, Christou EA

Double blind, placebo controlled, crossover study to examine dose response ergonomic properties of PBM therapy. Participants received 3 different doses of NIR light: sham, 240 J, and 480 J. Outcome measures included time to task failure (TTF), muscle fatigue, and muscle activity. The 240 J dose extended TTF by 26% compared to sham. Note: the 240 J dose corresponds to about 20 J/cm2 and 480 dose is 40 J/cm2.
