More Info
Researchers gave 17 male subjects 630 nm (red) LED photon therapy after muscle-damaging eccentric exercise. If a bicep curl is positive movement, the uncurl is the negative or eccentric movement. The subjects had not done eccentric exercise as a focus of their workouts prior to this study.
Eight subjects got therapy and 9 were in the placebo group. All subjects did 30 eccentric contractions using their non-dominant arm.
Researchers tested isometric muscle strength, muscle soreness, elbow range of motion prior to exercise and at 24, 47, 72 and 96 hours after exercise.
The light therapy group getting 630 nm photons had significantly less muscle soreness even 96 hours after muscle damage occurred. They lost less muscle strength during recovery. They got these results with just one LED 630 nm treatment.
