Low Level Light Therapy Study Treating Muscle Fatigue

Nov 08

Low Level Light (or Laser) Therapy, also sometimes referred to as “Phototherapy”, was the subject of a recent study that sought to compare the effects of red and infrared LLLT on skeletal muscle fatigue in humans. A randomized double-blind placebo-controlled crossover trial was performed on 10 healthy male volunteers. They were treated with active red LLLT (660nm) and active infrared LLLT (830nm) or an identical placebo at identical locations before exercise. The study concluded that both red LLLT and infrared LLLT therapy were significantly better in delaying muscle fatigue than placebo and, further, that there was no significant difference in result between the two active LLLT therapies.
