“…The authors reported an increased number of repetitions in the LLLT group compared to the placebo, but surface electromyography showed no statistical difference. In a similar study, Dos Santos Maciel, Munoz (level 1b) used a muscular preconditioning protocol with LLLT (780 nm) applied on the tiabialis anterior muscle and investigated fatigue in an isokinetic dynamometer combined with surface electromyography analysis. This double‐blind controlled trial reported an increased torque exerted by the tiabialis anterior muscle after muscular preconditioning, but muscle fatigue analyzed by surface electromyography was not reduced, and lactate levels in blood were not significantly different between groups.…”

Photobiomodulation (PBM) describes the use of red or near-infrared (NIR) light to vstimulate, heal, and regenerate damaged tissue. Both pre-conditioning (light delivered to muscles before exercise) and PBM applied after exercise can increase sports performance in athletes. This review covers the effects of PBM on human muscle tissue in clinical trials in volunteers related to sports performance and in athletes. The parameters used were categorized into those with positive effects or no effects on muscle performance and recovery. Randomized controlled trials and case-control studies in both healthy trained and untrained participants, and elite athletes were retrieved from MEDLINE up to 2016. Performance metrics included fatigue, number of repetitions, torque, hypertrophy; measures of muscle damage and recovery such as creatine kinase and delayed onset muscle soreness. Searches retrieved 533 studies, of which 46 were included in the review (n=1045 participants). Studies used single laser probes, cluster of laser-diodes, LED-clusters, mixed clusters (lasers and LEDs), and flexible LED arrays. Both red, NIR, and red/NIR mixtures were used. PBM can increase muscle mass gained after training, and decrease inflammation and oxidative stress in muscle biopsies. We raise the question of whether PBM should be permitted in athletic competition by international regulatory authorities.

“…In physically active young women, treatment with photobiomodulation (780 nm, energy of 23.49 J per muscle) before the induction of a protocol of tibialis anterior muscle fatigue increased muscle torque at the beginning of the exercise, compared to the placebo ( dos Santos Maciel et al, 2014 ).…”

Photobiomodulation has been shown to improve tissue and cell functions. We evaluated the influence of photobiomodulation, using a B-Cure laser, on: 1) maximal performance, and 2) muscle recovery after resistance exercise. Two separate crossover randomized double-blinded placebo-controlled trials were conducted. Sixty healthy physical education students (28 men, 32 women), aged 20-35, were recruited (30 participants for each trial). Participants performed two interventions for each experiment, with real lasers (GaAlAs, 808 nm) on three quadricep locations in parallel (overall treatment energy of ~150J) or sham (placebo) treatment. In the first experiment muscle total work (TW) and peak torque (PT) were measured by an isokinetic dynamometer in five repetitions of knee extension, and in the second experiment muscle recovery was measured after the induction of muscle fatigue by evaluating TW and PT in five repetitions of knee extension. There were no differences between treatments (real or sham) regarding the TW (F(1,28) = 1.09, p = .31), or PT (F(1,29) = .056, p = .814). In addition, there was no effect of photobiomodulation on muscle recovery as measured by the TW (F(1,27) = .16, p = .69) or PT (F(1,29) = .056, p = .814). Applying photobiomodulation for 10 min immediately before exercise did not improve muscle function or muscle recovery after fatigue.

“…The positive effects seen in recent studies were obtained with red 8,9 and infrared wavelengths 9-13 generated by both laser [8][9][10][11][12][13][14] and LED [14][15][16][17] devices. Various exercises that represent sport-specific activities have been tested: repeated contractions, 8,10,11,13,15 isometric sustained contraction, 9,16,17 cycling, 14 and running. 12 Only a few investigators have compared PBM with other physical agents 18,19 and addressed the effectiveness of laser versus LEDs.…”
