“…This study also demonstrated positive responses of the previous LED application in the blood lactate disappearance capacity; these effects could be due the improvement in microcirculation [6,29] and also because of a decreased lactate production with prior application of light by modifications on oxidative capacity through enzymatic, mitochondrial, and systemic changes, facilitating the resynthesis of ATP by the alactic pathway [20,21,29]. Although there was no difference between conditions for LA peak , LED condition presented higher removal capacity compared to PLA, with significantly lower values of LA 13-min and LA 15-min .…”

This study aimed to investigate the effect of prior LED sessions on the responses of cardiorespiratory parameters during the running incremental step test. Twenty-six healthy, physically active, young men, aged between 20 and 30 years, took part in this study. Participants performed two incremental load tests after placebo (PLA) and light-emitting diode application (LED), and had their gas exchange, heart rate (HR), blood lactate, and rating of perceived exertion (RPE) monitored during all tests. The PLA and LED conditions were compared using the dependent Student t test with significance set at 5%. The T test showed higher maximum oxygen uptake (VO) (PLA = 47.2 ± 5.7; LED = 48.0 ± 5.4 ml kg min, trivial effect size), peak velocity (V) (PLA = 13.4 ± 1.2; LED = 13.6 ± 1.2 km h, trivial effect size), and lower maximum HR (PLA = 195.3 ± 3.4; LED = 193.3 ± 3.9 b min, moderate effect size) for LED compared to PLA conditions. Furthermore, submaximal values of HR and RPE were lower, and submaximal VO values were higher when LED sessions prior to the incremental step test were applied. A positive response of the previous LED application in the blood lactate disappearance was also demonstrated, especially 13 and 15 min after the test. It is concluded that LED sessions prior to exercise modify cardiorespiratory response by affecting running tolerance during the incremental step test, metabolite clearance, and RPE. Therefore, LED could be used as a prior exercise strategy to modulate oxidative response acutely in targeted muscle and enhance exercise tolerance.

“…A relatively novel treatment option in equine medicine is high-power laser therapy. In human medicine this therapy has been successfully used to address multiple orthopedic pathologies (4)(5)(6)(7). In a single blinded randomized clinical study in human Achilles tendinopathy, highpower laser therapy significantly reduced pain (8).…”

“…Investigators [4][5][6][7] have begun to explore the ergogenic effects of NIR light therapy in reducing skeletal muscle fatigue and attenuating strength loss during and after resistance exercise. Previous authors [8][9][10] have provided evidence for the ability of light therapy to enhance blood circulation, resulting in an increase in tissue oxygenation. Increasing circulation in the irradiated tissue can lead to enhanced oxygen and substrate delivery, thereby improving the overall ability of the muscle to perform work.…”

Context: Near-infrared (NIR) light therapy is purported to act as an ergogenic aid by enhancing the contractile function of skeletal muscle. Improving muscle function is a new avenue for research in the area of laser therapy; however, very few researchers have examined the ergogenic effects of NIR light therapy and the influence it may have on the recovery process during rehabilitation.Objective: To evaluate the ergogenic effect of NIR light therapy on skeletal muscle function.Design: Crossover study. Main Outcome Measure(s): The dependent variables were elbow range of motion, muscle point tenderness, and strength (peak torque). Analysis of variance with repeated measures was used to assess changes in these measures between treatments at baseline and at follow-up, 48 hours postexercise. Additionally, immediate strength loss postexercise was compared between treatments using a paired t test.Results: Preexercise to postexercise strength loss for the active laser treatment, although small, was less than with the sham treatment (P ¼ .05).Conclusions: Applied to skeletal muscle before resistance exercise, NIR light therapy effectively attenuated strength loss. Therefore, NIR light therapy may be a beneficial, noninvasive modality for improving muscle function during rehabilitation after musculoskeletal injury. However, future studies using higher treatment doses are warranted.
