The effect of illumination during the aerobic phase of strenuous exercise has not been studied. The investigators hypothesize that the increased energy donated to cells during the aerobic phase will significantly delay muscle fatigue. A novel aspect of this study is to include simultaneous treatment with near infrared light at 800 nm and 905 nm. Fatigue index and change in lactate blood level will be used to compare the different laser treatments for each participant. Monte Carlo simulations of light energy reaching the muscle will be carried out, based on skin-fold thickness measurements of each participant. The investigators believe this will be the first report of optical dosimetry as a function of adipose thickness and it will enable estimation how much of the light applied to the skin surface is able to penetrate to the muscles that are thought to be affected. The results of this study will help clinicians to optimize treatment for individual patients.",[83],"Muscle Fatigue",[85],"Low-Level Light Therapy","COMPLETED","2018-03-05",{"date":89,"type":77},"2018-03-12",{"date":91,"type":77},"2017-02-20",{"date":93,"type":77},"2017-07-31",{"name":5,"class":6},1]
