Sponsor's own description

The photobiomodulation (PBM) shows positive results in muscle performance, fatigue reduction, management of blood lactate production, analgesia and in the increase of VO2 maximal, favoring the increase of ATP production and thus the energy metabolism. The association of PBM applied before high-intensity treadmill training shows physiological improvements both in normoxic (Nor) and hypoxic (Hip) conditions. Anaerobic capacity (AC) is the maximum amount of ATP that can be resynthesized by anaerobic metabolism and is an important predictor of high-intensity exercise since an athlete's ability to perform efforts to increase maximal oxygen consumption (VO2max) depends on AL. In view of the above information the main objective of the present research project will be to investigate the effects of PBM on AC under normoxic and hypoxic conditions in amateur runners. To test the effects of exercise training on anaerobic capacity under normoxic and hypoxic conditions, 7 individuals will be randomly submitted to four maximal efforts to exhaustion with intensity corresponding to 110% of VO2max in Hip, Nor, Hip+Ebio and Nor+Ebio conditions. These efforts will be used to estimate the AC, that is, the maximum accumulated deficit of alternative oxygen (MAODRED), from the sum of the energy contribution of the anaerobic and lactic metabolisms.
