Low-level Laser Therapy clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Influence of PBM on Anaerobic Capacity Under Normoxia and Hypoxia

Start date: August 31, 2021
Phase: N/A
Study type: Interventional

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.
