Effects of the infrared lamp illumination during the process of muscle fatigue in rats

In this study the effects of infrared lamp illumination during the muscle fatigue process was studied. Three different groups (n=5) were used: one control group and two treated (Infrared Lamp 780-1400nm), with the energy densities of 0.5 and 1.0 J/cm² and time of illumination of 300 seconds. The tre...
