Resumo: | 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 treated animals were illuminated in one point directly in the tibialis muscle, after the first tetanic contraction out of six, with an interval between each tetany. The results were registered in an electrophysiograph and the intensity of the force of contraction in grams was analysed. It was observed that the control group presented a reduction in the intensity of the force of contraction, while the treated group managed to maintain it, which was clearly evident in the energy density of 0.5 J/cm². It was concluded that the use of the infrared lamp illumination was efficient concerning resistance to muscle fatigue.
