RESUMO:

Introduction: Exercise-induced muscle damage usually occurs with the usual practice of physical exercise, and its magnitude is directly related to the type, intensity, mode or duration of the exercise. The evaluation of DMIE by indirect methods has been increasingly used and more recently, infrared thermography has been used as another instrument to measure muscle damage, however, the physiological behavior of the superficial temperature is not known before different DMIE. Objective: To evaluate the physiological behavior of superficial skin temperature after high and low volume induced muscle damage in the elbow flexors, analyzing if there is difference between different magnitudes of damage and if the temperature is related to the main indirect markers. Methods: This was a short longitudinal study in which 30 healthy, active men who did not perform any strength and / or endurance training were randomly assigned to the low (gBV) and high-volume groups (gAV). Subjects were evaluated for skin temperature (thermography), clinical indicators (subjective perception of pain, range of motion, subjective perception of effort), biochemical indicators (CK blood concentration), and neuromuscular indicators by means of an isometric variable of torque). The evaluations occurred 48 hours pre-protocol, immediately before and after, plus 30 minutes, 24, 48 and 72 hours after the DMIE protocol. The gBV group performed 10 eccentric contractions of elbow flexors on the isokinetic dynamometer with the angular velocity of 60 ° / s in a range of elbow flexion / elbow extension of 120 ° and gAV performed the same exercise, however with 30 contractions eccentric Data were analyzed using the statistical software SPSS 20.0, and the significance level was set at 5%. Results: There was a temperature increase at the moment immediately after the stimulus in both groups (p <0.05), but returning after 30 minutes and without differences between them (p> 0.05). Regarding the markers (Peak torque, Pain, CK, ROM, Threshold of pressure pain and Circumference), all presented change over time, with a difference between the groups in some moments evaluated. There was no correlation of temperature with the main indirect markers of muscle damage (Pico Torque, Pain and CK) (p> 0.05). Conclusion: The skin surface temperature increases only at the moment immediately after the stimulus, with no differences between magnitudes of muscle damage and no relation to the main indirect markers of muscle damage. Therefore, skin surface temperature can not be considered an indirect marker for assessing muscle damage
