Correlação entre termografia infravermelha e marcadores de dano muscular após protocolo de salto em ambiente controlado

Abstract

Objective: The objective of this study is to correlate infrared thermography with muscle damage markers after a plyometric jumping protocol performed in a controlled environment. Materials and Methods: The sample consisted of physically active male participants with ages ranging from 18 to 30 years. The subjects were divided into two groups, one control and the other experimental group. Upon arriving in the laboratory, the individual performed the following collections: capillary blood sample, subjective pain scales, thermographic evaluation and jump test. Then he performed the plyometric jump protocol. At the moments related to recovery to the proposed exercise, 24 hours, 48 hours and 72 hours after the above procedures were performed again. Results: The results showed an increase in creatine kinase concentration (p <0.05) and delayed onset muscle pain (p <0.05) 24 hours after the plyometric jumping protocol, with no change in the irradiated temperature of the thigh skin. C-reactive protein and myoglobin showed no increase in their concentrations as there was no difference in the performance of crouching and countermovement jumps. Discussion: Thermography values did not correlate with muscle damage markers; however, the results indicate that a plyometric jumping session induces a change in creatine kinase concentration and delayed onset muscle pain, with no deterioration in performance over the course of days. Some variables related to these studies may explain in part the divergent results, such as different types of protocol applied, level of training of the evaluated, and different methods of selection of the region of interest, so the combination of these multifactors may contribute to the divergence of the results demonstrated. Conclusion: In this way it can be concluded that a plyometric jump session changes some markers of muscle damage, but does not alter the temperature of the thighs, generating a non-correlation with the markers of muscle damage.
