Resumo

O alongamento é um recurso terapêutico manual comumente utilizado como medida profilática contra lesões e microlesões induzidas por exercício. Objetivou-se avaliar o efeito do alongamento após realização de exercício resistido na concentração sérica de CK em sujeitos saudáveis. 36 indivíduos, 18 homens e 18 mulheres foram divididos aleatoriamente em dois grupos, Controle (C) e Alongamento (A). Foi dosada a concentração de CK pré-exercício e após exercício para membros inferiores, imediatamente após o exercício os integrantes do grupo A realizaram alongamento ativo, sendo realizadas mais 3 coletas com intervalo de 24 horas entre estas. O grupo A apresentou um aumento na concentração CK 24 horas após o exercício. A medida da concentração de CK dos homens do grupo A apresentou diferença em relação à pré-exercício e em relação à medida de 24 horas do grupo controle, o mesmo comportamento não foi observado nas concentrações de CK das mulheres de ambos os grupos. O exercício realizado não foi suficiente para provocar micro-traumas no tecido músculo-esquelético, exceto o grupo A, indicando que o alongamento causou maiores injúrias ao tecido. sse mec este efeito relacionado ao o indutor de micro-lesrem. O alongamento após exercício resistido demonstrou efeito indutor de microtraumas no tecido músculo-esquelético, sendo os homens mais susceptíveis a este efeito.

Efect of stretching after exercise on serum cretine kinase of men and women

Abstract

The stretching exercise is usually used as a prophylactic way against damage in muscle induced by exercise. The objective of this study was to evaluate the effect of stretching after an resisted exercise in the serum concentration of creatine kinase, CK,  in healthy subjects. Thirty six subjects, 18 men and 18 women were random into two groups. Control (C) and Stretching (A). The concentration of CK was measured pre-stretching and pos-stretching for the lower limbs. Immediately after the exercise, the group A participants have performed the active stretching, and then other three blood collection were taken with a break of 24 hours between them. Group A showed an increase in CK concentration 24 hours after exercise and group A men´s CK concentration was different compared to the pre-stretching and in confrontation to the 24 hours measure of control group. The same behavior was not been observed in women CK levels in both groups. The exercise performed was not enough to cause micro lesions in musculoskeletal tissue, except in group A, wich is an indicative that stretching caused more muscle injuries. Stretching after resisted exercise demonstrated an induced effect of micro traumas in muscle tissue and that men were more likely to it.
