Respostas agudas e tardias da creatina quinase após duas configurações distintas de treinamento resistido

Abstract

The present study investigated the effect of two resistance training sessions (hypertrophy vs. resistance) on muscle damage 24 and 48 hours post-exercise. Six young men underwent two RT protocols for the entire body, one being a resistance training protocol for hypertrophy (HRT; 75% 1-RM, 8-12 repetitions) and a resistance training protocol for resistance (RRT; 15% 1-RM, 50-60 repetitions). Statistically significant differences (p <0.05) were found in blood CK concentrations between pre- and 24-hour post-exercise values in HRT. There were no differences between groups or between the results of different moments of collection in RRT. It is concluded that the HRT protocol induces a statistically significant increase in CK expression 24 hours after its application and that this expression does not remain high 48 hours after using this protocol. Finally, the TRR protocol showed no differences in blood CK concentrations.
