Comportamento da percepção de estresse e variáveis bioquímicas e do desempenho de atletas de voleibol em um período preparatório

Abstract

RESTQ Sports, voleibol, Creatina quinase This study aimed to analyze the perception of stress and recovery, through RESTQ-Sport questionnaire, the plasma activity of the enzyme creatine kinase (CK) and performance tests through vertical jumps SJ, CMJ, CMJL in 7 different periods training (M1, M2, M3, M4, M5, M6 and M7) preparation for a competition, conducted over three months, where the M1 represented the payback period of the holiday and the rest when athletes were subjected to different levels training load. Participated in this study 13 high-level volleyball players, male, mean age 23.8 ± 5.4 years. Except from the general stress level, all other 18 stress and recovery perception scales were significantly different between the periods evaluated, always indicating increased levels of stress and decrease in recovery levels. The CK activity showed significant increases in the period M2, M3, M4, M5 and M6 compared to M1. With respect to performance testing during the periods M1, M4 and M7 was observed significant improvements over the periods, indicating that the training goal has been achieved, since the athletes showed improvement in yield. The results may indicate that despite variables used in monitoring training submit changes indicating a higher level of stress and muscle damage during the preparation, positive adaptation to training stimuli were obtained, indicating that these situations are normal in athletes who are submitted to different types of training.
