Power production in intermittent exercise of short term after two protocols of heating
Abstract
In the absence of evidence to support the use of static stretching to increase the physical performance the research turned to the warm-up procedures, which aims to prepare the body for more intense physical activity. The results of this study may contribute to the understanding of the effect of various warm-up protocols on exercise performance. The aim of this study was to compare the intermittent exercise performance two warm-up protocols. Eight physically active male subjects participated of this study. The intermittent exercise involved ten all-out 6-s cycling sprints on a cycle ergometer, loaded to 7,5% of body weight, interspersed with 30 seconds of passive recovery. The warm-up protocol A involved a intermittent warmup, five minutes, with three all-out six seconds and increasing work rate. The warmup protocol B involved five minutes of continuous exercise. Shapiro-Wilk normality test was used, after Shapiro-Wilk test, T-test and the Wilcoxon test was used according to data distribution. There were significant differences in favor of warm-up protocol A in the higher power generated during the test and for the first three blocks of effort. These results suggest that performance during short bout of high-intensity intermittent exercise is influenced by warm-up type.
