Avaliação do desempenho de atletas universitários de uma equipe de rugby union após a utilização de diferentes estratégias de recuperação

Abstract

An alternative for rugby athletes is the post-exercise recovery that aims to minimize the risk of fatigue and optimize performance. However there is no consensus on the effectiveness of recovery strategies. The aim of this study was to evaluate the effectiveness of different recovery strategies on the performance of college athletes from a team of rugby union. For this two protocols were conducted. Protocol 1 examined different recovery strategies on the acute performance of college rugby union athletes. Eight athletes (23 ± 4.72 years; 87.46 ± 8.58 kg; 176.93 ± 4.49 cm), using a randomized crossover, were followed for four samples using the strategies cryotherapy (CWI), active recovery (AR) and ischemia-reperfusion (IR). Physical performance was analyzed (t test agility, countermovement vertical jumps, vertical jumps continuous 30s) at times: baseline, after completion of a training protocol (PT) immediately after recovery strategies (PR); and monitoring the variability heart rate (HRV). Data normality was verified by the Shapiro-Wilk test. For normal data, we used one-way ANOVA for repeated measures between strategies in each moment and two-way ANOVA for repeated measures to evaluate the different moments (Baseline, PT and PR), with Bonferroni post hoc test when appropriate. For nonnormal data we used the Friedman test and Dunn when necessary, with a significance level of 5 %. The results showed recovery strategies were not effective in improving the performance of acute college athletes from a team of rugby union (p> 0.05). Protocol 2 examined the CWI strategy on performance of college rugby union athletes 12h after its use. Were analyzed six athletes (20.5 ± 2.58 years, 79.0 ± 9.17 kg, 172.8 ± 4.73 cm) using a randomized crossover, followed for two samples using CWI. We used performance tests at baseline, PT, PR and 12h after, HRV monitoring and application of Total Quality Scale Recovery. When the data were normal, we used one-way ANOVA for repeated measures evaluating strategies at different times (Basal, PT, PR, after 12h) and Bonferroni post hoc test when appropriate. For non-normal data was used Friedman test followed by Dunn when necessary. To analyze the strategy at every moment used the Paired t test for normal data and Wilcoxon Paired t test for non-normal data with a significance level of 5 %. The CWI was effective in recovering physical performance, HRV and perceived recovery of athletes 12h after its use (p<0.05). Concluded with the two protocols that recovery strategies were not effective in improving the acute performance of collegerugby union athletes. However, it was found that the strategy CWI was effective in the recovery in the physical performance, HRV and perception of recovery of athletes 12 hours after its use.
