Influência da utilização do hand grip na performance de praticantes de crossfit® nos exercícios suspensos na barra

Abstract

CrossFit® is a modality that has been gaining prominence in recent times and there are still few studies on the influence of some equipment and/or accessories on the performance of practitioners. This study analyzes the influence of hand grip on the performance of CrossFit® practitioners in exercises suspended on the bar, namely: kipping toes to bar and kipping pull up. The study included 30 healthy adults, of both sexes, aged between 20 and 53 years (30.8 ± 7.4 years), practitioners of CrossFit® for at least 6 months (mean 36.1 months) and capable of performing at least 5 consecutive repetitions of the aforementioned movements. To verify whether there was a significant difference in performance with the use of the hand grip, the paired ttest was used with p<0.05. The results showed that the use of hand grip allows a better performance of the kipping toes to bar and kipping pull up movements (20.8 ± 6.6 repetitions and 19.17 ± 5.55 repetitions; respectively) than without its use (15.6 ± 6.3 repetitions and 13.83 ± 5.59 repetitions, respectively) (p<0.001). The use of hand grip had a lower subjective perception of effort, both in kipping toes to bar and in kipping pull up, but these differences were not statistically significant. Given the above, it is possible to conclude that the use of handgrip can promote an improvement in the performance of CrossFit® practitioners with regard to the maximum number of repetitions of the two suspended movements on the bar tested in this study: kipping toes to bar and kipping pull up.
