Efeito da utilização da vestimenta de assistência elástica 'Slingshot' no número máximo de repetições no supino reto horizontal livre

Abstract

The Slingshot elastic assistance vestment has been used to improve the performance of 1RM in the bench press exercise, in addition to increase the volume within a set in the exercise. This study purpose is to investigate if the use of Slingshot is effective to increase the number of repetitions in trained men, and also if the use of Slingshot in a different position from other studies will take different results. Eleven resistance trained men participated in the study. The minimum practice time required was 3 years, whose interruptions during these years did not exceed 30 continuous days. Three different sessions were performed, with a 48­hour interval among them. In the first session, they performed the familiarization of the 1RM test and the Slingshot vestment use by performing eight to ten repetitions at 50% of 1RM. In the second session, they performed the 1RM test, and, after resting twenty minutes, performed one of two randomized experimental conditions. In condition 1, they performed three sets of NMR (maximum number of repetitions) at 80% of 1RM using Slingshot (with SS) and in condition 2 performed the same three sets of NMR at 80% of 1RM without using Slingshot (without SS). After two days, in the third and last session the subjects reversed the experimental conditions. The use of Slingshot (SS) increased the number of repetitions in the bench press exercise for resistance trained men. The use of Slingshot in a different position had similar results comparing the other studies by improving performance. The use of Slingshot provided a shorter average duration of repetition (p = 0.08, effect size = 0.21 and Power = 0.84), but there was no vestment and series interaction. The results of this study indicate that Slingshot can be used in work out gyms and by trained individuals as an implement to achieve different goals such as increased volume.
