Abstract

Traditionally in swimming, heating protocols are applied in high volume and moderate intensity. However, evidence shows that the use of high intensity efforts, especially exercises that involve the development of strength, can bring some benefit to the swimmer, recognized effect as post-activation potentiation (PAP). The studies carried out on this subject used different models of exercise for empowerment, demonstrating benefits to the output block or clean swimming during the race. Whereas the performance depends on both instances, the use of a hybrid model for the PPA would be of great practical advantage, which has not found in the literature. Thus, the aim of this study is to test the possibility of using a hybrid model for PPA. For this, 17 swimmers will perform four potentiation protocols, followed by a maximum performance of 50m. In the first protocol participants will perform a standard heating without PPA (control condition). In the second protocol, the swimmers will be subjected to years of "progress". In the third, they carry out efforts in the horizontal bar and jump on the crate. Finally, in the fourth protocol, the swimmers will be submitted to the hybrid protocol, which shall consist of exercises both the second and the third protocol. A 24 range will be respected between each protocol. In addition to performance, this project will determine the neuromuscular responses induced by different protocols. For this, the Twitch interpolation technique which allows determining the level of voluntary muscle activation may be used. Furthermore, the mechanical parameters are determined during swimming performance. Confirmed the normality of the data, the responses observed in the different protocols are compared using analysis of variance for repeated measures followed by post hoc Tukey (p <0.05).
