Abstract

Overall, running have always been given special attention in major sporting events, from the shortest to the longest distances. Due to its relevance, efforts to understand the factors inherent to performance and the tools to develop it have emerged concomitantly. One of the most effective strategies for improving sports performance is resistance training (TR). TR is characterized by an increase in muscle contraction capacity. Given this characteristic, short-distance runners have been very privileged with this strategy. However, due to the lack of specificity, with consequent limited transfer to the technical sports gesture, the performance that can been enhanced arising from the TR become limited. Thus, strategies capable of reproducing the sporting gesture emerged as an alternative. In this context, the incorporation of wearable training technologies has been increasingly used, such as the Wearable Resistance (WR). Based on these findings, the objectives of this project are a) to verify the acute influence of running with and without WR on performance and kinematic variables; b) to compare the influence of WR or TR training over 6 weeks on kinematic variables, performance, strength and power output. For that, experienced sprinters will be evaluated in two moments; 1) evaluation of sprint performance and kinematics with and without WR, and, 2) determination of the effects of 6 weeks of training with and without WR on kinematics, as well as the comparison with the effects of TR, on performance, strength and power output parameters. The Shapiro-Wilk test will assess the normality of the data and t test will check the acute differences. For the chronic training effect, we will use one-way ANOVA to verify the differences between the groups, as well as the repeated measures ANOVA to verify possible differences between the moments and the Bayesian inference analysis for the probability of change between the variables.
