Efeitos de dois modelos de treinamento em parâmetros de performance de atletas juvenis de rugby sevens feminino

Abstract

The present study aimed to compare the effects of two training models on linear speed, change of direction speed and on jump height with and without countermovement in youth female rugby sevens athletes. The sample consisted of 10 athletes, who were randomly distribuited into two groups, which were divided into six weeks of plyometric training, and resisted sprint training using a total overload of 13% of each athlete's body mass. The linear displacement time of 10 and 20 meters were measure, in addition to displacement with change of direction and jump height with and without countermovement. An two-measures ANOVA was performed to measure for the effect of the two training models on speed and jump variables and and a linear regression to measure the influence of body mass on the same variables. Resistance sprint training presented a significant worsening for the displacement time to the left side (p= 0.049), in addition, both groups did not obtain significant improvement in any of the other dependent variables, and body mass seems to have an influence on the displacement time. and the jump height of the athletes. Six weeks of training and an overload based on a percentage of body mass do not seem to allow for an increase in performance variables.
