Exercícios na borracha by Elton Fiebig

Creio que todos do judô conheçam o Elton. Aqui vocês podem acompanhá-lo demonstrando exercícios de condicionamento físico na borracha.

Embora não tenha conhecimento de estudos sobre esse treinamento no judô, resultados de outros estudos apontam para benefício na velocidade de execução. O resumo abaixo mostra resultados positivos na velocidade do chute no taekwondo.

In the Olympic sport of Taekwondo (TKD), elastic resistance training (ERT) is often used with the aim of improving kicking performance; however, the efficacy of this has never been examined experimentally. The purpose of this study was to investigate the effect of a TKD-specific, progressive ERT protocol on the velocity of the TKD turning kick. Twelve TKD athletes were randomly allocated to receive either a 4-week intervention of ERT plus usual TKD training (n = 6) or to a control group receiving 4 weeks of usual TKD training only. Kicking velocity from initiation to impact on a target was measured pre- and postintervention using a digital timer and two pressure switches. Kicking velocity improved significantly (by 7%) in the ERT group, whereas there was no improvement in the control group (p < 0.05). These data suggest that ERT is a feasible means of sport-specific resistance training for TKD and that TKD performance could benefit from an improved velocity of the attacking turning kick.
