Abstract

DOI: http://dx.doi.org/10.5007/1980-0037.2017v19n2p224 The aim of the study was to analyze the effect of a tapering period on anaerobic power and capacity of tae-kwon-do athletes. Thirty-one male tae-kwon-do participants of the Brazilian Championship were selected in a non-probabilistic way. Subjects were randomly divided into two groups, namely: experimental group (EG, n = 15) and control group (CG, n = 17). Both groups followed the same training protocol up to the tapering stage. CG was submitted to training loads contained in the last two weeks of the macrocycle. Only EG was submitted to tapering. Tapering had 2 weeks duration, adopting the linear tapering method. Taekwondo Anaerobic Test was performed by athletes before the start of the season, which was named as pre-intervention, and the last week of each mesocycle [Prep I, Prep II and Tapering (only EG)]. Group vs. time effect interaction (p < 0.01) was identified for alactic anaerobic power, with an increase only in EG in tapering (p = 0.01). A significant group vs. time interaction (p <0.01) was revealed to fatigue index, improved anaerobic capacity being checked in EG only after the tapering period (p = 0.01). It was concluded that two weeks of linear type tapering optimized the anaerobic power and capacity of male tae-kwon-do athletes.

Highlights

Tae-kwon-do is a combat sport characterized by a high requirement of muscular power in the actions that generate scores[1]
No significant difference was found in the comparisons between groups (EG and CG), in the pre-intervention for variables age (p = 0.23), relative body fat (p = 0.25), alactic anaerobic power (p = 0.21) and fatigue index in the Taekwondo Anaerobic Test (p = 0.26)
The present investigation had as premise to analyze the effect of a tapering period on power and anaerobic capacity of tae-kwon-do athletes

Summary

Introduction

Tae-kwon-do is a combat sport characterized by a high requirement of muscular power in the actions that generate scores[1]. Due to the intensity of effort during combat and the short interval between rounds, the tae-kwon-do athlete is required to demonstrate high anaerobic capacity. Athletes are categorized according to body mass and the combat lasts six minutes (3 rounds of 2 minutes with one minute of interval), and the athlete who reaches the highest score during this period is considered winner[2]. The athlete needs to recover adequately to increase competitive performance[4]. It should be noted, that tapering may be a good alternative to optimize the performance of athletes[5]
