the aim of the study was to measure the heart rate recovery, blood lactate and movement acceleration during simulated taekwondo competition.
twelve male subjects who belong to the national team, with at least five years of experience participated in this research. They performed a simulated combat to evaluate the following variables: (i) Blood lactate after one minute recovery between each round, (ii) Heart rate recovery (HRR) at thirty and sixty seconds in each minute rest between rounds, (iii) Peak acceleration (ACCp) in each round performed. The significance level was set at p < 005.
the results showed no significant differences between winners and losers in the HRR at both, thirty and sixty seconds (p > 0.05), blood lactate (p > 0.05), peak acceleration (p > 0.05) and the average acceleration of combat (p = 0.18). There was no correlation between delta lactate and ACCp (r = 0.01; p = 0.93), delta lactate and HRR (r = -0.23; p = 0.18), and ACCp and HRR (r = 0.003; p = 0.98).
these data suggest that studied variables would not be decisive in the simulated combat outcomes. Other factors such as technical-tactical or psychological variables could have a significant impact on athletic performance.
本研究旨在测量模拟跆拳道比赛期间的心率恢复、血乳酸和运动加速度。
12名属于国家队且至少有五年经验的男性受试者参与了本研究。他们进行了一场模拟战斗以评估以下变量：（i）每轮休息一分钟后的血乳酸，（ii）每轮休息期间第30秒和第60秒的心率恢复（HRR），（iii）每轮执行中的峰值加速度（ACCp）。显著性水平设定为p < 0.05。
结果显示，在第30秒和第60秒的心率恢复（p > 0.05）、血乳酸（p > 0.05）、峰值加速度（p > 0.05）以及战斗平均加速度（p = 0.18）方面，胜者和败者之间均无显著差异。血乳酸变化量与ACCp之间（r = 0.01；p = 0.93）、血乳酸变化量与HRR之间（r = -0.23；p = 0.18）以及ACCp与HRR之间（r = 0.003；p = 0.98）均无相关性。
这些数据表明，所研究的变量在模拟战斗结果中并非决定性因素。其他因素，如技术战术或心理变量，可能对运动表现有重大影响。
