The purpose of this study was to investigate the effects of taekwondo training on VO₂max, MVO₂ and electrocardiogram ST slope, QRS duration in college woman.
Subject were divided into two groups, one is taekwondo group (n=11) and the other is control group (n=10). They participated in graded exercise test (Balke protocol) and measured aerobic capacity and electrocardiogram. The aerobic capacity (VO₂max and AT) was measured by autogas analyser. The resting and exercise rate-pressure product (RPP) could be measured with HR and systolic BP for MVO₂ measurement. The electrocardiogram ST slope, QRS duration was calculated using automated software program (QMC). The measured data were analyzed by using paired t -test.
The results of this study were as follows : There was a significant difference of VO₂max and AT between taekwondo group and control group. VO₂max of taekwondo group was 4~5 mL/㎏/min higher than control group (p＜0.01) and AT also taekwondo group was 3.4% higher than control group (p＜0.05). There was no significant difference of maximal exercise MVO₂ between taekwondo and control group. There was no significant difference of electrocardiogram ST slope between group but rest QRS duration in taekwondo group was longer than the control group (p＜0.01).
Conclusively, these data suggest that regular taekwondo training will strengthen on aerobic capacity and resting slow heart beats.
