The Effect of Taekwondo Training on Aerobic Capacity, MVO2, ST Slope and QRS Duration / 체질인류학회지

ABSTRACT

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/kg/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.
