이 연구는 장기간의 태권도 수련이 최대산소섭취능력(maximal O2 uptake, VO2max)과 무산소성역 치(anaerobic threshold, AT), 심근산소소비량(myocardial oxygen uptake, MVO2), 심전도상 V5 ST분절 및 QRS간격 에 어떠한 영향을 미치는지를 규명하는 데 있다. 이를 위해 태권도를 5년 이상 규칙적으로 수련해 온 대학교 여자 태권도선수(11명)와 체육학과 여자 비선수(10명)를 대상으로 운동부하 검사(balke protocol)를 실시하여 이들 두 집단 간 최대산소섭취량과 무산소성역치수준, 심전도를 통한 ST분절과 QRS간격을 동시에 분석하였다. 측정된 자 료는 평균과 표준편차로 나타냈으며 또한 대응표본 t -test로 유의성 검사를 하였다. 그 결과 최대산소섭취량은 태 권도선수집단이 대조집단에 비해 높게 나타났으며(p⁄0.01), 무산소성역치수준도 태권도선수집단이 유의하게 높 게 나타났다(p⁄0.05). 안정시 및 최대운동시 심근산소소비량은 두 집단 간 통계적인 차이가 없었다. 심전도 ST분 절의 경우는 두 집단 간 차이가 발견되지 않았으나, 안정시 QRS간격은 태권도선수집단에서 유의하게 길게 나타 났다(p⁄0.01). 결론적으로, 규칙적인 태권도 수련은 유산소성 능력을 강화시켜주고 안정시 심박수의 감소를 가져 오는 것으로 사료된다.

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.
