The effect of Taekwondo training periods on body composition, muscle strength and maximal oxygen consumption in child

  The purpose of this study was to investigate the difference of body composition, muscle strength and VO₂max according to the Taekwondo training periods. Our participants in the study consisted of twenty-four elementary school student(11yrs). They were separated into three groups a control group(n=8), a 8month taekwondo training group(n=10) and a 15month Taekwondo training group(n=8). We found that %fat was significantly difference between control and Taekwondo training group, also, lowest 15 month group. And muscle strength and VO₂max were high in the Taekwondo training group compared to the control group, but blood pressure was no significant difference among group. Especially VO₂max/weight was highest 15 month group. In conclusion, Taekwondo training was shown to positive influence on body composition, muscle strength and cardiorespiratory function in elementary school student. However, growing adolescents needed long-term Taekwondo training to improve their body composition and physical fitness.
