ABSTRACT

한국어 초록

유산소 운동은 호흡에 의해 조직으로 들어온 산소를 이용하여 에너지를 형성하고 그 에너지에 의해 근 수축을 일으키는 운동으로서, 유산소성 운동이 심폐기능에 미치는 주된 효과로는 최대산소섭취량의 증가, 안정시 심박수의 감소, 심박출량의 증가, 심장근의 비대, 폐활량 및 폐확산 능력의 증대가 있다. 유산소 운동시에는 직접 에너지를 형성하는 당질과 지방 등의 영양소와 산소가 충분히 공급되어 장시간 운동이 가능하게 된다(백삼현, 2006).

The purpose of this study was to examine the difference of cardiorespiratory function to the physical fitness grade of elementary school girls in a bid to lay the foundation for improving school physical education activities. The subjects in this study were 10 students who were selected by random sampling from a school sixth year girls in M elementary school. Out of them, five children are high grade in physical fitness, and the others are low grade. To assess their cardiorespiratory function, a treadmill made by Quinton in the United States was employed. As for exercise load, a gradual workout test was conducted according to KISS(re) protocol. The data were analyzed with SPSS 12.0K program, and Mann-Whitney U Signed Ranks Test was employed, which was a nonparametric test. The level of significance was set at p<.05.
There was no significant difference of oxygen intaking(VO2) between grades. There was no significant difference of oxygen intaking in a weight(VO2/kg) and METs in rest stage, stage 1, 2, 3, 4 and recovery stage, but in a stage 5, appeared significant difference. The difference of VCO2 appeared high value in the high grade in every stage, but both grades appeared no significant differences. The VE appeared no significant difference in every stage. The RER appeared in a stage 4, appeared significant difference.

※ Key Words : cardiorespiratory function, physical fitness grade
