플레이포트 놀이가 생리학적 효과에 미치는 영향 = Physiological effect of playfort play in children

다국어 초록 (Multilingual Abstract)

To validify the physiologic availability of the playport game, we examined the metabolic and ventilatory responses of second and fourth grade boys(n=6) and adult men(n=4) during playport games. In children, maximal oxygen uptake(V˙O_2max) and lactate threshold(V˙O_2 LT) measured on treadmill, averaged 47.3±3.4 ml·㎏^1·min^1 and 27.6±1.9 ml·㎏^1·min^1, respectively. The playing at the 8 min playport elicited an average of 44.1±5.2 ml·㎏^1·min^1 during the last 4 min after starting the play, which corresponded to approximately 90% of V˙O_2max. When compares the lactate (La) levels between children and adults, the children has significantly lowered La at 2.44±0.6 mM/ l and below than the adult groups. The present results suggested that children experience high intensity physical activity during playport game seemingly contributed to the enhancement of cardiorespiratory function.
