Lee, D.K., Lee, B.K. Effects factors and exorcise time at critical power of bicycle ergometer of primary and middle school students. Exercise Science. 12(4): 703-714, 2003. The purpose of this study were to analyze the effects factors and exorcise time at critical power of bicycle ergometer of primary and middle school students, and to provide the guidelines for the measurement of critical power. The subjects were consisted of 16 males(12.7±1.2 yrs), 19 females(13.0±1.8 yrs) on primary and middle school. The critical power were calculated by regression analysis according to the relationship among work, intensity and time after four cycle ergometer test to fatigue from 1 to 10 minute. We were measured bicycle ergometry exercise lime at CP for 30 minutes or fatigue. The main findings were as fellows; On male Primary, middle school students, CP were 7.7∼13.8% more higher than AT However, on female primary school students, AT was 4.4% more higher than CP Exorcise time at CP of male students was 22.12±7.42 minuts, that of female students was 20.08±7.20 minutes. As a results of comparison CP effects factors among exorcise time groups, the higher group of relative AT were more longer exorcise lime. On correlation analysis among exercise lime at CP and effects factors, exorcise time had a positive relationship with relative AT(W/kg), and relative average Intensity(W/kg) for CP measurement. Exorcise time had a negative relationship with CP(W), and lowest intensity(W) for CP measurement. It is concluded that CP was a little overestimate AT, but CP was useful index on aerobic power. Exorcise time at CP had a positive relationship with relative AT(W/kg), and relative average intensity(W/kg) for CP measurement, and had a negative relationship with CP(W), and lowest intensity(W) for CP measurement.
