This study was to find out fitness characteristics of alpine skiers based on comparative analysis of knee joint muscular functions, aerobic power and anaerobic power. Original fitness according to performance level of the national representative top ranked alpine skiers and study to make use of the finding for the purpose of upgrading alpine skiers fitness training and evaluation. The surveyed of the test include top 10 rankers of the national representative team and its canididate group of 12~15 rankings. The groups were divided into two groups: junior national team and the collegian team.Isokinetic knee joint muscular functions employed Cybex 770(Lumex Inc. USA) to measure peak torque, endurance ratio, muscular development balance ratio and average power. For measurement of aerobic power, and automatic breath gas analyzer QMC(Quinton Co. USA), Q4500 was employed to measure VO₂ max, VEmax, HRmax, R.Rmax, At, and R. For measurement of anaerobic power, Wingate anaerobic power analyzer employed. Helmas(K.O.R) was employed to inspect a basic fitness condition. According to results, the following conclusions were obtained.1. peak torque of knee joint muscular function and average power were high in the groups that attained high level of performance(p<.05).2. Average power of knee joint was large in the group who attained a higher level of performance but a significant gap could not be found.3. Flexor endurance ratio of knee joint was large in the group that attained a high level of performance. Left flexor indicated a significant gap(p<j.05). but total work among the test of flexor endurance ratio was large in many groups who attained a high level of performance and indicated a significant gap between elongate muscle(right) and flexor(left)(p<.05).4. Ispilateral balance and bilateral of knee joint did not show any difference between levels of performances but the group of high performance level had probablity of injuries(p<.05).5. In case of inspection of aerobic power, VO₂ max, R was high in the group of high performance level but a significant difference could not be found.6. In case of inspection of aerobic power, R.Rmax, VEmax, HRmax AT were all high in the group of low performance level but there was a significant difference in R.Rmax only(p<.05).7. In case of inspection of anaerobic power, the group of high performance level was high and there was significant difference in peak power, mean power and total work only(p<.05).8. In case of inspection of basic fitness condition, there appeared high in the group of high performance level. A significant change could be noted only in the arms-bending and stretching, sergeant, side step, forward bending and raissing body upward(p<.05).
