Alpine skiers require both aerobic and anaerobic capacity particularly for knee extension and flexion muscle strength. As for most all athletes, lactic acid removal is of utmost importance. In past studies, athletes from various disciplines have had their anaerobic power test measured using the power max VⅡ, but these studies were limited to only three parameters: body weight per peak power(watt/kg);peak revolution(rpm);and peak weight load(kp).However, the data generated was not very useful for elucidating discipline specific characteristics. With that in mind, we felt it necessary to search for more meaningful parameters that could possibly distinguish between speed and strength type muscle power and their relative contributions for peak performance in a range of disciplines. We studied such parameters in alpine skiers and found that they do indeed provide extremely useful data that can be used to better fine tune their training regimen. This study consisted of 97 subjects in three categories: ALP; 32 alpine skiers, XC; 39 cross-country skiers, and a control group of 28 fit but not athletically competitive adults. The average max power outputs for each group were as follows: ALP group 14.8±1.5watt, XC group 13.9±1.4watt, CONT group 13.1±1.5; anoxia values for the power tests anoxia characteristics are not shown as the results are obvious(ALP>XC>CONT). The observed strength to speed ratios varied significantly among the three groups: ALP>XC>CONT, with only the CONT ratio being below 1. This suggests that for alpine skiers the best training regimen should focus heavily on developing power in strength type muscles.
