The purpose of this study was to get an information on among the record of elite speed skating athletes, isokinetic ankle joint muscular and anaerobic power function during 100m, 500m and 1,000m game. This study were participated in 11 subjects who were elite speed skating athletes. It was used cybex 770 and wingate(monark). First, ankle strength and isokinetic strength showde plantar flexion, dorsiflexion each 113.8±12.4NM(per bodymass:156.7±22.04%), 41.4±4.41NM(56.7±5.93%) at 30〫 /sec, 2. It was showed each 62.3±7.53NM(85.6±12.89%), 24.4±2.34NM(33.4±2.34%) at 120〫 /sec 3. 30〫 /sec peak torque of the axis of ankle(plantar flexion, dorsiflexion), showed significant(r=-.711,-.625,-.545,-.604)at 100m, 500m. 4. Maximal and mean power were each 878.19±71.94watt(12.04±0.80%), 641.49±49.09watt(8.81±0.55%)when measured wingate for 30seconds in elite speed skating athletes. Anaerobic maximal power and 100m record showed high corelation(r=-.708, -.681)and it was similar to 1,000m and mean power(r=-.633). As a result of this study, muscular training was emphasize on ankle and anaerbic power to improve speed skating record. most of all, the appearance of klap skate need more powerful strength of lower body.
