This study was, just in case of U-healthcare time, to develop the integrating on-line exercise prescription system to diagnosis and analysis the condition of an exercise -comsumer- health as using the realtime internet on-line. The results of this system development in using JDK(Java Development Kit)-web program from window 2003 server were followed as: First, we developed this program to be possible to output it visible to measure and assess client`s welling-being. Second, we made this standard database protocol and exercise source digital contents. Third, according to client`s health condition, we developed the module to search for the optimum exercise prescription paper and to build 720 exercise prescription database field. Fourth, output form was developed to present a visible exercise prescription. Fifth, we developed the monitoring program to view all process from lasting exercise prescription management to storing measure or prescription source.

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 30˚/sec, 2. It was showed each 62.3±7.53NM(85.6±12.89%), 24.4±2.34NM(33.4±2.34%) at 120˚/sec 3. 30˚/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.

The purpose of this study was to develop a main algorithm of the IT Taekwondo mitt that can quantitatively analyze the intensity of the kicking motion in real time. To quantitatively calculate the impulse, six Taekwondon players performed the motion of striking the sensor of piezoelectricity attached to the mitt, using Isokinetic Muscle Strength (Biodex System 4). The impulses were conversely predicted with the sensor’s values of th e mitt as the Biodex’s angular velocity increased. The results indicated that the piezoelectricity value was a significant variable in predicting the impulse that has power of explanation of 99.10%. The regression equation model was proposed.
