Comparative study on isokinetic Strength of lumbar joint and a knee joint between National Alpine ski team and national reserve team

&nbsp;&nbsp;The current study aims at determining the effect of fitness and suggesting basic information necessary for training the National Alpine ski team through comparing the uniform nature lumbar joint and a knee joint muscular function in 20 Alpine ski racers based on race results. We divided the group into A (National team) and B (National reserve team) groups, and we used the result obtained by a body component analysis programs such as In Body 3.0 and Biodex system 3, which were further examined statistically by SPSS/PC+ program. The difference of uniform nature lumbar joint and a knee joint muscular function from the race in each team was analyzed through Independent Samples t-test, and the results are as follows:<BR>&nbsp;&nbsp;1. The uniform nature the absolute lumbar region of a protractor and the flexor muscular strength in National Alpine ski team was notably higher than that of National reserve team, but there was little difference in relative value per weight.<BR>&nbsp;&nbsp;2. The uniform nature of lumbar region muscular stamina of National Alpine ski team was comparatively higher than that of the reserve team, but there was little difference in rate of muscle.<BR>&nbsp;&nbsp;3. The average power of uniform lumbar region in National Alpine ski team showed a sizable difference at 60 degrees per second (p＜.0l), and at 180 degrees per second there was a sizable difference between groups (p＜.01).<BR>&nbsp;&nbsp;4. The left and right protractor of uniform nature knee joint and maximum muscular strength in National Alpine ski racers was notably high, but there was little difference in relative value per weight.<BR>&nbsp;&nbsp;5. The uniform nature left and right of protractor and muscular stamina flexor knee joint in National Apline ski racers was notably high (p＜.01), but there was little diffrence between groups in muscular stamina of the right flexor.<BR>&nbsp;&nbsp;6. The rate of muscle of uniform nature knee joint and the rate of muscle of both of National Alpine ski racers was not much different from that of National reserve team.<BR>&nbsp;&nbsp;7. The average power of the left and right protractor and the uniform nature knee joint of flexor of National Alpine ski racers at 60 degrees per second was notably high (p＜.01). However, though the average power of the left and right of protractor and the right of flexor was notably high at 180 deg per second (p＜.05) there was little difference in the left flexor.
