Knee joint of modern dancer is very important part of human body for displaying performance based on leg muscular strength. Because irregular practice, insufficient warming-up, unplanned practice causes various type of injury and pain, I would like to help that dancers can perform perfect dancing without any injury with CYBEX NORM <SUP>TM</SUP> uniform velocity muscular strength log.
Objects of the study has been limited for modern dancing specialists who have no disease history regarding lower parts of body and no exercise limits. Two groups which I compared is as follows. One group, I studied 10 of modern dancing specialists aged around 20 who have been performed dancing for 4 years and studying at women"s university without disease history on lower parts of body(specially on articulation). On the other group, I measured 10 women"s university students who have never learned dancing before.
I measured form measuring(standing height, body weight) with Martin"s bio measuring machine and the scales adopting Barry L. Johnson and Nelson"s methodology. I had a surveyor measuring the form measuring of all the objects for getting accurate results. Also, I measured a flexor strength and a protractor strength using CYBEX NORM <SUP>TM</SUP> which is CYBEX"s uniform velocity muscular strength log made in USA.
1. In the maximum power efficiency of knee joint and the maximum power rate per weight, as the angular velocity increase to high(180°/sec) from low (60°/sec), The contractive constriction and expansive constriction were all decreased a little. But there was no significant.
difference among them. The power efficiency was higher at the flexor than the protractor and the contractive constriction than expansive one.
At the comparison on right and left, although there was no meaningful difference, generally it was higher at the right than the left, and the modern dancer than ordinary persons.
2. When the maximum power efficiency of knee joint was revealed, as the angular velocity increased to high(180°/sec) from low(60°/sec), contractive constriction and expansive one are all increased at the flexor, and it decreased at the protractor. The strength took place at the angle at which the protractor and the expansive constriction were more extened rather than the flexor and the contractive constriction. It is viewed as a characteristic of the comprehensive actions of modern dancing that modern dancing specialist shows maximum power at the direction of the flexor"s expansion.
3. In the total of work and the total of work per weight, as the angular velocity increased to high(180°/sec) from low(60°/sec), contractive constriction and expansive one were all decreased, and the total was high at the protractor and the expansive constriction than the flexor and contractive constriction.
Significant different between the contractive constriction and the expansive constriction was appeared as the contractive constriction was higher than expansive one(P<.001).
4. In the mean power and the mean power per weight, as the angular velocity increased to high(180°/sec) from low(60°/sec), contractive constriction and expansive one were all increased, and the mean power was high at the protractor and the expansive constriction than the flexor and contractive constriction.
In the comparisons on the left and right and on modern dancing specialist the significant difference is about (p<.001), the modern dance specialist side was higher.
5. In the total work of knee joint and the total work per weight, as the angular velocity increased to high(180°/sec) from low(60°/sec), contractive constriction and expansive one were all decreased, and the total of work was high at the protractor and the expansive constriction than
