A Study on the isometric muscle power of ballet-major women college students

&nbsp;&nbsp;It has reached the results as follows to measure the isometric muscle power on 42 ballet-major women college students and 42 general college women inorder to find the isometric muscle power of the ballet-major students.<BR>&nbsp;&nbsp;1) The peak torque of the average femoral flexors of ballet-major women college students was found to be 37.7±7.70 in 60°ㆍS？¹ of angular velocity, to be 30.29±6.52 in 180°ㆍS？¹ ,and 23.39±8.06 in 300°ㆍS？¹. In the case of the femoral extensors, the one was shown to be 71.86±9.44 in 60°ㆍS？¹, to be 78.29± 10.44 in 180°ㆍS？¹, and 39.86±8.78 in 300°ㆍS？¹.<BR>&nbsp;&nbsp;2) For general women-college students, the peak torque of the average frmoral flexors was found to be 38.1±6.31 in 60°ㆍS？¹ of angular velocity, to be 28.00±5.51 in 180°ㆍS？¹, and 21.86±5.43 in 300°ㆍS？¹, high-speed angular velocity. The femoral extensors was 78.29±10.44 in 60°ㆍS？¹, to be 51.14±7.97 in 180°ㆍS？¹, and 36.86±8.78 in 300°ㆍS？¹.<BR>&nbsp;&nbsp;3) The meaningfulness on the isometric femoral flexors of 60°ㆍS？¹ (P＞0.64), 180°ㆍS？¹ (P＞0.69), and 300°ㆍS？¹ (P＞0.36), and In the femoral extensors, the one was 60°ㆍS？¹ (p＞0.81), 180°ㆍS？¹ (p＞0.49), and 300°ㆍS？¹ (P＞0.61), there was no statistical meaningfulness, either.<BR>&nbsp;&nbsp;4) In connection with % body weight, the peak torque of the isometric femoral flexors of ballet-major women college students was found to be 34.29±7.13 in 60°ㆍS？¹ of angular velocity, to he 27.43±6.37 in 180°ㆍS？¹, and 21.14±7.84 in 300°ㆍS？¹, while in the femoral extensors 60°ㆍS？¹ of angular velocity was 65.57±9.95, 180°ㆍS？¹ was 45.29±7.97, and 36.86±8.78 300°ㆍS？¹.<BR>&nbsp;&nbsp;5) The femoral flexors of % peak torque of general women college students was found to be 33.57±3.87 in 60°ㆍS？¹ of angular velocity, 24.71±4.07 in 180°ㆍS？¹, and 19.14±4.81 in 300°ㆍS？¹. The femoral extensors resulted in 69.71±7.25 in 60°ㆍS？¹, 45.29±6.05 in 180°ㆍS？¹， and 35.１4±7.27 in 300°ㆍS？¹.<BR>&nbsp;&nbsp;6) In connection with % body weight, the statistical meaningfulness of the isometric femoral flexors was found to be 60°ㆍS？¹ of angular velocity(P＞0.16), 180°ㆍS？¹ (P＞0.29), 300°ㆍS？¹(P＞0.25), and there was no it. The femoral extensors was 60°ㆍS？¹ of angular velocity(P＞0.46), 180°ㆍS？¹ (p＞0.97), and 30°ㆍS？¹(P＞0.80), there was no statistical meaningfulness, either.<BR>&nbsp;&nbsp;7) In case of ballet-major women college students, the ratio between the femoral flexors and extensors showed 50% of range in 60°ㆍS？¹, 61% in 180°ㆍS？¹ and 66% in 300°ㆍS？¹, while in case of general college women it showed 49% in 60°ㆍS？¹, 55% in 180°ㆍS？¹ and 55% in 300°ㆍS？¹.
