*Study conducted as part of thesis submitted by R.D.C. in partial fulfillment of the requirements for the degree of Master of Science. The purpose of this investigation was to evaluate isokinetic characteristics of the knee in female, ballet and modern, professional and university dancers in order to evaluate possible differences among the groups. A total of 37 dancers with a mean age of 24.9 years was tested using a Cybex II dynamometer. A multiple analysis of variance (MANOVA) indicated that the ballet dancers had significantly higher H/Q ratios than modern dancers at three speeds (p < 0.024). Post hoc procedures indicated that the professional ballet dancers (PB) had significantly higher H/Q ratios than all other groups at 180 degrees /sec (p < 0.05). Also, although most of these dancers demonstrated normal peak torque/body weight values for knee extension and flexion, specific weaknesses were observed in the force decay rate of the quadriceps curves. It was concluded that these theatrical dancers were not a homogeneous group in terms of certain isokinetic characteristics.J Orthop Sports Phys Ther 1988;9(12):410-418.
这项研究是 R.D.C. 提交的论文的一部分，该论文是为满足理学硕士学位要求而完成的。本研究的目的是评估女性、芭蕾和现代、专业和大学舞蹈演员的膝关节等速特征，以评估组间可能存在的差异。共有 37 名平均年龄为 24.9 岁的舞者接受了 Cybex II 测力计的测试。多元方差分析（MANOVA）表明，在三种速度下，芭蕾舞演员的 H/Q 比值明显高于现代舞演员（p < 0.024）。事后程序表明，专业芭蕾舞演员（PB）在 180 度/秒时的 H/Q 比值明显高于所有其他组（p < 0.05）。此外，尽管这些舞者的大多数膝关节伸展和弯曲的峰值扭矩/体重值都在正常范围内，但在股四头肌曲线的力衰减率方面观察到了特定的弱点。研究结论是，这些戏剧舞蹈演员在某些等速特征方面并不是一个同质群体。《矫形与运动物理治疗杂志》1988 年；9（12）：410-418。
