This study was undertaken to determine isokinetic plantarflexion strength at various speeds and positions on a Cybex II+ dynamometer. A second purpose of this study was to identify any relationship between calf circumference and strength. Speeds used were 0, 30, and 180 degrees /sec. Positions used were supine with 0 degrees knee extension, supine with 90 degrees knee flexion, and prone with 0 degrees knee extension. Speeds and positions are randomly ordered. Nineteen female subjects were classified as either trained (N = 9) or untrained (N = 10). Plantarflexion strength was greatest in the supine position with 0 degrees knee extension in each of the three speeds tested. The results of a two-way repeated measures analysis of variance test were significant across all speeds occurring only with the trained group at a speed of 0 degrees /sec. Further comparisons of position with other speeds were not significant. Since plantarflexion torques were higher in the supine position with 0 degrees knee extension with a speed of 30 degrees /sec, clinicians might want to use this position and speed to test ankle plantarflexion torque. The relationship between calf circumference and torque was not significant. J Orthop Sports Phys Ther 1990;12(4):153-156.
本研究旨在确定在 Cybex II+测力计上以不同速度和位置进行等速跖屈力量。本研究的第二个目的是确定小腿围和力量之间是否存在任何关系。使用的速度分别为 0、30 和 180 度/秒。使用的位置分别为仰卧位，膝关节伸展 0 度；仰卧位，膝关节屈曲 90 度；以及俯卧位，膝关节伸展 0 度。速度和位置随机排列。19 名女性受试者分为训练有素组（N=9）和未训练组（N=10）。在三种测试速度中，在仰卧位且膝关节伸展 0 度时，跖屈力量最大。在速度为 0 度/秒的情况下，进行了两次重复测量方差分析的结果在所有速度上均具有统计学意义，且仅在训练组中发生。进一步比较其他速度与位置的关系没有统计学意义。由于在 30 度/秒的速度下，仰卧位且膝关节伸展 0 度时的跖屈扭矩更高，因此临床医生可能希望使用此位置和速度来测试踝关节跖屈扭矩。小腿围和扭矩之间的关系没有统计学意义。J Orthop Sports Phys Ther 1990;12(4):153-156.
