The purpose of this study was to evaluate isokinetic strength measurement in ankle joint. The study was divided into three parts. A comparison of dorsal and plantar flexion with and without consideration to the biomechanical circumstances was done. The series comprised 15 men and 10 women. A comparison of strength measurements of dorsal flexion with and without fixation of the upper trunk. The series consisted of 10 men. A reference series for dorsal and plantar flexion comprising 15 men (mean age = 34 +/- 9 yr) was used for comparison. Strength was tested at 0 degree, 15 degrees, 30 degrees, 60 degrees, 120 degrees, 180, and 240 degrees/s. The readings made without biomechanical adjustment were significantly higher than connected readings. Mean difference at 30 degrees/s was 8.4 +/- 7.1 Nm for dorsal flexion and 18 +/- 3.1 Nm for plantar flexion. The torque values were significantly higher when the upper trunk was not immobilized, and higher standard deviations were obtained. The left (viz. dominant) leg produced significantly higher muscle torque at all velocities for plantar flexors and at all but 180 degrees and 240 degrees/s for dorsal flexors. The regression coefficient was used as a measure of peak torque velocity relation, the coefficient was -0.50 +/- 0.16 for plantar flexion and -0.22 +/- 0.06 for dorsal flexion.
本研究的目的是评估踝关节等速肌力测量。该研究分为三个部分。对考虑和不考虑生物力学情况时的背屈和跖屈进行了比较。该系列包括15名男性和10名女性。对固定和不固定上躯干时的背屈力量测量进行了比较。该系列由10名男性组成。使用一个包括15名男性（平均年龄=34±9岁）的背屈和跖屈参考系列进行比较。在0度、15度、30度、60度、120度、180度和240度/秒的速度下测试力量。未进行生物力学调整时的读数显著高于相关读数。在30度/秒时，背屈的平均差异为8.4±7.1牛米，跖屈为18±3.1牛米。当上躯干未固定时，扭矩值显著更高，且获得了更高的标准差。左腿（即优势腿）在所有速度下，跖屈肌产生的肌肉扭矩显著更高，背屈肌在除180度和240度/秒外的所有速度下产生的肌肉扭矩显著更高。回归系数用作峰值扭矩与速度关系的度量，跖屈的系数为-0.50±0.16，背屈的系数为-0.22±0.06。
