The aim of the investigation was to study the course of the isokinetic parameters--peak torque, time range of tension development and fatigue index--in an age range from 13 to 19 years and to compare the results with those of competitive athletes of the same age specifically trained in running. For this purpose measurements of the flexors and extensors in the upper ankle joint, knee and hip were taken. The average for the six muscle groups correlated significantly in all three parameters not only with the age development but also with the degree of training. The individual muscle groups, however, differed widely. An increased frequency of injuries by certain ratios of peak torques between flexors and extensors was not found. Instead already in the physiological age development occurred relations that were connected with an increased frequency of injuries. Prospectively this suggests that the time range of tension development has additional influence here.
该研究的目的是研究13至19岁年龄段等速参数（峰值扭矩、张力发展的时间范围和疲劳指数）的变化过程，并将结果与经过专门跑步训练的同年龄竞技运动员的结果进行比较。为此，对上踝关节、膝关节和髋关节的屈肌和伸肌进行了测量。六个肌肉群的平均值在所有三个参数上不仅与年龄发展显著相关，而且与训练程度显著相关。然而，各个肌肉群差异很大。未发现屈肌和伸肌之间特定峰值扭矩比导致的受伤频率增加。相反，在生理年龄发展过程中就出现了与受伤频率增加相关的关系。前瞻性地看，这表明张力发展的时间范围在此处有额外影响。
