Development of an equipment for weight-bearing training with variable brake(ER fluid brake)

我们研究了小腿外侧前屈或劈腿蹲运动，结果表明，这些运动并没有增加膝关节的机械应力，而是增强了下肢的肌肉。为了获得更安全有效的运动训练，研制了一套配备电流变液制动器的训练系统。该系统可实现对阻力和速度的控制，并可对运动数据进行测量。对阻力腿外侧屈的运动分析表明，新训练系统的训练效果优于传统器械训练。在运动分析的基础上，改进了训练系统的速度控制性能，增加了运动数据的上报功能。

We researched resistive lateral leg reach or split squat exercises and these results demonstrated exercises didn’t increased mechanical stress in the knee joint but strengthened muscles of the lower limb. In order to obtain more safe and effectiveexercise, a training system equipped an electro-rheological fluid brake was developed. This system can control the resistance force and the speed, and measure kinetic data. The motions analysis of resistive lateral leg reach suggested that the exercise with the newtraining system was more effective than the exercise with the conventional equipment. Based on the motion analysis, we improved speed control performance of the training system and added a reporting function of kinetic data.
