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.
