Abstract
The objective of this study is to clarify whether load of a muscle strengthening device for quadriceps muscle of thigh differs according to the exercise speed and individuals during extension-flexion exercise of knee joint. The device was developed in order that the load and changes in degree were introduced to Kin-Com during exercises. Twenty healthy female students performed 13 extension-flexion exercises of knee joint at 4 different speeds. All values of load were significantly different(p<0.01) among 4 speeds and individuals. The results indicate that load on a stress pad of the muscle strengthening device for quadriceps muscle of thigh differs according to exercise speed and individuals during extension-flexion exercise of knee joint.
