The subjects were 18 healthy males. The continuous task on 30 times knee extension isokinetic contraction was performed by dynamometer (Biodex). And measurement of maximal torque on isometric contraction was pre and post continuous task. At the same time, the muscle activity and deformation amount at the vastus medialis obliquus (VMO) and vastus lateralis (VL) muscles were measured using the surface electromyography and MC sensor method (TMG. BMC). As a result, the continuous knee extension task reduced knee extension torque by 10％. In addition, the muscle activity at the VMO and VL higher in post than pre during the continuous knee extension task. However, the deformation amount was lower in post than in pre during the high-intensity (over the 30％MVC) torque exertion. Moreover, the significant correlations were observed between the relative values of VMO and VL muscle activity and deformation amount pre and post the continuous knee extension task, respectively. Therefore, although the evaluation methods were different, coordinated muscle activity and deformation amount between VMO and VL were confirmed., 22K11582, 1520578603916839936, application/pdf},
