The purpose of this study was to examine the validity of estimated muscular tension using the musculoskeletal model during forward lunge and squat. Eighteen healthy men were enrolled in this study. A correlation coefficient was calculated between the estimated value for the muscular tension and the root mean square (RMS) value for the electromyographic recordings. Electromyographic data was obtained from vasti medialis (VM) and lateralis (VL) and rectus femoris (RF). The mean values of coefficient correlation for VM and VL exceeded 0.61 during the flexion and extension phase of forward lunge. The coefficient correlation for squat fell below 0.44 for during the flexion and extension phase, and RF, it fell below 0.30 during forward lunge and squat. Similarities of the waveform patterns exceeded 0.93 between estimated muscular tension and electromyographic RMS for both forward lunge and squat. The value of the estimated muscular tension for RF for both exercises was found to be very small. In conclusion, the output pattern for the estimated muscular tension was validated, although further study is required to examine the value of muscular tension, in particularly, of a two-joint muscle such as RF.
