Simultaneous measurments of energy metabolism, heart rate and bipolar surface EMG's of 17 muscles during 11 static postures were performed with ten male adults aged 20-25. Because of stabilization of EMG in all subject muscles and minimum of coefficient of variation both for energy metabolism and heart rate, the integrated EMG in half rising posture with knee bending at 90° was presumed to unit of muscle activity for each muscle. When six transformed EMG's, which are well known to antigravity muscles, were chosen predictor variables, coefficient of determination (proportion) of the multiple regression equation for energy metabolism and heart rate were 0.691 and 0.243 respectively. Selecting seven muscles for predictor variables by stepwise method, proportion for energy metabolism was 0.713 and for heart rate 0.379. Seven predictor variables of multiple regression equation for energy metabolism were M. vastus medialis, M. rectus femoris, M. gluteus maximus, M, semitendinosus, M, tibialis anterior, M, erector trunci and M. frontalis in the order their absolute value of standard partial regression coefficient. For heart rate, the following muscles were selected; 1) M. gluteus maximus 2) M, gluteus medius 3) M. masseter 4) M. tibialis anterior 5) M, vastus medialis 6) M. biceps f emoris 7) M, tranpezius.It was confirmed that muscle activities in various static postures directly reflected energy metabolism but that heart rate was not reflected in comparison with energy metabolism. Energy metabolism tended to be predicted by great antigravity muscles, while heart rate had a tendency to be predicted by muscles which are nearby main blood vessels. It was disclosed that in muscle activities the effect on heart rate differed from on energy metabolism
