Effects of Balance chair on body function for the change in Heart rate and surface electromyogram (M.tibialis anterior, M, vastus medialis, M. vastus lateralis, and Mm. dorsi proprii) . Muscular fatigue of lower limb of three adult subjects (Body weight 65.0±14.1kg , Body height 168.6±2.3cm age 21.6±1.1 years old) in sustained sitting hosture for ninety minutes is experimentaly studied to evaluate effective index for static muscular movement. The following results were observed. Given the many body hostures assumed during any sitting period, in addition to the muscular activity involved even when the body seems to the at rest, sitting is not the static type of activity it frequently in conceived. Balance chair : Changes of Heart rate significantly increased (P<0.05 ) and Mm, dorsi proprii discharge on EMG. Arrow chair : Changes of Heart rate not significantly and M, vastus medialis and Mm, dorsi proprii discharge on EMG. Classic arm chair : Changes of Heart rate not significantly and Mm. dorsi proprii discharge on EMG. High back chair : Changes of Heart rate not signicantly and M, vastus medialis and Mm, dorsi proprii discharge on EMG. High mirror chair : Changes of Heart rate not significantly and M, tibialis anterior and Mm, dorsi proprii discharge on EMG. Red and Blue chair : Changes of Heart rate not significantly and M, vastus medialis and Mm, dorsi proprii discharge on EMG.
