| Research Abstract |
Muscle force is enhanced when an extra pulse is applied during an electrically evoked muscle contraction with a constant stimulation frequency ("catchlike property"). To elucidate these mechanisms, we measured the behaviors of muscle-tendon complex using ultrasound B-mode. From the results of current study, the enhancement in force induced by an extra pulse is due to an increase in muscle stiffness in humans.
