High mobility of elastic glove and sleeve have been demonstrated. If mobility is high, internal pressure of extravehicular activity (EVA) suit does not have to be low like current U.S. EVA suit. In the present study, we developed and examined physiological effects i.e., range of motion (ROM) and electromyography (EMG) of the sleeves. of the elastic sleeve with pressure differential of 0.58 atm, which is the least pressure of no-prebreathing before EVA. The effects were also compared to those of a non-elastic glove, which simulated the current EVA suit used in the U.S.A with 0.3 atm. No significant difference in ROM of the middle finger joint and EMG amplitude during grip was observed between elastic sleeve of 0.58 atm and non-elastic sleeve of 0.3 atm. However, EMG amplitude during elbow flexion with elastic sleeve was significantly larger than that with non-elastic sleeve. Thus, elastic glove of 0.58 atm can move similarly to ,non-elastic glove of 0.3 atm, but another concept is needed for the elbow joint.
