This study investigated the optimum diameter of wheelchair hand rim and EMG response during long time exercise. Tested hand rim diameters were 16mm, 22mm, 32mm and 42mm. The optimum hand rim diameters evaluated as most easy to operate were 32mm and 42mm. Wheelchair exercise was performed on treadmill, and loaded slope were 0%, and exercise time was 30min. During wheelchair exercise with the optimum hand rim diameter, RPE and HR were lower than those for the hand rim with the diameter of 16mm. The agonist muscles were deltoideus and trapezius in all hand rim diameters, and the changes of IEMG during exercise were not difference between each hand rim diameter. We consider that the long time exercise of wheelchair with the optimum hand rim diameter might cause less fatigue and exert muscle force more easily.
