Sixteen healthy adults (10 males and 6 females, average age; 22.8 ± 4.0 years) performed a treadmill walking with axillary crutches and a pick up walker, and their oxygen consumption, transfer efficiency, walking rate, and anaerobic threshold (AT) were measured during each walking. The speeds of the walking with axillary crutches and a pick up walker were 50% and 70% of that of a comfortable treadmill walking. Oxygen consumption during the walking with axillary crutches or a pick up walker was higher than during a comfortable treadmill walking, exceeding AT value except during the walking with axillary crutches at the speed of 50% of a comfortable treadmill walking. Transfer efficiency of the walking with a pick up walker was lower than that with axillary crutches, and walking rate of the walking with a pick up walker was higher than that with axillary crutches. This suggests that walking rate plays a role in inducing higher oxygen consumption during a treadmill walking with a pick up walker, compared with the walking with axillary crutches. These results were considered applicable to the exercise prescription aiming at physical strengthening for persons with lower limb disabilities, and to risk management for the patients with cardiovascular disorders.
