Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Inclined treadmill gait
All subjects underwent measurements of muscle activity and respiratory metabolism energy during treadmill walking at a comfortable speed for 5 minutes and measured by three conditions (#0% inclined treadmill gait, #10% inclined treadmill gait, and #16% inclined treadmill gait)
Other: Inclined treadmill gait
All subjects underwent measurements of muscle activity and respiratory metabolism energy during treadmill walking at a comfortable speed for 5 minutes and measured by three conditions (#0% inclined treadmill gait, #10% inclined treadmill gait, and #16% inclined treadmill gait)
