Brief summary
The purpose of this study was to determine the effect of lower extremity muscle activity on the increase of cardiopulmonary metabolic cost during inclined treadmill gait in the elderly.
Detailed description
The purpose of this study was to determine the effect of lower extremity muscle activity on the increase of cardiopulmonary metabolic cost during inclined treadmill gait in the elderly. Metabolic energy expenditure and muscle activity are measured simultaneously.
Interventions
OTHERInclined 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)
