Not Applicable

Completed

• Conditions: Gait
• Interventions: Other: Inclined treadmill gait

• Registration Number: NCT04614857
• Lead Sponsor: Samsung Medical Center

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.

Arm && Interventions

Group	Intervention	Description
Inclined treadmill gait	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)

Primary Outcome Measures

Name	Time	Method
Change on metabolic energy expenditure	1 hour	All subjects underwent measurements 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)

Secondary Outcome Measures

Name	Time	Method
Change on muscle activity	1 hour	All subjects underwent measurements of muscle activity 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)
