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.

Conditions

Gait

Keywords

Muscle activity; Cardiopulmonary metabolic cost

Outcome Measures

Primary Outcomes (1)

• Change on metabolic energy expenditure

  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)

  1 hour

Secondary Outcomes (1)

• Change on muscle activity

  1 hour

Study Arms (1)

Inclined treadmill gait

EXPERIMENTAL

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

Interventions

Eligibility Criteria

• Age: 65 Years - 84 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Older Adult (65+)

You may qualify if:

• Between 65 and 84 years elderly without neurological effects
• Ability to independent gait at least 16% inclined treadmill
• High levels of physical performance (SPPB \> 7)

You may not qualify if:

• Severe visual impairment or dizziness that increases the risk of falls

• Difficult to understand experimental tasks because of extremely severe cognitive impairment
• Recent acute injuries such as fractures within 6 months, or experience in orthopedic surgery such as artificial joint replacement
• Acute injuries such as fractures within 6 months or orthopedic surgery such as artificial joint replacement
