About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • 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)

Exclusion criteria

  • Severe visual impairment or dizziness that increases the risk of falls
  • Serious cardiac conditions (hospitalization for myocardial infarction or heart surgery, history of congestive heart failure, documentedserious and unstable cardiac arrhythmias, hypertrophic cardiomyopathy,severe aortic stenosis, angina or dyspnea at rest or during activities ofdaily living)
  • 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

Treatment and study plan

Inclined treadmill gait

Other

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 outcomes

  1. Change on metabolic energy expenditure

    Time frame: 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 outcomes

  1. Change on muscle activity

    Time frame: 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)
