Outcome Measures

Primary Outcomes (6)

  • energy cost of walking

    assessed by oxygen consumption during treadmill and overground walking

    12 weeks

  • fatigue and fatigability

    assessed by questionnaire, rated perceived exertion during walking, and decrements in walking performance over time.

    12 weeks

  • daily activity

    assessed by accelerometry and the Physical Activity Scale for the Elderly

    12 weeks

  • life-space mobility

    assessed by life-space mobility questionnaire

    12 weeks

  • endurance

    assessed by the long-distance corridor walk

    12 weeks

  • physical function

    assessed by standing balance, gait speed, and chair stands

    12 weeks

Interventions

Timing and CoordinationBEHAVIORAL

This intervention is based on progressively difficult stepping and walking patterns that promote the timing and coordination of stepping within the gait cycle. Small-group 60-minute classes twice weekly for 12 weeks.

Timing and Coordination
Aerobic WalkingBEHAVIORAL

Outdoor walking with progressive increases in exercise intensity. Small-group 60-minute classes twice weekly for 12 weeks.

Aerobic Walking
Stretching and RelaxationBEHAVIORAL

Full-body stretching, range-of-motion exercises, and relaxation techniques. No specific gait training. Small-group 60-minute classes twice weekly for 12 weeks.

Stretching and Relaxation

Eligibility Criteria

Healthy VolunteersYes
Age GroupsOlder Adult (65+)

You may qualify if:

  • Men and women who live in the lower mainland (greater Vancouver) area of British Columbia
  • Aged 65 years or older
  • Living independently in their own home
  • Report mobility limitation, defined as any difficulty walking one-quarter mile (about 2-3 blocks) outside on level ground or climbing one flight of stairs (about 10 steps) without resting because of a health or physical problem

You may not qualify if:
