Outcomes
Primary Outcomes
endurance
Time Frame: 12 weeks
assessed by the long-distance corridor walk
physical function
Time Frame: 12 weeks
assessed by standing balance, gait speed, and chair stands

Time Frame: 12 weeks
assessed by accelerometry and the Physical Activity Scale for the Elderly
life-space mobility
Time Frame: 12 weeks
assessed by life-space mobility questionnaire
energy cost of walking
Time Frame: 12 weeks
