About

Apparently healthy and well-functioning community dwelling 70-80 year-olds will be recruited to the study. All subjects undergo pre-screening for suitability and a physicians examination, as well as 7-day habitual daily steps are measured to ascertain baseline physical activity. Half of the recruited subjects (n=40) will be randomized into the intervention group and half (n=40) randomized into the control group. The intervention group is then required to reduce their daily steps to <2000 for a 2-week period. Thereafter, the intervention group participates to a 4-week strength+endurance training rehabilitation program and no longer has restricted daily step count. The control group continues their normal habitual physical activity level throughout the 6-week study period.
