*
All measures are reported as number (n) or mean and sd. Variables with significant differences between groups are in bold.
†
Significant difference between the intervention and control groups (P < 0·01).
‡
Leg extensions are counted for different durations and using different ankle weights between participants. Mean values should be interpreted carefully.
§
Physical activity was measured by the Community Healthy Activities Model Program for Seniors questionnaire.
**
HR QoL was measured by the SF-36 questionnaire.
