*
Measures are reported as number (n) or mean and sd.
†
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.
