Physical activity (PA) is often quantified with step counts using pedometers. Few studies, however, have examined the use of pedometers to quantify an increase in physical activity following an exercise intervention in older women. The purpose of the present study was to examine changes in cardiovascular function and activities of daily living (ADLs) following an intervention designed to increase daily physical activity 2,000 steps/day. Modestly active women volunteered to participate in this study and were assigned to either an intervention group (E = 20) or control (C = 10). Cardiovascular function was assessed using the six-minute walk test (6MWT), while ADLs were assessed with a chair stand test and the up and go test. The E group increased step count about 1,300/week at the end of the eight-week experimental period and increased cardiovascular function (6MWT) 3.4%. While the modest intervention employed presently achieved only 93% of its target goal to improve physical activity, the increased daily step counts led to an increase in cardiovascular function. Collectively, the results indicate that the modest intervention to encourage increased PA in older women is beneficial to improving cardiovascular health.
