Over 98% of older women do not meet national guidelines for physical activity (PA). There is clear evidence that a physically active lifestyle reduces the human and economic cost of heart disease in a dose-response relationship; but current efforts to increase long-term PA in older women are inadequate. The aims of this proposed research are to: 1) determine the feasibility of using an individually tailored motivational counseling intervention method to promote lifestyle physical activity (LPA) in older sedentary women; 2) examine intervention effects by comparing baseline to outcome measures at 3 and 6 months in treatment and information/attention comparison groups; and 3) explore stage of behavior change and self-efficacy and their relationship to LPA, along with functional health.
