The effectiveness of the Coronary Health Improvement Project III in motivating initially sedentary female participants to increase their participation in leisure-time physical activity four months after the completion of the program

esearch has established evidence of an independent role of physical activity in the primary prevention of coronary heart disease (CHD). However, 25-60% of U.S. adults are sedentary, and prevalence of inactivity is the highest among women.
