Why the study?
Does higher physical activity reduce the presence and extent of calcified coronary atherosclerosis in asymptomatic adults?
Population
630 consecutive asymptomatic men and women ages 39-45 without known heart disease
Comparison
Physical activity vs Different levels of physical activity
Design
Cross-sectional

No link between activity and coronary calcium; leaves open alternative mechanisms for benefits in asymptomatic adults.
Does higher physical activity reduce the presence and extent of calcified coronary atherosclerosis in asymptomatic adults?
Physical activity improves cardiovascular risk factors but is not associated with a reduction in coronary calcification, suggesting its benefits are mediated through other mechanisms.
Taylor et al. (2002) studied this question.
