Table 3 Coefficients (95% Confidence Interval) for the Linear Regression of SF-36 Scales in 2009 on Compliance in 2003 with Recommendations on Leisure-Time Physical Activity (LTPA) from the American College of Sports Medicine and the American Heart Association (ACSM-AHA).

From: Longitudinal association of physical activity and sedentary behavior during leisure time with health-related quality of life in community-dwelling older adults
