Key result
Sedentary time among recent cardiac rehabilitation graduates averaged 8 hours/day and was significantly associated with lower log VO2peak (β = -0.02, p=0.001) and higher body mass index (p=0.02).
Why the study?
Is objectively measured sedentary time associated with markers of cardiometabolic health and fitness in recent cardiac rehabilitation graduates?
Population
263 recent cardiac rehabilitation graduates (~10 days post-CR), mean age 63.6 ± 9.3 years, 75% male.
Design
Cross-sectional

Sedentary time after cardiac rehab may link to poorer fitness; hypothesis-generating for interventional trials before practice change.

Is objectively measured sedentary time associated with markers of cardiometabolic health and fitness in recent cardiac rehabilitation graduates?
Effect estimate: β = -0.02
p-value: p=0.001
Even among recent cardiac rehabilitation graduates, sedentary time averages 8 hours/day and is independently associated with poorer cardiorespiratory fitness and higher BMI.
Prince et al. (2015) conducted a cross-sectional in Coronary artery disease post-cardiac rehabilitation (n=263). Sedentary time was evaluated on log VO2peak (β = -0.02, p=0.001). Sedentary time among recent cardiac rehabilitation graduates averaged 8 hours/day and was significantly associated with lower log VO2peak (β = -0.02, p=0.001) and higher body mass index (p=0.02).
