Key result
40-minute exercise sessions were at least as effective as 60-minute sessions for improving exercise capacity and lipid profiles, with greater reductions in body weight and waist circumference (P<0.05).
Why the study?
Does a 40-minute exercise training session duration compared to a 60-minute duration improve exercise capacity and cardiometabolic markers in coronary artery disease patients undergoing rehabilitation?
Population
134 coronary artery disease (CAD) patients in a 7-week rehabilitation programme
Comparison
40-minute exercise training sessions vs 60-minute exercise training sessions
Design
RCT, randomized in two groups
Follow-up
7 weeks

Supports 40-min sessions as effective alternatives in CAD rehab; extends evidence for shorter protocols without compromising key outcomes.

Does a 40-minute exercise training session duration compared to a 60-minute duration improve exercise capacity and cardiometabolic markers in coronary artery disease patients undergoing rehabilitation?
p-value: p=>0.05
In early cardiac rehabilitation for CAD patients, 40-minute exercise sessions are at least as effective as 60-minute sessions, potentially reducing workload for rehabilitation centers without compromising patient outcomes.
Hansen et al. (2008) conducted an RCT in Coronary artery disease (n=134). 40-min exercise training sessions vs. 60-min exercise training sessions was evaluated on Changes in body anthropometrics, resting haemodynamics, exercise capacity, ventilatory threshold, blood plasma lipid profile, and C-reactive protein level (p=>0.05). 40-minute exercise sessions were at least as effective as 60-minute sessions for improving exercise capacity and lipid profiles, with greater reductions in body weight and waist circumference (P<0.05).
