The Claim
High-intensity interval training produces greater improvements in VO₂ max and resting heart rate compared to moderate-intensity continuous training in patients with stable coronary artery disease when total exercise time is held constant.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In patients with stable coronary artery disease, high-intensity interval training leads to larger increases in cardiovascular fitness and lower resting heart rate than moderate-intensity continuous training when both types of exercise take the same amount of time.
See the scientific wording
High-intensity interval training is a time-efficient alternative to moderate-intensity continuous training for improving cardiovascular fitness in patients with stable coronary artery disease, as it achieves greater improvements in VO₂ max and resting heart rate with comparable total exercise time.
Short bursts of intense exercise force the heart to pump more blood with each beat and train the muscles to use oxygen more efficiently, leading to a stronger heart and better lung capacity over time.
What the research says
1 studyFor people with stable heart disease, short bursts of intense exercise improved heart and lung fitness more than longer, steady workouts — even though both took the same amount of time.
