The Claim
High-intensity interval training leads to greater improvements in cardiovascular fitness, as measured by increases in VO₂ max and reductions in resting heart rate, compared to moderate-intensity continuous training in patients with stable coronary artery disease over a 12-week supervised program.
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, 12 weeks of high-intensity interval training results in larger increases in VO₂ max and larger decreases in resting heart rate than 12 weeks of moderate-intensity continuous training.
See the scientific wording
High-intensity interval training improves cardiovascular fitness in patients with stable coronary artery disease more than moderate-intensity continuous training, as measured by greater increases in VO₂ max and greater reductions in resting heart rate over a 12-week supervised program.
Short bursts of intense exercise force the heart to pump more blood with each beat and train it to beat slower at rest, while also growing more tiny blood vessels in muscles to deliver and use oxygen better.
What the research says
1 studyFor people with stable heart disease, doing short bursts of hard exercise with rest in between improved their heart and lung fitness more than doing the same total exercise at a steady, slower pace — and the study proved it with real numbers.
