The Claim
In patients with stable coronary artery disease, 12 weeks of high-intensity interval training reduces resting heart rate by an average of 4.4 bpm compared to a 2.9 bpm reduction with moderate-intensity continuous training, indicating a greater reduction in resting heart rate with high-intensity interval training.
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.
Among patients with stable coronary artery disease, 12 weeks of high-intensity interval training lowers resting heart rate by 4.4 beats per minute more than moderate-intensity continuous training.
See the scientific wording
In patients with stable coronary artery disease, 12 weeks of high-intensity interval training reduces resting heart rate by an average of 4.4 bpm (from 72.5 to 68.1 bpm), which is significantly greater than the 2.9 bpm reduction observed with moderate-intensity continuous training (from 73.2 to 70.3 bpm), suggesting enhanced cardiac efficiency with HIIT.
The heart beats slower at rest because the nervous system sends stronger signals to slow it down and weaker signals to speed it up, making the heart work less hard without losing its ability to pump blood.
What the research says
1 studyFor people with stable heart disease, doing short bursts of intense exercise for 12 weeks lowered their resting heart rate more than doing steady, moderate exercise — meaning their hearts didn’t have to work as hard when they were at rest.
