The Claim

Low-volume high-intensity interval training is safe and well tolerated in adults with stable coronary artery disease during supervised cardiac rehabilitation, with only one serious adverse event (new-onset atrial fibrillation) possibly related to exercise among 187 participants over 8 weeks.

Source: High-intensity interval training in cardiac rehabilitation (HIIT or MISS UK): A multi-centre randomised controlled trial.

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.

Description
1 study reviewed
In plain English

In adults with stable coronary artery disease undergoing supervised cardiac rehabilitation, low-volume high-intensity interval training resulted in only one serious adverse event (new-onset atrial fibrillation) among 187 participants over 8 weeks, with no other significant safety concerns.

Why this might work

Short bursts of intense exercise force muscles to use more oxygen, which triggers the creation of more energy-producing structures inside muscle cells. This allows the muscles to work harder without needing as much blood flow from the heart, reducing stress on the heart during exercise and preventing dangerous strain.

1 study
  1. Study: High-intensity interval training in cardiac rehabilitation (HIIT or MISS UK): A multi-centre randomised controlled trial.

    For people with stable heart disease doing supervised rehab, short bursts of intense exercise were just as safe as slower, steady exercise — only one person had a possible heart rhythm issue out of 187 people.
