The Claim
In young overweight and obese men, 24-hour ambulatory heart rate variability is equivalent following high-intensity interval exercise and moderate-intensity continuous exercise.
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 young men who are overweight or obese, heart rate variability measured over a full day is the same after high-intensity interval exercise and after moderate-intensity continuous exercise.
See the scientific wording
In young overweight and obese men, 24-hour ambulatory heart rate variability does not differ between high-intensity interval exercise and moderate-intensity continuous exercise, suggesting that both exercise modalities have similar effects on autonomic modulation over a full day.
After either type of exercise, the heart's automatic control returns to normal by balancing the signals that speed up and slow down the heart, so the heart rate variability stays the same all day and night.
What the research says
1 studyIn young men who are overweight or obese, one workout of intense bursts of exercise and one workout of steady, moderate exercise had the same effect on their heart's automatic control throughout the whole day and night. The study found no meaningful difference between the two types of exercise.
