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.

Description
1 study reviewed
In plain English

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.

Why this might work

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.

1 study
  1. Study: Ambulatory heart rate variability in overweight and obese men after high-intensity interval exercise versus moderate-intensity continuous exercise

    In 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.
