The Claim

In young overweight and obese men, moderate-intensity continuous exercise (MICE) produces no significant change in 24-hour ambulatory heart rate variability when compared to high-intensity interval exercise (HIIE) or a non-exercise control condition.

Description
1 study reviewed
In plain English

In young men who are overweight or obese, moderate continuous exercise does not change heart rate variability over 24 hours compared to high-intensity interval exercise or no exercise.

See the scientific wording

In young overweight and obese men, moderate-intensity continuous exercise (MICE) does not significantly alter 24-hour ambulatory heart rate variability compared to either high-intensity interval exercise (HIIE) or a non-exercise control condition, indicating that MICE does not produce a measurable autonomic effect on HRV in this population under the conditions tested.

Why this might work

After moderate exercise, the body increases activity in both the system that speeds up the heart and the system that slows it down, so the overall effect on heart rhythm stays the same.

What the research says

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 session of moderate exercise didn’t change their heart’s nervous system activity during the day or night, just like doing nothing or doing intense exercise. So, moderate exercise didn’t have a noticeable effect on heart rhythm recovery.
