The Claim
The acute reduction in heart rate resulting from leg-fidgeting during prolonged sitting in young women is of similar magnitude to the acute reduction in heart rate resulting from standing breaks, despite differences in movement frequency and duration between the two interventions.
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 women sitting for long periods, moving the legs frequently in small motions reduces heart rate by about the same amount as standing up for short breaks, even though leg-fidgeting takes much less total time.
See the scientific wording
The acute heart rate reduction from leg-fidgeting during prolonged sitting in young women is comparable in magnitude to that from standing breaks, despite leg-fidgeting requiring only 1 minute of movement every 4 minutes versus 5 minutes of standing every 20 minutes.
Moving the legs gently while sitting squeezes veins in the lower body, pushing more blood back to the heart. This fills the heart more fully, so each beat pumps out more blood. Because the heart can move enough blood with fewer beats, it slows down.
What the research says
1 studyThis study found that wiggling your legs for 1 minute every 4 minutes lowers your heart rate just as much as standing up for 5 minutes every 20 minutes — so leg-fidgeting works almost as well but takes way less time.
