Always wanted a smaller waist? Scientists have discovered that the answer could be something as simple as taking frequent small breaks from sitting.
A U.S. National Health and Nutrition Examination Survey published in the European Society of Cardiology’s European Heart Journal revealed that participants who took more small breaks from sitting had smaller waistlines than those who did not. This was true even for those who were spent up to 21.2 hours a day sedentary. For the 25% of participants who took the most breaks from sitting, the survey found that waistlines were on average 1.61 inches or 4.1 centimeters smaller than the 25% of participants who took the fewest breaks. The survey, led by University of Queensland researcher followed 4,757 people, all aged 20 and older. The survey lasted for seven days, during which participants wore an accelerometer on their right hips when they were awake. These accelerometers measured the intensity of the participants’ physical activity. Low levels of intensity were equated with sedentary periods.
Having a small waistline indicates less abdominal fat, which in turn is an indicator for better heart health. Larger waists, on the other hand, are linked to cardiovascular disease and high blood pressure as well as higher risk for type 2 diabetes. Another study published in the journal, Obesity, links increases in waistlines to increased chance of premature death.
Participants who took more frequent breaks from sitting also had lower levels of C-reactive protein (CRP). CRPs are produced by the liver. Production is correlated with the level of inflammation in the body. The study also found that taking breaks had a significant effect on lowering HDL-cholesterol, particularly in non-Hispanic whites. Conversely, those who were had higher sedentary times tended to have larger waists, higher HDL-cholesterol, CRPs, triglycerides and insulin.
The benefits of frequent breaks from sitting is linked to muscle activity in the legs and back. When sitting or reclining, these large muscles are largely inactive. However when standing, these muscles are forced to continually contract in order to maintain posture. This increased activity helps to clear plasma triglycerides, which is a risk factor for cardiovascular disease.
Still not convinced? By taking frequent breaks and doing some stretches while sitting at work will also save you from frequent neck and back pain.
