People with type 2 diabetes who sit all day have a riskier blood fat mixture than those who move around or exercise periodically throughout the day, according to researchers in Australia.
“We have previously shown that interrupting prolonged sitting with light intensity activity after meals reduces risk factors for heart disease and diabetes, such as elevated blood sugars and high blood pressure,” said lead author Dr. Megan S. Grace from Baker Heart and Diabetes Institute and Monash University in Melbourne.
Past research has also shown that patients with type 2 diabetes have an altered blood fat profile that contributes to inflammation and insulin resistance and that exercise can improve this profile.
“What we found interesting about this study was that breaking up sitting also reduces levels of lipids (fats) in the bloodstream that are associated with risk for type 2 diabetes and its complications,” Grace said by email. “Our study showed that breaks which include either simple resistance exercise or light walking were generally equally beneficial in reducing blood lipids.”
Researchers looked at blood lipid profiles in 21 overweight or obese adults with type 2 diabetes under three different conditions: sitting throughout the day (rising only to use the bathroom); breaking up sitting by light walking for three minutes every 30 minutes; and breaking up sitting by doing light exercise like squats and knee raises for three minutes every 30 minutes.
