We know that physical activity helps to transfer blood glucose into the cells, but you may be surprised what a difference it can make.

The following research investigated that more in detail (Burns AM, et al., 2021).


The participants were 10 healthy 24-year-old men. Forearm glucose uptake was determined during a 180-minute oral glucose challenge before and after 24, 48 and 72 hours of immobilization of one forearm, and before and after 72 hours of the contralateral non-immobilized arm.

After 24 hours of immobilization the glucose uptake was reduced by 38% and even more by 48 hours. After 72 hours it was 63% less than the non-immobilized arm.

Muscle contraction is very important for glucose uptake.
