[Physical exercise and type 2 diabetes: Is 3 x 10 minutes a day better than 30 minutes?--secondary publication]

We compared the effects on glycaemic control of two different exercise protocols in elderly men with type 2-diabetes; one 30-minute session per day (1 x 30) and three 10-minute sessions per day (3 x 10). Cardiopulmonary fitness increased in both groups. Improvement in glycaemic control was only found in the 3 x 10 group. A likely explanation is that the total energy expenditure during training performed as multiple sessions is higher than the expenditure achieved during a single session per day.
