A recent scientific study has shown that the duration of exercise plays a more important role than its type or intensity in helping to control blood sugar levels.
The study included 58 adults who had been newly diagnosed with type 2 diabetes. Researchers tracked their physical activity for 26 weeks using fitness trackers and analyzed changes in glucose levels and glycated hemoglobin (HbA1c) (the main indicator of long-term blood sugar control) in the participants.
The results showed that the length of exercise was the factor most strongly associated with improved health indicators in the patient, while the intensity or type of exercise (whether strength training or aerobic exercise) did not show any significant effect on its own. The role of the long duration of exercise was particularly prominent during the first weeks of the exercise program followed by the participants.
The researchers estimated that increasing the average duration of exercise from 30 to 45 minutes was associated with a decrease in glycated hemoglobin (A1C) levels of approximately 0.3%. Although this effect seems small, with regular exercise, it can significantly improve overall health.
The scientists pointed out that their findings could help simplify recommendations for patients: instead of complex exercise programs, it is enough to focus on increasing the duration of exercise. They believe that acquiring the habit of exercising for longer and more comfortable periods may be one of the most effective strategies for controlling blood sugar levels.
