The phrase ‘Exercise is Medicine‘ is very applicable when it comes to preventing or managing diabetes, especially Type 2 Diabetes (T2DM). Exercise is a fantastic tool to assist with lowering blood glucose (sugar) levels and improving overall metabolic health. This short blog will cover why exercise works so well for T2DM and what the recommended type of exercise is?
How does exercise help with Type 2 Diabetes?
There are two primary mechanisms where exercise plays a vital role in blood glucose control. Firstly, exercise improves insulin sensitivity – where the body becomes more responsive to insulin – therefore promoting increased removal of glucose from the blood vessels.
Secondly, exercise helps to remove glucose from the blood, independent to the effect of insulin. Think of your muscles as a sponge for glucose, every muscle contraction the muscle cells soak up and utilise glucose from your blood. This effect is elevated 24-36hrs post exercise, meaning the benefits last long after you’ve finished your exercise session!
If you are consistent with your exercise, this will prolong your ability to maintain blood glucose levels within an optimal target range.
What’s the best exercise to do?
Both cardiovascular and resistance training have shown significant benefits to improving blood glucose control. However, a combined approach consistently shows the most beneficial reductions in long-term blood glucose levels.
Most adults with diabetes should aim to engage in 150 minutes or more, of moderate-to-vigorous intensity activity weekly. This can be spread over at least 3 days per week, aiming to have no more than 2 consecutive days without activity.
For cardiovascular exercise (walking, running, cycling, swimming, etc), higher intensities are recommended to elicit the largest benefit. Typically, this is prescribed in an interval format – with a period of higher intensity exercise, followed by a period of lighter intensity.
For resistance training, it is recommended to target large muscle groups, aiming for 2-3 sets and 8-10 repetitions for each exercise. This is the optimal target range, however everyone will have a different starting point and rate of progression.
Final Takeaways
- A combination of resistance and cardiovascular exercise is best
- Higher intensities of exercise typically lead to improved results
- No more than 2 consecutive days without activity
- EXERCISE IS MEDICINE!!
