Exercise like playing a sport can have significant impacts on blood glucose levels and the sensitivity of insulin.

There are two main types of exercise, both of which have varying effects on blood glucose levels. Aerobic exercise (e.g. running, cycling) causes an increase in insulin sensitivity and a decrease in blood glucose concentration as more glucose is used by the body’s cells to meet the body’s energy demands. This impact can be quite noticeable and it is therefore recommended to always adjust your insulin requirements before, during and after exercise as well as bringing along a high GI snack such as a banana or orange juice. There is a risk of hypoglycemia when participating in aerobic exercise.

Anaerobic exercise in the form of resistance training (e.g. weight lifting) can have the opposite effect and cause blood glucose levels to rise due to the secretion of counter-regulatory hormones.
