Hey! I just joined. I noticed your post is a month and a half ago, so you may not end up seeing this, but I'll proceed with a brief post just incase. I am a physiotherapist, exercise enthusiast, and have had diabetes for 26 years. Exercise and diabetes is my specialty
you will notice variances in your blood sugar response depending in the intensity of your exercise. Mild exercise will usually slowly drop your sugars with minimal effects in the 24 hours after (ex. Golfing), moderate exercise (ex. Pilates or snowshoeing) may drop the sugars more intensely and likely would require a greater insulin decrease up to two hours before, during, and potentially for hours later. Intense bursts such as racing/running intervals or intense video exercise like "insanity" can rapidly increase your blood sugars due to the stress hormone response. They can spike within a few minutes of a sprint, so ideally you should check your sugars every ten minutes or so the first few times you perform an activity to determine how your body responds. Some people require additional insulin to accommodate for the interval training, but then you need to remover the sugars may be more prone over the 24 hours following intense exercise and then a decrease in insulin would be required! Don't let it overwhelm you
just prick your finger lots with any new exercise, and it will become second nature what to do once you see your patterns! Good luck!!!
