Exercise is so important for people with diabetes that The National Institutes of Health NIH recommends minutes of aerobic exercise each week. And the American Diabetes Association recommends that you miss no more than two days of aerobic exercise in a row.
Some people may experience hypoglycemia when they exercise, while others report blood glucose spikes if they work out at certain times of the day or for longer than usual. A meta-analysis published in December in the journal Diabetologia found the risk of developing type 2 diabetes decreases by 26 percent if you engage in moderate-intensity exercise for at least minutes per week. That recommendation aligns with what the U.
The HHS says to exercise at a moderate intensity for at least 2 hours and 30 minutes per week, or at a vigorous intensity for at least 1 hour and 15 minutes per week. According to the ADA, moderate-intensity exercise involves being able to talk but not sing while moving, while vigorous-intensity exercise involves being shorter of breath and not being able to say more than a few words before taking a break.
A small study published in December in the journal Diabetologia particularly suggested walking for 10 minutes after eating may lower blood glucose by 22 percent. That post-meal workout time seems to be key. You may need to check blood sugar levels and have an extra snack to prevent low blood sugar levels. If you're starting a rigorous exercise schedule, like training for a sport, your doctor may recommend that you adjust your insulin dosage to prevent low blood sugar levels.
All teens — not just those with diabetes — need to get a physical before they play a sport. Your doctor will let you know about any changes you should make to your testing schedule or medication while exercising or playing sports. The doctor is likely to give the green light to any activities you want to start — after all, exercise is an important part of diabetes management.
However, doctors may recommend that you steer clear of certain adventure sports like rock climbing, hang gliding, or scuba diving. That's because a person could be seriously hurt if he or she has low blood sugar levels while doing these sports. Your doctor will help you learn what blood sugar levels make it a good or bad time to exercise. He or she will also explain how to take action and get back in the game.
If you notice any of the signs listed below, stop exercising and follow your diabetes management plan. Also, keep an eye on any cuts, scrapes, or blisters, and talk to your doctor if they're really red, swollen, or oozing pus — these could be signs of infection.
By being prepared and knowing how to follow your diabetes management plan, you'll be able to prevent diabetes problems during exercise. After all, professional athletes follow a training and nutrition program to keep them playing their best — just think of your diabetes management plan as your own personal roadmap to exercise success.
