My fasting blood sugar is 120. After 30 minutes of playing hockey, it rises to 250. I am 52 years old. Should I continue playing hockey or not? Which exercise should I do to reduce my blood sugar level?
Only 39% of people with diabetes exercise. Congratulations on being part of the minority. Being active for 150 minutes a week is commonly recommended by healthcare professionals. Moderate exercise like walking and bicycling for two and a half hours a week is doable. Assuming you do not have any medical restrictions.
Research does show that high-intensity sports can raise your blood sugar. This will occur if the sport you are participating in exceeds your heart rate capacity. Commonly referred to as the VO2 max; your peak or maximum oxygen consumed while playing hockey could put you in the 80% or greater zone. Difficulty breathing, unable to speak while exercising might be signs that you are at your VO2 max level.
Exercising at the VO2 max stresses your body. The glucose released from your liver in response to the stress hormones can be higher than what you require; giving you a higher blood sugar.
Depending on whether you have type 1 or type 2 diabetes, exercise will impact your blood sugars differently.
Type 1 Diabetes
People with type 1 diabetes that exercise needs to be concerned with hypoglycemia, low blood sugar during and after exercise. The length of time and type of exercise requires consideration before starting a workout.
Your healthcare professional can assist you in adjusting your medication to prevent a hypoglycemic episode.
Type 2 Diabetes
People living with type 2 diabetes are either insulin resistant or their body does not produce enough insulin.
Exercise utilizes blood sugar for energy. Hypoglycemia may be an issue if you are on a type 2 medication or injecting insulin. So definitely check in with your healthcare team on exercise guidelines.
Should You Stop Playing Hockey?
I would speak to your healthcare professional about the different types of exercises and the intensity required to keep your blood sugars closer to normal. Having your medical record on hand, your healthcare professional can guide you and assist you in refining the level at which you like to exercise.
