Exercise-induced changes in blood sugar levels -

Put more simply, your body works through exercise using supply and demand. During high-intensity exercises, it doesn't have the supply of energy on hand to fuel your workout.

So, it releases glucose, immediately meeting the energy demand to fuel your workout while causing a short-term spike in blood sugar.

During low-intensity exercise, your body has enough energy on hand to meet the demand, so blood glucose typically stays steady or decreases. There are no two ways about it. Even with the odd glucose spike, exercise is beneficial to your blood sugar levels in the long term.

According to the American College of Sports Medicine and the American Diabetes Association , all exercise forms improve insulin sensitivity and blood sugar control.

But why does exercise have such a positive impact on your blood sugar levels? When you have just eaten or are resting, glucose uptake into your muscles relies on insulin.

If your blood sugar level rises like after eating a meal loaded with carbs , it stimulates insulin release. The insulin then acts on your cells to use or store the excess glucose. The uptake of glucose is much different when you are exercising.

According to the American Journal of Physiology , exercise increases muscle glucose uptake up to fold compared to being at rest! And, this uptake does not rely on insulin. Scientists suggest that it is due to a protein called glucose transporter type 4 known as GLUT4.

But even they are still figuring out exactly how it happens. In this case, it acts as an effective lifestyle treatment for anyone with these conditions. And, as mentioned at the beginning, exercise can reverse insulin resistance and prediabetes. Pretty great, right? Most human cells contain tiny organelles called mitochondria.

These tiny powerhouses convert chemical energy into energy that the body can use by turning glucose into oxygen and ATP. Research published in the journal Cell Metabolism shows that exercise increases the number of mitochondria in the muscle cells. Not only that, but it causes them to function better too!

The more efficiently they work, the better you perform. More mitochondria mean your cells turn more glucose into energy. This makes your body more insulin sensitive. So, through exercising, you are helping to lower your risk of diabetes. Obesity is a known risk factor for developing diabetes and heart disease.

And, if you carry that extra fat around your abdomen, you are at a much higher risk of all-cause mortality than people who store their excess fat in their thighs. Exercise reduces fat cell size, specifically abdominal fat cells. Why is this important? It is the ability to use fat, rather than carbohydrates, as fuel.

Now, there is a lot of debate about the intensity level and exercise duration required to achieve optimal fat oxidation. But, what scientists have proved is that the best way to increase the fat burning process is to exercise regularly. Fat burning depends on several things, including the number and quality of mitochondria.

Yes, we are back to those little powerhouses. And, as we already know, exercise increases both the amount and quality of mitochondria, resulting in improved fat oxidation.

The more fat you burn, the more you improve your insulin sensitivity, lower your blood sugar levels, and reduce your risk of diabetes. When you deplete your glycogen stores through exercise, you increase your available storage space for future incoming glucose.

This increased availability is something that you can take advantage of. You can replenish your glycogen stores by eating carbohydrates while minimizing your glucose responses and fat gain.

You may have had a sports coach or trainer tell you to eat carbohydrates immediately after exercise.

This is a great technique for athletes, but also a great trick for us to have more flexibility in our diets. Choose the correct type of training to deplete your glycogen stores such as resistance training to take full advantage of the increased storage space and improve your metabolic flexibility.

One of the biggest roadblocks preventing metabolic flexibility for most is being physically inactive. Having good metabolic flexibility means your body can easily switch between breaking down carbs or fat for fuel.

Different types of workouts assist in your body becoming more metabolically flexible. Mitochondria play a vital role in determining metabolic flexibility, and exercise helps increase the number of mitochondria you have.

Exercise also promotes anabolic flexibility better ability to store or use glucose , which again, leads to improved metabolic flexibility. Regardless of the type of exercise, staying physically active can help improve metabolic flexibility and protect against the development of metabolic disease.

The relationship between exercise and blood sugar is a positive one. That is clear to see. But, this relationship does change depending on the type of exercise you do and if you have diabetes.

Strength training includes exercises like weightlifting free or machine , bodyweight exercises, and resistance bands to build muscle strength, mass, and endurance.

Strength training is anaerobic. When you work out anaerobically, your body uses glucose as your primary energy source. It breaks down glucose without using oxygen. This provides you with high bursts of energy over short periods. The American Diabetes Association advises that anaerobic exercise improves blood sugar control and insulin sensitivity.

Research published in the International Journal of Cardiology suggests that strength training can provide more effective blood sugar regulation than cardio in people with type 2 diabetes. Additionally, engaging in strength training helps to build our lean muscle mass.

Glycogen, that glucose storage space we touched on earlier, can be stored in only the liver or the skeletal muscle. So the more muscle mass you have, the more potential storage capacity you have for incoming glucose.

This equals out to lower and more controlled blood glucose values. Keep in mind, though, that intense strength training is one of the activities that can cause your blood sugar levels to rise post-exercise. Remember that this rise is not a negative thing, and glucose values will usually go down again about an hour later.

In the end, the benefit of the anaerobic exercise far outweighs the glucose spike. Zone 2 is aerobic exercise. Aerobic exercise is cardiovascular training that increases your heart rate and breathing for sustained periods. Zone 2 training is a type of heart rate training.

It uses your maximal heart rate MHR as a guide for the intensity of the activity. There are five zones in total, ranging from very light to very hard intensity.

When training in zone 2, your body optimizes using both fat and glucose for fuel. It achieves the highest amount of fat-burning for energy and improves the function of mitochondria.

You get the maximum effect of this type of cardio training by doing it regularly. The effect is cumulative, and over the long term, it significantly helps blood sugar control. High-intensity interval training HIIT combines both aerobic and anaerobic forms of exercise.

It alternates more extended periods of cardio with short bursts of high-intensity activities. In other words, HIIT gives you the best of both worlds! Thanks to the wide variety of exercises available under the HIIT workout umbrella, you can easily tailor this method to suit your lifestyle while reaping the benefits of glucose control and shedding abdominal fat.

Never discount the positive effect a stroll in the park can have on your health. Walking causes your heart to beat a little faster and your breathing rate to increase.

This is going to promote your muscles to use more glucose and helps regulate your blood sugar levels. In fact, a study published in Diabetes Care shows that three short minute walks a day are as effective at lowering blood sugar levels as one long minute walk at the same pace.

The same study states that completing a short walk after your evening meal has the most significant effect on regulating your blood sugar levels. Remember, exercise does not have to be vigorous to be impactful.

Walking is an effective physical activity to help control your blood sugar levels. So, even a brisk walk after dinner can make a big difference to your metabolic health.

Eat too many carbs before exercising, and your sweat session may not be enough to keep your blood glucose within your goal range.

Now that you know what causes a blood glucose rise after or during exercise, you may expect and accept it during your next workout session because you know the benefits of exercise outweigh the rise in glucose.

Physical activity is important for everyone with diabetes. Managing glucose levels with any form of exercise is possible once you understand your personal patterns doing regular blood glucose checks and keeping a workout log can help and making adjustments that make sense to you and your lifestyle.

: Exercise-induced changes in blood sugar levels

Why Does Exercise Sometimes Raise Blood Glucose?

Prolonged or severe hypoglycemia can be life threatening. It may lead to the following:. Exercise places additional energy demands on the body, so the body needs to respond by burning more glucose. Hypoglycemia can occur in people who already have low glucose levels, or those whose bodies metabolize glucose quickly.

Certain factors can contribute to EIH, including :. In some people, exercise triggers a considerable spike in insulin, which removes glucose from the blood. This spike can cause sudden hypoglycemia, even when a person is well nourished and does not take medications to lower their blood glucose.

If a person experiences chronic EIH, a doctor may recommend medication to reverse the condition. However, making appropriate lifestyle changes can address the problem for most people.

EIH is not necessarily a sign of diabetes. Exercise alone can substantially lower blood glucose. However, people with diabetes have additional risk factors for hypoglycemia. Untreated diabetes causes hyperglycemia , which is high blood glucose.

Individuals who take medications to manage their diabetes are at increased risk of hypoglycemia if they take more than they need. Not eating enough food to match activity levels can also be a cause. Also, people with diabetes may become hypoglycemic if they take medication for diabetes when fasting or starting a restrictive diet.

Mild EIH does not usually require treatment. In many cases, the condition occurs because a person did not eat enough food before working out. To avoid EIH, individuals should try eating a carbohydrate-rich meal 1—2 hours before a workout.

Chronic EIH can sometimes signal an underlying issue with insulin production. If a person experiences chronic EIH, a doctor may prescribe diazoxide to treat low blood sugar. In rare cases, a doctor may recommend removing a part of the pancreas to slow insulin production.

Below are some strategies for preventing EIH in individuals with diabetes and those without the condition. The American Diabetes Association ADA recommends that people who take diabetes medications to control their blood glucose check their blood glucose levels before exercising.

According to the ADA, a person should recheck their blood glucose after 15 minutes. A review notes that anaerobic exercise, such as high intensity interval training HIIT , may reduce the risk of hypoglycemia in people with diabetes. HIIT involves brief bursts of intense activity, followed by a rest and then another brief burst of intense activity.

Individuals who feel shaky or dizzy during a workout should stop and take a break. They should try drinking 4 oz g of juice or eating a piece of toast, then resuming their workout later.

Hypoglycemia can be life threatening if blood glucose levels drop too low. A person who experiences one or more of the following symptoms requires emergency medical attention:. People should consult a doctor if they frequently experience EIH or hypoglycemia at other times.

If the person has diabetes, this could be a sign that their diabetes medication dosage is incorrect or that they are taking too much insulin.

EIH is hypoglycemia that occurs during or following exercise. The condition can affect people with and without diabetes.

Individuals with diabetes are at increased risk of developing EIH, especially if they take insulin or other medications to manage their blood glucose. In such cases, a person should speak with a doctor about the possibility of adjusting their medication dosages.

In people without diabetes, EIH is usually due to not eating enough before exercising, or not giving the body sufficient time to adapt to a new exercise routine.

If a person continues to experience frequent EIH despite taking appropriate preventive measures, they should seek guidance from a doctor to determine the underlying cause. Hypoglycemia is low blood sugar that can cause headaches, weakness, and anxiety.

And more recently, in , experts released an international position statement on glucose management for exercise using continuous glucose monitoring CGM in type 1 diabetes. And overall, the information can be overwhelming and hard to follow.

Colberg , PhD, professor emerita of exercise science at Old Dominion University in Norfolk, Virginia, and creator of Diabetesmotion. So, when someone does intense but short activities, BG often rises due to releasing too many hormones. Ginger Vieira, advocate, author of several instructional diabetes books , and current digital content manager at Beyond Type 1, called on her experience as a former health coach and competitive powerlifter and Ashtanga yoga instructor to describe the effect of some of the most common mechanisms for glucose spikes during intense exercise: lactic acid, adrenaline, and fasted exercise.

Lactic acid. This can easily spike your blood sugar over points. Fasted exercise. Exercising on an empty stomach can lead to a glucose spike, especially right after waking up.

Clearly, many mechanisms can cause a spike in glucose levels during exercise. No wonder, it can be so difficult to know what to do to bring glucose levels back down. Christel Oerum, certified personal trainer and founder of Diabetes Strong and Diabetic Foodie , offered an alternative way to look at this question.

So, when you do certain types of workouts, predominantly anaerobic exercises , your body tries to ensure that you have the energy to be successful.

It does this by releasing hormones that allow energy, in the form of glucose, to be released into your bloodstream. And that can raise blood sugars. This response is not unique to people with diabetes. Oerum suggests combining anaerobic with aerobic exercises.

This approach will balance the effects and typically make BG levels come down soon after the exercise session is done. Of course, if your exercise objective is to bring your BG levels down immediately, then aerobic exercise like walking, swimming, or skipping rope is going to be the effective choice.

Ultimately, it is the presence of insulin that determines when and how quickly BG levels come down. So, try to assess the situation in terms of your insulin intake, or insulin on board IOB.

BG spikes caused by bursts of adrenaline can be hard to anticipate, as they happen most often smack in the middle of a an exercise session. This means that rather than treat the spike immediately, you most likely will need to wait and take additional insulin after the fact. More insulin is also needed when the spike results from fasted exercise.

Some additional insulin will be needed, but not so much that it leads to a hypoglycemic episode during or after exercise. Unfortunately, there are no hard and fast rules for making these insulin dosing adjustments.

Each situation for each person will require an individualized response. That being said, both Vieira and Oerum suggest taking notes and tracking your experience so that you can learn from your experiences. You may find that for you personally, particular activities have a predictable BG spike effect.

Over time you can develop a routine that allows you to both get the exercise you need and anticipate those frustrating spikes. Once you understand why BG levels spike during exercise, and accept that this is not necessarily a bad thing, you will hopefully notice a mental shift, away from being frustrated and disappointed toward appreciating what you can do in response.

While there is no one-size-fits-all guidance, know that over time you can build an exercise routine that includes small amounts of glucose and insulin dosing that keeps your BG levels manageable.
