Fitness for Diabetes Prevention

Type 2 diabetes has become an increasingly prevalent health issue in the US, with over 37 million adults or 11.3% of all Americans suffering from the condition. Type 2 diabetes is characterized by high levels of glucose in the blood and is caused by the body’s inability to use insulin effectively. While various factors contribute to the development of type 2 diabetes, including genetics and environment, lifestyle issues such as poor physical fitness and an unhealthy diet are major contributors to its onset. Here, we’ll look at how physical fitness can help in type 2 diabetes control and prevention.

Before diving into the relationship between physical fitness and type 2 diabetes, let’s first understand what physical fitness means. Physical fitness can be defined as the body’s ability to optimally perform physical activities that require aerobic endurance, muscular endurance, flexibility, and strength. Physical fitness is not just about having ideal body composition or being able to run a mile or lift heavy weights; it encompasses a range of physical activities that can improve overall health and well-being.

Fitness and Diabetes: Studies on Prevention

Studies have found that physically active people have a 30 to 50% reduced risk of developing type 2 diabetes. Moreover, people who had higher levels of physical fitness were proportionally less likely to develop type 2 diabetes than those with lower levels of physical fitness. In another study of over 3,600 adults, researchers again found that physical activity was associated with a lower risk of developing type 2 diabetes. Participants who engaged in moderate or vigorous physical activity were less likely to develop type 2 diabetes than those who were sedentary.

How Does Fitness Prevent Diabetes?

So, how does physical fitness for diabetes prevention work? One of the main mechanisms by which physical fitness reduces the risk of developing type 2 diabetes is by improving insulin sensitivity. Insulin sensitivity refers to the body’s ability to use insulin effectively to regulate blood glucose levels. In people with type 2 diabetes, the body becomes resistant to insulin, which leads to elevated blood glucose levels. Physical fitness can help improve insulin sensitivity by increasing the uptake of glucose by skeletal muscle and improving the ability of the liver to regulate glucose metabolism. Together with weight loss, physical activity lowers type 2 diabetes risk by 58% in high risk individuals.

In addition to preventing type 2 diabetes, physical fitness can also help people who have already developed diabetes. Exercise has been shown to improve blood sugar levels, reduce insulin resistance, improve cholesterol, and maintain weight loss in individuals with diabetes. In a study of over 200 individuals with type 2 diabetes, researchers found that a structured exercise program led to significant improvements in A1c levels (a measure of blood glucose control) and body composition.

Cardio vs Lifting Weights: Which is Better for Diabetes?

While physical fitness can be beneficial for diabetes prevention, it’s important to note that not all types of physical activity are created equal. Aerobic exercise, such as jogging, brisk walking, swimming, or cycling, has been shown to be particularly effective in improving insulin sensitivity and glycemic control. Resistance training, such lifting weights or bodyweight exercises, can also be beneficial, but may have a lesser effect on glycemic control. In general, a combination of both aerobic and resistance training is recommended for individuals with type 2 diabetes.

Another important consideration when it comes to physical fitness and type 2 diabetes is the intensity of the exercise. High-intensity interval training (HIIT) has gained popularity in recent years for its effectiveness in improving cardiovascular fitness and reducing insulin resistance. HIIT involves short bursts of high-intensity exercise followed by periods of rest. In a study of individuals with type 2 diabetes, researchers found that a HIIT program led to significant improvements in HbA1c levels and insulin sensitivity compared to a moderate-intensity exercise program.

How to Get Active: Starting Your Fitness Journey to Prevent Diabetes

Are you thinking of starting an exercise program to prevent diabetes but don’t know where to begin? It can be overwhelming to start, but with the right mindset and a little bit of planning, you can be on your way to a healthier and more active lifestyle. Here are five steps to get started on a fitness program:

1. Find an activity you enjoy: One of the most important factors in starting an exercise program is to find an activity that you enjoy. This could be anything from walking, cycling, or swimming, to joining a dance, barre, yoga, or pilates class. If you enjoy the activity, you’ll be more likely to stick to it and make it a regular part of your routine.
2. Start small: It’s important to start small and gradually increase the duration and intensity of your workouts. If you’re new to exercise, aim for 10-15 minutes of physical activity each day, and gradually increase the time and intensity as you get fitter. You don’t need to go to the gym for an hour-long workout every day; even small bursts of activity, known as “exercise snacks” throughout the day can be beneficial. The goal is to get at least 150 minutes per week of moderate-intensity physical activity.
3. Find a partner: Exercising with a partner can be a great way to stay motivated and accountable. Find a friend, family member, or co-worker who has similar fitness goals and schedule regular workouts together. You can also join a fitness class or group, which can provide a supportive environment and help you stay on track.
4. Pick a goal: Setting a goal can help you stay motivated and focused. Whether it’s running a 5k, losing weight, or improving your fitness level, having a specific goal in mind can help you stay committed to your fitness program. Write down your goal and keep it somewhere visible, like on your fridge or bathroom mirror, to remind you of what you’re working towards. But remember to focus on progress and the journey, as even reaching part way to your goal is a success in itself!
5. Schedule it in: Just like any other important appointment or meeting, schedule your exercise time in your calendar. Make it a priority and don’t let other things get in the way. It’s also important to be flexible and adaptable – if you miss a workout, don’t beat yourself up, just get back on track as soon as possible.

Starting an exercise program can be challenging, but it’s also incredibly rewarding. Remember to be patient, consistent, and kind to yourself. By finding a fitness activity you enjoy, starting small, finding a partner, picking a goal, and scheduling it in, you can create a sustainable exercise routine that will help you achieve your health and fitness goals.

Cautions and Challenges

Despite the numerous benefits of physical fitness to prevent diabetes, it can be challenging for individuals with type 2 diabetes to engage in physical activity. Diabetes-related complications such as neuropathy, retinopathy, and cardiovascular disease can limit the type and intensity of exercise that is safe for these individuals. Additionally, fluctuations in blood glucose levels during exercise can be dangerous if not managed properly.

To ensure safe and effective physical activity, it’s helpful for people with type 2 diabetes to work with their healthcare provider and a certified exercise professional to develop an individualized exercise plan. This plan should consider the individual’s current fitness level, any existing medical conditions, and their goals for physical activity. Regular monitoring of blood glucose levels before, during, and after exercise may also be necessary to ensure safety and effectiveness, especially for people on insulin or sulfonylureas like glipizide or glyburide.

Diet and Nutrition

In addition to physical activity, diet is another important factor in the prevention and management of type 2 diabetes. A diet rich in whole grains, fruits, vegetables, lean protein, and healthy fats can help improve insulin sensitivity and glycemic control. On the other hand, a diet high in ultra-processed foods and refined carbohydrates, saturated and trans fats, and added sugars, especially in sugar sweetened beverages, can contribute to the development and progression of type 2 diabetes.

Takeaways

Physical fitness plays an important role in the prevention and management of type 2 diabetes. Regular physical activity, particularly aerobic exercise, can improve insulin sensitivity and glycemic control, reduce the risk of developing type 2 diabetes, and improve overall health and well-being. However, it’s important for individuals with type 2 diabetes to work with their healthcare provider and a certified exercise professional to develop a safe and effective exercise plan. A healthy diet is also important in the prevention and management of type 2 diabetes. By making lifestyle changes that include regular physical activity and a healthy diet, individuals with type 2 diabetes can improve their quality of life and reduce the risk of diabetes-related complications.
