Only recently has the topic of exercise and mitochondria or mitochondrial function gained widespread popularity. However, scientific research has long established that regular exercise has a positive effect on mitochondrial health. But what exactly are mitochondria, and why are they important for your overall health and fitness?
In this article, we’ll explore the essential role mitochondria play in energy production, how strength training boosts their function, and how incorporating a weighted vest into your workouts can amplify these benefits even further.
What are Mitochondria?
The human body is made up of trillions of cells. In each cell, except those that don’t need energy, like the red blood cell, there are tiny powerhouses called mitochondria. They’re like the batteries of your cells, providing the energy your body needs to function.
Different cells contain varying densities of mitochondria depending on their energy demands. Some of the cells with the most mitochondria are those in your muscles, liver, and kidneys because they need large amounts of energy to work properly.
Inside each mitochondrion, nutrients from the food you eat—carbohydrates, fats, and proteins—are broken down and converted into the primary energy currency of your cells, adenosine triphosphate (ATP). This ATP is the fuel that powers your body, enabling it to perform basic functions and support high-performance workouts or endurance activities.
Why is Mitochondrial Health Important?
Mitochondrial health refers to the condition and function of your mitochondria. It's important because these tiny powerhouses play a crucial role in your body's energy production, metabolism, and overall health. Optimizing mitochondrial function is essential because it will improve:
- Energy Production - More efficient mitochondria mean sustained energy levels, less fatigue, and improved endurance.
- Athletic Performance - Stronger mitochondria help the body recover faster, improving muscle efficiency and strength.
- Metabolism - A well-functioning mitochondrial system burns fat and glucose more efficiently, aiding in weight management.
-
Longevity - Mitochondrial dysfunction is linked to aging and chronic diseases, such as diabetes, Alzheimer’s, and cardiovascular conditions.
By understanding and improving your mitochondrial health, you can potentially extend your lifespan and enjoy a healthier, more active life. With improvements to mitochondrial efficiency and increasing your body’s creation of new mitochondria, you can increase your energy levels, boost your metabolic rate, and even slow the aging process. Strength training is one of the most effective ways to achieve this.
How Strength Training Improves Mitochondrial Function
When you engage in strength training exercises, such as lifting weights, using resistance machines, or doing bodyweight exercises, you create small tears in your muscle fibers. In response, your body repairs and strengthens them, making your muscles larger and more powerful. This process also has a profound effect on the mitochondria within your cells. Here’s how strength training enhances mitochondrial function:
1. Increased Creation of New Mitochondria
It makes sense that the more muscle you build and the power you need, the more mitochondria your cells will make to provide for the increase in your energy demand. This increased mitochondria results in a more efficient breakdown of energy from food, energy production, and storage. In other words, it can result in better metabolism, more energy, and improved endurance.
2. Enhanced Mitochondrial Efficiency
The quality of the mitochondria is just as important as the quantity. Strength training improves mitochondrial respiration, meaning your mitochondria become more efficient at converting oxygen and nutrients into usable energy. This leads to increased stamina, improved muscle recovery, and better overall metabolic function.
3. Reduced Oxidative Stress
The process of energy production produces waste materials called free radicals. Too many free radicals in the cells can lead to oxidative stress, which is like the rusting of your cells. It damages cells and accelerates aging. Strength training boosts the production and action of antioxidant enzymes, chemicals that neutralize free radicals. This has a protective effect on the function of mitochondria, preventing muscle fatigue and improving exercise performance.
4. Improved Insulin Sensitivity
Sensitivity to insulin, a hormone that regulates blood sugar levels, is a marker of a healthy metabolism. The opposite is insulin resistance, a major factor in metabolic diseases such as diabetes. Strength training enhances insulin sensitivity by improving the absorption and breakdown (i.e., metabolism) of sugar. This healthy sugar metabolism, in turn, results in healthy and resilient mitochondria because they are the site of this metabolic process.
5. Prolonged Mitochondrial Health
The natural aging process causes mitochondrial function to decline, leading to decreased energy production, slow metabolism, and muscle loss, not to mention an increased risk of chronic diseases. Strength training can slow down mitochondrial aging by boosting the creation of new mitochondria. By promoting cellular repair and regeneration, strength training helps maintain mitochondrial number and efficiency, prolonging mitochondrial health.
Added Benefits of Strength Training with Weighted Vests
You can further enhance mitochondrial function by incorporating a weighted vest into your workouts. With a high-quality weighted vest like Aion’s, you can:
Increase the Resistance of Bodyweight Exercises.
The added weight adds the extra challenge to your squats, lunges, and push-ups. This increased resistance makes your muscles work harder, stimulating your cells to boost mitochondria production and function.
Optimize HIIT Workouts.
High-intensity interval training is one of the best exercises to burn calories in a short time, improve endurance, and boost post-workout metabolism. Using a weighted vest during HIIT forces your body to generate even more energy, increasing the demand for more mitochondria.
Improve Cardiovascular Efficiency.
Strength training with a weighted vest increases oxygen consumption. This forces your lungs to work harder to take in oxygen and your heart to distribute oxygen all over your body. As a result, the mitochondria also work hard to convert this oxygen into energy, enhancing both endurance and recovery.
Human biologist, biohacker, and longevity expert Gary Brecka said it best in his Ultimate Human podcast episode, “Better Than Cardio? How Weighted Vests Hack Your Fitness Biology”. And the Aion vest is his favorite:
“This isn’t just your average weighted vest. It’s a game-changer. Aion’s design goes way beyond just adding weight; it disappears on your body. Combining compression, fractional weight, and heat-capturing technology to help you work harder even without thinking about it. And unlike traditional vests that put strain on your back and shoulders, Aion activates your core and boosts your blood flow.” - Gary Brecka
Increase Fat-burning and Metabolic Efficiency.
The extra resistance from a weighted vest increases the energy demand of your strength training session. This demand translates to better metabolic function and improved mitochondrial performance, helping your body become more efficient at using fat and sugar for fuel. In a recent study using the Aion weighted vest, participants burned significantly more calories during both low- and high-intensity workouts.
During a walking test, caloric expenditure increased by 18%—burning 548 calories with the Aion vest compared to 463 without. In a HIIT test, the results were even more striking, with a 69% increase in calories burned—371 with the Aion vest versus 219 without. These results highlight how wearing the Aion vest can help you get more out of every movement, maximizing fat-burning potential with no extra time added.
Strengthen Bones and Joints.
Bone and joint cells also depend on a large number of mitochondria to be healthy. The added load from a weighted vest can stimulate the growth of bones and joints and increase their density. Strength training with a weighted vest supports stronger bones and joints for better movement. This allows you to train harder and longer without injury and can prevent bone density issues like osteoporosis.
Maximizing Mitochondrial-Boosting Workouts
To get the most mitochondrial benefits out of your weighted vest, incorporate the following into your routine:
- Strength training - 2 to 4 times a week, wear a weighted vest and perform bodyweight exercises or lift free weights. This promotes muscle growth and mitochondrial creation.
- HIIT workouts - 1 to 3 times a week. Short bursts of intense effort and periods of recovery maximize mitochondrial efficiency.
- Cardio exercises - Walking, hiking, or sprints. Cardio with a weighted vest increases endurance and mitochondrial density.
- Proper recovery and nutrition - Fuel your body with nutrient-dense foods and allow proper rest between each exercise session. This ensures your body has enough time and resources to repair, regenerate, and grow stronger mitochondria.
