Freediving and the Effects of Oxygen Consumption

July 30, 2022 4 min read

How does freediving influence oxygen consumption? In a previous article, I discussed the effects of oxygen consumption on breath-hold times and the VO2max. Now, I'll talk about the effects of oxygen consumption on the body and the way that this relates to breathing. Read on to discover how to increase the amount of oxygen in your body while freediving. Then, I'll explain the science behind the benefits of freediving.

Longer Breath-Hold Times

One of the goals of freedivers is to increase their breath-hold time. The key to improving your time is understanding the limits of oxygen rationing. Your internal organs consume oxygen as you move, so a higher heart rate limits the duration of breath-holds. You can improve breath-hold times by addressing your weaknesses. To achieve longer breath-hold times, work on improving your cardio fitness.

The most effective way to increase your time in a static apnea is to practice equalization techniques. Equalization is a key element of pre-equalization and helps you save precious oxygen. Practicing the Vasalva Method is a great way to equalize your lungs before diving. The Vasalva Method is one of the most effective equalization methods underwater. While a short, shallow breath is not ideal for equalizing, a short, deep breath can result in a much longer time in the water.

Lower Oxygen Levels

The ability to cope with low oxygen levels during a freediving exercise could improve the safety of cardiac surgery. Freedivers have conditioned their brain and heart to function without adequate oxygen. If they could help cardiac surgeons perform their operations with less risk of hypoxic blackout, the process could be repeated to protect their heart and brain. But the question remains, can a freediver actually rescue a victim trapped in a car underwater?

Despite this danger, freediving has increased in popularity in recent years. However, most diving is conducted in water depths up to 20 metres, where the physiologic effects of progressive hypoxia are more severe. The dramatic changes in pressure imposed on the body during a freediving dive can affect the diver's heart rate and blood volume and have several physiological effects. Direct compression of air-filled cavities can reduce the partial pressure of oxygen, which can result in hypoxic BO.

Increased Tolerance to CO2

In addition to the increased blood volume, endurance athletes also have a higher red blood cell concentration and increased CO2 storage capacity. These traits can help the athlete's body to tolerate higher levels of CO2, which is essential for freediving. Although the increased red blood cell count and volume of freedivers may benefit endurance athletes, the occasional diver will not benefit from these attributes. Increased CO2 tolerance is the goal of endurance athletes.

To improve one's personal tolerance to CO2, one should start using oxygen tables. These tables can help the freediver increase his or her tolerance to CO2. These tables can be used to gradually increase the time spent underwater in each breath hold. A diver can start using oxygen tables after increasing his or her tolerance to CO2. The oxygen table will work on a different physiological response from the freediver, thus helping the freediver increase the amount of time they can hold a breath, while reducing the length of the recovery phase.


VO2max is a standard measure of aerobic fitness. It measures the amount of oxygen your body can process in one minute. While you may be able to reach a certain amount of VO2max at a certain level, you may not always be able to maintain this level. This is where VO2max comes in handy. By measuring your VO2max, you can see if you have what it takes to keep up with the demands of your workout.

VO2max measures how well your body can utilize oxygen during exercise. Your heart rate declines due to the loss of oxygen in your blood. For most people, the old formula for the maximum heart rate holds true. But the brain requires so much oxygen that even a small decrease in oxygen can result in mental fatigue. Taking supplemental oxygen can increase your concentration, memory, and reaction time.


To prepare your body for the intense physical demands of freediving, you can make your own diet that includes plenty of proteins, carbohydrates, and fats. Protein is essential for your body as it is necessary for energy production and maintenance, as well as for muscle growth and preservation. When choosing the type of protein you eat, make sure you spread the amount of protein you eat out over the day. Ideally, you should eat at least one serving of protein after each workout.

Depending on the type of freediving you're doing, different types of food may be more or less effective for you. For example, if you've recently eaten, you may not need to consume any electrolyte-rich food, but if you dive without eating, you'll need to take electrolyte supplements. Some of these pills contain sugar, which helps increase water absorption.
