VO2Max Is a Measure of Body Fitness, Here's How to Calculate It!

Feeling not easily tired during exercise doesn't necessarily mean your physical fitness is optimal. VO2Max is one measure that can describe the body's ability to use oxygen during high-intensity physical activity.

This number often appears in fitness test results or smartwatches, especially for those who regularly do cardio workouts. The problem is, not everyone knows what that number means, how to get it, and whether its value is considered good.

So, don't immediately get fixated on the VO2Max number on your device. Let's understand how to measure, read, and improve VO2Max so you don't misinterpret the results.

What is VO2Max in Physical Fitness?

VO2Max is the maximum amount of oxygen the body can use during intense physical activity. Its value is generally expressed in mL/kg/minute, which is the amount of oxygen the body uses per minute based on body weight.

VO2Max is often used to describe cardiorespiratory fitness. This ability involves the lungs, heart, blood vessels, blood, and muscles in taking, transporting, and using oxygen.

The higher the VO2Max, generally the better the body's ability to sustain physical activity that requires the work of the cardiorespiratory system. Even so, VO2Max is not the only indicator of health and needs to be viewed along with other factors.

Why is VO2Max Important for Physical Fitness?

VO2Max is important because it provides an overview of the body's ability to supply and use oxygen during physical activity. Therefore, this number is widely used in fitness evaluation, sports, and research on cardiorespiratory health.

The American Heart Association refers to cardiorespiratory fitness as an important indicator of physiological condition related to various health outcomes. Higher levels of cardiorespiratory fitness are also associated with a lower risk of cardiovascular disease and mortality.

For people who regularly exercise, VO2Max can also be used to track fitness progression over time. However, it is better to observe trends in change with consistent measurement methods than to compare a single number from different devices or tests.

Factors Affecting VO2Max

VO2Max is not only influenced by fitness level but also several other factors that affect the body's ability to use oxygen. Some of the main factors include:

1. Age: VO2Max tends to decrease with age.
2. Gender: Average male and female VO2Max can differ due to differences in body composition and physiological factors.
3. Fitness level: People who regularly do aerobic exercise generally have a higher VO2Max.
4. Genetics: Genetic factors also influence aerobic capacity and the body's response to exercise.
5. Body composition: Body weight and body mass can affect the VO2Max value calculated relative to body weight.
6. Type of exercise: Intensity, duration, frequency, and consistency of exercise can affect VO2Max development.
7. Environmental conditions: Temperature, humidity, and altitude can affect performance and VO2Max measurement results.

Overall, VO2Max is influenced by a combination of body factors, exercise habits, and environmental conditions. Understanding these factors helps you assess and improve cardiorespiratory fitness more accurately.

How to Calculate VO2Max

1. Direct Measurement with CPET

A comprehensive method for measuring VO2Max is cardiopulmonary exercise testing (CPET) using a treadmill or bicycle. Exercise load is gradually increased while analyzing breathing and gas exchange.

This test measures oxygen used and carbon dioxide exhaled during activity. Because it is done directly, the results are more accurate than estimation methods.

2. Estimation Using a Treadmill or Bicycle

VO2Max can be estimated through an exercise test using a treadmill or bicycle. Data such as speed, incline, duration, or workload are used to estimate oxygen consumption.

This method is more practical than CPET, but the results are still an estimation. Therefore, the value may differ from direct measurements through gas analysis.

3. Field Tests and Smartwatches

Field tests and smartwatches can estimate VO2Max based on data such as activity, speed, and heart rate. This method is more practical as it does not require laboratory examination.

However, smartwatch numbers should be used as an indication of fitness progression. To monitor changes, use consistent devices and measurement conditions.

What is an Ideal VO2Max Number?

There is no single VO2Max number that can be called ideal for everyone. Its value is influenced by age, gender, fitness level, body condition, type of activity, and measurement method.

As an illustration, FRIEND data from cardiopulmonary exercise testing shows that the average VO2Max value decreases with age.

In men, the recorded average was around 47.6 mL/kg/minute at 20–29 years old and around 25.8 mL/kg/minute at 70–79 years old. In women, the numbers were around 37.6 mL/kg/minute and 18.3 mL/kg/minute in the same age group.

24.2

These numbers are not absolute standards or fitness diagnoses, but rather references from specific study populations. In fact, FRIEND research shows differences based on age, gender, and test modality, so interpretation must use appropriate references.

How to Effectively Increase VO2Max

1. Regular Cardio Exercise

Cardio exercise such as running, cycling, or swimming is the main foundation for increasing VO2Max because it trains the heart and lungs to work more efficiently. If done regularly, the body will be more optimal in absorbing and using oxygen during activity.

The ideal frequency for beginners is 3–5 times a week with a duration of 30–60 minutes per session for noticeable results. Make sure the intensity is adjusted to your ability, add exercise variations, and do warm-ups and cool-downs to avoid injury.

2. Interval Training or HIIT

HIIT or high-intensity interval training has proven effective in increasing VO2Max in a shorter time compared to regular exercise. The pattern involves a combination of intense activities such as sprints with recovery periods, so the body is trained to work more efficiently in oxygen use.

A simple example is a 30-second sprint followed by a 1-minute leisurely walk repeated several times according to ability. Start at a low intensity, increase gradually, and allow sufficient rest so that the body does not experience overtraining.

3. Long-Distance Running Training

Long-distance running training helps increase endurance by training the cardiovascular system to work for long durations. The body will get used to using oxygen stably, so stamina increases significantly.

The strategy is to gradually increase distance or duration while maintaining efficient running technique and breathing patterns. This exercise is suitable not only for runners but also for anyone who wants to improve their daily fitness and endurance.

4. Consistent Exercise and Healthy Lifestyle

VO2Max improvement will not be maximized without consistent exercise supported by a healthy lifestyle. Factors such as sufficient sleep, balanced nutrition, and stress management greatly affect body performance.

If exercise is done irregularly or the lifestyle is poor, VO2Max progress will be slow. Therefore, a combination of planned exercise, adequate recovery, and healthy habits is the key to optimal results.

Start Improving VO2Max with Consistent Exercise

VO2Max is an important indicator of cardiorespiratory fitness because it shows the body's ability to use oxygen during intense activity. However, this number needs to be interpreted based on age, individual characteristics, and measurement method.

Rather than just chasing a certain number, focus on building consistent aerobic exercise habits and gradually increasing intensity. That way, you can monitor fitness progress more realistically without getting fixated on a single number.

To make exercise more comfortable and regular, you can also complement your routine with fitness equipment that suits your needs. Discover the best running gear collection from SVRG to support your cardio and fitness training.
