What is your VO2 Max?

VO2 max is a valuable indicator of cardiovascular health because it reflects the efficiency of the cardiovascular system in delivering oxygen to working muscles during exercise. The cardiovascular system includes the heart, blood vessels, and blood, and its primary function is to transport oxygen and nutrients to tissues while removing waste products.

Here’s how VO2 max is linked to cardiovascular health:

Heart Efficiency: VO2 max is influenced by the efficiency of the heart in pumping blood. During exercise, the heart pumps oxygenated blood to the muscles at an increased rate. A higher VO2 max suggests that the heart is capable of pumping a larger volume of blood per minute, ensuring an adequate supply of oxygen to meet the demands of physical activity.
Stroke Volume: VO2 max is closely related to stroke volume, which is the amount of blood ejected from the left ventricle of the heart with each beat. A well-conditioned cardiovascular system, as indicated by a higher VO2 max, often corresponds to an increased stroke volume. This means that the heart can pump more blood with each contraction, leading to better oxygen delivery to the muscles.
Capillary Density: An efficient cardiovascular system is also associated with an optimal capillary network in muscles. Capillaries are tiny blood vessels that facilitate the exchange of oxygen and nutrients with muscle tissues. Regular aerobic exercise, which contributes to a higher VO2 max, promotes the development of a dense capillary network, enhancing oxygen delivery to working muscles.
Blood Volume and Oxygen-Carrying Capacity: Physical training, especially aerobic exercise, can increase blood volume and the oxygen-carrying capacity of the blood. This is beneficial for overall cardiovascular health and contributes to the ability to transport more oxygen to tissues, as reflected in a higher VO2 max.
Mitochondrial Density: The cardiovascular system works in conjunction with the respiratory and muscular systems to support aerobic metabolism. A higher VO2 max is associated with an increased number and efficiency of mitochondria in muscle cells. Mitochondria are the energy-producing organelles in cells, and their presence and function are vital for sustained aerobic activity.

In summary, VO2 max is a comprehensive measure that reflects the integrated functioning of the cardiovascular system during exercise. A higher VO2 max suggests better cardiovascular efficiency, which is associated with a reduced risk of cardiovascular diseases, improved aerobic endurance, and overall better cardiovascular health.

Why should you know what your VO2 Max is for Longevity Health?

VO2 max, or maximal oxygen consumption, is a measure of the maximum amount of oxygen that an individual can utilize during intense exercise. It is often used as an indicator of cardiovascular fitness and aerobic endurance. The term “VO2 max” reflects the maximum volume of oxygen (VO2) that a person can consume per minute during exercise.

VO2 max is considered a valuable marker for longevity and overall health for several reasons:

Cardiovascular Health: VO2 max is closely linked to cardiovascular health. A higher VO2 max indicates a more efficient cardiovascular system, including the heart and blood vessels. This efficiency is associated with a reduced risk of cardiovascular diseases, which are major contributors to mortality.
Aerobic Endurance: Individuals with a higher VO2 max generally have better aerobic endurance. This means they can sustain physical activity for longer durations without experiencing fatigue. Improved endurance is associated with a healthier and more active lifestyle, which can contribute to longevity.
Metabolic Efficiency: Higher VO2 max values are often associated with better metabolic efficiency. This means that the body is more effective at using oxygen to produce energy, particularly in the presence of oxygen (aerobic metabolism). Efficient energy production is linked to overall metabolic health.

Testing VO2 max typically involves a graded exercise test conducted under controlled conditions, usually in a laboratory or clinical setting.

Here’s a brief overview of how VO2 max testing is done:

Baseline Measurements: Before the test, baseline measurements such as height, weight, and resting heart rate are taken. The individual may also be asked about their medical history and current fitness level.
Exercise Protocol: The individual then performs a graded exercise test on a treadmill or stationary bike. The intensity of exercise is gradually increased at specific intervals, while the person’s oxygen consumption, heart rate, and other parameters are monitored.
Gas Analysis: During the test, the participant wears a mask connected to a gas analyzer. This equipment measures the amount of oxygen consumed and carbon dioxide produced, providing data for the calculation of VO2 max.
Endpoint: The test continues until the participant reaches their maximum exertion or is unable to maintain the required intensity. The point at which oxygen consumption plateaus despite increasing exercise intensity is considered the VO2 max.

While VO2 max is a valuable indicator, it’s important to note that longevity is a complex outcome influenced by various factors, including genetics, lifestyle, and overall health. Regular physical activity, a balanced diet, and other healthy lifestyle choices play crucial roles in promoting longevity.

Testing VO2 max typically involves a graded exercise test conducted in a controlled setting, often in a laboratory or clinical environment. Professional athletes, fitness enthusiasts, and individuals undergoing cardiac rehabilitation may undergo VO2 max testing.

Here’s a general overview of the process:

Preparation: Before the test, baseline measurements such as height, weight, and resting heart rate are taken. The individual may also be asked about their medical history and current fitness level.
Exercise Protocol: The individual then engages in a graded exercise test on a treadmill, stationary bike, or other exercise equipment. The test involves gradually increasing the intensity of exercise at specific intervals.
Gas Analysis: During the test, the individual wears a mask connected to a gas analyzer. This equipment measures the amount of oxygen consumed and carbon dioxide produced, providing data for the calculation of VO2 max.
Monitoring: Throughout the test, various parameters such as heart rate, blood pressure, and respiratory rate are monitored. The test continues until the participant reaches their maximum exertion or is unable to maintain the required intensity.
Calculation: The point at which oxygen consumption plateaus despite increasing exercise intensity is considered the VO2 max. It’s expressed as the maximum volume of oxygen consumed per minute (in milliliters or liters per minute) relative to body weight (in kilograms).

How do you improve your VO2 Max as you age??

As for improving VO2 max as you age, it’s important to note that VO2 max tends to decline with age, primarily due to factors such as a decrease in muscle mass, changes in heart function, and a reduction in the body’s ability to transport and utilize oxygen.

However, regular aerobic exercise has been shown to mitigate this decline and even improve VO2 max.

Here are some strategies to enhance and maintain VO2 max as you age:

Aerobic Exercise: Engage in regular aerobic exercise, such as brisk walking, running, cycling, swimming, or other activities that elevate your heart rate and breathing. Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, or 75 minutes of vigorous-intensity exercise.
Interval Training: Incorporate interval training into your routine. Alternating between short bursts of high-intensity exercise and periods of lower intensity or rest can be an effective way to improve cardiovascular fitness.
Strength Training: Include strength training exercises to maintain and build muscle mass. Strength training can improve overall functional fitness and contribute to better performance during aerobic activities.
Consistency: Stay consistent with your exercise routine. Regular, ongoing physical activity is essential for maintaining and improving cardiovascular fitness.
Cross-Training: Mix up your workouts by incorporating a variety of aerobic activities. This can prevent boredom and provide a more comprehensive cardiovascular workout.
Consultation with a Professional: Before starting a new exercise program, especially if you have pre-existing health conditions, it’s advisable to consult with a healthcare provider or fitness professional to ensure that your chosen activities are safe and appropriate for your individual needs.

As of my last knowledge update in January 2022, the available research suggested that both steady-state aerobic training (commonly associated with Zone 2) and high-intensity interval training (HIIT), including sprint interval training (commonly associated with Zone 5), can be effective for improving VO2 max and promoting metabolic health.

The Movement Economy Marker

PNOE: The Movement Economy (or Mechanical efficiency as it can also be found in literature), shows the relationship between the work you produce in relation to the calories you consume or the efficiency ratio with which your body is transforming energy from nutrients into work, in other words how efficiently you reserve energy during exercise(all training zones).

Imagine two individuals with identical calorie-burning capacities, each tasked with an exercise routine. The first individual expends the entire set amount of calories (x) right at the outset of the test.

In contrast, the second person efficiently distributes and utilizes the same x amount of energy seamlessly throughout the entire training session. The second person exhibits a superior movement economy, demonstrating a more effective and sustainable approach to energy expenditure.

A higher score means our body is more economical to complete a task using a minimum amount of calories (as a result of training and predominantly endurance based training), whilst a low score indicates we have to use more energy to complete the specific task compared to what we would normally expect from someone with the same demographics.

Movement economy can be either good or bad depending on the perspective you are looking at it for.

Lets hypothesize that we have the exact same demographics, me and you, and I have 10% in Movement Economy and you have 100%. If we were both to run 5 miles I would burn more calories than you would.

From a weight loss perspective you would like to be as close as it gets to 10% which would prove that your body is “uneconomical” meaning that you are burning more calories in comparison to your demographics.

From a performance / endurance perspective you would like to be as close as it gets to 100% to be very economical. This is a metric that all of my marathon runners are paying extra attention to.

Mechanical Efficiency?

The concept of the Movement Economy, also referred to as Mechanical Efficiency in some literature, is a measure that examines the relationship between the work performed by your body and the calories you consume. It essentially quantifies the efficiency with which your body transforms the energy derived from nutrients into physical work. In simpler terms, it evaluates how efficiently your body uses energy during exercise across various training zones.

The Movement Economy considers the efficiency ratio, which is the relationship between the work output (the physical activity or exercise you engage in) and the calories expended in the process.

A higher movement economy suggests that your body is effectively converting the energy from consumed calories into productive work, indicating a more efficient use of energy during exercise.

This concept is crucial in understanding how efficiently your body utilizes energy during different training intensities or zones. By assessing movement economy, one can gain insights into how well the body preserves and utilizes energy, which can be valuable for optimizing training strategies and overall performance.

Measuring Movement Economy or Mechanical Efficiency involves assessing the relationship between the work performed and the calories expended during physical activity.

There are different methods and metrics used to quantify this relationship, depending on the specific context and goals of the assessment. Here are a few common approaches:

Metabolic Efficiency Testing:

Direct measurement of oxygen consumption (VO2) and carbon dioxide production (VCO2) during exercise can provide insights into the efficiency of energy utilization. Respiratory exchange ratio (RER) is calculated based on the ratio of VCO2 to VO2. A lower RER may indicate more efficient energy utilization.

Caloric Expenditure Monitoring: Track and measure the calories burned during a specific exercise or physical activity. This can be done using wearable fitness trackers, heart rate monitors, or specialized equipment in a laboratory setting. Compare the work output (e.g., distance covered, speed, resistance levels) to the calories expended during the activity.

Efficiency Ratios: Calculate efficiency ratios by dividing the work output by the calories consumed or expended. This ratio provides a numerical representation of how efficiently energy is being converted into work during exercise. For example, if you’re running, the efficiency ratio might be calculated as distance covered per calorie burned.

Biomechanical Analysis: Analyzing the biomechanics of movement can provide insights into the efficiency of muscle contractions and joint movements. Techniques such as motion capture, force plate analysis, or electromyography (EMG) may be employed to study the mechanics of specific movements.

It’s important to note that the measurement of Movement Economy can vary depending on the specific goals and parameters of the study or assessment. Laboratory-based assessments, such as metabolic testing, provide detailed and accurate data but may not be practical for everyday use. On the other hand, wearable devices and practical efficiency ratios offer more accessible options for individuals and athletes to monitor and optimize their movement economy in real-world settings.
