The Importance of a VO2 Max Test for Competitive Cyclists

When it comes to striving for optimal fitness and speed, numerical data cannot be disputed. Specifically, let’s examine the VO2 max assessment.

The three main metrics utilized in cyclist training plans are power, cadence, and heart rate. However, while these metrics are significant in the overall picture, they only make up a small part of it. Each of these metrics has its own significance in the pursuit of fitness and performance, but the most insightful evaluation often comes from a test that is not commonly taken by most cyclists.

VO2 max testing is considered the top method for evaluating an endurance athlete’s aerobic abilities and determining how to effectively improve those abilities through personalized training. The information gathered from a VO2 max test eliminates the need for guesswork in future training, as it provides precise insights on which areas to focus on in order to achieve optimal fitness levels.

Understanding VO2 Max

To begin with, it is crucial to comprehend the definition of VO2 max. In essence, VO2 max denotes the maximum capacity of oxygen that the body can utilize, and it serves as an indicator of an individual’s athletic ability and potential. This is why it is common to see the names of renowned cyclists linked with their VO2 max measurements, such as Greg Lemond’s impressive result of 95 during his peak performance and Miguel Indurain’s score of 90 in between his Tour de France victories.

The different aspects of breathing, such as inhaling, exhaling, and utilizing the breath, are all important factors in determining fitness. However, they only demonstrate true fitness when they work together harmoniously with the cardiovascular system. Simply having a large intake of breath is not enough to indicate fitness if you cannot effectively use the majority of the air you inhale. Similarly, having a high uptake of oxygen is not beneficial if you are not able to intake a significant amount in the first place.

The discussion about oxygen and its role in cycling performance is closely related. Oxygen is the fuel that powers your body’s engine, and it enters through the lungs and is then carried to the muscles by the cardiovascular system. Red blood cells play a crucial role in this process as they absorb oxygen and transport it to where it is needed, while also carrying carbon dioxide back to the lungs for exhalation. This crucial process is evaluated for effectiveness during the VO2 max test.

The Procedure for the VO2 Max Test

Before the examination, your weight and height will be measured, and a laboratory technician will record your age, weight, and height. These measurements will be used to analyze your VO2 max results and provide an indication of where you fall on the average spectrum for your specific range.

In the laboratory, assistants will provide you with a mask that may remind you of the one worn by the notorious comic book antagonist, Bane. Despite its appearance, this mask is essential for the test as it measures your intake and vital capacity, determining how much oxygen your lungs can hold. Additionally, a heart rate monitor is used in conjunction with the mask.

The assessment begins with the participant preparing and attaching the necessary medical devices, followed by mounting a trainer and starting to pedal at a low intensity level. This initial phase serves as a warm-up and usually begins below 100 watts. Once sufficiently warmed up, the trainer, also known as a cycling ergometer, will gradually increase the wattage every few minutes until the participant reaches the point of exhaustion caused by entering the anaerobic zone (when the body experiences oxygen debt). After reaching exhaustion, the participant will continue to pedal at a lower intensity for fifteen to twenty minutes while waiting for the test data to be collected.

Insights from VO2 Max Testing

It is worth noting that achieving a high score on a VO2 max test does not guarantee that you will perform well in races or on the road. To better understand this, imagine if you scored 80 on the test, which is equivalent to professional cyclists on the world tour, yet you struggle to keep up with the group on the third lap of a local Tuesday night ride. What could be the reason behind this?

Despite possessing a very high VO2 max, your capacity to sustain high-intensity efforts is limited to a short duration. The extent of your ability to maintain a high-intensity level is determined by your FTP (functional threshold power). A low FTP means you can only sustain approximately 50-60% of your maximum VO2. For instance, if your VO2 max is 80 but your FTP can only support half of that, you will inevitably be left behind by someone with a lower VO2 max of 58 but who can maintain 90% of it on a climb.

Utilizing the VO2 Max Findings

The example provided highlights the effectiveness of VO2 max testing when used in conjunction with previous performance records, power data, and timing. Utilizing these factors can assist in determining a targeted training approach. If your test results are high but not reflective of your actual performance, focusing on improving your functional threshold power would be a clear and beneficial training direction, leading to improved overall fitness and ability.

VO2 max testing provides an all-inclusive, objective evaluation of your physical fitness at the time of the test. With a comprehensive set of data to support your perceived exertion, a coach can design a customized training program that specifically targets your weaknesses and improves them. Additionally, dietary suggestions can be formulated based on the results of the test, which is vital because the easiest way to enhance your VO2 max is by shedding pounds (without compromising power).

In the current era of abundant information, data serves as the benchmark for athletes to accurately identify training goals and reach their full potential. For competitive cyclists, VO2 max testing is crucial and should be given proper consideration for those aiming to elevate their cycling performance.
