THREE REASONS TO DO VO2 MAX METABOLIC TESTING
Are you a serious endurance athlete who wants to raise the level of training and competition in the new season? Down below are three reasons why I believe metabolic testing is a key part of this process and how it can help you achieve better results
1. RELIABLE PROGRESS TRACKING AND EASIER TRAINING OPTIMIZATION
Endurance athletes always orient the training process toward one single goal: how to get from the start to the finish line as fast as possible on race day. Measuring progress is therefore simple — a better time equals progress — which is of course true, but based on this alone it is very difficult to optimize the training process.
A faster race time depends on several factors, and the better we understand which of these we have improved through training, the easier it is to repeat or further improve the result. Regular metabolic testing enables exactly that, as it tells us precisely whether:
- VO₂ max has increased,
- one of the ventilatory thresholds has shifted higher or lower,
- we have become more economical.
2. PRECISELY DEFINED TRAINING INTENSITY ZONES
Every endurance athlete measures training intensity in one way or another. Some methods are more effective than others, but most use one or more of the following: a heart rate sensor, speed/pace, a power meter, blood lactate measurement, or simply a perceived exertion scale from 1 to 10.
Some athletes leave the setup of intensity zones to their smartwatch or bike computer, others perform an incremental test with increasing load, or a longer test (e.g. 10, 20, or 30 minutes at maximum pace) and then calculate intensity zones using predefined formulas.
For a rough determination of zones and for athletes with a lower training volume and no major competitive goals, this is perfectly sufficient. However, progress in endurance sports is largely associated with an increased training volume. The higher the training volume, the more important it becomes how training intensity is distributed — and whether it is appropriate for the athlete’s current level of fitness.
Example: Two athletes can achieve the same finishing time in a 10 km race using the same training plan, yet have different intensity zones — one relies more on anaerobic energy systems, the other more on aerobic ones. Without metabolic testing, we cannot know this, but this information can be extremely helpful when deciding how to train most effectively for upcoming competitions.
With metabolic testing, intensity zones are determined precisely based on the individual abilities of each athlete and the physiology of their body, rather than using fixed formulas such as percentages of maximum heart rate, %FTP, and similar.
3. EASIER PLANNING OF NUTRITION BEFORE, DURING AND AFTER TRAINING OR COMPETITION
In recent years, the importance of proper nutrition has grown exponentially in endurance training and competition. The longer the events and the greater the training volume, the more important nutrition becomes.
The higher the movement speed, the more energy is required. The exact amount of energy, of course, depends on several factors, such as the athlete’s body weight, efficiency, aerodynamics, oxygen consumption, and more.
Metabolic measurements provide data on the amount of energy (calories) the body needs to move at a certain speed or to produce a certain amount of power. Based on this, we can more accurately determine how much food should be consumed at a given training or competition intensity — much easier than guessing or experimenting with new nutrition strategies during races and dealing with all the digestive issues that usually come with that process 😉.
CONCLUSION
VO₂ max metabolic testing is not reserved only for professional athletes. It is a tool for anyone who wants to:
- train smarter,
- better understand their body,
- and improve results in the long term.
If you want every training session to truly count, metabolic testing is one of the best first steps you can take. If you have any more questions on training or metabolic testing shoot down below!
