Measurement of aerobic and anaerobic endurance: VO₂max, lactate threshold and functional tests
Proper nutrition before testing is essential for obtaining accurate and reliable results. Here are the main recommendations:
Drink 500-600 ml of water 2-3 hours before testing. Avoid caffeine and alcohol for 24 hours before.
Eat a light carbohydrate-containing snack (banana, oatmeal) 3-4 hours before. Avoid heavy, fatty food.
Moderate protein amount (20-30 g) 2-3 hours before. Ensure the body has amino acids for recovery.
Last meal — no later than 2-3 hours before the test. After the test, consume a protein + carbohydrate combination within 30-60 minutes.
Some sports supplements may help achieve better results during testing:
| Supplement | Effect | Recommended Dose | When to Take |
|---|---|---|---|
| Creatine | Increases strength and power | 3-5 g per day | Daily, 30 min before the test |
| Beta-alanine | Reduces muscle acidity | 3-5 g per day | 30-60 min before the test |
| Caffeine | Improves endurance and focus | 3-6 mg/kg body weight | 45-60 min before the test |
| L-citrulline | Improves blood flow, reduces fatigue | 6-8 g | 45-60 min before the test |
| BCAA/EAA | Reduces muscle damage | 5-10 g | Before and after testing |
To achieve better results, it is recommended to follow these principles:
Test every 4-8 weeks so you can track progress and adjust your training program.
Train specifically — if the test measures speed, include sprint exercises; if strength, include progressive overload training.
7-9 hours of quality sleep are essential for optimal athletic form. After intense training, allow 48-72 hours for recovery.
Regularly analyze results — monitor trends, identify weak points and adjust the plan accordingly.
A proper warm-up can improve results. Recommended structure:
Testing must be safe. Key injury prevention rules:
An endurance test assesses how long and at what pace the body can work. The most popular options are running for a set time (for example, the Cooper test) or a set distance for time. Before the test, warm up, choose a measured route and run at an even pace.
Constant conditions are important for the test: the same route, similar time and weather, a rested state. Only in this way will results be correctly comparable between different days.
The result — distance or time — shows aerobic capacity, but evaluate it according to age and sex tables or a specialist's opinion, not in absolute numbers. It is most useful to monitor your own change: if the same test under the same conditions improves every few weeks, endurance is growing.
An additional indicator is heart rate: the same pace with a lower heart rate also shows progress, even if the time has not improved. Such "silent" progress often goes unnoticed if you track only one number.
Do not trust the result if you tested while ill, after insomnia or with great fatigue. The result is also misleading when the route is not measured or the time is recorded approximately.
For a fuller picture, combine with heart rate monitoring (heart rate zones) and VO₂max assessment,. Repeat the test every few weeks, not every training session.
Choose a test that you can perform under constant conditions and that is convenient for you — consistency is more important than the specific choice of method. Record not only the result but also heart rate, weather and how you feel.
Monitor the trend over several months, not fluctuations of individual days. If the result does not change for a long time, review training load and rest — sometimes the problem lies not in training but in a lack of recovery.
If the result improved, do not celebrate too early — check whether the conditions were truly the same. Only improvement observed several times in a row confirms real progress. Also track training volumes so you understand which load gives the most benefit.
Do not compare your result with friends' or numbers seen online — everyone's starting level and training experience are different, so it makes sense to compare only yourself with yourself.
