🥗 Athlete Nutrition Recommendations on Testing Day

Proper nutrition before testing is essential for obtaining accurate and reliable results. Here are the main recommendations:

🚀 How to Improve Testing Results

To achieve better results, it is recommended to follow these principles:

🔥 Warm-Up Protocol Before Testing

A proper warm-up can improve results. Recommended structure:

1. General warm-up (5-10 min): light running, hopping, or cycling — heart rate 120-140 bpm.
2. Dynamic stretching (5 min): leg swings, lunges with rotation, arm circles, hip openers.
3. Specific activation (5 min): exercises that imitate the test at lower intensity (e.g., light jumps before a vertical jump test).
4. Progressive approach (3-5 min): 2-3 repetitions with 60%, 80%, 90% of the estimated maximum load.
5. Rest (2-3 min): full recovery before a maximal attempt.

🏥 Injury Prevention During Testing

Testing must be safe. Key injury prevention rules:

• Medical Screening Before Testing — especially important when there is a risk of cardiovascular disease.
• Proper Technique — incorrect movement technique increases injury risk and distorts results.
• Gradual Load Increase — start at a lower intensity, especially after injuries or a break.
• Proper Equipment and Clothing — wear athletic shoes, use a non-slip surface.
• Qualified Supervisor — testing must be performed or supervised by a specialist.
• Know Your Limits — if pain, dizziness, or other symptoms occur, stop immediately.

How to Use a Lactate Test

A lactate test measures the concentration of lactic acid salt in the blood when load is increased in steps. The athlete runs on a treadmill or pedals a bicycle, and every few minutes a blood sample is taken from the finger or earlobe. The load is increased steadily until the athlete can no longer continue or lactate reaches a predetermined limit.

The most important rule is to perform the test after rest and under the same conditions as previous attempts; otherwise, the numbers will not be comparable. Before the test, it is worth avoiding heavy exertion and following usual nutrition, and repeating measurements at the same time of day. The test must be supervised by a specialist, as blood sampling and load management require experience.

What the Result Shows

While the load is low, blood lactate remains low and almost unchanged. Upon reaching a certain intensity, it begins to rise — first slowly, then sharply. Those two breakpoints are the aerobic and anaerobic thresholds. They determine at what speed or power one can work for a long time without fatigue accumulation, and at what speed or power only for a short time.

This is a much more accurate way to determine training zones than heart rate measurement alone, because lactate directly reflects changes in energy production in the body as load increases.

How to Interpret Thresholds

• Aerobic threshold — the pace at which one can work for hours on end; it is suitable for long training sessions and recovery.
• Anaerobic threshold — the pace one can sustain for approximately half an hour to an hour; it is a benchmark for race pace.
• The gap between them — the zone in which endurance develops; the majority of training volume should take place precisely here.
• Above the anaerobic threshold — short, intense efforts that quickly accumulate fatigue.

It is important to compare not individual numbers but their change over time: if the same lactate level is reached at a higher speed, endurance has improved. More about other tests — fitness tests and BIP test.

Where the Test's Limits Are

A lactate test shows physiological capacity, but not everything. It does not reflect technique, psychological resilience or race tactics. In addition, the result is influenced by sleep, nutrition and even caffeine, so a single inaccurately performed measurement can be misleading. The test also requires equipment and a specialist, so in practice it is performed less often than simpler field tests, for example fitness tests at home.

Finally, thresholds are not constant — they change with training, so one measurement is not enough for the whole season; the result should be updated periodically.

How Often to Test

It is sufficient to repeat a lactate test every few months or before important competitions. Testing too often is expensive and provides no additional benefit, because endurance changes occur slowly. It is more important to train consistently and use the test as a checkpoint that shows whether the chosen direction is correct.
