1. What is VO2 Max?

VO2 max represents the maximum amount of oxygen your body can utilize during intense exercise. It's a key indicator of cardiovascular fitness and aerobic endurance, particularly important for cyclists.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( Power_{20min} \) — Average power output over 20 minutes (watts)
• \( Weight \) — Body weight in kilograms
• 12 — Conversion factor to estimate VO2 max

Explanation: This formula estimates VO2 max based on your power-to-weight ratio during a 20-minute maximal effort.

3. Importance of VO2 Max

Details: VO2 max is crucial for endurance athletes as it determines aerobic capacity. Higher values indicate greater cardiovascular fitness and endurance potential.

4. Using the Calculator

Tips: For accurate results, perform a 20-minute maximal effort time trial on your bike, record your average power output, and enter it along with your current weight.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this estimation?
A: This provides a reasonable estimate but may vary ±5-10% from lab-tested VO2 max values.

Q2: What are typical VO2 max values for cyclists?
A: Recreational cyclists: 35-50, trained: 50-65, elite: 65-90 mL/kg/min.

Q3: How can I improve my VO2 max?
A: Through high-intensity interval training, endurance rides, and strength training.

Q4: Does this work for all cyclists?
A: Best for road cyclists. Accuracy may vary for track cyclists or those using different bike types.

Q5: How often should I test my VO2 max?
A: Every 6-8 weeks to track fitness progress during training cycles.
