1. What is FTP?

Functional Threshold Power (FTP) represents the highest average power output you can sustain for approximately one hour. It's a key metric for cyclists to gauge fitness and set training zones.

2. How Does the Calculator Work?

The calculator uses the following formula to estimate FTP from VO2max:

Where:

• \( VO2_{max} \) — Maximum oxygen uptake (mL/kg/min)
• \( weight_{kg} \) — Body weight in kilograms
• 0.3 — Conversion factor accounting for cycling efficiency

Explanation: This formula provides a rough estimate of FTP based on aerobic capacity (VO2max) and body weight, assuming typical cycling efficiency.

3. Importance of FTP Calculation

Details: FTP is crucial for cyclists to determine training intensities, track fitness progress, and pace efforts during races or long rides.

4. Using the Calculator

Tips: Enter your measured VO2max in mL/kg/min and your current weight in kilograms. For best results, use recent test data.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this estimation?
A: This provides a rough estimate. Actual FTP can vary based on cycling efficiency, muscle composition, and other factors.

Q2: What's a good FTP value?
A: FTP varies by individual. Competitive cyclists often have FTP values between 3-6 W/kg, while beginners may be 2-3 W/kg.

Q3: Should I use actual FTP testing instead?
A: For precise training zones, a 20-minute or 60-minute FTP test is recommended. This calculator is for estimation only.

Q4: Does this work for all cyclists?
A: The estimation works best for road cyclists. Track cyclists or those with unusual pedaling efficiency may see different results.

Q5: How often should I update my FTP?
A: FTP can change with training. Serious cyclists test every 4-8 weeks during training seasons.
