Ftp Calculator

The FTP Calculator allows users to determine their Functional Threshold Power, power-to-weight ratio, and classify their power output into specific training zones based on a selected test protocol and input average power and weight.

How to Use the FTP (Functional Threshold Power) Calculator

The FTP Calculator is a tool designed to estimate your Functional Threshold Power (FTP) based on performance tests. Follow these steps to use the calculator effectively:

Step 1: Choose Your Test Protocol

Begin by selecting the type of test protocol you followed from the list available in the calculator.

  • 20-Minute Test: Choose this option if you have completed a 20-minute test.
  • 8-Minute Test: Select this option for an 8-minute test.
  • 5-Minute Test: Use this if your test duration was 5 minutes.

Make sure you select the option that correctly corresponds to your test. This choice will determine the calculation logic used for estimating your FTP.

Step 2: Enter Your Average Power

Input the average power you recorded during your test in watts. Enter a value between 50 and 2000 watts.

Note: Ensure the power is accurate as this directly influences the result of the FTP calculation.

Step 3: Enter Your Weight

Provide your weight in kilograms. This should be a value between 30 and 200 kg.

The calculator uses this input to determine your power-to-weight ratio, adding another layer of insight to your cycling performance assessment.

Step 4: Review Your Results

Once all required fields are filled, the calculator will display your results:

  • FTP (Functional Threshold Power): This value represents the maximum power you can sustain for an hour, calculated based on your selected test duration and average power.
  • Power-to-Weight Ratio: Calculated by dividing your FTP by your weight, providing insight into your performance relative to your body weight.
  • FTP Zones: The calculator will display several training zones (Zone 1 to Zone 5), each represented as a power range based on percentages of your FTP. These zones help guide your training intensity levels from recovery (Zone 1) to VO2 Max (Zone 5).

Use these results to guide your training and monitor your performance improvements over time.

Conclusion

By following these simple steps, the FTP Calculator will give you a comprehensive understanding of your cycling performance, tailored to your specific testing protocol and personal metrics.
