The FTP (Functional Threshold Power) Calculator is an essential tool for cyclists and triathletes aiming to measure their current fitness level and enhance their training plans. By entering power data from a specific test, the calculator estimates the maximum power output (FTP) a rider can sustain for an hour. This value is crucial for determining specific training zones, optimizing workouts, and improving overall performance.

• Personalized Training: The calculator offers customized training zones based on your current power output, allowing for more targeted and effective training sessions.
• Performance Benchmarking: FTP serves as a reliable metric for gauging improvements in cycling fitness over time.
• Race Strategy Planning: Understanding your FTP can help plan pacing strategies for race day, ensuring you perform at your best without burning out prematurely.
• Motivation and Goal Setting: Setting measurable goals based on FTP can be highly motivating for athletes focused on improving their race times.

To calculate FTP, cyclists can choose between two popular tests:

1. 20-minute Test: The rider maintains the highest possible average power over 20 minutes. FTP is then estimated as 95% of this average power.
2. Ramp Test: The rider performs increasingly harder intervals until exhaustion. FTP is estimated as 75% of the final 1-minute power.

Using the FTP value, different training zones can be defined, each serving a specific purpose in your training regimen:

• Zone 1 (Active Recovery): Less than 55% of FTP. Used for recovery rides.
• Zone 2 (Endurance): 56-75% of FTP. Builds aerobic endurance.
• Zone 3 (Tempo): 76-90% of FTP. Improves sustainable power.
• Zone 4 (Lactate Threshold): 91-105% of FTP. Increases the ability to sustain high power output.
• Zone 5 (VO2 Max): 106-120% of FTP. Enhances aerobic capacity.
• Zone 6 (Anaerobic Capacity): 121-150% of FTP. Improves high-intensity efforts.
• Zone 7 (Neuromuscular Power): More than 150% of FTP. Boosts sprinting power.

FTP Concept: Functional Threshold Power (FTP) is analogous to the lactate threshold in running or swimming. It represents the highest power output a cyclist can sustain for an hour without a rapid build-up of lactate in the muscles, which would lead to fatigue. FTP is a critical metric for endurance athletes, as it determines the intensity of training zones.

Scientific Foundations: The methodology behind the FTP calculator is grounded in exercise physiology and endurance training principles. FTP closely correlates with the anaerobic threshold, a key determinant of endurance performance. The concept is well-supported by scientific literature and practical coaching approaches.

How to Use the FTP Calculator

• Calculate FTP: Use the FTP calculator by entering your power data from a 20-minute or ramp test.
• Set Training Zones: Use the calculated FTP to define your training zones.
• Plan Your Training: Structure your workouts based on these zones for more effective training.

Warm-up:

10 minutes easy spinning: Gradually increase your cadence and effort.

3 x 1-minute efforts: Ride at a high intensity (~100-110% of your estimated FTP) with 1-minute recovery between efforts.

5 minutes easy spinning: Recover and prepare mentally for the test.

The Test:

Start steadily: Begin the 20-minute test at a pace you believe you can sustain for the entire duration.

Maintain a consistent effort: Focus on maintaining a steady power output. Avoid starting too hard and fading.

Monitor your metrics: Keep an eye on your power and heart rate, but don't let them dictate your effort entirely. Go by feel as well.

Finish strong: In the final few minutes, if you have the energy, try to increase your effort slightly.

Cool-down:

10 minutes easy spinning: Gradually reduce your effort and allow your body to recover.

Warm-up:

10 minutes easy spinning: Gradually increase your cadence and effort.

3 x 1-minute efforts: Ride at a high intensity (~100-110% of your estimated FTP) with 1-minute recovery between efforts.

5 minutes easy spinning: Recover and prepare mentally for the test.

The Test:

Start at a low intensity: Begin at a manageable power level (~50% of your estimated FTP).

Incrementally increase power: Increase the power output in small, regular increments (e.g., 20-30 watts every minute).

Continue until failure: Ride until you reach a point where you cannot maintain the power output for the full minute.

Monitor your metrics: Focus on maintaining smooth pedaling and breathing. Keep an eye on your power and heart rate.

Cool-down:

10 minutes easy spinning: Gradually reduce your effort and allow your body to recover.
