1. What is Heart Rate Zone Calculation?

Heart rate zone calculation helps cyclists determine optimal training intensities based on their Functional Threshold Power Heart Rate (FTP HR). Different percentages of FTP HR correspond to different training zones for various workout goals.

2. How Does the Calculator Work?

The calculator uses the heart rate zone formula:

Where:

• \( FTP_{HR} \) — Functional Threshold Power Heart Rate (bpm)
• \( \% \) — Percentage of FTP HR (0-1)

Explanation: The equation calculates the target heart rate zone by multiplying your FTP HR by the desired percentage intensity.

3. Importance of Heart Rate Zones

Details: Training in specific heart rate zones helps optimize workouts for different goals such as endurance, tempo, threshold, VO2 max, and anaerobic capacity development.

4. Using the Calculator

Tips: Enter your FTP HR in beats per minute (bpm) and the desired percentage as a decimal between 0 and 1. All values must be valid (FTP HR > 0, percentage between 0-1).

5. Frequently Asked Questions (FAQ)

Q1: What is FTP HR?
A: Functional Threshold Power Heart Rate is the maximum average heart rate you can sustain for approximately one hour of cycling.

Q2: How do I determine my FTP HR?
A: The most accurate method is through a graded exercise test, but you can also estimate it from a well-paced 20-minute time trial effort.

Q3: What are typical cycling heart rate zones?
A: Common zones include: Zone 1 (50-60%), Zone 2 (60-70%), Zone 3 (70-80%), Zone 4 (80-90%), Zone 5 (90-100%).

Q4: Should heart rate zones change over time?
A: Yes, as your fitness improves, your FTP HR may increase, requiring recalibration of your training zones.

Q5: Are heart rate zones the same for everyone?
A: No, heart rate zones are highly individual and depend on factors like age, fitness level, genetics, and training history.
