1. What is Target Heart Rate?

Target Heart Rate (THR) is the desired heart rate range during exercise that indicates the appropriate intensity level for cardiovascular training. For children, this helps ensure safe and effective physical activity.

2. How Does the Calculator Work?

The calculator uses the standard formula:

Where:

• \( Age \) — Child's age in years
• \( Intensity \) — Desired exercise intensity as a percentage

Explanation: The formula estimates maximum heart rate (220 - Age) and then calculates the target range based on the desired intensity level.

3. Importance of Target Heart Rate

Details: Monitoring heart rate during exercise helps children exercise at an appropriate intensity for their fitness goals, whether for general health, weight management, or athletic training.

4. Using the Calculator

Tips: Enter the child's age in years (typically 4-18 for this calculator) and the desired exercise intensity as a percentage (typically 50-85% for moderate to vigorous exercise).

5. Frequently Asked Questions (FAQ)

Q1: Is this formula appropriate for all children?
A: While widely used, individual variations exist. Children with health conditions should consult a healthcare provider before starting an exercise program.

Q2: What intensity level is recommended for children?
A: For general fitness, 50-70% of maximum heart rate is recommended. For more vigorous training, 70-85% may be appropriate.

Q3: How accurate is the 220-age formula?
A: It's a general estimation. Individual maximum heart rates can vary by ±10-15 beats per minute.

Q4: Should children exercise at high intensities?
A: Children can safely participate in vigorous activity, but it should be age-appropriate and include proper warm-up and cool-down periods.

Q5: How can I measure my child's heart rate during exercise?
A: Use a heart rate monitor or manually measure pulse at the wrist or neck for 15 seconds and multiply by 4.
