1. What is Resting Heart Rate (RHR)?

Resting Heart Rate (RHR) is the number of times your heart beats per minute while at complete rest. It's an important indicator of cardiovascular health and fitness level, with normal ranges typically between 60-100 bpm for adults.

2. How Does the Calculator Work?

The calculator provides an approximation of resting heart rate based on demographic factors:

Where:

• Baseline RHR — Approximately 70 bpm
• Age — Older age may slightly increase RHR
• Weight — Higher weight/BMI may increase RHR
• Height — Used for BMI calculation

Explanation: This provides a general approximation. Actual RHR can vary based on fitness level, genetics, and other health factors.

3. Importance of RHR Monitoring

Details: Monitoring resting heart rate helps assess cardiovascular health, track fitness progress, and identify potential health issues. Lower RHR generally indicates better cardiovascular fitness.

4. Using the Calculator

Tips: Enter age in years, weight in kilograms, and height in centimeters. All values must be valid positive numbers for accurate approximation.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal resting heart rate?
A: For adults, normal RHR ranges from 60-100 bpm. Well-trained athletes may have RHR as low as 40-60 bpm.

Q2: How does age affect resting heart rate?
A: RHR tends to increase slightly with age due to changes in cardiovascular efficiency and overall fitness.

Q3: Can weight affect resting heart rate?
A: Yes, higher body weight typically requires the heart to work harder, potentially increasing RHR.

Q4: When is the best time to measure RHR?
A: Measure first thing in the morning while still in bed, before any physical activity or caffeine consumption.

Q5: Should I be concerned about my RHR?
A: Consult a healthcare professional if your RHR is consistently above 100 bpm (tachycardia) or below 60 bpm (bradycardia) without being an athlete.
