1. What is Resting Heart Rate?

Resting Heart Rate (RHR) is the number of times your heart beats per minute while at complete rest. It's a key indicator of cardiovascular health and fitness level.

2. How Does Garmin Calculate RHR?

Garmin uses a specific method to calculate resting heart rate:

This method identifies the lowest average heart rate over any 30-minute period during a 24-hour monitoring period, providing a more accurate measurement than single-point measurements.

3. Importance of Monitoring RHR

Details: Tracking your resting heart rate can help monitor fitness progress, detect potential health issues, and assess recovery status. A lower RHR typically indicates better cardiovascular fitness.

4. Using the Calculator

Tips: Enter your heart rate data collected over 24 hours as comma-separated values. For accurate results, provide at least 48 data points (one every 30 minutes).

5. Frequently Asked Questions (FAQ)

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

Q2: Why does Garmin use the lowest 30-minute average?
A: This method captures your true resting state, typically during deep sleep, providing a more accurate measurement than awake measurements.

Q3: When is the best time to measure RHR?
A: RHR is most accurate when measured first thing in the morning before getting out of bed, but Garmin's 24h monitoring provides a more comprehensive assessment.

Q4: What factors can affect RHR?
A: Factors include fitness level, stress, medications, caffeine, temperature, and body position during measurement.

Q5: When should I be concerned about my RHR?
A: Consult a healthcare provider if your RHR is consistently above 100 bpm (tachycardia) or below 60 bpm (if not an athlete) with symptoms like dizziness or fatigue.
