1. What is Maximum Heart Rate?

Maximum heart rate (Max HR) is the highest heart rate an individual can achieve during maximal physical exertion. For seniors, it's often recommended to exercise at 85% of this maximum for safety.

2. How Does the Calculator Work?

The calculator uses the standard maximum heart rate formula:

And provides an adjusted value for seniors:

Where:

• \( Age \) — Person's age in years (65-120 for seniors)
• \( 0.85 \) — Recommended percentage of max HR for seniors

Explanation: The formula estimates age-related decline in maximum heart rate capacity.

3. Importance of Heart Rate Calculation

Details: Knowing your maximum heart rate helps determine safe exercise intensity levels, especially important for seniors to avoid overexertion.

4. Using the Calculator

Tips: Enter age in years (must be 65 or older). The calculator will show both maximum heart rate and the recommended adjusted rate for seniors.

5. Frequently Asked Questions (FAQ)

Q1: Why adjust to 85% for seniors?
A: Seniors often have reduced cardiovascular capacity, so exercising at full maximum heart rate may be unsafe.

Q2: Is this formula accurate for everyone?
A: It's an estimate. Individual variations exist based on fitness level, medications, and health conditions.

Q3: When should I measure my heart rate?
A: Measure during or immediately after exercise for most accurate readings.

Q4: Are there limitations to this formula?
A: Less accurate for very fit individuals or those on heart rate-affecting medications.

Q5: Should I consult a doctor about my target heart rate?
A: Yes, especially if you have heart conditions or are starting a new exercise program.
