1. What is Maximum Heart Rate?

Definition: Maximum heart rate (Max HR) is the highest number of beats per minute your heart can reach during maximum physical exertion.

Purpose: Knowing your Max HR helps determine appropriate exercise intensity levels for cardiovascular training.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Max HR — Maximum heart rate in beats per minute (bpm)
• age — Your current age in years

Explanation: This age-based formula provides a general estimate of your maximum safe heart rate.

3. Importance of Knowing Your Max HR

Details: Understanding your Max HR helps you:

• Set safe and effective exercise intensity
• Calculate target heart rate zones for different training goals
• Monitor workout intensity
• Avoid overexertion during exercise

4. Using the Calculator

Tips: Simply enter your age in years (must be between 1-120). The calculator will estimate your maximum heart rate.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the 220-age formula?
A: It's a general estimate. Individual variations exist, and newer research suggests alternative formulas may be more accurate for some populations.

Q2: What are typical target heart rate zones?
A: Common zones are:

• 50-60% Max HR: Very light, warm-up/cool-down
• 60-70% Max HR: Light, fat burning
• 70-80% Max HR: Moderate, aerobic
• 80-90% Max HR: Hard, anaerobic
• 90-100% Max HR: Maximum effort

Q3: Are there alternative Max HR formulas?
A: Yes, some alternatives include:

• Tanaka: 208 - (0.7 × age)
• Gulati (for women): 206 - (0.88 × age)

Q4: Should I exercise at my maximum heart rate?
A: Generally no - maximum heart rate is a theoretical limit. Most training occurs at 50-85% of Max HR.

Q5: Can medications affect my Max HR?
A: Yes, certain medications (like beta blockers) can lower your Max HR. Consult your doctor for personalized advice.
