Maximum Heart Rate (MHR):
| From: | To: |
Maximum Heart Rate (MHR) is the highest number of beats per minute (bpm) your heart can reach during maximum physical exertion. It represents the upper limit of what your cardiovascular system can handle during exercise.
MHR is typically measured during a graded exercise test under medical supervision:
This is considered the gold standard method for determining an individual's true maximum heart rate.
Details: Knowing your MHR is essential for establishing accurate heart rate training zones, optimizing exercise intensity, and ensuring safe and effective workouts. It's particularly important for athletes and individuals with specific training goals.
Tips: Enter the peak heart rate observed during your most recent exercise test. This value should be obtained from a medically supervised stress test for the most accurate results.
Q1: How is MHR different from age-predicted maximum heart rate?
A: Age-predicted formulas (like 220-age) provide estimates, while measured MHR from exercise testing gives your actual maximum heart rate, which can vary significantly from population averages.
Q2: Why is measured MHR more accurate than formulas?
A: Individual variations in genetics, fitness level, and other factors mean age-based formulas can be off by 10-20 bpm in many individuals.
Q3: How often should MHR be measured?
A: MHR remains relatively stable in adults, but may decrease slightly with age. Retesting every 2-3 years or after significant changes in fitness level is recommended.
Q4: Are there safety concerns with MHR testing?
A: Maximum exertion testing should always be conducted under medical supervision, especially for individuals with known heart conditions or risk factors.
Q5: Can medications affect MHR?
A: Yes, certain medications (like beta-blockers) can lower maximum heart rate. Always inform your healthcare provider about medications before testing.
