Using the HR max formula, what is the HR max for age 30?

• A. 183
• B. 186
• C. 190
• D. 200

Answer: (B)

Estimating maximum heart rate with age-based formulas is the idea here. A commonly used modern equation is HRmax = 206.9 − 0.67 × age. Plugging in age 30 gives 206.9 − (0.67 × 30) = 206.9 − 20.1 ≈ 186.8 bpm. That rounds to about 187 bpm, so the value closest to that among typical options is 186 bpm. Therefore, 186 bpm is the best match for a 30-year-old using this formula. If you had used the older 220 − age rule, you’d get 190 bpm, but that’s a different standard. Remember these estimates are approximate guides for setting training zones.
