What is the target heart rate zone (70-85%) for a 60-year-old?

What is the target heart rate zone (70-85%) for a 60-year-old?

• A. 90 bpm to 110 bpm
• B. 100 bpm to 151 bpm
• C. 122 bpm to 156 bpm
• D. 112 bpm to 136 bpm

Answer: (D)

To determine the target heart rate zone for a 60-year-old, we first need to calculate the appropriate maximum heart rate and then apply the percentages for the target zone. The maximum heart rate is commonly estimated using the formula: 220 minus the individual’s age. For a 60-year-old, the estimated maximum heart rate would be: 220 - 60 = 160 bpm. Next, we calculate 70% and 85% of this maximum heart rate: - 70% of 160 bpm is 112 bpm. - 85% of 160 bpm is 136 bpm. Therefore, the target heart rate zone for a 60-year-old would be from 112 bpm to 136 bpm, which aligns with the option that indicates this range. This is the correct answer, as it appropriately incorporates the age-related maximum heart rate calculation along with the specified intensity levels for exercise, ensuring that the individual is training within a safe and effective heart rate zone for cardiovascular benefits.

The maximum heart rate is commonly estimated using the formula: 220 minus the individual’s age. For a 60-year-old, the estimated maximum heart rate would be:

220 - 60 = 160 bpm.

Next, we calculate 70% and 85% of this maximum heart rate:

• 70% of 160 bpm is 112 bpm.

• 85% of 160 bpm is 136 bpm.

Therefore, the target heart rate zone for a 60-year-old would be from 112 bpm to 136 bpm, which aligns with the option that indicates this range. This is the correct answer, as it appropriately incorporates the age-related maximum heart rate calculation along with the specified intensity levels for exercise, ensuring that the individual is training within a safe and effective heart rate zone for cardiovascular benefits.
