Question: Using the following data, calculate the target heart rate zone (threshold heart rate and target ceiling heart rate) using the percent of heart rate reserve (% HRR) method. Make sure you include units (beats per minute) and round to the nearest whole number. Hints: max HR = 220 - age; use threshold of 60% and ceiling of 80% Heart rate reserve (HRR) = max HR - resting HR Data: Keenan, age 16 years, resting HR = 57
To calculate Keenan's target heart rate zone using the percent of heart rate reserve method, we need to first calculate his maximum heart rate and heart rate reserve. Max HR = 220 - age Max HR = 220 - 16 Max HR = 204 Heart Rate Reserve = Max HR - Resting HR HRR = 204 - 57 HRR = 147 Threshold Heart Rate: Target Heart Rate = (HRR x % intensity) + Resting HR THR = (147 x 60%) + 57 THR = 123 Target Ceiling Heart Rate: Target Heart Rate = (HRR x % intensity) + Resting HR TCHR = (147 x 80%) + 57 TCHR = 180 Therefore, Keenan's threshold heart rate is 123 bpm and his target ceiling heart rate is 180 bpm. He should aim to keep his heart rate within this range during exercise to achieve the desired intensity level.
