Praxis 5857 Practice Question
Which of the following pairs of characteristics is used in the Karvonen method for calculating target heart rate zone?
Correct Answer: C
Rationale: The Karvonen method focuses on calculating target heart rate zones by incorporating age and resting heart rate. Age helps determine maximum heart rate, while resting heart rate is essential for assessing individual fitness levels.
Option A, weight and resting heart rate, is incorrect as weight is not a direct factor in this method. Option B, VO2 max and age, is not suitable since VO2 max is not used in the Karvonen calculation. Option D, resting heart rate and VO2 max, fails because VO2 max is irrelevant to this specific formula. Thus, age and resting heart rate are the key characteristics for accurately determining target heart rate zones.
