What is the purpose of using the Heart Rate Reserve (HRR) Method, also known as the Karvonen method?
  1. To determine the amount of time someone should spend doing a particular exercise
  2. To determine training intensity based on the difference between someone’s predicted maximal heart rate and resting heart rate
  3. To determine what level or stage of training to start a client at
  4. To determine exercise intensity during training
Explanation
Answer - B - The purpose of using the Heart Rate Reserve Method is to determine training intensity based on the difference between someone’s predicted maximal heart rate (MHR) and resting heart rate (RHR). Choosing a predetermined Target Heart Rate (THR) is the most widely utilized and accepted way of establishing training intensity. The following formula describes how to calculate this value: THR = [(HRmax - HRrest) x desired intensity] + HRrest.
