Question

alex is committed to maintaining his health through regular exercise and has a routine that goes beyond simply monitoring his heart rate. after completing his intensive running sessions, he checks his recovery heart rate and takes the time to measure his post - exercise blood pressure. this additional step is part of his comprehensive approach to track his cardiovascular health. why is this additional step necessary?
○ to ensure that his blood pressure returns to a normal range after exercise
○ to check the functionality of his heart rate monitor by comparing different health metrics
× to confirm that he has burned a sufficient number of calories
○ to determine that he has reached his maximum oxygen uptake during his running session

Explanation:

To solve this, we analyze each option:

• Option 1: Measuring post - exercise blood pressure helps check if blood pressure returns to normal range after exercise, which is part of tracking cardiovascular health.
• Option 2: Measuring blood pressure isn't for checking the heart rate monitor's functionality.
• Option 3: Blood pressure measurement doesn't confirm calorie burn.
• Option 4: Blood pressure measurement isn't related to maximum oxygen uptake.

Answer:

A. to ensure that his blood pressure returns to a normal range after exercise
