Process of Science How Is Cardiovascular Fitness Measured? 5 Points Questions 1. What does a blood pressure measurement of 110/70 mean? (In other words, what do the top and bottom numbers refer to)? What is happening in the heart? (2 pts). The top number is the highest of both numbers. This number is the systolic pressure. This measures pressure in your arteries when your heart beats (heart is contacting). The bottom number is the diastolic pressure. The diastolic blood pressure measure the pressure in the arteries between heartbeats (heart muscle is resting). A health blood pressure is when the systolic number is not greater than 120 and the diastolic number is less than 80. 2. What is your resting heart rate? How did you determine this number? (1.5 points) For adults the normal resting heart rate ranges from 60 – 100 beats a minute. The lower the heart rate the more efficient it is to function. To measure your heart rate you would check your pulse. Place your index finger alongside of your neck (near the windpipe) or you check your pulse on your wrist by placing two fingers when you locate your pulse count the number of beats within 15 seconds then multiple by 4. I tested my heart beat. 22 beats times 4 = 88 beats per minutes. 3. Which of the following resting pulse and resting blood pressure results would be typical of a well-conditioned athlete? Explain your answer (1.5 points) 72 and 150/90; 48 and 110/80; 66 and 120/95; 84 and 110/75. Athletes tends to have a lower resting heart rate because of their intense training programs. Their training programs conditions their heart muscle to pump greater blood volume. The well-conditioned athlete would have a resting pulse of 48 and
