down DATA ANALYSIS 1. Typical resting heart rates range from 55-100 beats per minute. What was the subject's resting heart rate? How much did the subject's heart rate increase above resting rate with exercise? What percent increase was this? Explain. alt 2. How does the subject's maximum heart rate compare with other students in the group or class? Is this what you expected? Explain. Explain- 3. Recovery time has been shown to correlate with degree of physical fitness. How does the subject's recovery rate compare to that of your classmates? Is this what you expected? page 94 4. Congestive heart failure is a condition in which the strength of contraction with each beat may be significantly reduced. For example, the ventricle may pump only half the usual volume of blood with each beat. Would you expect a person with congestive heart failure to have a faster or slower heart rate at rest? With exercise? 5. Certain medications are prescribed by medical professionals to slow a patient's heart or speed it up. If a patient complains of feeling poorly and has a heart rate of 120 beats/min, should a doctor administer a medicine to slow the rate? EXTENSIONS 1. Design an experiment to test whether duration of exercise affects recovery rate. You might have subjects exercise for 5, 10, or 15 minutes at a time and compare the time it takes for heart rate to return to baseline. 2. Design an experiment to test whether body position post-exercise affects recovery rate. What did your coach in high school tell you?
