6. Referring back to question 5, both Simon and Joe undergo an exercise stress test at their school’s human performance lab. During the test, each individual’s heart rate is monitored as they perform exercise to the point of exhaustion. At the peak power output before exhaustion, both Joe and Simon’s maximum heart rate reaches 195 bpm. Calculate each individual’s peak cardiac output, assuming that their stroke volumes are the same as at rest (look at problem 4). What does this mean to the overall health of each individual?
