Chapter 2.3, Problem 8E

Aerobic Power Aerobic power can be thought of as the maximum oxygen consumption attainable per kilogram of body mass. There are a number of ways in which physical educators estimate this. One method uses the Queens College Step Test. In this test, males step up and down a 16-inch bleacher step 24 times per minute for 3 minutes, and females do 22 steps per minute for 3 minutes. Five seconds after the exercise is complete, a 15-second pulse count $P$ is taken. Maximum oxygen consumption $M$, in milliliters per kilogram, for males is approximated by $M=111.3-1.68P.$

For females, the recommended formula is $F=65.81-0.74P.$

a. Calculate the maximum oxygen consumption for both a male and a female who show a 15-second pulse count of 40.

b. What 15-second pulse count for a male will indicate a maximum oxygen consumption of 35.7 milliliters per kilogram?

c. What 15-second pulse count will indicate the same maximum oxygen consumption for a male as for a female?

d. What maximum oxygen consumption is associated with your answer in part c?
