The physical fitness of athletes is measured by “VO2 max,”which is the maximum volume of oxygen consumed by anindividual during incremental exercise (for example, on atreadmill). An average male has a VO2 max of 45 mL O2>kgbody mass/min, but a world-class male athlete can have a VO2max reading of 88.0 mL O2>kg body mass/min. (a) Calculatethe volume of oxygen, in mL, consumed in 1 hr by an averageman who weighs 185 lbs and has a VO2 max reading of 47.5mL O2>kg body mass/min. (b) If this man lost 20 lb, exercised,and increased his VO2 max to 65.0 mL O2>kg body mass/min,how many mL of oxygen would he consume in 1 hr?

Question

The physical fitness of athletes is measured by “VO2 max,”
which is the maximum volume of oxygen consumed by an
individual during incremental exercise (for example, on a
treadmill). An average male has a VO2 max of 45 mL O2>kg
body mass/min, but a world-class male athlete can have a VO2
max reading of 88.0 mL O2>kg body mass/min. (a) Calculate
the volume of oxygen, in mL, consumed in 1 hr by an average
man who weighs 185 lbs and has a VO2 max reading of 47.5
mL O2>kg body mass/min. (b) If this man lost 20 lb, exercised,
and increased his VO2 max to 65.0 mL O2>kg body mass/min,
how many mL of oxygen would he consume in 1 hr?
