The physical fitness of athletes is measured by VO2 max,
Chapter , Problem 10.46(choose chapter or problem)
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?

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?
ANSWER:Problem 10.46The physical fitness of athletes is measured by “VO max”, which is the maximum volume of 2oxygen consumed by an individual during incremental exercise (for example, on a treadmill). Anaverage male has a VO max 2f 45 mL O /kg body 2ss/min, but a world-class male athletecan have a VO max2reading of 88.0 mL O /kg body 2ss/min. (a) Calculate the volume ofoxygen, in mL, consumed in 1 hr by an average man who weighs 185 lbs and has a VO max 2reading of 47.5 mL O /k2body mass/min. (b) If this man lost 20 lb, exercised, and increased hisVO max to 65.0 mL O /kg body mass/min, how many mL of oxygen would he consume in 1 hr 2 2 Step-by-step solution Step 1 of 3 The maximum volume of oxygen consumed by an individual during incremental exercise isdenoted by ‘V O2max’.For average male: 45 mLO 2V O 2max = kg body mass.minFor world class male athlete: 88.0 mLO 2V O max = kg body mass.min 2
