Christina's maximal absolute oxygen consumption (VO2max) is 1.4 L/min, and she weighs 122 lbs. What is her relative VO2max in ml/kg/min?

A. 2.58 ml/kg/min
B. 25.2 ml/kg/min
C. 38.6 ml/kg/min
D. 18.6 ml/kg/min

Answer :

The correct answer is option b) 25.2 ml/kg/min.The relative VO2max is a measure of maximal oxygen consumption adjusted for body weight. To calculate it, we need to convert Christina's weight from pounds to kilograms and then divide her absolute VO2max (in liters per minute) by her body weight in kilograms.

Given that Christina weighs 122 pounds, we can convert it to kilograms by dividing by 2.2046 (1 pound = 0.4536 kilograms). Therefore, her weight is approximately 55.45 kilograms.

Next, we divide her absolute VO2max of 1.4 L/min by her body weight of 55.45 kilograms. The result is approximately 0.0252 L/kg/min.

To convert liters to milliliters, we multiply by 1000. Therefore, Christina's relative VO2max is approximately 25.2 ml/kg/min.

Therefore, the correct answer is option b) 25.2 ml/kg/min.
