If a young woman consumes 1,200 ml of O₂ in a six-minute basal metabolic rate test period, her BMR is

Quizplus · Accepted Answer

The formula for calculating BMR in kcal/hour is:

BMR = (VO2 x 1000) x 5 kcal/L

Where VO2 is the volume of oxygen consumed in one minute, multiplied by 1000 to convert it from mL to L. Multiply by 5 to convert from kcal/L/min to kcal/hour.

Therefore, to find the BMR, we need to know the volume of oxygen consumed in one minute. Since the young woman consumed 1,200 mL of oxygen in six minutes, we need to divide this by six to get the volume consumed in one minute.

1,200 mL / 6 minutes = 200 mL/min

Now we can plug this value into the formula:

BMR = (200 x 1000) x 5 kcal/L
BMR = 1,000,000 x 5 kcal/hour
BMR = 5,000,000 kcal/hour
BMR = 57.6 kcal/hour (rounded to one decimal place)

Therefore, the best answer is B.
