Final answer:

To convert METs to absolute Vo2 for a 173 lbs 25-year-old male, first convert the weight to kg, then multiply the METs by the conversion factor (3.5 ml/kg/min), and finally multiply the Vo2 in ml/kg/min by the weight in kg. The result is approximately 2885.625 ml/min.

Explanation:

To convert METs to absolute Vo2, you can use the conversion factor of 3.5 ml/kg/min. This basically means that 1 MET is equivalent to the oxygen consumption of 3.5 ml per kg body weight per minute at rest. Therefore, to obtain the absolute Vo2 from MET values:

  1. First, convert the weight from lb to kg. 1 lb equals to approximately 0.4536 kg. So, for a person who weighs 173 lbs, their weight in kg is 173 * 0.4536 = 78.5 kg (rounded to 1 decimal place).
  2. Next, use the METs value given and the conversion factor. Multiply the METs (10.5) by the conversion factor (3.5 ml/kg/min). The Vo2 in ml/kg/min is thus 10.5 * 3.5 = 36.75 ml/kg/min.
  3. Finally, to get the absolute Vo2 (which gives the total amount of oxygen consumed), you need to multiply the Vo2 in ml/kg/min by the weight in kg. So, the absolute Vo2 for this person is 36.75 * 78.5 = 2885.625 ml/min.
