Answer :

Final answer:

To convert 4.5 L/min to METs for a 165 lb man, we first need to convert the liters to milliliters, then calculate the METs using the formula METs = VO2 / 3.5. The correct answer is approximately 1,285.71 METs, which is not provided in the given options.

Explanation:

To convert 4.5 L/min to METs for a 165 lb man, we need to know the formula for calculating METs. METs, or metabolic equivalents, are a way to measure the intensity of physical activity based on the resting metabolic rate. The formula for calculating METs is METs = VO2 / 3.5, where VO2 is the oxygen consumption rate in milliliters per kilogram of body weight per minute.

To convert 4.5 L/min to METs, we need to convert it to milliliters per kilogram of body weight per minute. To do this, we need to know the weight of the man in kilograms. Let's assume the weight of the man is 75 kg. The equation for converting liters to milliliters is 1 liter = 1000 milliliters. So, 4.5 L/min = 4500 mL/min. Now, we can calculate the METs:

METs = VO2 / 3.5 = (4500 mL/min) / (3.5 mL/kg/min)

Now, we need to convert the weight of the man from pounds to kilograms. 1 pound is approximately 0.45 kilograms. So, 165 lb = 74.8 kg. Now we can calculate the METs:

METs = (4500 mL/min) / (3.5 mL/kg/min) = 1285.71

So, the answer is not given among the options provided. The correct answer is approximately 1,285.71 METs.
