Final answer:
To find the weight of the man, we divide his absolute VO2max in liters per minute by his predicted VO2max in ml/kg/min, after converting to the same units. The calculation reveals that his weight is approximately 70 kilograms.
Step-by-step explanation:
The question asks for the weight of a 42 year-old male with a predicted VO2max of 50.43 ml/kg/min and an absolute VO2max of 3.53 L/min. To calculate his weight, we use the formula:
Absolute VO2max (L/min) = (Predicted VO2max (ml/kg/min) * Weight (kg)) / 1000
Re-arranging the formula to solve for weight:
Weight (kg) = Absolute VO2max (L/min) * 1000 / Predicted VO2max (ml/kg/min)
Plugging the values into the equation:
Weight (kg) = 3.53 L/min * 1000 / 50.43 ml/kg/min
Weight (kg) = 3530 / 50.43
Weight (kg) = 70 kg (rounded to the nearest kg)
Therefore, the man weighs approximately 70 kilograms.
