2. The participant was measuring his VO2max on a typical running machine. His weight is 64.7kg. Peak measures are: VO2max(67ml/kg/min). And the highest VO2 is 4.3L/min. Calculate the subject’s absolute and relative O2max scores

Expert Solution

bsolute VO2 reflects the total (absolute) amount of oxygen consumed by a body, regardless of size, age or gender whereas relative VO2 indicates that score corrected to some reference, which happens to be a unit of mass or one kilogram (1 kg.). The units of measurement are all metric:

Absolute VO2 = Liters per min (L/min)

= 4.3L/min

Relative VO2 = milliliters per minute per kilogram (a unit of mass) which is rewritten as milliliters per kilogram per minute or mL/kg/min (1,000 mL = 1.0 L).

Relative VO2 =Absolute VO2 *1000/Weight of the person

4.3L/min *1000/64.7 = 66.4ml /min /kg

Both absolute and relative VO2 provide valuable information. Considering the role of oxygen in metabolism (i.e., to burn fuels) quantifying the total amount of oxygen consumed provides an estimate of calories expended.

Constant-volume calorimeters are sometimes calibrated by running a combustion reaction of known ΔE and measuring the change in temperature. For example, the combustion energy of glucose is 15.57 kJ/g. When a 2.000 g sample of glucose burns in a constant volume calorimeter, the calorimeter temperature increases from 21.45 to 23.34°C. Find the total heat capacity of the calorimeter (in kJ/K).
