Part I: Use the information below to answer the following questions:   Subject A: 80 kg VO2max = 54 ml/kg/min RER (respiratory exchange ratio (VCO2/VO2) ) @ 70% VO2max = 0.93 Subject B: 70 kg VO2max = 38 ml/kg/min RER @ 70% VO2max = 0.94   a) Who is burning more total kcals at 70% VO2max?   b) Who is burning more CHO kcals at 70% VO2max?   c) Who is burning more absolute CHO kcals at VO2max?   Part II: Using the information from question #2, calculate the grams of carbohydrates and the grams of lipids that each subject (A and B) is utilizing per minute at 70% VO2max.   3. You are running on the treadmill at the Rec Center and you overhear someone telling their friend that "you burn more absolute fat (kcal/hr) running at 5mph than you do at 7mph".

Question

Part I: Use the information below to answer the following questions:

 

Subject A: 80 kg VO2max = 54 ml/kg/min RER (respiratory exchange ratio (VCO2/VO2) ) @ 70% VO2max = 0.93 Subject B: 70 kg VO2max = 38 ml/kg/min RER @ 70% VO2max = 0.94

 

a) Who is burning more total kcals at 70% VO2max?

 

b) Who is burning more CHO kcals at 70% VO2max?

 

c) Who is burning more absolute CHO kcals at VO2max?

 

Part II: Using the information from question #2, calculate the grams of carbohydrates and the grams of lipids that each subject (A and B) is utilizing per minute at 70% VO2max.

 

3. You are running on the treadmill at the Rec Center and you overhear someone telling their friend that "you burn more absolute fat (kcal/hr) running at 5mph than you do at 7mph".
