Problem 1: Provide several reasons for measuring VO2.
Problem 2: Explain why VO2 would change transitioning from sitting to jogging.
Problem 3: Predict how VO2 and RER would change if we transitioned from jogging to sprinting.
Problem 4: What was the average VO2 during passive sitting? Why are we consuming oxygen while at rest?
Problem 5: At minute 5 (end of passive sitting), what is the kcal/min and kcal/day energy expenditure? Show calculations and correct for RER.
Problem 6: At minute 5, what is the % contribution of carbohydrate and fat to energy expenditure? Does this seem logical? Why or why not?
Problem 7:
A) What happens to VO2 during exercise? Why? Describe the shape of the response in your answer. B) What happens to VE (ventilation) during exercise? Why?
Problem 8: At minute 10 (end of exercise), what is the kcal/min and kcal/hr energy expenditure? Show calculations and correct for RER. How could this information prove useful to us?
Problem 9: At minute 10, what is the % contribution of carbohydrate and fat to energy expenditure?
Problem 10: What would we expect kcal/min to be if we continued to cycle at the same work rate for an additional 30 minutes? Why?
