Question

1) Is an individual more or less efficient when cylcing at the same power output outdoors on a mountain bike as compared to indoors on a stationary cycle? Why?

2) An individual perfomed 1000 J of work. At a certain point in time their VO2 was 2.62 L/min and VCO2 was 2.58 L/min. Calculate their Gross Mechanical Efficiency at this time? (1 kcal = 4186 J)

3) If resting energy production was V02 0.3 L/min and CO2 0.25 L/min what would be the net mechanical efficincy from question #2?

4) What is work to rest ratio?
