Questions: Please write your answers underneath the questions in sentence/paragraph form (no bullet points). These answers should be in YOUR OWN words. Do not copy the answers from other laboratory students.

1. What was the steady-state O2 uptake during exercise for the low-intensity and high-intensity trials for treadmill running and cycling?

2. Calculate Absolute VO2 (average) to Kcal/min for sitting, exercise, and post-exercise for treadmill and cycling. You will need to calculate the average VO2 for sitting, exercise, and post-exercise. *Show calculations/conversions* Failure to do so will result in a loss of points

2. Graph time vs VO2 (ml/kg/min) for each test. Explain the differences between the two components of EPOC. What are the differences between a low-to-moderate intensity EPOC and high-intensity EPOC? ***Graph will need to be within the word document. Make sure to include the units***
