Lab 7: Exercise Physiology Weekly Assignment (SS15) 100pts 1. A. What did you hypothesize would happen to oxygen consumption and carbon dioxide during the sequential 2 min stages of aerobic cycling at progressively higher resistances during the VO 2 max test? (2.5pts) I hypothesized that the oxygen consumption and carbon dioxide production would increase during the 2 minute stages of aerobic cycling at progressively higher resistances. This would be at a linear correlation because according to the oxygen consumption graph, as the exercise proceeds, the oxygen uptake increases until the VO2 reaches a certain maximal value point after which it plateaus. B. What did you hypothesize would happen to energy expenditure when comparing various non-exercise activities (sitting, fidgeting, standing, and easy stair stepping)? Include the class data screen capture of NEAT activity. (5 pts) Figure 1: Using seated and still as a baseline value or a value in which to compare the rest of the conditions, respiratory rate significantly increased during seated and moving, standing and moving, and stepping, where stepping caused the greatest increase. Standing produced a similar respiratory rate to seated and still. Once again using seated and still as a baseline in which to compare, tidal volume increased significantly during seated and moving, standing and moving, and stepping conditions. The stepping condition created the largest increase in tidal volume. Standing produced a similar tidal volume value to seated and still. I hypothesized that there would be a significant difference in the energy expenditure when comparing the various non-exercise activities such as sitting, fidgeting, standing, and easy stair stepping because as an example, during easy stair stepping, there would be more muscle fiber activation than compared to the activation levels while simply being seated.
