The Effect Of Low And High Carbohydrate Diets On Pulmonary Oxygen Uptake And Muscle Deoxygenation Kinetics During Exercise Transitions Into The Heavy-Intensity Domain, John Leckie
Electronic Thesis and Dissertation Repository
The purpose of this study was to determine the effects of a high carbohydrate (HCHO) and low carbohydrate (LCHO) diet on the adjustment of pulmonary oxygen (O2) uptake ( ) and muscle deoxygenation ([HHb]) during transitions to heavy intensity exercise. Young, healthy, male subjects aged (24+/-3) underwent a 4 day LCHO followed immediately by a 4 day HCHO diet, with each diet preceded by a glycogen depletion protocol. This protocol was designed to alter PDH activity. Subjects completed 3 step transitions to a work rate corresponding to 35% of the difference between their lactate threshold and peak for …
