Metabolic adaptations to endurance training : increased fat oxidation : an honors thesis [(HONRS 499)]
Endurance exercise training elicits physiological adaptations within the body. One of the adaptations observed with endurance training is the body's ability to oxidize increased amounts of fat as energy during exercise. A critical role in this energy substrate shift is mediated by the mitochondria. The mechanisms for adaptation at the mitochondria and their relative importance to the energy substrate shift will be overviewed. Further, the role of changes in hormone concentration will be discussed. These metabolic adaptations are two important mediators of the energy substrate utilized for muscular activity after a program of endurance training.
