Document Summary
Long duration and low intensity (60% vo2 max or lower) fat is predominantly. Absolute and relative utilization of carbs increase when go from mid to high intensity. Absolute fat level utilization goes up from low to medium more utilization of fatty acids. Absolute rate of fat oxidation goes down from medium to high. One metabolic change that will occur in reference to aerobic training. Increased oxidative enzymes (citrate synthase (takes acetyl coa in tca), Increase mito content: 50-100% increase (about doubles) in three months in training, when vo2 max only goes up 10, cant go higher than doubling because of space when increase mito content, it takes away from space of others. Heart where it is oxidized as fuel for atp. Inactive skeletal muscles to be made into pyruvate. Pyruvate needs to go into the mitochondria, and undergo activity of pyruvate dehydrogenase complex. Vo2 and vo2 max testing and oxygen uptake.
