Document Summary
Knes 373 lecture 24 aerobic training adaptations (cont"d) Reduced glycogen use after training: some adaptations suit both purposes. Less glycogen utilization, which shows lower reliance on glycogen during exercise: glycogen is our primary source of energy for exercise. If we reduce glycogen breakdown, we must also be reducing lactate accumulation. Ldh decreases after 31 days (less lactate being produced) participants les slikely to produce lactate. Pre-post training changes in lactate threshold: after training, our lactate response is delayed and the curve is shifted right, producing less lactate at exercise intensities compared to before training began. 1968 - effects of 21 days bed rest and subsequent. Does the heart change size that rapidly: reduction in blood volume. In the long term we also see less capability for oxygen extraction (a-vo2 difference) Muscle enzyme changes with detraining: even after training, trained individuals tend to have higher levels of these enzymes that non-trained individuals.
