Document Summary
Knes 373 lecture 14 integrated energy systems. Is activated almost as soon as atp resynthesis is required pcr (used to resynthesize atp almost immediately: breaks down muscle glycogen for rapid atp resynthesis glycolysis (much faster than aerobic processes) In a 30-s sprint, does atp get resynthesized aerobically: yes, there will be some aerobically synthesized atp. Integration of energy systems, all of the time: without very complex calculations, it is very difficult to determine exactly how much energy is being supplied from each of the energy systems. Surprising similarity in pattern of exercise: an approximate law of fatigue in the speeds of racing animals, horses running, pacing horses in harness, humans running, humans. For 200-m compared to 100-m, 200-m average speed will come out faster because the start up time is proportionately less and thus the peak speed will be more impactful on the average. It also implies something about the underlying energy systems.
