Document Summary
Energy: neither created nor destroyed, it is transformed, transforming: going from one energy source to another, source of energy: sun-> fusion of h atoms to give he, this reaction releases a great amount of heat and energy. 2 factors affecting energy production: total energy demand coupled with rate of demand. Energy system used is dictated by how fast energy is being produced related to specific power output production. Different energy systems are critical at different times (sprint = atp-pcr for fast energy production) Metabolic pathways = biological pathways that release energy in the form of atp. Shortest exercise duration = generate higher power output. Changes in power output are related to the rate of atp production by different energy systems: longer you go = more aerobic activity. Anytime you have a decrease in duration of exercise (shorter ex), you are capable of having an increase in speed of activity related to recruitment of particular system.
