ratio of quads to hams is
3 quads 2 hams
which energy sx is used for ATP production during high intensity, super short duration exercise like sprinting 100 meters (up to 15 sec).
ATP-PC (phosphocreatine decomposes)
ATP and PC are stored
within contractile tissue
anaerobic metabolism is aka
lactic acid sx
this energy sx is used for shorter duration higher intensity exercise like sprinting 500meters
anaerobic glycolosis
in this energy system, stored glycogen is split into glucose then glycolosis occurs creating pyruvic acid, then ATP.
anaerobic glycolosis (or lactic acid sx)
anaerobic glycolosis only uses what to make energy
carbs (glycogen and glucose)
which energy sx yields the most ATP
aerobic, but it requires many complex chemical rxns
