Document Summary

It"s not different methods turning on and off, it"s just that they can all go and the cell will just grab whatever atp is there. Cardio is just being super efficient, burning the sugar and glycogen in the muscles. Make muscle work super hard, produce lactic acid. Afterword, burn the fats to oxidatively get rid of the lactic acid debt. High intensity is only for a short period of time. Fast twitch type 2, turn on fast for short output. Anaerobic glycolysis, fast energy to keep speed up i. Ion disturbances, lactic acid build up, lots of imbalances. When you"re exercising, the oxygen consumption goes way up. After exercising, oxygen consumption is still super high. Go to liver to be turned into glucose. Limited by o2 into being delivered to the mitochondria. Limited by rate of delivery and availability of foods. Stores of fat out weight stores of sugar. Depletion of muscle glycogen, changes in activity of muscle protein.
