Document Summary

Aerobic component- very few stoppages in play, continuous action. Vo2 max- 45 ml/kg/min for heavy front row players to 65 ml/kg/min for 2nd row and back players. 750 times per player per match (3-4s: carbohydrates. Forms atp after a few seconds of high energy exercise. Glycolysis: breakdown of glucose to pyruvic acid (pyruvate) Gluconeogenesis: the formation of glucose from protein or fat (pyruvate, lactate and glycerol) Cytosol- atp-pcr reaction is happening and glycolysis. At rest, insulin brings down glucose concentration in the blood: activates glut 4 carriers, migrate to membrane between blood vessel and cytoplasm, enables glucose to enter the cell. Non exercise situation- glucose gets stored as glycogen (ex. laying around after dinner) If glucose concentration in blood starts to drop, glucagon is released, stimulates glucose release from the liver. Exercise situation- activates glut 4 carriers- independent from insulin: releasing glycogen into glycolytic pathway. Both activate glut 4 carriers through different stimuluses" (insulin and exercise)
