core 2 - energy systems Flashcards
source of fuel for ATP/CP system
CP
source of fuel for lactic acid system
glycogen, more specifically carbs –> glucose –> glycogen
source of fuel for aerobic system
carbohydrates, fatty acids and amino acids
efficiency of ATP/CP system
ATP rapidly made but it has a very limited source of fuel. 0.7 ATP per reaction
efficiency of Lactic acid system
ATP rapidly made, not as fast as ATP/CP system, but production requires large quantities of glucose
efficiency of Aerobic system
slow but more supply of ATP readily available
duration of lactic acid system
30 sec - 3 min depending on intensity
duration of ATP/ CP system
10-12 secs high intensity movement
cause of fatigue for ATP/CP system
depletion of CP
duration of aerobic system
endless supply
cause of fatigue for lactic acid system
lactic acid
cause of fatigue for aerobic system
depletion of glycogen levels and fat stores
by products of ATP/ CP system
none
by products of lactic acid system
pyruvate OR lactic acid
by products of aerobic system
CO2 , heat and water
rate of recovery of ATP/CP system
50% recovered in 30 secs, fully recovered by 2 mins
rate of recovery of lactic acid system
30 mins - 2 hrs
rate of recovery of aerobic system
food must be eaten to replenish energy stores, 50 to 100 grams of carbohydrates within 30 minutes of exercise. recovery can take a full day
examples of ATP/ CP system
100 m sprint, kicking a ball in rugby
examples of lactic acid system
200 m swim, repeated tackles in rugby
examples of aerobic system
activity that lasts longer than 3 mins ( 1500m swim)
aerobic means
rhythmic and repetitive. It increases your heart rate and how much oxygen your body uses.
anaerobic
“Anaerobic” means “without oxygen”. intense and short-duration, relying on energy production without oxygen.
