Flashcards
Energy systems
Cards in this deck (18)
- 1What is the fuel source of the ATP-PC system?Creatine phosphate (CP)
- 2What is the duration of the ATP-PC system?10-12 seconds of high intensity movements
- 3What causes fatigue in the ATP-PC system?Depletion of creatine phosphate supplies
- 4What is the by-product of the ATP-PC system?Heat
- 5What is the recovery time for the ATP-PC system?2 minutes
- 6What type of pathway is the ATP-PCAnaerobic (no oxygen)
- 7What is the fuel source for the Lactic acid system?Carbs, which are then converted into glucose, then transported by blood into the muscles, creating glycogen
- 8What is the duration of the lactic acid system?10 seconds to 3 minutes of high intensity movements
- 9What causes fatigue in the lactic acid system?Built up lactic acid, as it stops muscle contraction
- 10What is the by product in the lactic acid system?Lactic acid
- 11what is the recovery time of the lactic acid system?30 mins to 2 hours
- 12What type of pathway is the lactic acid system?Anaerobic (no oxygen)
- 13What is the fuel source of the aerobic system?First carbs (glucose), then fats (lipids) and finally protein after carbs and fats are fully depleted?
- 14What is the duration of the aerobic system?From 3 minutes up to multiple hours
- 15What causes fatigue in the aerobic system?No glycogen, lactic acid build up and dehydration
- 16What is the by product of the aerobic energy system?Carbon dioxide and water
- 17What is the recovery time for the aerobic system?2-3 days
