CORE 2. Flashcards
Energy systems: ATP/PC: Source of fuel
Creatine phosphate
Energy systems: ATP/PC: Efficiency of ATP production
Very quick production but for a limited time
Energy systems: ATP/PC: Duration that the system can operate
0-10 seconds of high intensity activity, 90%+MHR
Energy systems: ATP/PC: Cause of fatigue
Limited stores of ATP and PC. Depletion of creatine phosphate
Energy systems: ATP/PC: By-products
heat
Energy systems: ATP/PC: rate of recovery
50% recovered in 30 seconds fully recovered in approx 2 minutes
Energy systems: ATP/PC: Process of recovery
Activity intensity decreases or ceases. Increased breathing rate as PC is replenished in the presence of oxygen
Energy systems: ATP/PC: Sporting examples
100m sprint, shot put,
is ATP/PC aerobic or anaerobic?
anaerobic
other name of ATP/PC system
alactacid
Energy systems: LACTIC ACID: Source of fuel
Carbohydrate stored in the muscle and liver as glycogen and glucose in the blood
Energy systems: LACTIC ACID: Efficiency of ATP production
Quick ATP production but fatigues drastically as lactic acid levels increase
Energy systems: LACTIC ACID: Duration that the system can operate
10 seconds to 2/3 minutes of relatively high intensity activity, 85%+ MHR
Energy systems: LACTIC ACID: Cause of fatigue
The cause of fatigue in the lactic acid system is the build-up of pyruvic acid in the muscle which is caused by production of lactate exceeding dispersal, this results in an increase in the Hydrogen ion in the muscle which causes fatigue
Energy systems: LACTIC ACID: By-products
Lactate/ lactic acid (Hydrogen ion)
Energy systems: LACTIC ACID: rate of recovery
30 minutes to two hours, will depend on level of lactate that has built up
Energy systems: LACTIC ACID:Process of recovery
Activity intensity decreases or ceases. Increased breathing rate as lactic acid is broken down in the presence of oxygen
Energy systems: LACTIC ACID: Sporting examples
200m sprint, 400m sprint
Energy systems: Another name for lactic acid system
Anaerobic glycolysis
Energy systems: is lactic acid system aerobic or anaerobic?
anaerobic
Energy systems: AEROBIC: Source of fuel
Carbohydrates stored in muscles and liver as glycogen, fats and occasionally protein
Energy systems: AEROBIC: Efficiency of ATP production
Slower ATP production but an endless supply, depending on intensity of exercise
Energy systems: AEROBIC: Duration that the system can operate
Endless supply at low to moderate levels of intensity, 60-85%MHR
Energy systems: AEROBIC: Cause of fatigue
Depletion of glycogen levels and fat stores, reliance on fat as a fuel
