(31 cards)
Fats yield
higher
Fats rate
lower
Carbohydrates yield
lower
Carbohydrates rate
higher
Preferred fuel source
carbohydrates because easier to break down and requires less oxygen
ATP-PC duration
10sec
ATP-PC peak
5sec
ATP-PC cause of fatigue
depletion of CP and stored ATP
ATP-PC recovery
passive; 30 sec 50%, 3min full
Anaerobic Glycolysis duration
10-60sec
Anaerobic Glycolysis peak
30sec
Anaerobic Glycolysis cause of fatigue
build up of by-products
Anaerobic Glycolysis fuel source
carbohydrates
Anaerobic Glycolysis recovery
active
Aerobic yield
highest
Aerobic rate
slowest
Aerobic duration
60sec +
Aerobic cause of fatigue
using fats as major fuel source
Aerobic fuel source
glycogen and triglycerides
Energy System Interplay
all three energy systems working together to contribute to ATP resynthesis. One is predominant over the others depending on intensity and duration
Glycaemic Index
ranks food on a scale of 0 to 100 according to how much they raise blood sugar over a two-hour period, compared to pure glucose
High GI foods
white bread, lollies, white rice, broad beans
Low GI foods
multigrain bread, yoghurt, corn, apples
Glycogen sparing
allows fats to be used more readily and earlier during performances
