Lactic Acid Flashcards
1
Q
Source of fuel
A
Carbohydrates - stored in muscle and liver as glycogen; glucose in the blood
2
Q
Efficiency of ATP production
A
Quick ATP production, but fatigues drastically as lactic acid level rise and acidosis occurs
3
Q
Duration and intensity
A
30sec - 3mins of relatively high intensity (70%-95%)
4
Q
Cause of fatigue
A
Accumulation of lactic acid, increase in hydrogen ions and acidosis
5
Q
By-products
A
Lactic acid
6
Q
Recovery process
A
Activity intensity decreases or ceases. Increased breathing rate as lactic acid is broken down in the presence of O2
7
Q
Recovery rate
A
30mins to 2hrs
8
Q
Sporting examples
A
400m, 800m run. 100m, 200m freestyle swim
