Glycolytic (lactic acid) system Flashcards
What exercise is the lactic acid system best suited to
Anaerobic
When does the glycolytic system kick in
After 10 seconds of exercise when ATP-PC stores are exhausted
What is the process of the glycolytic system
Glycogen - GPP - Glucose - PFK (2 ATP) - Pyruvic acid - (insufficient O2) LDH - Lactic acid
Where does the lactic acid process take place
Sarcoplasm
What is the name given to the breakdown of glucose
Anaerobic glycolysis
How long does the lactic acid system last for, and when does it reach peak efficiency
Lasts for 3 mins, peak at 1 min
What does OBLA stand for
Onset of blood lactate accumulation
What does the glycolytic system result in
Lactic acid and OBLA causes fatigue
How can OBLA and lactic acid be combatted
Anaerobic training increases tolerance
What events is the lactic acid system most useful for
200-800m running, 100m swimming
What are some advantages of the lactic acid system
Energy quickly provided, no O2 delay, more ATP provided than ATP-PC
What are some disadvantages of the lactic acid system
Inhibits muscular contraction, causes fatigue, low ATP yield with long recovery
