- Lactic Acid System (anaerobic glycolysis)
- GLYCOGEN
- GLUCOSE
- PYRUVIC ACID
- LACTIC ACID
- FATIGUE
- an increase in LA = a decrease in muscle/blood PH therefore inhibits muscle contraction
- lactate dehydrogenase (LDH)
- LACTIC ACID
- FATIGUE
- an increase in LA = a decrease in muscle/blood PH therefore inhibits muscle contraction
- LACTIC ACID
- LACTIC ACID
- phosphofructokinase (PFK)
- PYRUVIC ACID
- lactate dehydrogenase (LDH)
- lactate dehydrogenase (LDH)
- PYRUVIC ACID
- PYRUVIC ACID
- glycogen phosphrylase (GPP)
- GLUCOSE
- phosphofructokinase (PFK)
- phosphofructokinase (PFK)
- 2 ATP
- GLUCOSE
- GLUCOSE
- ADVS: fast acting, lasts longer that ATP-PC, more ATP produced, no O2, Large glycogen store in muscles
- DISADVS: Lactic acid produced = poison = lowers Ph = denatures enzymes = effects processes = lower skill level = FATIGUE
- EFFECTS OF TRAINING: increased tolerance to LA, increased stores of glycogen, delayed OBLA.
- use anaerobic system, overload the LA energy system
- can work at a higher intensity for a longer duration.
- GLYCOGEN
