|
Biogeneric conversion |
Breaking down the macronutrients into useable energy |
|
|
Carbohydrate |
Mos abundant source of nutrients as an organic substance |
|
|
Glycogen |
Stored in the liver |
|
|
Metabolism |
Macronutrients broken down in the body for energy |
|
|
ATP |
Common energy molecule for all living things Adenosine triphosphate 3 phosphates and adenosine |
|
|
Energy |
Chemical in humans |
|
|
Creatine Kinase |
ATP-PC -system is speeded up. -10 SECOND SPRINTS -Stored in the muscle |
|
|
Aerobic system |
Uses oxygen -10k which is longer -occurs in mitochondria -complete breakdown of glucose |
|
|
anaerobic system |
No oxygen getting to the muscle -uses carbs available in muscle fibres |
|
|
ATP-PC (anaerobic alactic) |
-No lactic acid produced -VERY SHORT SPRINTS |
|
|
Anaerobic glycolysis (anaerobic lactic) |
Past 100 M sprints, 400M and involved lactic acid Incomplete breakdown of CHO Pyruvic acid converted into lactic acid |
|
|
Lactic acid |
Waste produced of anaerobic glycolysis due to the incomplete breakdown of CHO/ glucose pyretic acid, converted to lactic acid with no oxygen |
|
|
Cellular respiration |
Takes place in the mitochondria Can use all three macronutrients as fuel from carbs to fats to protein -endurance activity
|
|
|
Aerobic glycolysis |
FIRST in CR Oxygen presence, pyretic acid is converted into acetyl CoA (Enters Kerb's cycle) NO oxy builds lactic acid 2 mol atp
|
|
|
Krebs Cycle |
2nd stage in CR 8 reactions 2 ATP produced |
|
|
Electron transport chain |
3rd and final stage of CR Large amount of ATP produced , 32 mol ATP |
|
|
Cori Cycle |
Process when lactic acid is converted back into pyruvate in the liver |
|
|
Fatty acids |
Stored as triglycerides -converted into energy |
|
|
Beta Oxidation |
When fatty acids are converted into acetyl-CoA |
|
|
Amino acids |
Protein building blocks |
|
|
Myoglobin |
Oxygen storage that delivers to the muscle |
|
|
Tonic muscles |
Core, don't get tired, maintain posture High 1% type 1 |
|
|
Phasic muscles |
gets tired High % Type IIA ans IIB Appendicular muscles |
|
|
Blood lactate |
Onset of blood lactic accumulation PH decreases as lactic acid increases in the blood |
|
|
Anaerobic threshold |
Blood lactate levels interfere with performance |
