Anaerobic Power Flashcards
What is Anaerobic Power?
The maximal power (work per unit of time) developed during all-out, short term physical effort.
The maximal amount of energy the can be generated by the anaerobic energy systems per unit of time.
Where is the energy coming from?
APT hydrolysis-
The phosphate bonds are cleaved, a reaction catalysed by the enzyme adenosine triphosphate
What does ATP stand for?
Adenosine Triphosphate
What does ADP stand for?
Adenosine Diphosphate
Anaerobic resynthesis of ATP- Creatine kinase reaction equation:
ADP + PCr + H <——> ATP + Cr
Where are the intercellular creatine kinase locations?
- Free in the sarcoplasm
- Near the mitochondrial membranes
- Near sites of cross-bridge formation
What is the Phosphagen system? (ATP-PCr)
An anaerobic energy system in which the production of ATP manufacture is coupled with the exergonic breakdown of PCr stored in muscles.
How much ATP is produced in Anaerobic glycogenolysis?
3 ATP
What is Glycogen?
- Already mobilised storage form of glucose
- Breakdown of glycogen by glycogen phosphorylase.
What is the Margaria Power Test?
Running up the stairs test:
- Step 3 6 9
- Measures 2 meters of vertical displacement
What 3 systems contribute to anaerobic power?
- Phosphagen system
- Creatine kinase reaction
- Anaerobic glycogenolysis
What are the anaerobic power tests?
- Maximal Vertical Jump test with and without arms
- Margaria Stair-gate Test
