02a. Energy Systems - ATP-CP system Flashcards
What releases the energy for muscular contraction?
The high energy bond between the second and third phosphate in ATP breaking apart.
The high energy bond between the second and third phosphate in ATP breaking apart results in what?
Muscle contraction
What is the rate of the ATP - CP system?
Very high
Which energy system has the highest rate?
ATP-CP
What is the intensity of the ATP-CP system?
95%MHR +
Which energy system is contributing most significantly at intensities 95% MHR+?
ATP-CP
What is the yield of the ATP-CP system?
very low (0.7mmol)
Which energy system has the lowest yield?
ATP-CP
What is the cause of fatigue for events that the ATP-CP system contributes most significantly to?
Depletion of CP
What is the duration the ATP-CP system contributes most significantly for (after sufficient rest)
7-10 seconds
What type of recovery is associated with the ATP-CP system?
Passive
Describe passive recovery
very low/limited movement eg. standing still/walking
Why is passive recovery best for the ATP-CP system?
As it replenishes CP QUICKLY/RAPIDLY
When is the ATP-CP system contributing most signicantly?
initial efforts after sufficient recovery
high intensity efforts after sufficient recovery
What is the fuel of the ATP-CP system?
Creatine phosphate (CP)
What are the by products of the ATP-CP system?
ADP and Pi (inorganic phosphates)
How much does the ATP-CP system contribute in a sprint to the line of a 5km run?
Minimal - it has a finite capacity that was exhausted at start
How long is required for fully depleted CP to be fully replenished using passive recovery?
3-5mins
Which letter is most likely to represent the ATP-CP system in a 200m sprint?
A
Anaerobic glycolysis contirbutes most significantly, ATP-CP second
Which letter is most likely to represent the ATP-CP system in an 800m run?
B
Aerobic most significant then AG, CP least
Which letter is most likely to represent the ATP-CP system in 110m hurdles?
C
