Energy Continuum Flashcards
1
Q
Define energy continuum
A
The relative contribution of each energy system to ATP re-synthesis and determined by the intensity and duration
2
Q
What is the fuel for the ATP - PC system?
A
Phospocreatine
3
Q
What is the fuel for the lactic system?
A
Glycogen
4
Q
What is the fuel for the aerobic system?
A
Glycogen
5
Q
Define OBLA
A
The point at which the concentration of lactic acid suddenly increases
6
Q
Why does OBLA occur?
A
The aerobic system can no longer provide energy quickly enough because the intensity of activity has increased
7
Q
What are the 3 effects of OBLA?
A
Muscle fibres become more acidic
Effects enzyme activity and inhibits breakdown of glycogen
Makes muscle contractions difficult causing fatigue
