Which energy system has the second highest rate?
Anaerobic glycolysis system
Which energy system is contributing most significantly at intensities 85- 95% MHR?
Anaerobic glycolysis system
Which energy system has the second lowest yield?
Anaerobic glycolysis system
Which energy system has the lowest rate?
Aerobic system
Which energy system is contributing most significantly at intensities 60- 85% MHR?
Aerobic system
Which energy system has the highest yield?
Aerobic system
What is pyruvic acid?
a by product of glycolysis
What does the accumulation of lactate acid result in?
H+ions
What causes H+ions?
The accumulation of lactic acid
How do H+ions cause fatigue?
increased acidity therefore decreased ability to use glycogen inhibiting muscle contraction
What causes increased acidity therefore decreased ability to use glycogen inhibiting muscle contraction?
H+ions
What are the three metabolic by products?
ADP, Pi, H+ions
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
