ATP Resynthesis During Exercise Flashcards
What is energy production during exercise determined by?
Duration and intensity of exercise
What does the energy continuum show?
- All systems are used at the same time, though one predominantly used at a time.
When does the ATP-PC system provide energy?
(Use a sporting example)
Provides energy during maximum intensity exercise for a short duration, around 10 seconds.
e.g. 100m sprint
When does the glycolytic system supply energy?
(Use a sporting example)
Provides energy during high intensity exercise for an intermediate period of time, around 2-3 minutes.
e.g. bouts of anaerobic exercise in rugby
When does the aerobic system supply energy?
(Use a sporting example)
Provides energy during low intensity exercise which lasts for an extended period of time
e.g. triathletes
Why will the aerobic system always resynthesise?
We are always inspiring oxygen
What is the effect of aerobic and anaerobic fitness?
They dictate the threshold of each energy systems
What is the effect of high anaerobic fitness?
The athlete can exercise at a higher intensity for longer due to increased stores of phosphocreatine and improved ability to handle lactic acid
What is the effect of good aerobic fitness?
The athlete can support a greater intensity of exercise before relying on anaerobic glycolysis for energy
What is the recovery period for the ATP-PC system?
(Try and use a sporting example)
Recovers after 3 minutes.
e.g. breaks in play or time outs
What is the recovery period for the glycolytic system?
(Try and use a sporting example)
Recovers after 2-10 minutes depending on usage.
e.g. half time or end of quarter
What is the recovery period for the aerobic system?
(Try and use a sporting example)
Recovers after up to 24 hours, depending on duration and intensity.
e.g. breaks between matches
