energy systems general (inc AO2) Flashcards
what are the 3 energy systems
ATP-PC system
lactate anaerobic system
aerobic system
which energy system is used is dependent on 3 things…
intensity
duration
presence of oxygen
gymnastics vault
atp-pc (5 sec)
100m butterfly swim
lactate anaerobic (49 sec)
throwing a cricket ball
atp-pc (2 sec)
a sqaush rally
lactate anaerobic (18 sec)
a steady 5 mile run
aerobic (45-50mins)
running a marathon
aerobic (2hours+)
what is the energy continuum
which energy system is used and the relative contributions the energy systems make to the production of energy
eg of atppc in netball
the first center pass when the wa sprints out to receive the ball
eg of atppc in football
penalty kick
eg of atppc in rubgy
conversion kick
eg of LA in netball
ga and gs running around the D to get in a postition to shoot
eg of aerobic for netball
center running up and down the court during a quarter
eg of aerobic for football
midfielder running up and down the pitch
football LA eg
turnover and sprint to attack
what increases as we exercise
demand for energy rises rapidly
what does the energy continuum describe
which energy system is being used for different types of physcial activity, it refers to the type of respiration used by physical activities- depending on the intensity or duration.
energy systems do not work….
independently of each other but all contribute during all types of physical activity there there will be one predominant energy provider
a marathon runner gains the first few minutes of energy from the …. and ….. until a steady state is reached then the ….. is mainly used
atp-pc and lactate anaerobic
aerobic
what are the thresholds (not%)
the point where the energy system (atp-pc) is exhausted and the anaerobic glycolysis system takes over (10s), then the anaerobic glycolysis threshold is exhaused (70s) and the aerobic system takes over
