energy system s Flashcards
what is ATP
-only direct source of energy
-enough ATP in our muscles to sustain 2-3secs of movement
-to continue performance body must resynthesise new ATP compounds
-body breaks down other chemical compounds to release energy required to resynthesise
how long does ATP-PC system last
8-10 seconds
ATP PC system source
phospho creatine
recovery time of ATP PC system
4 mins
source of the lactate system
glucose
how much atp is used in lactate system
2
how long does lactate system last
1-3 mins
what are the fatiguing by products of the lactate acid system
pyruvate (lactic acid)
recovery time for lactate system
8-10mins
source of aerobic energy system
glucose and fats
how much atp in aerobic system
38 —> 2,2,34
how long does aerobic system last for
2hours
can go longer at lower intensity
bi products of aerobic system
water
recovery time for aerobic system
24hrs+
adaptations of energy systems
-muscles improve storage capability of PC: means performer can exercise at maximal intensity without production of by products
-body extends its capillary network higher lactate tolerance
-improved oxygen delivery+higher intensity performance can be sustained for longer
additional factors
-diabetes
-hypoglycaemia
-child lactate system
what is hypoglycaemia
-when blood glucose levels are lower than usual
-cause dizziness, shakiness and unconsciousness
how does anerobic activity place additional stress on a younger body
-cardiovascular system isn’t fully developed
-less muscle mass and PC causes difficulty to induce aerobic respiration
what is the electron transport chain
-occurs when oxygen is present
-occurs in mitochondria
-receives hydrogen ions
-32-34 atp are created
-water is the by product
