Aspects of energy systems
Carbohydrates – stored in muscle and liver as glycogen, and
Glucose in blood
Carbohydrates – stored in muscle and liver as glycogen,
Fats and occasionally protein
Efficiency of ATP Production
Very quick ATP production
Quick ATP production
but fatigues drastically as
lactic acid levels rise
Slower ATP production but
endless supply
10-15 seconds
High intensity
(95-100% max effort)
30sec – 3min
Relatively high intensity
(70-95% max effort)
Endless supply
Low/moderate level intensity
(less than 70% max effort)
Limited supply of:
ATP (90g lasts 1-2sec)
And
PC (120 lasts 8-10sec)
Accumulation of
Lactic Acid
Depletion of glycogen levels
and fat stores
Process and Rate of Recovery
50% recovery in first 30sec
Full recovery in 2mins
Up to 48hours depending
on level of depletion
