Helpful Guide:
System—choose one as the predominate system. If you don’t know the sport look it up. Most sports will use more than one system but based on exercise intensity—choose one.
Fuel—What fuel is used for the activity? A very short sprint will use Creatine or you could say creatine phosphate (see example). A glycolytic energy system activity will only use Carbohydrates while aerobic exercise will use carbohydrates and fat for fuel (see example).
Intensity—Exercise intensity determines the energy system that’s used. All-out = Creatine Phosphate; Moderate-High Intensity = glycolytic system; Moderate to Low Intensity = aerobic.
Note: when you determine the energy system of a sport look at the actual time it takes for the event, play, etc… example = baseball outfielders stand around a lot between plays but go all-out when chasing a ball, running the bases…so this is an ATP-PC system activity NOT aerobic.
