Energy systems - SPFC

Carbohydrates

34 - 38 ATP

Protein

15 ATP

Fats

130 ATP but takes longer to breakdown and need carbohydrates to function

Anaerobic Alactic

last for 1-10 seconds, good for fast powerful movements, uses ATP and creatine phosphate

Anaerobic Lactic

Fast powerful movements at high intensity for 10 seconds to 2 mins, incomplete breakdown of CHO with byproduct of lactic acid

Aerobic system

Working at medium to low intensity for longer derations, complete breakdown of CHO and fats, happens in mitochondria

Steady state

occurs in the aerobic system and used in long periods of activity as body maintains movement.

Sliding filament theory 

when proteins in muscle cells slide over each other to create a contraction using ATP. 

EPOC - excess post exercise oxygen consumption

Resynthesis of lactic acid into glycogen restores oxygen into blood. where benefits of workout happen. Elevates core temp heart rate and ventilation.

Do I burn calories after I workout?

Yes after exercise you burn calories to assist in recovery - result of ECOP

Chronic effects of Aerobic system

increased the number and size of mitochondria allowing for energy and increasing the ability to do work. increases stroke volume.

Chronic effects of Anaerobic Lactic

increased tolerance to lactic acid, increased anaerobic enzymes that breakdown glucose, Increased fiber recruitment 

Chronic effects of Anaerobic Alactic system

increased stores of ATP and CP and enzymes to break them down, increased speed of fiber recruitment
