16
Q

the energy for contraction comes from the ..

A

bond or the “tail” of the phosphate molecule.

17
Q

our ATP stores are very limited therefore

A

ADP must continually be rebuilt to ATP

18
Q

nutrients assist in the ATP cycle by..

A

providing energy to rejoin the floating phosphate back to the ADP to make ATP once again

19
Q

what are the 4 factors ATP is used during the physical activity

A

-activity duration
-activity intensity
-the individuals aerobic fitness level
-the level of recovery achievable between efforts

20
Q

when the body participates in physical activity it can produce energy either

A

anaerobic -without oxygen
or aerobically - with oxygen

21

22
Q

Name the 3 energy systems

A

-phosphate energy system (ATP-PC)
-Anaerobic glycolysis system
-aerobic glycolysis system
