movement where the angle between the bones increase
flexion
movement at the joint where the angle of the bones decrease
abduction
where limbs are moved away from the body
adduction
where the limbs are moving towards the body
rotation
turning a limb along its axis
plantar flexion
movement at the ankle where the toes are pointed down
dorsifelxion
movement at the ankle where the toes are pointed towards the knee
circumduction
when a limb is held straight and is moved in a circular shape
haemoglobin
red pigment found in red blood cells which transports oxygen around the body
oxyhaemoglobin
formed when oxygen combines with haemoglobin
vascular shunting
process that increases blood flow to active areas during exercise by diverting blood away from inactive areas (achived by vasodilation and vasoconstriction)
diastole
the relaxation phase of the cardiac cycle
systole
the contraction phase of the cardiac cycle
EPOC (excess post-exercise oxygen consumption)
increased rate of oxygen intake following strenuous activity
during anerobic exercise energy is produced
this builds up latic acid in muscles and oxygen debt
