The period at the beginning of exercise when O2 demand is greater than O2 supply is known as:
EPOC
Oxygen deficit
Oxygen debt
Steady State

During exercise more blood is directed to the working muscles and this is achieved via:
Vasodilation of capillaries supplying muscle
Vasoconstriction of capillaries supplying muscle
Vasodilation of capillaries supplying the heart
Vasoconstriction of capillaries supplying the heart

Blood volume decreases during exercise as:
There is an increase in O2 being delivered to working muscle
A consequence of sweating, therefore a decrease in plasma
Lactate begins to accumulate faster than removal rate
There is an oxygen deficit
