Isometric (static) exercise differs from isotonic (dynamic) exercise in that it causes a greater increase in

A. False   The muscle pump is more effective in dynamic than in static exercise.

B. True   In dynamic exercise, the muscle pump increases venous return and so decreases venous pressure in dependent veins.

C. False   The increase is less since inflow is obstructed by the sustained compression exerted by the contracting muscle.

D. True   There is relatively little fall in total peripheral resistance with static exercise.

E. True   The rise in arterial pressure with static exercise increases cardiac work since cardiac output has to be ejected against a higher aortic pressure
