Answer to Question #131107 in Human Anatomy and Physiology for suzy chami

Question

Immediately after exercise was the amplitude of the pulse smaller or larger than during resting period?

What was the finger pulse amplitude before and after exercise? please explain the physiology . consider how this relates to blood vessels and movement around the body

heart rate per minute mean pulse amplitude

rest 72 102

10 sec post

exercise 123 53

Answer 1

Immediately after exercise the amplitude of the pulse was larger than during resting period.

The finger pulse amplitude before exercise was 30 and after exercise was 70.

The amplitude of the pulse depends primarily on the magnitude of the stroke volume and the volumetric velocity of blood flow in diastole, which is also affected by the elasticity of the vessels that absorb shocks.

The walls of the arteries, which are stretched during systole, accumulate energy, and 

 during diastole they fall and give off the accumulated energy.
