Handout #4 - CV Response Isometric Exercise

Question 1

SBP = ___

Answer 1

Pressure in arteries when heart beats

Question 2

DBP =

Answer 2

Pressure in arteries during heart relaxation

Question 3

During dynamic exercise, what is the response of SBP, MAP, and DBP?

Answer 3

1. SBP Increases
   – increased CO
2. MAP increases (aids in BF)
3. DBP slightly decreases
   – decreased systemic vascular
   resistance and increase HR

Question 4

MAP =

Answer 4

Mean arterial pressure

Driving force to move blood out of muscle

DBP + 1/3 (SBP-DBP)
