Q

What is optimal blood pressure

A

17
Q

What is normal blood pressure

A

130/85

18
Q

What blood pressure indicates stage 1 hypertension

A

140-159/90-99

19
Q

What happens to SBP during exercise

A

It increases linearly with exertion levels

20
Q

What happens to DPB during exercise

A

it can decrease due to vasodilation

21
Q

What happens to DPB during exercise to individuals suffering from hypertension

A

It increases

22
Q

What can cause a rapid increase in blood pressure

A

Valsalva effect

23
Q

What are the long term effects of exercise on BP

A

Endurance and rhythmic training helps reduce BP over time

Weight training alone does not reduce BP

24
Q

How does endurance training effect the Cardiovascular system

A 
Increased stroke volume 
stronger heart 
lower resting heart rate 
increased blood supply to tissue 
Increased oxygen carrying potential
