Lab 2: Exercise physiology

Question 1

How do you calculate HR max?

Answer 1

220-age

Question 2

Explain the Modified Bruce protocol

Answer 2

Every 3 minutes for 9 stages increase the either the grade of the treadmil or the speed

Take the:
* Systolic BP
* Diastolic Pressure
* MAP
* HR
* RR
* RPE
* Pulse Ox

The point of this is to assess cardiovascular endurance

Question 3

What is the MAP used for?

Answer 3

Its the average BP in the arteries throughout the cardiac cycle
* Used to see if organs are getting proper profusion

Question 4

Which one of these does not icnrease lineraly w/ EX?
* Systolic BP
* Diastolic BP
* HR
* RR
* RPE

Answer 4

Diastolic BP

Question 5

NOTE: If pulse ox drops w/ work that indicates a problem somewhere

Question 6

HR maintains after reaching steady state w/ astrand bike

Question 7

when doing astrand bike goal is to get them to 70% of HR max and stabilize there

Goal is in that warm up in the clinic you can start them out on a bike to warm up and the goal of that would be to get them into that steady state before they start doing other exercises

Question 8

Step Test
* How do you measure it?
* How is the test run

Answer 8

Mid way point between the patella and iliac crest and mark on wall

Count the # of steps completed in 2 minutes, raising each knee to a point midway between the patella and iliac crest (line you marked)

Score is the # of times the right knee reaches the target

Using a chair, table, or wall to aid in balance is allowed

Higher step counts are associated w/ a higher level of functional fitness

Question 9

What is the systolic BP response to dynamic exercise?

Answer 9

Increases much more thandiastolic
