Exercise prescription

Question 1

Type

Answer 1

Cardiorespiratory endurance activities

dynamic arm exercises

Resistive exercises

Question 2

dynamic arm exercises vs. leg

Answer 2

Higher HR and SBP and DBP

lower SV and VO2 max

b/c of smaller muscle mass!

Question 3

resistive exercises

Answer 3

mod intensities (60-80% 1 rep or 10 rep max)

be careful for avoiding Valsava (BP will dramatically increase and SV and heart output will decrease)

Question 4

Intensity

Answer 4

w/in range of 40-85% of functional capacity depending on initial level of fitness

% max HR

Question 5

beta blocking affects on HR

Answer 5

HR and BP can’t rise normally in response to exercise

Question 6

pacemaker affect on HR

Answer 6

affects HR ability to rise in response to exercise if FIXED

Question 7

Time

Answer 7

10-60 min

higher intensity, shorter duration

average 20-30 min

may need to complete very short, frequent exercises throughout day

Question 8

frequency

Answer 8

lower intensity, higher frequency

Question 9

when should you progress an exercise?

Answer 9

HR is lower than target HR

RPE is lower for an exercise

symptoms of ischemia so not appear at an intensity

Question 10

what is progressed first?

Answer 10

duration, then intensity

Question 11

When should you consider reduction in exercise?

Answer 11

acute illness: fever, flu
acute injury, orthopedic complications
progression of cardiac disease: edema, weight gain, unstable angina
Overindulgence (food, caffeine, alcohol)
Environmental stress: extremes of heat and cold, humidity, air pollitino

Question 12

Adverse responses leasing to exercise termination

Answer 12

DBP equal to or greater than 110mmHg
decrease in SBP > 10mmHg during exercise
Significant ventricular or atrial dysrhythmias
2nd or 3rd degree heart block
signs and symptoms of exercise intolerance (angina, marked dyspnea and ECG changes suggesting ischemia)
