Flashcards in 26. Exercise Prescription Deck (11):
1

When should a patient who had a recent MI begin cardiac rehab?

AFTER myocardial healing (6-8 weeks post MI)

2

What are the acceptable forms of activity to start cardiac rehab?

-Walking
-Biking
-Recreational games
-Swimming in a pool (water temp 27-30 C)
-Gardening
-Fishing

3

What are the health benefits of walking?

-Reduce risk of coronary heart disease and stroke
-Reduced high cholesterol
-Lower BP
-Reduce risk of colon and breast cancers
-Reduce body fat and help control weight
-Increase bone density --> help prevent osteoporosis and osteoarthritis)
-Reduce risk of type II diabetes
-Flexibility
-Mental well being

4

What activities should a patient avoid after having an MI?

-Static exercise w/ temporary breathold (valsalva maneuver)
-Lifting heavy weights
-Heavy, strenuous arm work

5

What are the mechanisms by which exercise increases risk of CV events in cardiac patients?

-Increased wall stress and O2 demand from increased HR and BP --> ischemia
-Increased flexing of coronary arteries --> plaque disruption and thrombosis
-Coronary artery spasm in diseased or hypoxic segments
-Ischemia-induced ventricular fibrillation from regions surrounding a previous MI scar

6

When are cardiac events more likely to occur for cardiac rehab patients?

Transitioning into and out of exercise

7

List the FITTE factors for increasing cardiorespiratory fitness.

-Frequency
-Intensity
-Time
-Type
-Enjoyment

8

What should be the frequency of exercise?

3-5 days/week

9

What should be the intensity of exercise?

-65-90% HRmax
-50-85% VO2reserve or HR reserve

10

What should be the time per session of exercise?

20-60 mins

11

What type of exercise should cardiac patients be doing? Frequency of each?

-Aerobic conditioning (3-5x/week)
