26. Exercise Prescription Flashcards
When should a patient who had a recent MI begin cardiac rehab?
AFTER myocardial healing (6-8 weeks post MI)
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
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
What activities should a patient avoid after having an MI?
- Static exercise w/ temporary breathold (valsalva maneuver)
- Lifting heavy weights
- Heavy, strenuous arm work
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
When are cardiac events more likely to occur for cardiac rehab patients?
Transitioning into and out of exercise
List the FITTE factors for increasing cardiorespiratory fitness.
- Frequency
- Intensity
- Time
- Type
- Enjoyment
What should be the frequency of exercise?
3-5 days/week
What should be the intensity of exercise?
- 65-90% HRmax
- 50-85% VO2reserve or HR reserve
What should be the time per session of exercise?
20-60 mins
What type of exercise should cardiac patients be doing? Frequency of each?
- Aerobic conditioning (3-5x/week)
- Resistive exercise (2x/week)
- Flexibility (near daily)
