| What are the 4 aspects of exercise prescription |
|
Definition
Intensity
Duration
Frequency
Mode(s) |
|
|
Term
- Decreased risk of CVD with mild intensity walking
- Conservative limit is 40% of the HR reserve
- HRR = max HR - resting HR
- Max HR can be determined in the lab or estimated
- Estimated max HR: 220-age in years
- Formula underestimates the max HR in the elderly |

| What is the formula for heart rate reserve? |
|
Definition
|
|
Term
| Mortality related to max intensity is how many METs? |
|
Definition
|
|
Term
| High enough to increase exercise tolerance, VO2 max. Low enough to be safe. |
|
Definition
|
|
Term
| Is it difficult or easy to prescribe intensity for low risk or high risk patients? |
|
Definition
|
|
Term
| Is it easy or difficult to prescribe intensity for moderate risk pts? |
|
Definition
|
|
Term
| What is the target HR formula? |
|
Definition
| Target HR = (MHR-RHR)(%)+RHR |
|
|
Term
| The percent of HR reserve plus resting. Takes the resting HR into account. |
|
Definition
| Karvonen Method of target HR |
|
|
Term
| Examples of 50 yo prescription at 70% |
|
Definition
APMHR = 220-50 = 170
HRR = 170-70(resting) = 100
70% of 100+70 = 140 |
|
|
Term
A simple percentage is 170 x 0.70 = 119
Whats wrong with this method? |
|
Definition
Too conservative
Resting HR is not considered
Increase in HR of only 49 |
|
|
Term
| If Karvonen = 140 what does this tell us? |
|
Definition
|
|
Term
Heart rate by target heart rate
70% of age-predicted max HR
Progressing to 85%-90% |
|
Definition
|
|
Term
Target HR based on SLHR
-Exercise-induced ischemia
-Exercise-induced arrhythmias
-Exercise-induced abnormal hemodynamics
-Rate-pressure product at exercise induced angina
-Begin at low % of HRR based on S-L max
-Progress from 40-85%
-Use subjective evidence and experience to progress intensity |
|
Definition
|
|
Term
-Close supervision
-Telemetry
-Emergency equipment
-Primary goal: increase functional capacity (producing peripheral changes)
-40% of symptom-limited max
-Usually in the range of 100-120 bpm |
|
Definition
|
|
Term
| Give an example of a high risk pt |
|
Definition
Resting HR = 100
Symptom-limited max = 140
HRR = 40
40 * .4 + 100 = 116 |
|
|
Term
| 5 components of prescription by METs |
|
Definition
1. Tables for diff activities
2. Prescribing home exercise for low risk individuals
3. Add variety for low risk pts
4. To restrict activities to safe MET level for mod to high risk
5. Exercise of mod and high risk pts must be structured |
|
|
Term
| 4 components of prescription by RPE |
|
Definition
1. low risk, not mod or high risk
2. Reason: Unable to self monitor HR, use of beta blockers, heart transplant, pacemaker
3. 12 to 13 (somewhat hard) for lower limit
4. 16 (hard) for upper limit |
|
|
Term
| Slows down the heart so it can contract better |
|
Definition
|
|
Term
| Why does a heart transplant matter with RPE? |
|
Definition
| Nerve to the heart have been cut so it will not respond to exercise correctly |
|
|
Term
| 3 components under frequency and duration. |
|
Definition
1. Three sessions of aerobic activity at least 20 minutes long each week at the proper intensity
2. Person exercising to control blood glucose (same "dose" of exercise every day)
3. Sliding scale of intensity, duration and frequency (low fitness level should be short and more frequent whereas a high fitness level should be longer and less frequent) |
|
|
Term
|
Definition
Multiple short sessions
Non realistic for outpatient |
|
|
Term
|
Definition
1-2 daily sessions
not realistic for outpatient |
|
|
Term
|
Definition
3-5 sessions per week
More typical of phases II, III, and IV progression. Decent for outpatient. Minimum of 3 times a week |
|
|
Term
| How long should warm-up stretching last. This includes active ROM or light stretching and slow walking. |
|
Definition
|
|
Term
| How long should aerobic activity last? |
|
Definition
|
|
Term
| During tx session, how long should the cool down last. This includes a slow walk or an unloaded bicycle ergometer |
|
Definition
|
|
Term
| What are 7 aerobic exercise modes |
|
Definition
-Walking/jogging/running
-Cycling
-Swimming
-Skating
-Aerobics/Stepping
-Rowing
-Less aerobic activities include games with intermittent running |
|
|
Term
| Name 3 components of strengthening |
|
Definition
1. Cannot avoid resistive activity
2. Can avoid straining with heavy resistance
3. Component of exercise prescription only in low risk pts |
|
|
Term
| Name 4 types of resistance exercises |
|
Definition
1. Weight lifting
2. Isokinetic devices
3. Medicine balls
4. Movement of body weight at a mechanical disadvantage |
|
|
Term
| What 5 things would make a pt a poor candidate for strengthening? |
|
Definition
1. Unstable angine
2. Uncontrolled HTN
3. Uncontrolled arrhythmias
4. CHF
5. Functional capcity less than 6-7 METs |
|
|
Term
| 6 guidelines for stengthening |
|
Definition
1. low resistance initially (30% of one rep max)
2. Increase reps
3. Start with large ms groups
4. Progress to small ms
5. Even, rhythmic lifting and lowering
6. Avoid valsalva maneuver |
