Assessment Flashcards
2 good reason for testing
- Provides baseline values prior fitness program
2. A key determinant of maintaining independent living (BADL & IADL)
Direct (2 adv + 3 dis) vs Indirect method (5 adv + 1 dis)
Direct:
adv
- More accurate (3 to 5% error)
- Better estimation of desired intensity)
dis
- Required expensive and sophisticated equipment
- Higher risk for adverse events (increase stress)
- Physician supervision can be required
Indirect: adv - Easier to make measurement - Require less sophisticated equipment - Lower risks to participant - Appropriate for OA with known cardiac risk factors - Commonly used with OA dis -Less accurate (10 to 20% error)
Treadmill (5)
- Expensive
- Not portable
- Difficult taking BP
- Not appropriate for OA with balance, gait and weight problems
- Functionally relevant activity
Leg cycle ergometer (5)
- Preferred testing for people with balance, gait and weight problems
- Easier to take BP
- More portable
- Not functional exercise
- Can develop localized muscle fatigue
Recumbent Stepper (Nustep) (5)
- Preferred testing for people with balance, gait, weight and impaired motor coordination.
- Not functional exercise
- Expensive + not portable
- Difficult taking BP
- Quite recent: only 1 protocol
Arm cycle ergometer (6)
- Ideal for OA with ambulation difficulty
- Can be portable
- Relatively inexpensive
- Localized muscle fatigue ine smaller arm muscle
- Lack of functional exercise
- Difficult taking BP
What can limit the type of CRF testing for OA ?
How lower is the vo2max with leg cycle vs treadmill ?
The use of equipment rather than their aerobic fitness
10%
Why modified balke-ware treadmill test most recommended by ACSM for OA? (2)
- Use slow and constant speed (2 m/h or 3.2 km/h) and small increase in grade ( 1% per minute)
- Appropriated for OA with good ambulation (healthy), cardiac problem or chronic disease.
How can we adjust the balke-ware test for OA who are in better shape ?
- Increase speed to 2,5 or 3 m/h 4 or 4.8 km/h
- Increase grade to 2% per min
Reason stop test (9)
- Angina like-symptoms
- BP drops below 20mmHG from rest
- No increase in BP with increase in exerc intensity
- No increase in HR rate with increase in exerc intensity
- Excessive increase in SBP more 260 and DBP more 115
- Subject request to stop
- Participant show physical or verbal signs of severe fatigue
- Failure of equipment testing
- Arrythmias
What is the typical walking speed for OA and YA ?
OA = 4,5 to 4,8 km/h YA = 5,3 to 5,4 mk/h
Formula to calculate O2 consumption
0,1 x speed + 1,8 x speed x grade +3,5
where speed = m/h & grade decimal fraction (8% = 0,08)
Formula for predicted max HR for balke-ware protocole
(207 - 0,7 x age) x 0,75
Protocol 1RM briefly and steps
Avoid ? (2)
- Objectif find the max weight a person can lift once
- Use spotter
- last successful attempt = 1RM
- Only 3 to 5 cycles of adding weight
steps 1: warm up with light weights about half to predicted max
step 2: 3 to 5 reps of higher weight (60 to 80% predicted max)
step 3: small amounts of add weight 2,5-5 pds
avoid multiple reps and decrease injury
Balance is defined as ?
The ability to control the body COM relative to the BOS, whether the base is stationary or moving.
