Q

submax exercise testing

A
  • patient achieves predetermined exertional level, then stop
  • ramped, progressive protocol
  • no expired gas analysis performed
  • VO2 max or VO2 peak can be extrapolated from the test

Q

Bruce Protocol: What should be measured at each stage

A

HR
RPE
BP if possible

17
Q

6MWT:

physiological measurements that need to be made during assessment of exercise capacity

A
  1. BP (pre and post)
  2. HR (pre and post)
  3. RR (pre and post)
  4. RPE (during and post)
  5. Rating of breathlessness (during and post)
  6. arterial O2 saturation
18
Q

MCSD for 6MWT must be between

A

54 and 80 m

19
Q

Examples of Submax exercise tests

A
  1. single stage submax treadmill walking test
  2. astrand and rhyming cycle ergometer test
  3. 2MWT
  4. mod shuttle walking test
  5. bag and carry test
  6. physical function ICU test
20
Q

Methods of assessing strength

A
  • MMT
  • 1 rep max
  • hand held dynamometer
  • isokinetic machines
21
Q

1 rep max

A
  • max weight person can lift 1 time through FULL ROM with GOOD FORM
  • make sure to ask RPE and use to assess subjective effort
  • increase weight for next trial by 4-6 lbs
  • 30 sec between trials and alternate UE and LE
  • over when patient can’t complete ROM
22
Q

predicting 1 rep max

A

10 reps resulting in fatigue / .75

23
Q

power

A

amount of work produced per unit of time

P=force x velocity

24
Q

Power tests

A
  • peak cycling
  • stair climb
  • 30 sec repeated STS
  • TUG
  • TUDS
  • 5xSTS
  • stair climbing power test
25
Q

stair climbing power test

A

determine time required to climb 10 stairs as quickly and as safely as possible

26
Q

T/F: Strength and high-velocity resistance training in healthy, well-functioning older adults significantly and similarly improved muscle power and muscle strength.

27
Q

T/F: Peak muscle power was inferior to muscle strength in determining functional status

A

False

independently predicts functional dependency, even after accounting for neuropsychological and health status indicators

28
Q

What amount of aerobic, resistance, or combined training can significantly improve physical function?

A

3x/week x 8-12 weeks
