Q

why use isometric exercise

A
  1. Minimize muscle atrophy when joint movement is not possible
  2. Activate muscles to begin to re-establish neuromuscular control
    * Protect healing tissues
  3. Develop postural and joint stability
  4. Improve muscular strength when dynamic RT could compromise joint integrity or cause pain
  5. Develop static muscular strength at particular points of ROM (20° max) * Specific task related needs

16
Q

how does the resistance must be apply

A
  • Resistance must be progressively increased to overload the muscle *
    Apply and release the tension gradually
17
Q

concentric vs eccentric contraction

A

conc: shortening of a muscle with contraction, accelerate body segment
ecc: lengthening of a muscle while controlling against force, decelerate body segment, shock absorber

18
Q

what is isotonic activity

A
  • Involves change in muscle length
  • Constant resistance throughout
    the exercises
  • Speed of movement will change
19
Q

what is isokinetic activity

A

Involves change in muscle length
* Velocity is controlled and maintained at a specific speed of movement
* “Having the same motion”
* Amount of resistance provided to the muscle varies as the muscle goes through a range
* Form of dynamic exercise in which velocity of a muscle shortening or
lengthening and the angular limb is predetermined

20
Q

which one between isokinetic and isotonic that Movement that occurs at an equal or constant velocity (speed)

A

isokinetic

21
Q

where does isokinetic exercise is used

A

rehab setting

22
Q

what are the characteristic of isokinetic exercise

A

train reciprocal muscle
compressive force on join is less with faster velocties than at slow velocities
patient can still perform exercise even if fatigued
patient is able to eliminate painful ac
speed avaible in sport is more than in machine

23
Q

which type of exercise can train reciprocal muscles

A

isokinetic

24
Q

type of resistance exercise depend on

A
  • Extent of impairments
  • Stage of tissue healing
  • Condition of joints and their tolerance to compression and movement
  • General physical and cognitive abilities of the patient
  • Patient’s goals
25
Q

which type of positioning for resistance exercise is safer during rehab program

A

WB (CKCE)

26
Q

which type of positionning of resistance exercise can better isolate muscle

A

NWB (OKCE)

27
Q

which type of positionning of resistance exercise more shear force at joint

A

NWB

28
Q

which one between closed kinetic and open kinetic resistance exercise is hight velocity movement

A

open kinetic

29
Q

when do we use OKC

A
  • When weight bearing is
  • Soft tissue pain and swelling or restricted ROM of any segment in the chain, may require OKC exercises at adjacent joints
  • First to develop isolated control and strength of weak musculature
  • Sport/activity requires it
30
Q

when do we use closed kinetic chain

A
  • Promote dynamic stabilization and co activation
  • Provides greater proprioceptive and kinesthetic feedback
  • Provides more joint stability * Sport/activity requires it
31
Q

parameter for resistance training in early rehab

A

6-15 reps for 2 sets

32
Q

when do we know that our athlete is ready to increase weight and decrease reps

A

Continue with constant weight until able to perform 3sets of 20-25 repetitions

33
Q

what is the common guideline in resistance exercise for increasing weight

A

increase weight 5-10% when all prescribed repetitions and sets can be completed easily without significant fatigue

34
Q

in early rehab the neumber of set and reps and speed will depend on

A

demand of sport and ADL

35
Q

training goal of strength power hypertrophy muscular endurance

A

Strength <6reps 2-6 sets
Power Single effort Multiple effort
1-2 reps 3-5 sets
3-5 reps 3-5 sets
Hypertrophy
6-12 reps
3-6 sets
Muscular endurance
>12 reps
2-3 sets

36
Q

is good to do our resistance training on a unstable surface if we want to gain strenght

A

no

37
Q

how munch does contribution of stabilizing muscle increase when the handle is unstable during pushing motion in squat

A

40 %

38
Q

what is the affected of working the stabilizing muscle in the force velocity and power

A

30 % drop

39
Q

what is the progression of strength training

A

Change 1 parameter at a time (frequency, intensity, speed)
Begin with isometrics if required (I.e. high pain level, ROM deficiencies, post surgical, activation of muscles)
Begin concentric/eccentric resistance training ASAP
1. Slow and controlledàincreasing speed
Begin plyometric exercises (jumping, running, cutting etc.) once patient has met appropriate requirements
