Week 12 Flashcards
Why do therapeutic exercise?
- Recover after injury/surgery
- Prevention
- Improve general health
AROM (Active range of motion):
Strength through full ROM
AAROM (Active assisted range of motion):
Regain full ROM
PROM
only for ROM
no strength involved
Why do flexibility exercises?
- Aim to “reestablish length of a muscle”
- Muscle is strongest when it’s longest
- Tightness in muscle restricts blood flow
Goal of flexibility exercise
Increased ROM of joint
altering the extensibility of muscles
Proprioception
Knowing where your body is in space
Muscle spindle
Found in ‘muscle belly’
–> its job is to tell brain 1) speed (how fast) and 2) length (how long) of muscle
- Keeps from injury
Golgi Tendon
Found in muscle tendon
Its job is to tell how much tension is in the muscle, so it doesn’t tear
Static stretching
traditional stretch
1) Slow – move too fast
Actively causes muscle to tense up
Why? Muscle spindles are affected
2) Talk about pain
Should never feel above a 3/10 on pain scale when exercising
How long should you do static stretching for? why?
Under 65 = 30-60 seconds: allows muscle spindle to stop firing
Over 65 = 60 seconds: changes in collagen
What should you do after static stretching
- 3-5 minutes of repetitive activity (walking, active arm exercises)
NEVER static stretch BEFORE gym/recreational activities
–> Causes microtrauma to muscles, need to recover
Why after workout?
- Speeds muscle recovery
difference between static and dynamic stretching
static
- Hold elongated position
- Isolate muscle group
- 30-60 seconds
- Example: Hamstring stretch
dynamic
- Progress length/speed muscle
- Usually UE/LE
- No hold = no damage
- Example: leg swings
What muscles will get tight if sedentary/geriatrics population?
- Hip flexors
- Hamstrings
- Hips
- Core (weakness)
Work major muscle groups 2x per week
Finish with gentle stretching
What kind of CT changes are there in geriatrics?
CT stiffens – decrease in water content, increase in collagen bundling, increase in elastic crosslinks
CT changes: less H2O in the collagen
