Stretching Flashcards
Difference between ROM & Stretching?
ROM = MAINTAIN tissue length (no pull)
Stretching = Past point of resistance to INCREASE muscle length (feel pull)
Tissues that are affected by stretching?
- Tendons
- Ligaments
- Fascia
- Skin
What is ‘Hypomobility’?
Low mobility/motion
Causes of Hypomobility?
- Aging
- Effusion (swelling)
- Weak/painful muscles (eg: tendonitis)
- Nerve injury
- Skin disorder (burn)
- Broken bone
- Vascular/blood disorder
Benefits of stretching?
- Reduce risk of joint deformity
- Reduce injury risk
- Reduce post-exercise soreness
- Improve overall function
- Improve muscle performance
What happens when we stretch ‘contractile’ tissue (muscle)?
Muscle contracts (shortens) & sarcromeres lengthen
What is ‘Non-contractile’ tissues response to stretch?
Depends on what they are made of:
Collagen response = more strength (**& we need to resist force)
Elastin response = more extensibility
We want to get to the ‘PLASTIC RANGE’ so stays at new length without being strained(if goes back = ‘elastic range’)
To get plastic range we must break collagen tissue
(NOT ligament or tendon)
Which is the safest form of stretch?
Low-load/intensity, Long duration stretch, 3-6 times a week
(just past tissue resistance, 30-60 secs)
Yields most significant long-term plastic changes in soft tissue
The stiffer you are the less motion you have = stretch more often (6 times a week)
Intense stretching = stretch less (like weight lifting reps)
Stretching contraindications?
- Bony block (blocking motion)
- Recent fracture (when healing)
- Acute inflammation
- Infection
- Hematoma (swollen bruise)
- Hypermobility (too much stretch already)
- Hypomobility (if pregnant)
