Stretching Flashcards
Why stretch?
To increase flexibility & mobility
what is ‘Hypomobility?
A decrease in movement
Caused by:-
- Injury
- Sedentary lifestyle
- Prolonged immobilization
- Posture & muscle imbalances
- Neuromuscular disorders
What is the effect of immobilization/decreased motion?
Weaker cross links
Disorganized fiber orientation
Less lubrication at joints
what causes ‘Atrophy’?
Decrease in ‘contractile proteins’
Decrease in myofibrils
Decrease in blood supply
Which tissues have most ‘Tensile Force’ (most to least)?
Most force = Tendon (connects muscle to bone)
Mid force = Ligament
Least force = Skin
What is the difference between PROM & Stretching?
PROM is MAINTAINING movement
- Joint health & integrity
Stretching is INCREASING movement
- Helps prevent injury
What are ‘Muscle Spindles’?
Sensory organs in muscle that respond to stretch & velocity changes to prevent overstretch & injury
What are ‘Golgi Tendon Organs’?
Sensory organs near ‘musculotendinous junction’ that respond to tension to prevent overstretch & injury
What is ‘Static Stretching’?
Stretch is held for as long as possible
- to lengthen muscle
20-30 secs is optimal
4 reps
What is ‘Ballistic Stretching’?
Repetitive bouncing or jerking stretches
- To increase blood flow & temperature
“Load Stress Strain Curve”
Describe the 2 different ranges?
ELASTIC RANGE:-
Tissue returns to pre-load state
PLASTIC RANGE:-
Permanent change in length due to failure of bonds (damage)
CREEP:-
The ability to lengthen
