Exploring ROM

Question 1

Flexibility

Answer 1

• the ability of a muscle or muscles to legnthen passively

Question 2

mobility

Answer 2

ability of the joint to move through its full range of motion (active)

Question 3

Flexibility determinants:** joint factors**

Answer 3

• joint structure
• bony prominences
• joint capsule
• ligament

Question 4

Flexibility determinants: **MTU structure **

Answer 4

MUSCLE
- contractile function
- passive elongation
- architecture
EPI/PERI/ENDOMYSIUM
- collagen content
- layers of skin that contribute to resisting of movement
TENDON
- morphology
- passive elongation
- stiffness
- material properties
FASCIAE

Question 5

Flexibility determinants: **neural factors **

Answer 5

• pain sensitivity (muscle guarding + spasm)
• pain threshold
• reflexes
• voluntary muscle activity

Question 6

Flexibility determinants: **external factors **

Answer 6

• temperature (cerebral palsy, cold spasticity)
• clothing/equipment
• psychosocial setting

Question 7

Flexibility determinants: other

Answer 7

• age (lose elastin in the soft tissues)
• sex (hormones)
• hormones (relaxin causes laxity which increase ROM)
• disease
• skin
• neural tissue ( signal from brain to muscle)
• physical obstructions (soft tissue approximation)

Question 8

what is a benefit of flexibility

Answer 8

• helps prevent injury to the muscles and joints

Question 9

whats a benefit of mobility

Answer 9

• help build stregnth, mobility in muscles and joints
• prevents tightness
• prevents subsequent injury

Question 10

static stretch

Answer 10

FLEXIBILITY
after workout/ following warmup

Question 11

dynamic warmup

Answer 11

MOBILITY
before workout/ faster movements

Question 12

Types of stretching

Answer 12

• static hold in position
• dynamic movement

Question 13

types of mobility

Answer 13

• active muscles actively work to shorten and lengthen to produce movement
• passive Movement is passive and produced by an external force.
• active-assisted a combination of the above

Question 14

What is VISCOELASTOCITY

Answer 14

viscous - resists flow and can change shape (permenant)
elasticity deforms when stress is applied to it but can returen to its normal shape (reversible)

temperature has an affect on tissue/muscle. warmer more ROM

Question 15

Thixotrophy

Answer 15

creep when giving flexibility exercise a key aim is to allow time for adaptation to occur
