Chapter 1: Safe Dance Practise: Flexibility

Question 1

What does increasing flexibility do?

Answer 1

increasing musclular elasticity so that the range of motion (ROM) of joints will increase.

maintain muscular balance in the body

help alignment

help safe working methods

avoidance of injury

Question 2

What must flexibility not involve? Why?

Answer 2

stretching ligaments that provide the joints with stability because elongation of the ligaments increases the posibilty of injury

Question 3

What limits flexibility?

Answer 3

ligaments

tendons

bony restriction

individual differnce in fascial sheath surrounding muscles affects the ROM

Question 4

What is the function of cartilaginous joints?

Answer 4

allow little movement

give great strength

cartillage contains water cushioning pressure bwtween bones

crucial for absorbing shock

Question 5

What is the function of fibrous joints?

Answer 5

allow little or no movement

bones closely connected by seams of tough fibrous connective tissue

Question 6

what is the function of synovial joints?

Answer 6

allow ROM

Question 7

What are the 6 movements performed by joints?

Answer 7

Flexion

Extension

Abduction

Adduction

Rotation

Circumduction

Question 8

Shoulder

what type of joint is it and what is its movement range?

Answer 8

ball and socket

adduction, abduction, flexion, rotation

Question 9

Hip

what type of joint is it and what is its movement range?

Answer 9

synovial, triaxial

extension and circumduction

Question 10

Wrist

what type of joint is it and what is its movement range?

Answer 10

biaxial, synovial

adduction, abduction, flexion, extension

Question 11

Foot

what type of joint is it and what is its movement range?

Answer 11

non-axial

linear

Question 12

How is flexibility improved? Why?

Answer 12

stretching

lengthens the muscle along the direction of the fibres

Question 13

What are the benefits to regular and safe stretching in term of preventative practise?

Answer 13

1. improves alignment
2. releases muscular tension
3. increases muscle temperature (making them more flexible)
4. makes joints and muscles more elastic
5. helps to prevent and aids recovery from injury
6. increases concentration
7. releases toxins from the muscles after heavy physical exertion to help recovery from exercise

Question 14

What methods of stretching can overcome the blocking effect?

Answer 14

ballistic

static

dynamic

reciprocal inhibition
