Q

define: static active flexibility

A

using the agonist muscle, without any other assistance

Q

how does the type of joint affect flexibility?

A

the joint type determines the number of planes that a joint can move in

and therefore the range of motion/flexibility

e.g. ball and socket joints (3 planes) have a greater range of motion than hinge joints (1 plane)

Q

how does length of surrounding tissue affect flexibility?

A

the longer the length and elasticity of the surrounding tissue,

such as ligaments, tendons and muscles,

the greater the range of flexibility

Q

how does gender affect flexibility?

A

females tend to have greater flexibility than males

due to higher levels of the hormones oestrogen and relaxin.

these hormones increase connective tissue elasticity

Q

how does age affect flexibility?

A

flexibility is greatest in childhood and declines with age

as elasticity in the surrounding connective tissue is lost

Q

what are advantages of the sit and reach test?

A
  • equipment is relatively cheap

Q

what are disadvantages of the sit and reach test?

A
  • limited use: only measures static flexibility in the lower back and hip joints
  • other joints cannot be measured
17
Q

what are advantages of goniometry?

A
  • can be used to measure flexibility of any joint, in any plane of movement
  • as long as the correct technique is used, accurate and valid measurements are given
18
Q

what are disadvantages of goniometry?

A
  • it can be difficult to locate the joint centre, where the pivot of the goniometer must be placed
  • test is invalid and unreliable if correct procedure is not followed
19
Q

what are the two types of stretching?

A

static and dynamic

20
Q

what is static stretching?

A

stretching that doesnt involve moevement

21
Q

how long are static stretches generally held for?

A

10-30 seconds

22
Q

what are the two types of static stretch?

A

active and passive

23
Q

what is active stretching?

A
  • static stretching
  • unassisted voluntary static contraction of an agonist muscle to stretch connective tissue in antagonist, just past its point of resistance.
  • the position is held using the stretch of the agonist muscle for 10 seconds
24
Q

what is passive stretching?

A
  • static stretching
  • taking a joint just past its point of resistance with assistance
  • help up to 30 seconds
25
Q

what is isometric stretching?

A
  • static stretching
  • the stretched muscle undergoes isometric contraction for 10 seconds
  • resistance is needed to ensure no movement takes place
26
Q

what is PNF stretching?

A
  • static stretching
  • assisted flexibility training using passive and isometric techniques to inhibit the stretch and allow a greater range of motion
27
Q

what is static stretching?

A

stretching that doesnt involve moevement

28
Q

what is dynamic stretching?

A

stretching that involves movement

29
Q

describe dynamic stretching using an example.

A
  • using a controlled movement, bounce or swinging motion to take a joint to the limit of its range of motion

eg walking lunges

30
Q

describe ballistic stretching using an example.

A
  • a flexibility training method which incorporates vigorous swinging or bouncing movements,
  • so using momentum to move a joint forcibly through its extreme range of motion

eg bouncing to touch your toes

31
Q

whats a positive and negative of static stretching?

A

+ can be used in a cooldown to return the muscle to its resting length

  • should not normally be used in a warmup as it can reduce the speed and force of contraction
32
Q

whats an advantage of dynamic stretching?

A

it increases the speed of contraction

which makes it useful in warmup

33
Q

whats a disadvantage of ballistic stretching?

A

can lead to injury if the performer is not already flexible.

34
Q

what are two physiological adaptations of flexibility, explain?

A
  1. increased resting length of muscle and soft tissue.
    - increased range of motion at the joint
  2. increased elasticity of the muscle and soft tissue.
    - static and dynamic flexibility are improved
