18
Q

Static balance

A

The ability to hold a steady position (standing on one leg)

19
Q

Dynamic Balance

A

Ability to maintain equilibrium while in motion. (riding a bike)

20
Q

Why is balance important?

A

For Health and Performance

21
Q

How balance affects health?

A

Poor balance can cause falls and injury

22
Q

How balance affects performance

A

Sport and daily activities of living are affected.

23
Q

Factors that affect balance

A

Body weight, Strength, Centre of Gravity, Fear, Co-ordination, Environmental Factors

24
Q

How are risk of falls related to Dynapenia and Sarcopenia

A

Increased fall risk is related to Dynapenia (muscle strength loss) and Sarcopenia (muscle mass loss)

25
Q

How to Improve Balance

A
  • Add Instability
  • Adding balance elements mean reducing total intensity
  • Narrow base of support
26
Q

Define Flexibility

A

Range of motion about the joint or joints

27
Q

Is flexibility a full body phenomenon?

A

No; it’s catered towards specific joints.

28
Q

Importance of Flexibility

A

Better performance with ADLA, Sport, QoL, Leisure Time PA, and function and independence

29
Q

What are limitations to flexibility

A
  • Mechanical and Anatomical Factors (body mass)
  • Joint Tissue Laxity
  • Inactivity
  • Age
  • Temperature
30
Q

What is joint tissue laxity?

A

Genetic disease where you’re too flexible and this can reduce stability of a joint

31
Q

Measurements of Flexibility?

A

Goniometry and Performance measures (sit and reach)

32
Q

Active Range of Motion

A

Voluntary movement; how much you can move or stretch something.

33
Q

Passive Range of Motion?

A

Aid provides additional force to active range of motion.

34
Q

What is key to static stretching?

A

Doing it after your warm-up

35
Q

Why should you static stretch after your warm-up?

A

Because tissues are warm and range of motion is increased; static stretching then would cause less possible injury

36
Q

How quick should a static stretch be?

A

Should be slow and passive (10-30 sec per stretch)

37
Q

When should a dynamic stretch be done?

A

During the warmup.

38
Q

What does dynamic stretch involve?

A

Active Movement

39
Q

Proprioceptive Neuromuscular Facilitation (PNF)

A

Type of stretching; doing techniques that contract and relax the muscle

40
Q

Purpose of PNF

A

Increase Range of Motion

41
Q

Why is static stretching seen as negative for sprinting?

A

Static seen as less elastic and decreasing muscle addition which is opposite of what we want for sprinting.

42
Q

Is Dynamic stretching seen as negative?

A

No; overall dynamic stretching should be done first before static.

43
Q

What points are made on the paper on flexibility and physical fitness

A
  • Working on flexibility has no meaning if focusing on resistance and aerobic.
  • Stretching does not need to be standard prescription of exercise
