Q

List or describe several examples when a basic biomechanical movement analysis could add value
to the needs of a client or athlete.

A
  • They are learning a new skill or technique;
  • They have movement limitations due to disability or disease;
  • They have a persistent, recurring injury;
  • They are about to commence an exercise program from a sedentary lifestyle;

Q

Define what is meant by the term ‘Movement asymmetry’.

A

Movement which is not symmetrical

E.g. Having a dominate hand

Q

Do all movement asymmetries relate to dysfunction and/or injury?

A

No, humans are naturally asymmetrical (both in movement and anatomically), and those asymmetries can actually be beneficial at times.

Q

If a client demonstrates an asymmetry with no pain, should this asymmetry be rectified? Explain
your answer

A

If no pain exists and the asymmetry due to a structural difference, then it is often best to leave it alone.

  • Changing mechanics may actually trigger pain or injury
  • Forcing an unnatural (for them) biomechanical position can = disaster.
  • A slight malalignment, body position shifts or goofy foot positioning doesn’t mean a fix or change is needed.

Q

As an exercise science graduate, is it beyond your scope of practice to perform a basic movement
analysis to screen for asymmetry or movement irregularity?

A
  • Screen for asymmetry, dysfunctional movement / technique or movement associated with injury / pain.
  • Perhaps cue / advise correct movement patterns.
  • Refer for specialist analysis!!

Q

Describe how biomechanical features of an Mesomorph body physique could affect sports
performance or talent identification.

A

Q

Provide several examples and explain how being short or having short limbs can provide a
biomechanical advantage to sporting performance.

A

Height advantage
- Gymnastics, Diving (reduce moment of inertia to tuck body in and spin faster)

Increased agility

Q

Provide several examples and explain how a small body mass can provide a biomechanical
advantage to sporting performance.

A
  • Gymnastics, Ballet, Jockey

- Cycling – hill climbing

17
Q

Explain why each sport science discipline should not be considered / practiced in isolation

A

Many inter-relation effects and consequences exist.
Example:
-

18
Q

Provide and explain several examples how the sub-disciplines of sport/exercise science can interrelate. Try to come up with different examples to those presented in the lecture material.

A
  • Modify diet (Nutrition) & train for fat loss (Exercise prescription) = decreased mass & Inertia (Biomechanical principle) = jump higher.
19
Q

With respect to disease and disability, define a biomechanical principle and explain how that
principle may relate to movement associated a range of different disabilities and diseases. Note:
you can explain a different principle for each disability and disease if you wish. Try to come up with
different examples to those presented in the lecture material

A

Diseased:

  • Osteoporosis: Increase wt. bearing loading activities
    • Engage exercise against gravity or mass resistance
  • Osteoarthritis: Decrease joint loading forces
    • Alter stride length & joint ROM
    • Reduce total body fat mass

Disabled:

  • Amputee with prosthetic: Altered stride length & joint loadings
    • Gait analysis & training
    • Measure and modify movement
  • Cerebral palsy: Altered stride length & joint loadings
    • Gait analysis, surgery & re-training
    • Measure and modify movement
  • Downs Syndrome: Low muscle tone / strength;
    • Impacts balance, gait, exercise, terrain navigation (hills, stairs) etc
