Title: Core%20Stability


1
Core Stability
  • Not just a good 6 pack

2
Core Stability
  • What is core stability
  • Muscles involved
  • Linked to functionality
  • Exercises

3
Fitness parameters
  • Six parameters to overall fitness
  • Cardiovascular
  • Strength
  • Proprioception
  • Flexibility
  • Stability
  • Endurance

4
What is Core Stability?
  • Core muscles enable us to stand upright
    (stabilisers) and move on 2 feet (mobilisers).
  • A strong core distributes stress of weight
    bearing and protects the spine.
  • The neutral spine is the correct position of the
    pelvis in order to gain the maximum benefit from
    exercise.

5
Muscles Involved
  • The Core relates to the bodily region bounded
    by the abdominal wall, the pelvis, the lower back
    and the diaphragm and its ability to stabilise
    the body during movement.

6
Muscles Involved
  • Local Stabiliser muscle responsible for
    stability of each segment of spine, correct
    position
  • Global Stabiliser muscle responsible for
    control or stabilising joint movement
  • Global Mobiliser muscle involved in moving
    body, trunk and limbs

7
Muscles Involved
Midline
Side of body
Superficial Layer Global Stabiliser
Intermediate Layer Global Stabiliser
Deep Layer Local Stabiliser
8
Muscles Involved
Tendinous Intersections fibrous and allow
epigastric vessels to pass along posterior wall
Rectus abdominus Mobiliser
Can have fab superficial abs but poor deep
transverse and lower abdominal control
9
Muscles Involved
  • Close proximity to deep pelvic hip muscles and
    lower back muscles
  • Lumbar multifidus joins from vertebrae to back
    of pelvis
  • Psoas major from vertebrae round to front of hip
    into femur- flex thigh at hip joint, flex trunk
    on the hip
  • Iliacus from iliac crest down front of hip into
    femur
  • ALL CONTRIBUTE TO
  • CORE STABILITY

Link with Functionality
Static posture Relies on the length, strength
and tension of the stabilising muscles.
11
Link with Functionality
  • Dynamic Posture Relies on a ideal balance
    between agonist (prime mover/working muscle) and
    antagonist (muscle that opposes the agonist)
    allowing controlled balanced movement.

12
Link with Functionality
  • The focus of stability work now concentrates on
    the strength of tranversus abdominus, hip and
    deep back muscles. This strength precedes normal
    movement patterns and function of the upper and
    lower limbs.

13
Link with Running
  • Decreased lumbar-pelvic strength(core stability)
    contributes to the cause of lower extremity
    injuries in athletes, particular in females.
    Further studies are required to confirm the
    gender differences (Leetun et al 2004).
  • An association between reduced hip strength and
    LBP occurrence was observed more in females - may
    indicate the need for more gender-specific core
    programs (Nadler et al, 2002).

14
Link with Running
  • Swiss ball exercises involving isometric muscle
    actions, small loads, and long tension times are
    recommended for increases in core endurance.
  • Plyometric exercises, are recommended to improve
    proprioceptive and reactive capabilities.
  • Willardson (2007)

15
Link to Running
  • Use of Swiss Ball training positively affects
    core stability however specific exercises for
    individuals have proved most effective with
    performance. Limited research in the relation
    between Swiss Ball training and performance in
    young athletes.
  • Stanton et al (2004).

16
Individuality
  • Runners form and muscle forms.
  • All runners have different styles / patterns of
    movement this forms different systems and
    strength of muscles. e.g increased arm movement
    and trunk rotation, increases the use of oblique
    abdominal contraction and use.

17
Preventing Injury
  • Warm Up! Prepares muscles for exercise by
    increasing blood supply and increasing body
    temperature. Muscle fibres become more pliable
    therefore lessening the risk of injury. Dynamic
    range of warm up exercises important.
  • Cool Down! Returns body to pre-exercise state.
    Muscles become shortened during exercise
    therefore need to be gently stretched (10
    seconds) back to pre-exercise length.
