Mobility vs' Stability

Mobility vs. Stability
2
Why Do Mobility Training?

• Allows your body to move in all six degrees and
  three planes of motion, therefore, giving you the
  ability to perform any motion not having to
  compensate.
• Mobility allows the generation of ELASTIC ENERGY
• and therefore, establishes a base for
  efficient power production!
• Mobility allows the adjacent segments to maintain
  STABILITY!!!!!!!

What is Stability?

• Stability is defined as the ability of any system
  to remain unchanged or aligned in the presence of
  change or outside forces.
• Stability is the combination of
• Balance
• Strength
• Muscular Endurance

4
The Joint by Joint Approach

• First noted by Mike Boyle and Gray Cook.
• The body works in an alternating pattern of
  stable segments connected by mobile joints.
• If this pattern is altered dysfunction and
  compensation will occur.

Testing Mobility can Predict Stability

• Poor mobility can lead to muscle imbalances
• Poor mobility can force stable segments to become
  mobile segments (example - limited hip range of
  motion can cause the lumbar spine to become
  unstable!)
