Correct posture maintains correct alignment of the weight-bearing joints.  

Correct alignment of the weight bearing joints maintains linear mechanics.  

Linear mechanics optimizes performance (strength and durability) in all sports.

Figure 1 - Uneven tire wear pattern secondary to suspension problem

In all competitive sports, biomechanics is a major determinant in performance.  More specifically, if the athlete has linear mechanics, they are able to reach their full potential in performance, strength and endurance.  If, on the other hand, the athlete has torsional mechanics, their performance will suffer, regardless of their committment and/or training schedule.

This section includes examples of athletes with and without linear mechanics. One can quickly see the impact torsional mechanics has on performance.

  • To maximize the athlete's potential, they must have linear mechanics.  If the athlete has torsional mechanics, their performance will suffer.


A good mechanical analogy is:  A car's suspension (body's alignment) problems can lead to tire (joint) failure (arthrits):

  • When the suspension of a car is out of alignment (poor posture), the weight of the car is unevenly distributed across the surfaces of the tires (weight bearing joints) 
  • Some parts of the tires (joints) receive more weight than other parts 
  • This causes the tires (joints) to wear unevenly (See Figures 1 and 2 below) 
  • The uneven thread wear pattern diminishes roadability of the tires (strength and endurance in sports is compromised) and eventually the tire will fail completely (multiple reoccuring overuse injuries finally resulting in retiring from competition).
