How Does it Work


Biomechanics is as the name implies the application of physical laws to living entities.  More specifically, it involves the forces exerted by muscles and gravity on the skeletal structure.  In basic terms it is the science of finding mechanical, positional and structural abnormalities and not just negating them but optimizing them.  So if for example you had a foot that flattened or rolled in when standing, the key would be not to just prevent it from rolling in so that it was the same as most other people’s feet, but rather to make that foot function in its ideal or optimal position for maximum performance.

This is what Precision Sports Inc. specializes in.  Namely, making you as structurally perfect as is humanly possible to improve performance, decrease the risks of injuries and prevent arthritic symptoms.  Our goal is to give your trainers, instructors, coaches or even yourself a better specimen to work with.

Our work is based upon the following premise: 

  1. No one is structurally perfect.  Everyone has some degree of abnormality. 
  2. Any degree of abnormality decreases performance, increases the risks of injuries and can later cause arthritic changes
  3. All sports performance begins and ends with the foot
    1. It is the foundation of the skeletal system
    2. If it is not aligned optimally, all of the weight bearing joints (ankles, knees, hips and low back) will be out of alignment
    3. Structural analysis must begin with the foot
  4. Optimally controlling structure and function increases performance, decreases the risks of injuries and later arthritic changes

Based upon the above premise, we evaluate three basic components to achieve ultimate performance: 

  1. Structural alignment
  2. Flexibility assessment (lower extremity)
  3. Stability (even weight distribution)

As mentioned above, structural analysis must begin with the foot.  As the foundation of the entire skeletal system, its position is of great importance in all aspects of sports performance regardless of the particular sport.   We therefore carefully evaluate foot structure and its overall position.  Do the feet flatten (pronate) or roll outward (supinate)?  Do they both function the same or are you in essence driving your car with a 22 inch wheel on your front left and an 18 on your front right?

Another common structural abnormality that is evaluated is limb length discrepancies (one leg being longer than other).  Everyone has one leg longer than other.  Some are positional while others are structural abnormalities.  Many people do not have a problem with this, while others can have significant damage to their weight bearing joints (feet, ankles, knees, hips and low backs) due to this problem.  And it can greatly effect sports performance.  For example, in golf this can be the major reason for swing problems.  For example, if you are a right handed golfer and have a longer left leg, you cannot ever really get through your golf swing since you are in essence always trying to swing on an uphill lie.  Often, simply putting the correct lift under the right heel of your foot can make a significant difference. Often such corrections can greatly impact the X factor.

A detailed muscle examination is also performed.  Tight muscles, especially in the calf are a common problem in most athletes.  This can cause shin splints (pain in the front of the legs), calf soreness, and painful arches and become a real fatigue factor.  Often stretching doesn’t seem to fully help.  We have developed a unique trigger point injection that almost always remedies this condition immediately and is usually very long lasting if followed by proper stretching exercises.

We utilize a simple squat test.  Individuals with a longer leg will be seen to have one leg move inward as they squat.  Those with flat feet will have both knees move inward.  Simply fixing these abnormalities have dramatic results in  having the knees stay on the frontal plane as they squat and show much greater balance and stability.  It is something that can be felt and seen immediately.

Simple tests are conducted such as swinging a golf club or baseball bat - barefoot and then with corrections we have you stand on; much like trying on eyeglasses.  Once the right prescription is determined a lift may be recommended, appropriate stretching exercises taught or a highly specialized, unique, balance enhancing shoe insert .
