Compression
Types
of
Axial
True compression and tension
Collinear forces
Occurs straight through center of bone
Bending
Contains different lines of application; not collinear
Is within the same plane (coplanar)
Compression occurs on one end
Tension occurs on the other
Torsional
Contains compression, tension and shearing
This load twists around the long axis
Combined
The most common type of load

Hooke's Law

The relationship between load and deformation
(The larger the load, the greater the deformation)
Also described as friction

and Our Careers
Physical Therapy
Coaching
Physical Education
Athletic Training:
Prevention
Manual Therapy
Manipulation:
slow controlled process over a period of time
intended to improve elasticity
combination of loads usually axial and torsional
Massage:
repetitive rubbing (shearing)
used to improve interstitial fluid flow
Mobilization:
intended to loosen a restricted joint and increase its range of motion
example: glenohumeral joint mob: axial and bending load
Athletic Training:
Diagnosis
A high valgus (bending) load applied to the knee joint increases the number of knee injuries
Information obtained through this study may provide insight on loading applied to the lower extremity joints in various basketball movements

Knowledge and understanding of loads as a teacher is important to teach to students in order to have proper form and technique in all exercises and reduce the risk of injury.
While performing a squat, it is important for students to understand the compressive stress/axial load of the barbell and weight straght down against the student as the ground provides opposite force, so that they are reminded to maintain that axis from shoulders to the ground.
Excessive in sports
Understanding loads, ATCs can better assess and educate
