Trauma - ANSWER physical injury or wound sustained in sport, produced by internal or
external force
Mechanical injury - ANSWER _______ results from force or mechanical energy that
changes state of rest or uniform motion of matter
Load - ANSWER Tissue properties: an external force acting on the body causing
internal reactions within the tissues
Stiffness - ANSWER Tissue properties: Ability of a tissue to resist a load
Greater stiffness = greater magnitude load can resist
Stress - ANSWER Tissue properties: Internal resistance to a load
Strain - ANSWER Tissue properties: Internal change in tissue (i.e. length) resulting in
deformation
Yield point - ANSWER Point at which elasticity is almost exceeded
Elasticity - ANSWER property that allows a tissue to return to normal following
deformation.
Toe region - ANSWER region where there is straightening of collagen fibers
1
, Elastic range - ANSWER range where fibers require substantial tension to deform and
will return to original shape after stretch
Plastic range - ANSWER range where stretched fibers will not return to original length
(partial tearing of fibers)
Tension - ANSWER Force that pulls and stretches tissue
Compression - ANSWER Force that results in tissue crush - two forces applied towards
one another
Shearing - ANSWER Force that moves across the parallel organization of tissue
Bending - ANSWER Two force pairs act at opposite ends of a structure (4 points)
Torsion - ANSWER Loads caused by twisting in opposite directions from opposite ends
inert (noncontractile) and contractile tissue - ANSWER Soft tissue or non -bony tissue
is categorized as:
Noncontractile - ANSWER _______ tissues include, ligaments, skin, cartilage, capsules,
fascia, dura mater and nerve roots
Contractile - ANSWER _____tissue involves muscles and its parts including tendons
and bony insertions
Skin Injuries - ANSWER Break in the continuity of skin as a result of trauma
