Shear - two parallel forces applied in opposite directions that are not in line with each other

constitute a shearing load or stress. The site of muscular attachment is the axis around which

the forces of shear develop. This becomes the “force axis” as opposed to the anatomical axis.

Shunt Muscle - directs the greater part of its contractile force along the bone it is moving

(creating greater force towards compression/stabilization). The brachioradialis is a shunt

during an arm curl.

Skeletal Muscle - muscle controlling skeletal movement that is normally under voluntary

control.

Skewing - the result of a vector shift through a limb or system.

Sliding Filament Theory - a muscle shortens or lengthens because the thick and thin

myofibrils slide past one another without the filaments changing length.

Slow-twitch Fibers - skeletal muscle fibers characterized by relatively slow contraction times

and great capacity for the aerobic production of adenosine triphosphate.

Sprain - the permanent deformation of the structure due to excessive or prolonged stress/

strain.

Spurt Muscle - directs the greater part of its force across the bone it is moving rather than

along it (creating greater effort towards motion). The biceps is a spurt during an arm curl.

Stabilizer - a muscle that steadies or supports a joint in order that another active muscle may

have a firm base upon which to pull.

Static contraction - a muscular contraction that does not involve changes in the angle of the

joint(s) involved.

Steady state - that state of physiological stability wherein the energy demands of the body

can be met relatively easily for a prolonged period of time.

Strain - the deformation of the structure as the result of stress.

Strength - the ability to exert muscular force briefly.

Stress - the force created within a structure when placed under load.

Submaximal exercise - usually exercise at less than maximal intensity, but may also refer to

exercise of less than maximal duration.

Superior - a higher position upon or within the body.
