Biomechanical Principles Crossword

the rate at which speed changes
the muscle most directly involved in creating movement
the body standing erect with arms down and palms forward
the angle between the overall muscle and its fibers
the angle through which an object rotates
an object's rotational speed
a muscle that can slow down or stop a movement
the mechanical analysis of biological systems
when a muscle shortens because its contractile force is greater than the resistive force
when a muscle lengthens because its contractile force is less than the resistive force
the resisting force encountered by an object moving through a fluid or by a fluid moving past or around an object
the resistive force encountered while attempting to move two surfaces in contact relative to each other
a vertical plane dividing the standing body into anterior and posterior halves
the pivot point of a lever
the force required to accelerate an object (mass x acceleration)
when muscle length does not change because the contractile force is equal to the resistive force
an object that, when subjected to a force whose line of action does not pass through its pivot point, exerts force on any object impeding its tendency to rotate
an arched back
the ratio of movement arm through which an applied force acts to that through which a resistive force acts
the perpendicular distance from the line of action of a force on a lever to its fulcrum
force generated by biomechanical activity which tends to drawthe opposite ends of a muscle towards each other
a muscle whose fibers have featherlike arrangement
the time rate of doing work (work / time OR force x velocity)
force which acts contrary to muscle force (gravity, inertia, friction)
rotational work per unit of time or torque times angular velocity
the product of torque and angular displacement
a vertical plane dividing the standing body into left and right halves
the concept that training is most effective when resistance exercises bear key similarities to the sports activity in which the improvement is sought
