PFT4.txt

A study that uses principles of physics to quantitatively study how forces interact within a living body

Position above a point of reference

Position below a point of reference

Positioned nearest the center of the body, or point of reference

Positioned farthest from the center of the body or point of reference

On the front of the body

On the back of the body

Positioned near the middle of the body

Toward the outside of the body

Positioned on the opposite side of the body.
Ex: the right foot to the left had

Positioned on the same side of the body
Ex: the right foot to the right hand

An imaginary bisector that divides the body into left and right halves

The bending of a joint causing the angle to the joint to decrease

The straightening of a joint causing the angle to the joint to increase

An imaginary bisector that divides the body into front and back halves

Movement of a body part away from the middle of the body

Movement of a body part toward the middle of the body

An imaginary bisector that divides the body into top and bottom halves

Rotation of a joint toward the middle of the body

Rotation of a joint away from the middle of the body

Movements in the sagittal plane include
_________ and ______.

Movements in the frontal plane are ________ and ______.

Movements in the transverse plane are _____ and ____ .

Moving in the same direction as the resistance
Decelerates or reduces force
lengthening of the muscle

No visible movement with or against resistance
Dynamically stabilizes force
Muscle maintains a certain length

Moving in the opposite direction of force
Accelerates or produces force
Shortening of the muscle

An interaction between two entities or bodies that result in either the acceleration or deceleration of an object.

The length at which a muscle can produce the greatest force. There is an optimal length at which the actin and myosin filaments in the sarcomere have the greatest degree of overlap results in the potential for maximal force production.

The ability of muscles to produce force with increasing velocity. As the velocity of a concentric muscle contreaction increases its ability to produce force decreases. Conversely as the velocity of muscle actions increases with eccentric muscle action , the ability to develop force increases.

The synergistic action of muscles to produce movement around a joint. All muscles working together for the production of proper movement are said to be working this.

To ensure that the kinetic chain moves in the right manner, it must exhibit proper _______ relationships. This can only happen if the muscles are at the right ___________ relationships and the joints have proper __________ (joint motion).

Movement of the bones and joints. The levers (bones) rotate arount the axis (joints).

Turning effect of the joint

>Is concerned with those neural structures that are involved with motor behavior and how they produce movement.
>The study of posture and movements and the involved structures and mechanisms that the central nervous system uses to assimilate and integrate the sensory information with previous experiences.

Groups of muscles that are recruited by the central nervous system to provide movement

% of population that experiences low back pain
# ACL injuries that occur yearly

The cumulative sensory input to the cns from all mechanoreceptors that sense position and limb movements.

The ability of the nervous system to gather and interpret sensory information and select and execute the proper motor response.

repeated practice of motor control processes, which lead to a change in the ability to produce complex movements.

the use of sensory information and sensorimotor integration to help the kinetic chain in motor learning

The process whereby sensory information is used by the body via length-tension relationships (posture), force-couple relationships, and arthrokinematics to reactively monitor movement and the environment.
