Biomechanics Vocab Flashcards
Kinesiology
The study of the human movement
Biomechanics
The study of how forces affects a living body.
Ground reaction force
An equal and opposite external force that is exerted back onto the body by the ground
Qualitative analysis
Applying principle of proper technique and combining them with observations in order to make an educated evaluation
Quantitative analysis
Taking a physical measurement and making mathematical computation to reach a conclusion
Anatomic position
Standard posture where the body stands upright with the arms beside the trunk the palms facing forward and a head facing forward.
Midline
An imaginary line that splits the body into an equal half
Sagittal plane
An imaginary plane that bisects the body into equals half’s produce a left half and right half.
Frontal plane
An imaginary plane that bisects the body into equals halves producing a front and the back half
Transverse plane
An imaginary plane that bisects the body into equal halves producing a top halve and the bottom halve.
What kinda of rotation happens in the sagittal plane
Medial-lateral axis
Anterior posterior axis
A straight line that cuts through the body from the front to the back
Longitudinal axis
An imaginary long straight line that cuts through the body from the top to the bottom
Range of motion
The amount of movement produced by one or multiple joints
Flexion
A bending at a joint where the relative angle between the two adjoining segments decrease
Flexion occurs in anterior direction for which body segments?
Ankle hip trunk upper extremities neck
Flexion occurs in a posterior direction for which body segments.
Knee
Ankle
Toes
Extension
A bending at a joint where the relative angle between the two adjoining segments increase
Abduction
A body segment is moving away from the midline
Adduction
A body segment is moving towards the midline
Internal rotation
Rotation of a limp or a body segment towards the middle of the body
External rotation
Rotation of a limp or a body segment away from the midline of the body
Pronation
A triplanar movement that is associated with the force of reduction
Supination
I tried plan in motion that is associated with force Production
Flexors
A muscle that produces flexion of a limb or joint
Extensors
A muscle that produces extension of a limb or a joint
Abductors
A muscle that produces abduction of a limb or a joint
Adductors
A muscle that produces a adduction of a limb or joint
Pronators
A muscle that produces pronation of a limb or a body segment
Supinator’s
A muscle that produces supination of a limb or a body segment
Prone
Body position where one is lying with the face downward
Supine
Body position where one is laying on the back and face is upward
Triple flexion
A multi joint exercise that involves flexion at the hips knees and ankles
Triple extension
A multi joint exercise that involves extension of the hip knee and ankle
Static posture
The starting point from which an individual moves
Multiplanar
Occurring in more than one plan of motion
