The Study of Human movement.
The study of how forces affect a living body.
Ground reaction force
An equal and opposite external force that is exerted back onto the body by the ground.
applying principles. Primary
Taking physical measurements. Math
Front side of body
Back side of body
Above a landmark of closest to head
located toward or closest to bottom of body
closest to the center of the body
Furthest from the center of the body
located closest to the midline of the body
farthest from midline
Left and right half
front and back half
top and bottom half
straight line that cuts through body front to back
Straight line top to bottom
Medial-Lateral or Coronal axis
line that cuts through body from shoulder to shoulder.
bending at a joint where the angle between two segments decreases. moving away from start position
two adjoining segments increases. Or returning to zero
Abduction (internal rotation)
moving away from midline
Adduction (external rotation)
moving towards midline
Triplanar motion associated with force reduction
A multijoint exercise that involves flexion in hip, knee, and ankle
A multijoint exercise that involves extension in hip, knee, and ankle
Tension while muscle shortens in length
muscle maintains constant length
muscle develops tension while lengthening.
1. A muscles primary function
2. Muscle action at joint when concentrically activated.
Action of a muscle when it is generating eccentric contraction
study of force
time that a muscle is actively producing tension during an exercise.
The speed at which each rep is preformed.
4: Eccentric phase
2: Isometric phase
1: Concentric phase
muscles that are parallel to the longitudinal axis
muscles that are at an angle to the longitudinal axis
relatively mobile attachment site
tissue that attaches muscle to bone
A white tendinous sheet that attaches muscle to bone
The incorrect or improper alignment of the joints in a body without movements.
neuromuscular patterns that lead a muscle to to be more active during a joint action.
muscle less active during joint movement
Located from outside yet act on a structure being considered
Located from within and acting directly on the structure
When space between bone on top of shoulder and the tendons of the rotator cuff rub against each other when arms raise
is backward flexion (bending), as of the hand or foot. This can also be described as bending in the direction of the dorsum.
movement of the foot in which the foot or toes flex downward toward the sole
Pronation of the foot
A combination of dorsiflexion, eversion, and abduction
Supination of the foot
A combination of plantar flexion, inversion, and adduction
When the neuromuscular system allows agonists, antagonists, and stabilizers to synergistically produce muscle action in all three planes
path of least resistance during movement
moves body directly
muscle whose action counteracts that of another specified muscle
