Basic KinesiologyKinesiology-the study of human movement
Brings together anatomy, physiology, physics, and geometry as they relate to the human bodies movement.
Basic KinesiologyBiomechanics-mechanical principles that relate directly to the human body. Can be relative to the extremities or an implement such as a bat or racket
Can be static(nonmoving) or dynamic(moving) activities.
Read paragraph 3-4 on page 3 and paragraph 1-2 on page 4
Basic KinesiologyAnatomical Position-human body standing upright, eyes forward feet parallel, arms at side, and hands with palms facing forward.Midline The line that divides the body from left and right
Kinesiology BasicsDistal- far from midlineProximal- close to midline
Kinesiology BasicsSuperior- above another structure
Inferior- below another structure
Kinesiology BasicsFront =anterior =ventral
Back =posterior =dorsal
Basic Kinesiology-types of motionLinear Motion- a straight line from one point to another.Rectilinear Motion-straight line like a player running across a field.Curvilinear Motion- straight line but in a curved path, like a diver leaving the diving board.
Basic Kinesiology-types of motionAngular Motion- Rotary motion is when all the parts of the object move through the same angle, same direction at the same time, but do not move the same distance.When you flex your elbow your hand and wrist travel a different distance through space.Basic Kinesiology-types of motionGenerally speaking most movement within the body is angular, most movement outside the body is linear.
Get into groups of 4 and create a list(use pg 6):2 linear movements2 angular movements2 combination movementsJoint MovementsArthrokinematics: relationship of joint surface movement. The humeral heads movement within glenoid fossa of scapula.
Osteokinematics: relationship of the movement of bones around a joint axis. Humerus moving on scapulaKinesiologyMovements of Synovial Joints (freely moving jts. where most joint motion occurs)Flexion-decrease angle between 2 bonesExtension-increase angle between 2 bonesHyperextension-increase angle between 2 bones beyond the normal range of motion (ROM).
KinesiologyMovements of Synovial JointsAbduction-Limbs only-limb moves away from the midline of the body.Adduction-Limbs only-limb moves toward the midline of the body.Rotation-when a bone turns on its axis towards or away from the midline of the body
Movements of Synovial JointsCircumduction- the ability of a limb to move in a circular path around an axis.Supination- moving into a supine position.Pronation- moving into a prone position.Plantarflexion- pointing toes down, planting the footDorsiflexion- bringing the toes upPalmarflexion flexing the wrist
KinesiologyMovements of Synovial JointsPlantarflexion- pointing toes down, planting the footDorsiflexion- bringing the toes up
KinesiologyMovements of Synovial JointsInversion- turns the sole of the foot inward, medially.Eversion- turns the sole of the foot outward, laterally.Protraction- occurs in the transverse plane, moving the body part forwardRetraction- occurs in the transverse plane, moving the body part backward
