BASIC KINESIOLOGY Kinesiology-the study
of human movement
Brings together anatomy, physiology, physics, and geometry as they relate to the human bodies movement.
BASIC KINESIOLOGY Biomechanics-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 KINESIOLOGY Anatomical
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 Basics Medial-Middle/Midline Lateral-outside
Kinesiology Basics
Distal- far from midline Proximal- close to midline
Kinesiology Basics Superior- above another
structure
Inferior- below another structure
Kinesiology Basics
Front =anterior =ventral
Back =posterior =dorsal
BASIC KINESIOLOGY-TYPES OF MOTION Linear 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 MOTION Angular 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 MOTION Generally 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 movements 2 angular movements 2 combination movements
JOINT MOVEMENTS Arthrokinematics: relationship of joint
surface movement. The humeral head’s movement within glenoid fossa of scapula.
Osteokinematics: relationship of the movement of bones around a joint axis. Humerus moving on scapula
Kinesiology Movements 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).
Kinesiology Movements of Synovial Joints
Abduction-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 foot”Dorsiflexion- bringing the toes upPalmarflexion – flexing the wrist
KinesiologyMovements of Synovial Joints
Plantarflexion- pointing toes down, “planting the foot”
Dorsiflexion- bringing the toes up
Kinesiology Movements of Synovial Joints
Inversion- 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
Kinesiology Movements of Synovial Joints
Shoulder Abduction – movement of the arm away from the body
Shoulder Adduction - movement of the arm toward the
bodyShoulder Horizontal Abduction – Shoulder
abducted to 90 degrees, then adduct toward midline
Shoulder Horizontal Adduction – Shoulder abducted to 90 degrees,
then adduct toward midlineRadial Deviation – wrist deviates laterallyUlnar deviation – wrist deviates medially
