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
