Planes of Motion Flashcards
Name the 3 planes of motion
Frontal, Sagittal, Transverse
What is the Frontal Plane?
The vertical plane that divides the front and back halves of the body
What is the Sagittal Plane?
The vertical plane that divides the left and right halves of the body
What is the Transverse Plane?
The horizontal plane that ddivides the top and bottom halves of the body.
Give an example of movement that occurs in the Frontal Plane
Abduction of Adduction of limbs
Define abduction
The motion observed when a limb moves AWAY from the midline.
Define adduction
The motion observed when a limb moves TOWARDS the midline
Give an example of movement that occurs in the Sagittal Plane
Flexion and Extension of the hip and trunk
Define extension
When the angle of of the bones comprising a joint INCREASES
Define Flexion
When the angle of the bones comprising a joint DECREASES
What is the exception to the Extension and Flexion angle ruling?
The shoulder. Shoulder Flexion is when the arm moves overhead. Shoulder Extension is when the shoulder returns from overhead OR moves behind the body
Give an example of a movement that occurs in the Transverse Plane
Rotation of the head or trunk
What is Circumduction?
The combination movement of all 3 planes of motion.
Give an example of Circumduction you may use in a warm up
Arm Circles, Leg Circles, PVC Pass Throughs

What is an OPEN Kinetic Chain?
When the Distal end of the moving body part is free and mobile. (Shoulder Press)
What is a CLOSED Kinetic Chain?
When the Distal end of the moving body part is immobile, i.e. Fixed to the floor (Squat, Deadlift, HSPU)
What is a COMBINATION Kinetic Chain?
When both an Open and Closed Chain are happening at the same time. Jerk, Snatch,
