Movement Analysis (PAPER 1) Flashcards
what is the sagittal plane? what movements are allowed?
The sagittal plane divides the left and right side of the body, vertically.
Flexion
&
Extension eg sommersault
what is the frontal plane? what movments are allwed?
The frontal plane divides the front and the back of the body, vertically.
Abduction
&
Adduction
eg cartwheele
what is the transverse plane? what movments are allowed?
The transverse plane divides the top and the bottom of the body, horizontally.
rotation eg pirouette
what is the sagittal axis? and what does sit allow?
The sagittal axis passes horizontally through the body from front to back, allowing rotation
what is the frontal axis? and what does it allow?
The frontal axis passes horizontally through the body from left to right, allowing rotation
what is the vertical axis? and what does it allow?
The vertical axis goes from top to bottom.
rotation of the body in an upright position.
what is a plane?
an imaginary line diving the body in two.
what is an axis?
an imaginary line around which a body or body part can turn
three types of lever systems:
First Class 1 F
Second Class 2 L
Third Class 3 E
There are 3 main components to a lever:
Fulcrum
Load
Effort
Fulcrum
the fixed pivot point (joints)
Load
the weight/resistance to be moved (object/body weight)
Effort
The source of energy that will do the work (muscles)
examples of first class leavers:
The fulcrum lies between the effort and load.
Extension in a Tricep dips
example of a second class leaver
The load lies between the fulcrum and the effort
ANKLE ONLY
When jumping or moving upwards the gastrocnemius provides the effort to push the ball of the foot, lifting the body in the air.
