Levers, planes and axis

Planes and axis (recap on levers)

1st class lever (F)

Load coming from the ball.

Fulcrum is the elbow.

Effort is from the triceps.

2nd class lever (L)

Effort coming from gastrocnemius muscle.

Load of bodyweight going down to ankle/foot.

Fulcrum is the foot using plantar flexion.

3rd Class lever (E)

Fulcrum at the elbow.

Effort from the biceps as it joins BEFORE the elbow.

Load from the weight in the hand.

Multiple Choice

What movement from the following occurs around this axis?

• Skipping

• Running

• Pirouette

• Squatting

Planes and Axis

• We need to be able to identify different planes and axes.

• Be able to describe the movements in each plane and axes.

• Provide examples of each (sporting)

Planes

• An imaginary line/flat surface used to divide the body.

• 'Direction of movement'

• 3 main planes, each allows a specific type of movement.

Multiple Choice

Movements in the sagittal plane are in what directions?

• side to side movements

• forward and backward movements

• rotational movements

Multiple Choice

What is the definition of the sagittal plane?

• divides the body into left and right

• divides the body into front and back

• divides the body into top and bottom

Multiple Choice

A forward roll would be an example of a movement in the transverse plane, true or false..?

• True

• False

Multiple Choice

What of movement works along the Transverse Plane?

• Flexion

• Adduction

• Abduction

• Rotation

Open Ended

Imagine you are standing between two walls, with your back against one and your chest against the other, what movements are possible from here? (try to use the proper terminology)

Multiple Choice

What of movement works along the Frontal Plane?

• Adduction

• Rotation

• Extension

• Flexion

Multiple Choice

What is a sporting example of a movement along the Frontal Plane?

• Boxing Uppercut

• Rugby Tackle

• Cartwheel

• Front Somersault

Axes

• Direction of rotation

Frontal axis

• Line passes horizontally through hips.

• Movement only forwards and backwards similar to table football.

• Forward rolls, sommersaults ect.

Saggital axis

• Line passes horizontally through body from front to back (bellybutton).

• Causes rotations left/right.

• Cartwheel

Vertical axis

• Line going vertically through body head to toe.

• Causes a pirouette type rotation (kebab).

• Pirouette, hammer throw.
