Levers and Movement Analysis

Planes and axes of rotation

  • 3 things to know
  • AS Unit 1

Overview

The sagittal, frontal and transverse planes, the longitudinal, transverse and anterior-posterior axes, and the plane and axis of a front somersault, a cartwheel, a discus turn, running and a star jump.

Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is a plane of movement?

    Model answer

    A plane is an imaginary flat surface that divides the body. Movement takes place along a plane.

  2. 2

    What is an axis of rotation?

    Model answer

    An axis is an imaginary line about which the body or a body part turns. Each axis passes at right angles through a plane.

  3. 3

    What is the sagittal plane?

    Model answer

    The sagittal plane runs vertically from front to back, dividing the body into left and right halves. Flexion and extension take place in this plane.

  4. 4

    What is the frontal plane?

    Model answer

    The frontal plane runs vertically from side to side, dividing the body into front and back halves. Abduction and adduction take place in this plane.

  5. 5

    What is the horizontal, or transverse, plane?

    Model answer

    The transverse plane runs horizontally, dividing the body into upper and lower halves. Rotation takes place in this plane.

  6. 6

    What is the longitudinal axis?

    Model answer

    The longitudinal axis runs vertically from the top of the head to the feet. Movements in the transverse plane turn about this axis.
