Q

What is sagittal plane?

A

Sagittal plane - a vertical plane that divides the body into left and right sides. Flexion and extension types of movement occur in this plane, eg kicking a football, chest pass in netball, walking, jumping, squatting.

Q

What is transverse plane?

A

Transverse plane - passes through the middle of the body and divides the body horizontally in an upper and lower half. Rotation types of movement occur in this plane, eg hip rotation in a golf swing, twisting in a discus throw, pivoting in netball, spinning in skating.

Q

What is frontal plane?

A

Frontal plane - passes from side to side and divides the body into the front and back. Abduction and adduction movements occur in this plane, eg jumping jack exercises, raising and lowering arms and legs sideways, cartwheel.

Q

What is the transverse axis?

A

Transverse axis - this line runs from left to right through the centre of the body. For example, when a person performs a somersault they rotate around this axis.

Q

What is the sagittal axis?

A

Sagittal axis - this line runs from front to back through the centre of the body. For example, when a person performs a cartwheel they are rotating about the sagittal axis.

Q

What is the longitudinal axis?

A

Longitudinal axis - this line runs from top to bottom through the centre of the body. For example, when a skater performs a spin they are rotating around the longitudinal axis.

Q

What plane of movement and axis of rotation does a forward roll take place in?

A

Plane – sagittal, as there is flexion and extension of the knees, elbows, neck and spine.

Axis – transverse, as there is rotation around a line running from left to right through the centre of the body.
