Biomechanics in Netball

Surface Friction

Surface friction is the resistance to motion of two moving objects or surfaces that touch.

When a force is applied to an object, the resistive force of friction acts in the opposite direction.

Centre of Gravity

Centre of gravity is the single point of your body about which every point of its mass is equally distributed.

Base of Support

Base of support is your sagittal and frontal plane projections, in this case, the position of your feet.

Angle and Height of Release Angle of release refers to

the angle at which the ball is travelling when it is released from the hands of the player.

Height of release refers to the height at which the ball is released from the players’ hands.

Sequential Force Summation

Sequential force summation is described as the combination of forces produced by different parts of the body in sequence to exert maximum force.

The strongest and lowest parts of the body around the centre of gravity will move first, followed by the weaker, lighter and faster extremities.

Backspin

If you flick your wrist forward upon release of the ball, the ball will travel spinning backwards through the air.

This can be described through the Magnus Effect.

The Magnus Effect

Direction of travel

Direction of air flow

Direction of rotation

The Magnus Effect

Flicking the wrist forward creates backspin, forcing the ball upwards to the ring.
