The Starting Position in diving is the beginning point at which a dive begins, and the point at which the dive is judged. Any movement that follows the Starting Position is considered to be a part of the dive. The Starting Position can be defined for three types of dives: standing, running and armstand.
Standing Dive Starting Position – The Starting Position for a standing dive begins when a diver stands on the front (the end that projects over the water) of a springboard or platform, either facing forward or backward. A diver should be motionless prior to the start of the dive and the arms can be in any position as long as they are in line with the body.
Running Dive Starting Position – The Starting Position for a running dive (a dive that uses a forward approach and hurdle) begins once a diver ceases all motion and is prepared to take the first step in the forward approach.
Armstand Dive Starting Position – The Starting Position for an armstand dive (only used on platform) begins when the diver places both hands on the end of the platform and both feet are off the platform. The starting potion can take place facing forward or backward.
