2009 Rule Changes
7-4-11, 7-5-18: Deletes the option for the event judge to place a cloth marker on the crossbar for sighting purposes.
Rationale: The current crossbars are of a bright contrasting color which no longer present a sighting problem for competitors and therefore the use of the cloth is no longer in use for competition.
7-5-3 Note new: Visible etchings which appear on poles shall not meet the requirement of the manufacturer's pole rating appearing on the pole in a contrasting color.
Rationale: Most poles have an etching on the pole which is a code to the manufacturer. This code most frequently does not correspond to the proper weight rating for the pole. The rating appearing as the mark in contrasting color is established by the manufacturer is clearly visible and serves only this purpose. The requirement is for purposes of risk minimization and should be adhered to strictly.
7-5-29: Clarifies the original intent to permit a competitor in the pole vault to abort the approach and in stopping plant the pole and momentum causes his/her feet to leave the ground without being considered a foul. It is a foul if a vaulter leaves the ground in an attempt and fails to clear the crossbar.
Rationale: The change in 7-5-29 last year by the committee was not intended to allow a vaulter to abort a vault but rather to have the opportunity to stop and abort the approach. However, the language was not clear and as written allowed a vaulter to abort a vault. This change clearly reflects the original intent of the committee to abort only the approach and have the opportunity to restart the approach. This exception is appropriate for the high school vaulter.
