Intra-Individual Head Depth Variability During the Competitive Swiim Start

In the November 2012 issue of the International Journal of Aquatic Research and Education, research completed by Andres C. Cornett, Hiroki Naganobori, and Joel M. Stager is presented racing starts and water depth.  This information is timely given the recent discussions prompted by the Model Aquatic Health Code.  This study researches the potential for injury when executing a racing start.  This is the first study to quantify racing start depth by having thesame swimmer execute multiple racing starts in the same condition.  The findings indicate that racing start depth varies.  It is critical that swimmers can accurately percieve water depth and adjust accordingly.  The swimmers ability to demonstrate depth control is a critical skill set when executing compettive racing starts in shallow water.
