Abstract

The purpose of this experiment was to compare different styles of underwater kicking with respect to velocity of a swimmer. Four underwater kicking styles were compared; underwater dolphins, underwater freestyle, on the surface dolphins, and on the surface freestyle. One of the largest uncertainties in the competitive swimming world is which type of underwater kick is fastest, therefore the results of this study could help clear the air of some of this controversy, by showing which type of kick is fastest for competitive swimming. The subjects used in this were asked to swim at least fifteen meters using their designated kick, and they were timed using stopwatches to measure how long it took them to kick fifteen meters of their designated kick. The hypothesis was that if the swimmer uses underwater dolphin kicking or underwater freestyle kicking, then the swimmer will have a greater velocity than if they use on the surface dolphin kicking or on the surface freestyle kicking. The results of this experiment supported the null hypothesis. In conclusion, this experiment will benefit the swimming community by displaying which type of underwater kick has the greatest velocity.
