QUANTIFYING CRITICAL FEATURES OF UNDERWATER STROKE TECHNIQUE IN FREESTYLE SWIMMING
Keywords: Freestyle, front crawl, swimming, interpolation, accuracy, reliability, technique
AbstractThe purpose of this study was to establish methods for accurately quantifying the time of entry, catch and release in freestyle swimming. The methods allow ready data collection, digitising and analysis without recourse to expensive cameras and diglising equipment thereby enabling analysis by coaches as well as biomechanists. Interpolation procedures to improve the accuracy of estimating the time of occurrence of the events were developed.
