technique

The aim of this study was to quantify the passive and active drag forces in front crawl swimming at the swimmer's maximum swimming velocity and to present this data as a force-time profile. This method enabled the minimum and maximum force with respect to the phase within the stroke to be identified. Elite freestylers (n=18) completed three maximum swim velocity time trials to determine their maximum velocity. This was followed by three passive drag trials and three active drag trials using a towing device mounted upon a force platform. The computed active drag and the propulsive force profiles were represented as a forcetime graph, allowing identification of intra-cyclic force fluctuations. The force-time profiles were synchronised to video footage which provided unique quantitative stroke mechanic feedback to the elite coaches and athletes.
