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. [ABSTRACT FROM AUTHOR] |
