Abstract. A computer application that supports the teaching and learning of sportingtechniques is presented. It was developed as a tool to assist sports trainers in identifying,analyzing, relating, and evaluating the learning of sporting techniques. At times trainers fail tovisualize all the details of an athlete’s technical gestures, mainly because of the speed of themovements. Based on this concept of observational method, the developed software is simpleto use and includes digital videos in a natural form for trainers who are not computer experts.To select an adequate video format for analyzing sporting techniques, compression tests andvideo compression with different codecs were made. Once the format had been chosen, itscompression was tested at different video qualities with the selected codec. To verify thefunctionalities of the developed tool, the chosen sport was swimming. The results obtainedwith the tool had excellent usability, since most of the functions were mastered withoutproblems by the trainers.
