A video race analysis was conducted at the Atlanta Paralympic Games swimming competition. The purpose was to describe the contribution of clean swimming speed, as well as start, turn, and finish speed, to the total race performance in the four strokes for the men’s 100 m events. Start, turn, and finish times, as well as clean swimming speed during four race sections, were measured on videotapes during the preliminary heats (329 swims). Information on 1996 Olympic Games finalists (N = 16) was also available. In Paralympic swimmers, next to clean swimming speed, both turning and finishing were highly correlated with the end race result. Paralympic swimmers do start, turn, and finish slower than Olympic swimmers but in direct relation to their slower clean swimming speed. The race pattern of these components is not different between Paralympic and Olympic swimmers.

A video race analysis was conducted on 100-m freestyle performances of 72 male and 62 female finalists at the Sydney 2000 Paralympic Games. Races were won or lost in the second half of each 50-m race lap and differences in speed between swimmers were more related to stroke length than stroke rate. Within-race speed changes were more related to changes in stroke rate. Stroke rate changes were also responsible for speed changes between qualifying heats and finals in the first part of races, while stroke length was responsible for better speed maintenance at the end of races. Results indicate that Paralympic finalists use race speed patterns similar to able-bodied elite swimmers.

The player classification system in wheelchair basketball (composed of four classes) is based on an analysis of players’ functional resources through game observation and field-testing. This study examines if the classes are in the correct proportion relative to each other. During the Wheelchair Basketball World Championships in Sydney 1998, 12 teams were videotaped for three 40-min games. Eighty-eight male players were retained for a detailed performance analysis by means of the Comprehensive Basketball Grading System (CBGS). Although a slight underestimation of the functional potential of Class II and III players was noted, it was concluded that the player classification system in wheelchair basketball proportionally represents the functional potential of the players.
