ABSTRACT
During the 1991 World Championships and the 1992 Ólympic Games, swimmers in lane four were videotaped with a four camera system (two above water and two cameras underwater) at approximately the 40–45m mark of the pool. The four videotapes were digitized to create a 14 segment, three-dimensional model of the body during one stroke cycle [1]. The center of mass (using cadaver data [2]) and several body position angles were calculated. Hand reaction forces were calculated [3]. Landmark data were differentiated and all parameters were used to described stroke technique. The comparisons below are made within a gender and within a race distance.
