Abstract
The performances of the women's 200 m freestyle at the Sydney Olympic games (final and semi-final) were studied using 12 video cameras. The four 50 m velocities, stroke frequency, stroke length, and turn velocities were calculated using a specific competition analysis computer program. The medallists swam faster than the non-medallist finalists only in the first 50 m. There was no other statistical difference for the start or turns velocities. For the 16 swimmers, the 200 m freestyle velocity was mainly related to the velocity of the third 50 m lap (r = 0.83;
