To compare the 2000 to 2008 Olympic male and female 100m swim performance and results. Methods: There were collected total 48 between 2000-2008 Olympic Games final male and female results. Using One-way ANOVA, Pearson product moment correlation to examine the score differences and correlation between these groups. Results: The male and female 2008 100m freestyle scores were significantly better then 2000 and 2004 (F = 18.45, p < .05; F = 7.23, p =. 001 < .05). In sub-comparison results showed that female’s first 50 meters score 2008, male react time, first and final 50 meters score were significant better then 2004 and 2000. The correlation between each sub-score were male reaction time, first and final 50 meters; female first and final 50 meters were significant correlation final result. Conclusions: segmentation results can predict the results, and it can be and reference at speed and intensity of training.
