The goal of this paper was to investigate how individual medley events are swum differently from 2000-2011 era to 2012-2022 era. We focused at major international meets during these eras to analyze how 200m and 400m individual medley events have changed. The meets selected include major world events – Olympics, World championships; the premier continental events – European championships, Pan Pacific Games; as well as major country-specific events – US and Australian Olympic trials. A 2-way statistical analysis of variance across gender [men vs women] and positions [medalists vs finalists vs semifinalists]) was performed for individual strokes of the medley. The means were compared with the Bonferroni post hoc test. The correlation between the individual split time of a stroke and final time was per- formed by using Pearson’s simple correlation coefficient. Us- ing this data, trends were compared between the two papers. The results show that men and women swim the short-axis strokes, breaststroke and butterfly, faster than the long-axis strokes. This study shows that overall breaststroke during 2012-2022 is more correlated than it was during 2000-2011 and is a particularly dominant determinator for 400m Men races. Finally, Men and Women use more positive pacing for 200m and more even pacing strategy for the 400m events. These findings can be used by coaches to fine tune their training strategies.
