Change of the age and performance of swimmers across World Championships and Olympic Games finals from 1992 to 2013 - a cross-sectional data analysis In 1988, Schulz and Curnov published a work to the age of top athletes.In doing so, they examined the Olympic champion from 1896 to 1980 in the freestyle swimming.Over every year, the age of the best women was 18 years and the best men at 21 years. Since newer numbers are missing, we have examined the age of the best swimmer at the World Cup (1994-2013) and Olympia (1992-2012).Due to current information is to be assumed that the top swimmers were a bit older over the last few years.
In fact, the average age of the finalists at the World Cup rose, except in 200 m women, 400 m freestyle men and 200 m breast men where the average age became younger. Even on Olympia, the average age rose, with the exception of 800 m freestyle women and 400 m were men.
