The changes in age of peak swim speed for elite male and female Swiss freestyle swimmers between 1994 and 2012
2014
This study determined the age and its changes across years of peak swimming performance from 50 to 1,500 m freestyle. Data of 70,059 Swiss freestyle swimmers (33,725 women and 36,334 men) aged 10-40 years and competing from 50 to 1,500 m were analysed. The association between age and swimming speed of the annual ten fastest swimmers was investigated using single and multi-level hierarchical regression analyses. For women, age of peak swimming speed increased in 50 m from 18.9 (s = 2.3) to 20.4 (s = 4.2) years but decreased in 1,500 m from 25.0 (s = 13.1) (1996) to 18.1 (s = 3.7) years. For 100-800 m, age remained at 19.1 (s = 1.1), 19.3 (s = 1.1), 18.7 (s = 1.5) and 18.5 (s = 1.3) years, re…
