The effects of course length on freestyle swimming speed in elite female and male swimmers – a comparison of swimmers at national and international level Swimming in the pool can be completed at 25m and 50m bassin.We have investigated the performance of floors at national level (Switzerland) and international level (World Cup finals) for all routes from 50m to 1'500m. On the short-run, men like women of both levels were average 2.0 ± 0.6% faster.Gender differences were greater than the short-run greater than on the Langbahn for floats of both levels of 50m to 800m. Over the years, men and women at an international level were faster during the national level only the men were faster, but with the exception of the 800m and 1'500m on the short-run.Woman at national level were only over 50m, 100m and 1'500m over the years faster.
