Analysis of sex differences in open-water ultra-distance swimming performances in the FINA World Cup races in 5 km, 10 km and 25 km from 2000 to 2012
2014
International audience; BACKGROUND: The present study investigated the changes in swimming speeds and sex differences for elite male and female swimmers competing in 5 km, 10 km and 25 km open-water FINA World Cup races held between 2000 and 2012. METHODS: The changes in swimming speeds and sex differences across years were analysed using linear, non-linear, and multi-level regression analyses for the annual fastest and the annual ten fastest competitors. RESULTS: For the annual fastest, swimming speed remained stable for men and women in 5 km (5.50 ± 0.21 and 5.08 ± 0.19 km/h, respectively), in 10 km (5.38 ± 0.21 and 5.05 ± 0.26 km/h, respectively) and in 25 km (5.03 ± 0.32 and 4.58 ± 0.27…
Age of peak swim speed and sex difference in performance in medley and freestyle swimming – a comparison between 200 m and 400 m in Swiss elite swimm…
2013
Vaso, M., Knechtle, B., Rust, C.A., Rosemann, T. & Lepers, R. (2013). Age of peak swim speed and sex difference in performance in medley and freestyle swimming ‐ A comparison between 200 m and 400 m in Swiss elite swimmers. J. Hum. Sport Exerc., 8(3), pp.954-965. The aims of the present study were to examine (i) the age of peak swim speed and (ii) the sex difference in peak swim times in 200m and 400m medley versus freestyle. Swim times and ages of 5,524 swimmers (2,785 males and 2,739 females) from the Swiss high score list from 2006 to 2010 were analyzed using one-way analysis of variance (ANOVA). The age of peak swim speed was younger for females (~20-21 years) compared to males (~22-25 …
Changes in transition times in ‘Ironman Hawaii’ between 1998 and 2013
2014
International audience; BackgroundRecent findings showed that elite Ironman triathletes competing in ‘Ironman Hawaii’ improved both split and overall race times. The present study investigated whether elite athletes also improved in transition time (i.e. time needed between disciplines for changing clothes and equipment).MethodsChanges in split times, overall race times and transition times (i.e. expressed in absolute and relative terms) in the annual fastest competing in ‘Ironman Hawaii’ were investigated using linear, non-linear and multi-level regression analyses. To detect a potential difference in transition times between different race distances, we compared transition times in ‘Ironm…
Analysis of marathon performances of disabled athletes
2013
Le but de cette etude etait d’analyser la participation et les performances sur marathon des athletes handisports en fauteuils roulants classiques (WC) et en fauteuils avec pedalage des bras ou Handbike (HC). L’âge et les performances chronometriques de tous les athletes ayant participe au marathon de New-York, dans les categories WC et HC, ont ete analyses entre 1999 et 2010. Durant cette periode, un total de 698 athletes WC (132 femmes et 566 hommes) et 776 athletes HC (141 femmes et 635 hommes) ont termine la course. Les femmes representaient 20 % du total des arrivants dans les deux categories. Les athletes en categorie WC etait significativement (P < 0,01) plus jeunes en comparaison de…

Swimming performances in long distance open-water events with and without wetsuit.
2013
International audience; BACKGROUND: Existing literature showed improved swimming performances for swimmers wearing wetsuits competing under standardized conditions in races held in pools on short to middle distances. Data about the influence of wetsuits on swimming performances in long and ultra-long open-water swimming races are missing. It is unknown whether the benefit of wearing wetsuits is comparable in men and women. The aim of this study was to investigate the influence of wearing a wetsuit on open-water swimming performances at the 26.4 km 'Marathon Swim in Lake Zurich' in Lake Zurich, Switzerland, and the 3.8 km Lake Ontario Swim Team-Race (LOST-Race) in Lake Ontario, Canada.
