50 m freestyle in 21, 22 and 23 s: What differentiates the speed curve of world-class and elite male swimmers?
(Peer reviewed; Journal article, 2021)We examined the association between 50 m freestyle performance (50FS) and average speed (AS), peak speed (PS), minimum speed (MS) and intracyclic speed variation (ISV) and compared the speed curves from swimmers with ... -
Added mass in human swimmers: age and gender differences
(Journal article; Peer reviewed, 2010-05-23)In unstationary swimming (changing velocity), some of the water around the swimmer is set in motion. This can be thought of as an added mass (Ma) of water. The purpose of this study was to find added mass on human swimmers ... -
Arm–leg coordination during the underwater pull-out sequence in the 50, 100 and 200 m breaststroke start
(Peer reviewed; Journal article, 2022)Objectives: To investigate the arm–leg coordination from different perspectives of motor control during the underwater start sequence to understand whether differences exist between the three competitive breaststroke ... -
Arm–Leg coordination profiling during the dolphin kick and the arm pull-out in elite breaststrokers
(Peer reviewed; Journal article, 2021)In breaststroke races, the dolphin kick could finish before, at the same time, or during the arm pull-out, but it is unclear how swimmers perform this technique. The aim of this study was to investigate whether swimmers ... -
Breaststroke swimmers moderate internal work increases toward the highest stroke frequencies
(Journal article; Peer reviewed, 2015-09-18)A model to predict the mechanical internal work of breaststroke swimming was designed. It allowed us to explore the frequency–internal work relationship in aquatic locomotion. Its accuracy was checked against internal work ... -
Can you swim?: an exploration of measuring real and perceived water competency
(Journal article; Peer reviewed, 2012)Little is known about the relationship between real and perceived water competence among youth in the context of drowning prevention or of their perceptions of their risk of drowning. This study reports the findings of ... -
Core temperature in triathletes during swimming with wetsuit in 10 °C cold water
(Peer reviewed; Journal article, 2019)Low water temperature (<15 °C) has been faced by many organizers of triathlons and swim-runs in the northern part of Europe during recent years. More knowledge about how cold water affects athletes swimming in wetsuits in ... -
Differences between elite and sub-elite swimmers in a 100 m breaststroke: A new race analysis approach with time-series velocity data
(Peer reviewed; Journal article, 2021)The purpose of the present study was to investigate differences in a 100 m breaststroke time-trial between elite and sub-elite swimmers. Elite and sub-elite male swimmers (seven each; 772.1 ± 35.2 and 610.6 ± 24.7 FINA ... -
Differences in race characteristics between world-class individual-medley and stroke-specialist swimmers
(Peer reviewed; Journal article, 2022)The purpose of the present study was to investigate differences between world-class individual medley (IM) swimmers and stroke-specialists using race analyses. A total of eighty 200 m races (8 finalists × 2 sexes × 5 events) ... -
Disordered eating and eating disorders in aquatic sports
(Journal article; Peer reviewed, 2014-08)Disordered eating behavior (DE) and eating disorders (EDs) are of great concern because of their associa- tions with physical and mental health risks and, in the case of athletes, impaired performance. The syndrome originally ... -
The effect of experience in movement coordination with music on polyrhythmic production: Comparison between artistic swimmers and water polo players during eggbeater kick performance
(Peer reviewed; Journal article, 2020)The aim of this study was to compare artistic swimmers (ASs) and water polo players (WPs) in their polyrhythmic production ability and entrainment between arm and leg motion frequency. Nine ASs and nine WPs participated ... -
Effects of antioxidant-rich foods on altitude-induced oxidative stress and inflammation in elite endurance athletes: A randomized controlled trial
(Peer reviewed; Journal article, 2019)Background: Various altitude training regimes, systematically used to improve oxygen carrying capacity and sports performance, have been associated with increased oxidative stress and inflammation. We investigated whether ... -
Front crawl body roll characteristics in a Paralympic medallist and national level swimmers with unilateral arm amputation
(Peer reviewed; Journal article, 2019)The purpose of this study was to establish the asymmetry and body wave characteristics related to shoulder, hip, knee, and ankle roll in unilateral arm amputee swimmers. Three unilateral arm amputee swimmers, including one ... -
The gold rush in para swimming: changes in the speed curve of a visually impaired world and paralympic champion–a case study
(Peer reviewed; Journal article, 2023)This case study examined the association between 50 m freestyle and speed curve parameters of a world-class Paralympic swimmer and analysed the changes in speed curves and their frequency components across her performance ... -
High intensity interval training improves VO2peak, maximal lactate production, time trial and competition performance in 9-11 year old swimmers
(Journal article; Peer reviewed, 2010-08-04)Training volume in swimming is usually very high when compared to the relatively short competition time. High-intensity interval training (HIIT) has been demonstrated to improve performance in a relatively short training ... -
Intra- and inter-individual variability in the underwater pull-out technique in 200 m breaststroke turns
(Peer reviewed; Journal article, 2023)The purpose of the present study was to investigate the intra- and inter-individual variability in arm-leg coordination during the underwater phase of the turn segment in 200 m breaststroke. Thirteen male swimmers were ... -
