Purpose: To assess the effects of omega 3 fatty acid supplementation to swimmers on biochemical indicators. Methods: Male elite swimmers (n = 14) were assessed in a placebo-controlled randomized study over a 6-week (45-day) experimental period. The placebo group (GP) received mineral oil (n = 6) and the supplemented group (GOP) received fish oil (n = 8) containing a total of 950 mg of eicosapen...

BACKGROUND Endurance swimming exercises coupled to disinfection by-products exposure has been associated with increased airways dysfunction and neurogenic inflammation in elite swimmers. However, the impact of swimming pool exposure at a recreational level on autonomic activity has never been explored. Therefore, this study aimed to investigate how swimming pool attendance is influencing lung a...

The purpose was to observe the effects of a four-week lockdown on resting heart rate (RHR) and well-being perception elite swimmers. Twenty swimmers performed RHR measurements upon waking in supine standing positions. Baseline values those measured after four weeks were compared. Swimmers completed questionnaire their training volume state well-being. During lockdown, reported weekly mean physi...

Vliv relativního věku (RAE) je fenomén, který silně ovlivňuje sportovní vývoj mládeže. RAE odkazuje na neúměrně vysoké procento sportovců narozených začátku kalendářního (selekčního) roku. Řada studií, zejména v kolektivních sportech, tuto skutečnost prokázala. V individuálních jako například plavání, však stále chybí dostatečný počet což znemožňuje k...

Performance trends in breaststroke swimmers competing at world class level in pool competitions are well investigated for elite swimmers, but not for age group swimmers. This study investigated trends in participation, performance and sex difference in performance in a total of 35,143 (16,160 women and 18,983 men) age group breaststroke swimmers aged 25-29 to 95-99 years competing in the Fédéra...

BACKGROUND The age of peak swim performance has been investigated for freestyle swimmers for distances ranging from 50 m to 1500 m among swimmers aged 19 to 99 years. However, studies have yet to investigate the 10 to 19 year-old age group. The aims of the present study were (1) to investigate the age range of peak freestyle swim speed, and (2) to find differences in age range and peak freestyl...
