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 wo...

The purpose of this study was to investigate the effect of foot movement on the instantaneous COM velocity changing during kick movement for elite female breaststroke swimmers. Nine elite swimmers swam at their maximal effort in a 25-m pool. The swimming motions were recorded with the motion capture system. The COM velocity generated by kick movement was not related the foot velocity. In contra...

ABSTRACT Introduction: It is believed that strengthening cardiopulmonary function can reduce health risks caused by the COVID-19 virus, and swimming a practice could benefit its practitioners during epidemic context. Objective: Study effect of on capacity college students in context COVID-19. Methods: A total 60 volunteers three groups were trained twice week for one hour each 12 weeks. Among t...

OBJECTIVE: In this study, we compare muscular strength of the internal rotators and adductors of the shoulder between asymmetrical (backstroke and freestyle) and symmetrical (breaststroke and butterfly) swimming strokes. METHOD: We evaluated: shoulders of (a) asymmetrical swimmers (aged 21.8 ^ 3.8 years), (b) symmetrical swimmers (aged 20.3 ^ 4.5 years), (c) recreational swimmers (aged 24.5 ^ 4...

Despite increased interest in ultra-endurance events, little research has examined ultra-triathlon performance. The aims of this study were: (i) to compare swimming, cycling, running, and overall performances in three ultra-distance triathlons, double Ironman distance triathlon (2IMT) (7.6 km swimming, 360 km cycling, and 84.4 km running), triple Ironman distance triathlon (3IMT) (11.4 km, 540 ...

The change in swim performance over time has been investigated for freestyle, but not for other strokes, such as in the medley. The aim of the study was to examine changes in 200 m and 400 m swim performances in medley swimmers at national (Switzerland) and international level (world championship finals) from 1994 to 2011. The 200 m and 400 m freestyle performances were also analyzed for compar...

The paper employs traditional sports research methodologies involving document reference, interview, pedagogical observation, and testing. Based on theoretical, practical, pedagogical, scientific principles, the authors construct an extra-curricular program in swimming drowning prevention skills for students grades 6 7 Bac Lieu City, province. is designed to provide with ability identify danger...

The purpose of this paper was to examine the characteristics of waves generated when swimming with and without the use of Aquatrainer® snorkels. Eight male swimmers performed two maximal bouts of 25 m breaststroke, first without the use of a snorkel (normal condition) and then using a snorkel (snorkel condition). The body landmarks, centre of the mass velocity, stroke rate, stroke length, strok...
