Introduction: The age of peak freestyle swimming speed was reported to be at ~17 years for women and ~19 years for men. However, the age of peak swimming speed for other strokes such as butterfly is not known. Objectives: We investigated whether the age of peak swimming speed and peak swimming speed changed across years in elite butterfly and freestyle swimmers at national level (Switzerland) b...

BACKGROUND Sex-related differences in performance and in age of peak performance have been reported for freestyle swimming. However, little is known about the sex-related differences in other swimming styles. The aim of the present study was to compare performance and age of peak performance for elite men and women swimmers in breaststroke versus freestyle. METHODS Race results were analyzed ...

The swimming abilities of fishes are of vital importance to their ecology, and studies on fish swimming have been the focus of research for over a century. Here we explore the relationship between swimming ability and external body morphology, using data on U(crit) swimming speeds of 100 species of pre-settlement juvenile coral reef fishes (at the transition between the larval and adult habitat...

The main focus of swimming in the first half of the nineteenth century was simply for enjoyment and pleasure, plus its endorsement by society as a wholesome rational recreation. It was pursued at popular river sites, at the seaside, at private baths clubs or at the newly emerging municipal baths. The formation of swimming clubs, during the middle years of the century, was the beginning of a cha...

This study was carried out in the summer of 2005 and investigated all of active public swimming pools (85 out of 93) in Amman, the capital of Jordan. The aim of this study was to find out if these swimming pools are in compliance with Jordanian Standards for Swimming Pools Water (JS 1562/2004). The pools were surveyed against the water microbial quality and other physicochemical parameters indi...

Motivated by our desire to understand the biophysical mechanisms underlying the swimming of sperm in the non-Newtonian fluids of the female mammalian reproductive tract, we examine the swimming of filaments in the nonlinear viscoelastic upper convected Maxwell model. We obtain the swimming velocity and hydrodynamic force exerted on an infinitely long cylinder with prescribed beating pattern. We...

Studies of locomotor performance have contributed to the elucidation of how suborganismal traits ultimately relate to fitness. In terrestrial populations, exploring the physiological and environmental contributions to whole-animal performance measures has improved our understanding of phenotypic selection. Conversely, very little is known about the links between phenotypic selection and swimmin...

This article analyses a game where players sequentially choose either to become insiders and pick one of fi nitely many locations or to remain outsiders. They will only become insiders if a minimum distance to the next player can be assured; their secondary objective is to maximise the minimal distance to other players. This is illustrated by considering the strategic behaviour of men choosing ...

This study was conducted to investigate the effects of the degree of participation in swimming lessons and the participation styles on health perception and belief. To do this, several analyses were conducted-statistical analysis, frequency analysis, factorial analysis, reliability analysis, correlation analysis, and regression analysis-using SPSS 18.0. A total of 300 copies of the questionnair...

The energetics and behavior of the parapodial-swimming Aplysia brasiliana were investigated in order to compare net cost of transport (COTnet) between swimming and crawling, and to compare transport costs with other swimmers. Oxygen consumption (VO2) increased with increasing animal mass for resting, crawling, and swimming animals. Slopes of the regressions of log VO2 on log mass were 0.90, 0.9...
