Inter rater reliability of practical assessment criteria for aquatic literacy in children
Absence of Sex Difference in Digit Ratio ( 2D
The swimmers had lower 2D:4D than non-sporting individuals; the top level swimmers had the lowest 2D:4D. The female swimmers, particularly the elite group, showed "masculine" 2D:4D similar to their male counterparts. A plausible positive selection for a masculinised digit ratio (higher prenatal testosterone exposure) among the females in highly competitive professional sports was hypothesized
Identification of key somatic features that are common and the ones that differ between swim strokes through allometric modeling
Introduction The aim of this study was to explore which key somatic features are common to four swim strokes and medley, and specifically to identify which characteristics benefit only specific strokes. Methods The sample was composed of 130 swimmers (95 males aged 19.5 ± 2.9 years and 35 females aged 18.4 ± 2.8 years). A set of anthropometric variables was used to predict swimming speed in the four swimming strokes and medley. Results A multipli…
Does the Back Plate Position Influence Swimming Start Temporal Characteristics
The current study examined the back plate position impact on the block phase movement pattern and total starting performance with a distinction for sex. Thirty-eight swimmers performed starts changing the back plate position (preferred position, one position forward and one position backward), with the data being assessed using a 3D dynamometric central and a video camera. In males, the 15 m start time was 0.1 s shorter for the preferred position…
Perceived Versus Real Swimming Skills of Adolescents under Standard and Challenging Conditions
In this study, we compared adolescents' actual (expert assessed) front crawl swimming skills to their self-assessment in two conditions: in standard swimming (wearing a swimsuit and goggles) and in a simulated risk scenario (swimming in plain clothes without goggles). We postulated that education focused on water competencies is fundamental in preventing drownings. Experts evaluated the skills of 21 female and 21 male adolescents in both standard…
Adaptation to Speed Distortions Under Water
A diver's face‐mask normally makes close objects in clear water appear both enlarged and too near. Objects travelling across the line of sight therefore appear to move faster than in air, and objects moving along the line of sight slower. Subjects estimated the speed of a moving rod in air and water, before and after a 10 min. period spent swimming and playing a pegboard game under water. Twenty subjects were tested with the rod moving across, an…
