Key somatic variables in young backstroke swimmers [PDF]

Journal of Sports Sciences, 2018
The purpose of this study was to estimate the optimal body size, limb-segment length, girth or breadth ratios for 100-m backstroke mean speed performance in young swimmers. Sixty-three young swimmers (boys [n = 30; age: 13.98 ± 0.58 years]; girls [n = 33; age: 13.02 ± 1.20 years]) participated in this study.

Bilateral anterior dislocation of the shoulders at the start of a backstroke competition [PDF]

Journal of Orthopaedics and Traumatology, 2012
Bilateral anterior dislocation of the shoulders is very rare. A 20-year-old man presented with bilateral anterior shoulder dislocation as a result of a diving incident. He complained of pain and restriction of movement in both shoulders with abducted and externally rotated arms. Radiographs revealed that the shoulders were dislocated.

Body roll amplitude and timing in backstroke swimming and their differences from front crawl at the same swimming intensities

Scientific Reports, 2021
The current study investigated body roll amplitude and timing of its peak in backstroke and compared them with front crawl swimming. Nineteen anatomical landmarks were digitised using 80 swimming trial videos (ten swimmers × two techniques × four ...

Biomechanical Characteristics of Double-Arm Backstroke—A Specialist Freestyle Technique Employed by Severely Impaired Para Swimmers

Applied Sciences
This exploratory study compares the Froude efficiency (ηF), intra-cyclic speed fluctuation (ICSF) and other performance determinants between two freestyle swimming techniques: double-arm backstroke and front crawl, and then demonstrates how Para swimmers

A Biomechanical Analysis into Backstroke Start Kinematics: The Influence of a Backstroke Start Device.

, 2019
Background: Backstroke starts have received little scientific attention; this may be due to the ongoing modifications to rules but also the fact that the majority of swim starts occur from a dive. As such, this has been the focus for much swim start research.

The Relationship Between Vision and Performance in Swimming Under Simulated Vision Impairment: Establishing an Empirically Driven Minimum Impairment Criteria for Para Swimming

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 7, July 2026.
ABSTRACT Paralympic sport provides tremendous opportunities for individuals with impairment, including vision impairment, but there is controversy about the fairness of competition. Particularly, it remains unclear how much impairment should be necessary to compete.

Comparison of classical kinematics, entropy and fractal properties as measures of complexity of the motor system in swimming

Frontiers in Psychology, 2016
The aim of this study was to compare the nonlinear properties of the four competitive swim strokes. Sixty-eight swimmers performed a set of maximal 4x25m using the four competitive swim strokes.

New partial skeleton of Homo habilis from the upper Burgi Member, Koobi Fora Formation, Ileret, Kenya

The Anatomical Record, Volume 309, Issue 3, Page 485-545, March 2026.
Abstract KNM‐ER 64061 is a partial skeleton from the upper Burgi Member of the Koobi Fora Formation (2.02–2.06 Ma) associated taphonomically and geochemically with a nearly complete mandibular dentition (KNM‐ER 64060) attributed to Homo habilis.
