Front Crawl Is More Efficient and Has Smaller Active Drag Than Backstroke Swimming: Kinematic and Kinetic Comparison Between the Two Techniques at the Same Swimming Speeds

Frontiers in Bioengineering and Biotechnology, 2020
The purpose of this study was to investigate differences in Froude efficiency (ηF) and active drag (DA) between front crawl and backstroke at the same speed. ηF was investigated by the three-dimensional (3D) motion analysis using 10 male swimmers.

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.

Different Lower-Limb Setup Positions Do Not Consistently Change Backstroke Start Time to 10 m

Sports, 2020
Backstroke starts involve the athlete starting from a flexed position with their feet against the pool wall and then extending their ankles, knees, hips and back to push off; however, swimmers can start in different positions.

Backstroke start performance: the impact of using the Omega OBL2 backstroke ledge

Sports Biomechanics, 2017
FINA recently approved the backstroke ledge (Omega OBL2) to improve backstroke start performance in competition, but its performance has not been thoroughly evaluated. The purpose of this study was to compare the mechanics of starts performed with and without the OBL2.

The Backstroke Swimming Start: State of the Art [PDF]

Journal of Human Kinetics, 2014
Abstract As sprint swimming events can be decided by margins as small as .01 s, thus, an effective start is essential. This study reviews and discusses the ‘state of the art’ literature regarding backstroke start biomechanics from 23 documents.

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 ...

EVALUATION OF MISTAKES IN BACKSTROKE SWIMMING

Kinesiologia Slovenica, 2020
Purpose. We tried to determine the perceptions of experienced swimming teachers and coaches (hereinafter “experts”) regarding common mistakes in backstroke swimming. Moreover, we compared their evaluation with the evaluation of participants with no professional expertise in teaching/coaching swimming (hereinafter »non-experts«). Methods.

Golden ratio and self-similarity in swimming: breast-stroke and the back-stroke

Frontiers in Human Neuroscience, 2023
IntroductionDynamics-on-graph concepts and generalized finite-length Fibonacci sequences have been used to characterize, from a temporal point of view, both human walking & running at a comfortable speed and front-crawl & butterfly swimming ...
