Race Strategies of Open Water Swimmers in the 5-km, 10-km, and 25-km Races of the 2017 FINA World Swimming Championships

Frontiers in Psychology, 2019
Despite literature on the pacing strategies of endurance sports, there is an existing lack of knowledge about the swimmers’ tactical decisions in the open water races.

Reynolds number limits for jet propulsion: A numerical study of simplified jellyfish [PDF]

, 2010
The Scallop Theorem states that reciprocal methods of locomotion, such as jet propulsion or paddling, will not work in Stokes flow (Reynolds number = 0).

Determining Validity and Reliability of an In-Field Performance Analysis System for Swimming

Sensors
To permit the collection of quantitative data on start, turn and clean swimming performances in any swimming pool, the aims of the present study were to (1) validate a mobile in-field performance analysis system (PAS) against the Kistler starting block ...

Correlations between linear sprint with the ball, linear sprint without the ball, and change-of-direction without the ball in professional female soccer players

Scientific Reports, 2023
The evolution of female soccer is related to the increase in high-intensity actions and choosing the abilities that best characterize the players' performance. Determining the capabilities that best describe the players' performance becomes essential for

Focusing of Active Particles in a Converging Flow

, 2017
We consider active particles swimming in a convergent fluid flow in a trapezoid nozzle with no-slip walls. We use mathematical modeling to analyze trajectories of these particles inside the nozzle.

The Least Squares Method as a Tool for Assessment of the Stroke Parameters and Velocity in Monofin Swimming

Methods and Protocols
This study explores the application of the Least Squares Method to analyze and model the kinematic parameters in monofin swimming, focusing on stroke rate, stroke length, and the amplitudes of joint displacements at the hip, knee, and ankle.

Unsteady feeding and optimal strokes of model ciliates

, 2012
The flow field created by swimming microorganisms not only enables their locomotion but also leads to advective transport of nutrients. In this paper we address analytically and computationally the link between unsteady feeding and unsteady swimming on a

Flagellar propulsion [PDF]

, 2006
In this JEB Classics paper, Sir James Gray and G. J. Hancock explained how spermatozoa are propelled by flagellar bending waves (Gray and Hancock, 1955). This paper was a lasting success because it provided an easy-to-understand solution to a complicated

Lifestyle Behaviors and Cardiotoxic Treatment Risks in Adult Childhood Cancer Survivors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Higher doses of anthracyclines and heart‐relevant radiotherapy increase cardiovascular disease (CVD) risk. This study assessed CVD and CVD risk factors among adult childhood cancer survivors (CCSs) across cardiotoxic treatment risk groups and examined associations between lifestyle behaviors and treatment risks.

Quantity of within-sport distance variety – what can pool swimmers and track runners learn from each other?

Frontiers in Sports and Active Living
ObjectiveTo determine the relationship between success at peak performance age and quantity of within-sport distance variety and compare the dose-time-effect between swimming and track running by determining probability of becoming an international-class
