Body roll amplitude and timing in backstroke swimming and their differences from front crawl at the same swimming intensities
Gonjo, Tomohiro; Fernandes, Ricardo J.; Vilas-Boas, João Paulo; Sanders, Ross (Peer reviewed; Journal article, 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 ... -
Differences in the rotational effect of buoyancy and trunk kinematics between front crawl and backstroke swimming
Gonjo, Tomohiro; Fernandes, Ricardo J.; Vilas-Boas, J. Paulo; Sanders, Ross (Peer reviewed; Journal article, 2021)The purpose of the present study is to investigate differences between front crawl and backstroke swimming in hydrodynamic (produced by swimmers) and buoyant torque around the transverse axis. Ten swimmers performed 50 m ... -
Front crawl body roll characteristics in a Paralympic medallist and national level swimmers with unilateral arm amputation
Gonjo, Tomohiro; Kishimoto, Taichi; Sanders, Ross; Saito, Mayumi; Takagi, Hideki (Peer reviewed; Journal article, 2019)The purpose of this study was to establish the asymmetry and body wave characteristics related to shoulder, hip, knee, and ankle roll in unilateral arm amputee swimmers. Three unilateral arm amputee swimmers, including one ... -
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
Gonjo, Tomohiro; Narita, Kenzo; McCabe, Carla; Fernandes, Ricardo J.; Vilas-Boas, João Paulo; Takagi, Hideki; Sanders, Ross (Peer reviewed; Journal article, 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 ... -
How do swimmers control their front crawl swimming velocity?: Current knowledge and gaps from hydrodynamic perspectives
Takagi, Hideki; Nakashima, Motomu; Sengoku, Yasuo; Tsunokawa, Takaaki; Koga, Daiki; Narita, Kenzo; Kudo, Shigetada; Sanders, Ross; Gonjo, Tomohiro (Peer reviewed; Journal article, 2021)The aim of this study was to review the literature on front crawl swimming biomechanics, focusing on propulsive and resistive forces at different swimming velocities. Recent studies show that the resistive force increases ... -
Upper body kinematic differences between maximum front crawl and backstroke swimming
Gonjo, Tomohiro; Fernandes, Ricardo J.; Vilas-Boas, João-Paulo; Sanders, Ross (Peer reviewed; Journal article, 2020)The purpose of this study was to investigate why front crawl is faster than backstroke from a kinematic perspective. Three-dimensional kinematics were obtained from one upper-limb cycle of ten male competitive swimmers ...
