Effects of exceeding stroke frequency of maximal effort on hand kinematics and hand propulsive force in front crawl
Koga, Daiki; Gonjo, Tomohiro; Kawai, Eisuke; Tsunokawa, Takaaki; Sakai, Shin; Sengoku, Yasuo; Homma, Miwako; Takagi, Hideki (Peer reviewed; Journal article, 2020)This study aimed to assess kinematic and kinetic changes in front crawl with various stroke frequency (SF) conditions to investigate why swimming velocity (SV) does not increase above a certain SF (SFmax). Eight male ... -
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 ...
