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 ... -
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 ...
