Abstract

In recent years, physiological investigations suggested that a kayak seat able to rotate in the horizontal plane (swivel seat) may improve performance, but kinematic data are limited. The aim of this study was to investigate the effect of the swivel seat on kinematics and performance during sprint paddling on an ergometer. Nine experienced kayakers volunteered for this study and each completed two maximal trials of 30 s on the ergometer, one with the swivel seat and the other with a fixed seat. Three-dimensional motion analysis and performance data were collected at 200 Hz during the central 10 s of each trial. The use of the swivel seat was observed to improve performance through a significant increase in peak fly-wheel RPM (p = 0.033) and paddle antero-posterior displacement (p = 0.015) and a significant decrease in right side paddle recovery time (p = 0.043). In conclusion, the use of the swivel seat was associated with kinematic changes that improved performance and decreased the risk of excessive spine rotation. These results offer new insights into understanding the implications of swivel seat use for the dynamics of kayaking.

期刊介绍： Sports Biomechanics is the Thomson Reuters listed scientific journal of the International Society of Biomechanics in Sports (ISBS). The journal sets out to generate knowledge to improve human performance and reduce the incidence of injury, and to communicate this knowledge to scientists, coaches, clinicians, teachers, and participants. The target performance realms include not only the conventional areas of sports and exercise, but also fundamental motor skills and other highly specialized human movements such as dance (both sport and artistic). Sports Biomechanics is unique in its emphasis on a broad biomechanical spectrum of human performance including, but not limited to, technique, skill acquisition, training, strength and conditioning, exercise, coaching, teaching, equipment, modeling and simulation, measurement, and injury prevention and rehabilitation. As well as maintaining scientific rigour, there is a strong editorial emphasis on ''reader friendliness''. By emphasising the practical implications and applications of research, the journal seeks to benefit practitioners directly. Sports Biomechanics publishes papers in four sections: Original Research, Reviews, Teaching, and Methods and Theoretical Perspectives.
