Validity and reliability of impact forces from a commercially instrumented water-filled punching bag
Springer Science and Business Media LLC - Tập 25 - Trang 1-5 - 2022
Shelley N. Diewald, Matt R. Cross, Jono Neville, John B. Cronin
Measuring striking forces is important to provide actionable insight for training and performance enhancement for combat sport athletes. Recent technology may provide a low-cost solution to an otherwise complicated kinetic assessment. The aim was to assess the reliability and validity of a water-filled training bag and integrated sensor for measuring peak impact force. A pendulum design was used t...... hiện toàn bộ
Differences in soccer kicking type identified using principal component analysis
Springer Science and Business Media LLC - Tập 21 - Trang 149-159 - 2017
Taishu Nakamura, Tasuku Miyoshi, Shota Sato, Motoki Takagi, Yasuhisa Kamada, Yoshiyuki Kobayashi
Soccer kicks are characterized by segmental and joint rotations in multiple planes, where large discrepancies between two- and three-dimensional analyses for angular measurements of soccer kicks exist. The aim of this study was to clarify the differences in motions of the lower limbs and the pelvis required to achieve a shot without rotations as compared with an instep kick. Kinematic parameters o...... hiện toàn bộ
Video analysis of head injury incidents in equestrian sports

Current helmet certification tests involve linear impacts on rigid anvils. The associated kinematics by which a jockey falls from a horse while riding are believed to be fundamentally different to those in the certification tests, i.e., they involve oblique falls (falls at an angle) to compliant surfaces. This paper provides primary data from real-world equestrian accidents to characterise such ki...... hiện toàn bộ
Abstracts from the 5th International Conference on the Engineering of Sport, 13–16 September 2004, University of California, Davis, California, USA

Golfers do not respond to changes in shaft mass properties in a mechanically predictable way
Springer Science and Business Media LLC - Tập 15 - Trang 215-220 - 2012
Daniel F. B. Haeufle, Jay Worobets, Ian Wright, Jenny Haeufle, Darren Stefanyshyn
A common belief in the golf community is that a lighter shaft allows the golfer to swing the club faster. From a mechanical point of view, reducing the mass of the shaft would result in a faster swing. However, a golfer is not a purely mechanical system, and so it is simplistic to assume that identical loads will be applied when swinging different clubs. Therefore, the purpose of this study was to...... hiện toàn bộ

Validation of a multi-camera videogrammetry approach for quantifying helmet impact velocity in football
Springer Science and Business Media LLC - Tập 26 - Trang 1-8 - 2023
Danielle L. Gyemi, Ron Jadischke, David M. Andrews
This study presents the validation of a multi-camera videogrammetry approach for measuring football helmet impact velocities, wherein the effect of camera angle, camera distance and impact speed were assessed. Helmet-to-ground impacts were simulated within two zones on a field using free fall drop tests of a helmeted head and neck assembly at heights of 1.04 m (slow: 4.52 m/s) and 1.83 m (fast: 5....... hiện toàn bộ
The influence of gravimetric moisture content on studded shoe–surface interactions in soccer
Springer Science and Business Media LLC - Tập 20 - Trang 121-132 - 2016
James Clarke, Matt J. Carré
It is desirable for the studs of a soccer shoe to penetrate the sport surface and provide the player with sufficient traction when accelerating. Mechanical tests are often used to measure the traction of shoe–surface combinations. Mechanical testing offers a repeatable measure of shoe–surface traction, eliminating the inherent uncertainties that exist when human participant testing is employed, an...... hiện toàn bộ
Wireless instrumented klapskates for long-track speed skating
Springer Science and Business Media LLC - Tập 19 - Trang 273-281 - 2016
E. van der Kruk, O. den Braver, A. L. Schwab, F. C. T. van der Helm, H. E. J. Veeger
In the current project, we aim to provide speed skaters with real-time feedback on how to improve their skating performance within an individual stroke. The elite skaters and their coaches wish for a system that determines the mechanical power per stroke. The push-off force of the skater is a crucial variable in this power determination. In this study, we present the construction and calibration o...... hiện toàn bộ
