Multiple modulation torque planning for a new golf-swing robot with a skilful wrist turn
Springer Science and Business Media LLC - Tập 9 Số 4 - Trang 201-208 - 2006
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
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...
Differences in soccer kicking type identified using principal component analysis
Springer Science and Business Media LLC - Tập 21 - Trang 149-159 - 2017
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...
Video analysis of head injury incidents in equestrian sports
Springer Science and Business Media LLC - Tập 23 - Trang 1-9 - 2020
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...
Abstracts from the 5th International Conference on the Engineering of Sport, 13–16 September 2004, University of California, Davis, California, USA
Springer Science and Business Media LLC - Tập 7 - Trang 197-226 - 2004
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
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...
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
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....
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
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...
Wireless instrumented klapskates for long-track speed skating
Springer Science and Business Media LLC - Tập 19 - Trang 273-281 - 2016
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...
