The Effect Of Movement Variability On Putting Proficiency During The Golf Putting Stroke, Ashley K. Richardson, Andrew C.S. Mitchell, Gerwyn Hughes
The Effect Of Movement Variability On Putting Proficiency During The Golf Putting Stroke, Ashley K. Richardson, Andrew C.S. Mitchell, Gerwyn Hughes
Kinesiology (Formerly Exercise and Sport Science)
Movement variability has been considered important to execute golf swing yet is comparatively unexplored regarding the golf putt. Movement variability could potentially be important considering the small margins of error between successful and a missed putt. The aim of this study was to assess whether variability of body segment rotations influence putting performance (ball kinematic measures). Eight golfers (handicap range 0-10) performed a 3.2 metre level putt wearing retro-reflective markers which were tracked using a three-dimensional motion analysis system sampling at 120 Hz. Ball roll kinematics were recorded using Quintic Ball Roll launch monitor. Movement (segment) variability was calculated based …
The Effect Of Dimple Error On The Horizontal Launch Angle And Side Spin Of The Golf Ball During Putting, Ashley K. Richardson, Andrew C.S. Mitchell, Gerwyn Hughes
The Effect Of Dimple Error On The Horizontal Launch Angle And Side Spin Of The Golf Ball During Putting, Ashley K. Richardson, Andrew C.S. Mitchell, Gerwyn Hughes
Kinesiology (Formerly Exercise and Sport Science)
This study aimed to examine the effect of the impact point on the golf ball on the horizontal launch angle and side spin during putting with a mechanical putting arm and human participants. Putts of 3.2 m were completed with a mechanical putting arm (four putter-ball combinations, total of 160 trials). The centre of the dimple pattern (centroid) was located and the following variables were measured; distance and angle of the impact point from the centroid and surface area of the impact zone. Multiple regression analysis was conducted to identify whether impact variables had significant associations with ball roll variables; …
The Effect Of Arm Position On Lower Extremity Kinematics During A Single Limb Drop Landing: A Preliminary Study, C. Masters, J. Johnstone, Gerwyn Hughes
The Effect Of Arm Position On Lower Extremity Kinematics During A Single Limb Drop Landing: A Preliminary Study, C. Masters, J. Johnstone, Gerwyn Hughes
Kinesiology (Formerly Exercise and Sport Science)
Anterior cruciate ligament (ACL) injuries occur most commonly during non-contact situations, such as landing from a jump. Arm position has been shown to affect the loading of the lower extremity and therefore alter the potential injury risk. This study aimed to investigate the effect of arm position on lower extremity kinematics during single limb drop landings. Eight recreational American football players performed single limb drop landings on their preferential limb in four different conditions; (1) control (arms free); (2) arms to landing limb side; (3) arms in front of body; and (4) arms away from landing limb side. Kinematics of …
Gender Differences In Lower Limb Frontal Plane Kinematics During Landing, Gerwyn Hughes, James Watkins, Nick Owen
Gender Differences In Lower Limb Frontal Plane Kinematics During Landing, Gerwyn Hughes, James Watkins, Nick Owen
Kinesiology (Formerly Exercise and Sport Science)
The study aimed to investigate gender differences in knee valgus angle and interknee and inter-ankle distances in university volleyball players when performing opposed block jump landings. Six female and six male university volleyball players performed three dynamic trials each where subjects were instructed to jump up and block a volleyball suspended above a net set at the height of a standard volleyball net as it was spiked against them by an opposing player. Knee valgus/varus, interknee distance and inter-ankle distance (absolute and relative to height) were determined during landing using 3D motion analysis. Females displayed significantly greater maximum valgus angle …
