Upper Limb Kinematics During the Topspin Double-Handed Backhand Stroke in Tennis
38th International Society of Biomechanics in Sport Conference, Physical conference cancelled, Online Activities: July 20-24, 2020 UPPER LIMB KINEMATICS DURING THE TOPSPIN DOUBLE-HANDED BACKHAND STROKE IN TENNIS Nicholas A. Busuttil1, Machar Reid2, Molly Connolly2,3, Ben J. Dascombe4 & Kane J. Middleton1 Sport and Exercise Science, School of Allied Health, Human Services, and Sport, La Trobe University, Melbourne, Australia1 Game Insight Group, Tennis Australia, Melbourne, Australia2 Institute for Health and Sport, Victoria University, Melbourne, Australia3 Applied Sport Science and Exercise Testing Laboratory, School of Life and Environmental Sciences, University of Newcastle, Ourimbah, Australia4 The purpose of this study was to compare non-dominant wrist kinematics during tennis double-handed backhand strokes in players using either an eastern or continental grip position. Trajectory data for two grips (eastern & continental) and depths (deep & short) were captured for sixteen sub-elite right-handed tennis players using a 12-camera Vicon motion capture system (250 Hz). The eastern grip demonstrated significantly faster horizontal racket head velocities compared to the continental grip. However, no differences were observed in accuracy or spin rate between grips (p > 0.05). In the non-dominant upper limb for the continental condition, elbow flexion was smaller while wrist extension was larger throughout the swing. Collectively, these data suggest that the continental grip may place the wrist in a position that is more vulnerable to overuse injury. KEYWORDS: ulna, wrist, kinematics, grip, tennis. INTRODUCTION: Acute wrist pain is among the most common issues reported by elite and recreational tennis players, and it is a likely result of the wrist being the first major upper limb joint to absorb ball impact forces (Stuelcken, Mellifont, Gorman, & Sayers, 2017; Elliott, 2006). -

Nadal is in his seventh consecutive Grand Slam semi-final, eighth overall at the US Open and 33rd in his career, while Dimitrov is playing in his third Grand Slam semi-final. Medvedev and Berrettini are making their Grand Slam semi-final debuts. Medvedev and Berrettini are both 23 years old. This is the first Grand Slam tournament semi-final with two players 23 (or younger) since last year’s Australian Open with Hyeon Chung (21) and Kyle Edmund (23). The last US Open SFs with two players 23 (or younger) was Juan Martin del Potro (20) and Novak Djokovic (22) in 2009. This is also the first Grand Slam semi-final with three players born in the 1990s: Medvedev (1996), Berrettini (1996) and Dimitrov (1991). One of the three is looking to become the first Grand Slam champion born in the 1990s. There have been two finalists: Dominic Thiem at Roland Garros in 2018-19 and Milos Raonic at Wimbledon in 2016. -

Measurements of the Horizontal Coefficient of Restitution for a Superball and a Tennis Ball
Measurements of the horizontal coefficient of restitution for a superball and a tennis ball Rod Crossa) Physics Department, University of Sydney, Sydney, NSW 2006 Australia ͑Received 9 July 2001; accepted 20 December 2001͒ When a ball is incident obliquely on a flat surface, the rebound spin, speed, and angle generally differ from the corresponding incident values. Measurements of all three quantities were made using a digital video camera to film the bounce of a tennis ball incident with zero spin at various angles on several different surfaces. The maximum spin rate of a spherical ball is determined by the condition that the ball commences to roll at the end of the impact. Under some conditions, the ball was found to spin faster than this limit. This result can be explained if the ball or the surface stores energy elastically due to deformation in a direction parallel to the surface. The latter effect was investigated by comparing the bounce of a tennis ball with that of a superball. Ideally, the coefficient of restitution ͑COR͒ of a superball is 1.0 in both the vertical and horizontal directions. The COR for the superball studied was found to be 0.76 in the horizontal direction, and the corresponding COR for a tennis ball was found to vary from Ϫ0.51 to ϩ0.24 depending on the incident angle and the coefficient of sliding friction. © 2002 American Association of Physics Teachers. ͓DOI: 10.1119/1.1450571͔ I. INTRODUCTION scribed as fast, while a surface such as clay, with a high coefficient of friction, is described as slow. -
