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). -
Ball Change in Tennis: How Does It Affect Match Characteristics and Rally Pace in Grand Slam Tournaments?
Original Article Ball change in tennis: How does it affect match characteristics and rally pace in Grand Slam tournaments? JAN CARBOCH 1 , MATEJ BLAU, MICHAL SKLENARIK, JAKUB SIMAN, KRISTYNA PLACHA Department of Sport Games, Faculty of Physical Education and Sport, Charles University, Prague, Czech Republic ABSTRACT Tennis balls degrade after fast racket and ground impacts until they are changed after agreed number of games. The aim is to analyse the new (after the ball change) and used balls (prior to the ball change) match characteristics and the frequency of rally shots in matches in the Australian Open, French Open and Wimbledon in 2017. Paired samples t-tests and Cohen d were used to compare the point duration, number of rally shots, time between the points, rally pace and work to rest ratio among these tournaments. There was a significant difference in rally shots number played with the new balls (4.17 ± 0.86) compared to the used balls (4.60 ± 1.10) in female matches (p = 0.047); in males matches large effect size was found (d = - 0.83) in the same variable with the new balls (4.44 ± 0.57) and used balls (4.95 ± 0.66), both happened in the Australian Open. No difference was found between the new and used balls in the rally pace in all the observed events. The Wimbledon match characteristics were least affected by the ball change. The ball degradation affected the match characteristic the most in the Australian Open, in terms of more rally shots, but not slowing down the rally pace. -

A stereophotogrammetric system (Smart-D, BTS, 8 cameras, 550 Hz) was used to track the table tennis racket during cross-court (CC) and long-line (LL) shots. Ten national level players completed ten CC and ten LL top spin strokes responding to a robot machine. The racket motion throughout the shot showed specific technical characteristics: the minimum height of the racket was detected during the backswing phase; racket height at the end of backswing phase (maximal distance racket/table) was higher than the minimum; height at Citation: Malagoli Lanzoni, I.; the racket maximum velocity (ball/racket impact) was greater than the net’s height. -
All Tennis Grips Explained Clearly
All Tennis Grips Explained Clearly The tennis grips you use have a big influence on your style of play. This is because the tennis grip is one of the factors that determines how much of spin you put and how much of pace you generate. One grip is not better than another. You should select a grip that helps your style of play. If you are an aggressive player, choose a grip that allows you to hit through the ball and put more pace (think Federer). If you are more of a consistent player, choose a grip that allows you to put more spin (think Nadal). The tennis racket grip is divided into 8 bevels as shown in the diagram. The type of grip depends on which bevel the Index Knuckle and Heel Pad rest. All of the tennis grip diagrams below assume that you are right handed. If you are left handed just reverse the instructions. Serve Continental Grip Use this for the serve, volley, overhead, and slice (all the pros do). The Index Knuckle and Heel Pad rest on bevel 2. Forehand There are three forehand grips. Each grip has its own natural height at which you would contact the ball. The higher the natural contact point, the more naturally you hit across the back of the ball from bottom to top, and more top spin you put on the ball at the expense of pace. This will be clearer as you read about the three forehand grips. Eastern Forehand Grip Index Knuckle and Heel Pad rest on the 3rd bevel. -

People such as Maurice McLoughlin, a contemporary champion in 1915, wrote “’Strokes on the left- hand side of a right-handed player, and vice versa, are taken in what might be called the most ‘unnatural’ position in tennis. The backswing is much more hampered than in any other stroke. The strength of the wrist is much more demanding…all these things make the ordinary backhand stroke an awkward one…’ J. Parmly Paret wrote in 1927 ‘The backhand stroke is one of the greatest stumbling blocks for every beginner…if you’re like the average player, you’re pretty relaxed on the forehand, but when you see a ball coming to your backhand you cringe, ‘Dear God, it’s a backhand’(cited in Tabak, 1991, p. -

THIS CONTENT IS A PART OF A FULL BOOK - TENNIS FOR STUDENTS OF MEDICAL UNIVERSITY - SOFIA https://polis-publishers.com/kniga/tenis-rukovodstvo-za-studenti/ A brief history of tennis 1. Origin and development of the game Ball games were popular in ancient Rome and Greece under the name of a spherical "ball game". In the 11 th and 12 th centuries, the games of "Jacko del Palone" and "Jaco de la Corda" were mentioned, which resembled modern tennis (Todorov 2010; Mashka, Shaffarjik 1989). In the 14 th century, outdoor and indoor courts started to be built in France, where the game of "court – tennis" was played, which was later renamed "palm game", that, dependent on being played inside or outside, was called "short tennis" and " long tennis" (Penchev 1989). Antonio Scaino da Salò’s book "Treatise on the game of the ball" (1555) describes the game instruments - a racquet and a ball - a tight ball of wool, wrapped in leather. It was struck with the palm of the hand, wrapped in a leather belt and a wooden case. A glove was used as well to protect against pain and traumas (Mashka, Shaffarjik 1989). The "court - tennis" game became popular predominantly amongst the nobles in Europe under the name of "Jeu de paume" – palm game, played both indoors and outdoors. “Mirabo” hall, part of the famous Versailles Palace that was transformed at that time by the Sun King - Louis XIV into a main residence of the French kings, exists to this day and had served for that purpose.
