Chalmers Reproservice G¨oteborg, Sweden 2017 Simulation of a Badminton Racket A parametric study of racket design parameters using Finite Element Analysis. Master's thesis in Applied Mechanics ELIAS BLOMSTRAND MIKE DEMANT Department of Applied Mechanics Division of Solid Mechanics Chalmers University of Technology Abstract Badminton, said to be the worlds fastest ball sport, is a fairly unknown sport from a scientific point of view. There has been great progress made to get from the old wooden rackets of the 19th century to the light-weight high performance composite ones used today, but the development process is based on a trial and error method rather than on scientific knowledge. The limited amount of existing studies indicate that racket parameters like shaft stiffness, center of gravity and head geometry affect the performance of the racket greatly. -

Tennis Study Guide
TENNIS STUDY GUIDE HISTORY Mary Outerbridge is credited with bringing tennis to America in the mid-1870’s by introducing it to the Staten Island Cricket and Baseball Club. In 1880 the United States Lawn Tennis Association (USLTA) was established, Lawn was dropped from the name in the 1970’s and now go by (USTA). Tennis began as a lawn sport, but later clay, asphalt and concrete became more standard surfaces. The four most prestigious World tennis tournaments include: the U.S. Open, Australian Open, French Open, and Wimbledon . In 1988, tennis became an official medal sport. Tennis can be played year round, is low in cost, and needs only two or four players; it is also suitable for all age groups as well as both sexes. EQUIPMENT The only equipment needed to play tennis consists of a racket, a can of balls, court shoes and clothing that permits easy movement. The most important tip for beginners to remember is to find a racket with the right grip. The net hangs 42 inches high at each post and 36 inches high at the center. RULES The game starts when one person serves from anywhere behind the baseline to the right of the center mark and to the left of the doubles sideline. The server has two chances to serve legally into the diagonal service court. Failure to serve into the court or making a serving fault results in a point for the opponents. The same server continues to alternate serving courts until the game is finished, and then the opponent serves. -

3D Kinematics Analysis of Overhead Backhand and Forehand Smash Techniques in Badminton
Ann Appl Sport Sci 9(3): e1002, 2021. http://www.aassjournal.com; e-ISSN: 2322–4479; p-ISSN: 2476–4981. 10.52547/aassjournal.1002 ORIGINAL ARTICLE 3D Kinematics Analysis of Overhead Backhand and Forehand Smash Techniques in Badminton Agus Rusdiana * Sports Science Study Program, Faculty of Sports and Health Education, Universitas Pendidikan Indonesia, West Java, Indonesia. Submitted 04 April 2021; Accepted in final form 28 June 2021. ABSTRACT Background. This study aims to analyze the movement of backhand and forehand smash stroke techniques in badminton in three dimensions using a kinematics approach. Objectives. The obtained results were analyzed using a descriptive and quantitative approach. Methods. Furthermore, 24 male badminton players from the university student activity unit with an average age of 19.4 ± 1.6 years, height of 1.73 ± 0.12 m, and weight of 62.8 ± 3.7 kg participated in this study. The study was conducted using 3 Panasonic Handycams, a calibration set, 3D Frame DIAZ IV motion analysis software, and a speed radar gun. Results. The data normalization from the kinematics values of the shoulder, elbow, and wrist joint motion was calculated using the inverse dynamics method. In addition, a one-way ANOVA test was used to identify differences in the kinematics of motion between two different groups. The obtained results showed that the speed of the shuttlecock during the forehand smash was greater than that during the backhand smash. In the maximal shoulder external rotation phase, two variables were identified to have the best results during the forehand smash, i.e., the velocity of shoulder external rotation and wrist palmar flexion. -

When Toblitz How Toblitz
THE BLITZ PLATFORM TENNIS TIPS The Art of BlitzingBY JERONIE BARNES 1 In both football and platform tennis, blitzing involves an aggressive effort made by the defensive team to apply pressure and be disruptive to the offensive team. In platform tennis, a blitz takes place when a player from the backcourt moves forward toward the net and attacks the offensive side when one or both of their opponents are positioned at the net. Although it may look like a reckless, kamikaze attack on the opposition, more often than not, it requires preparation, teamwork, timing, placement, speed, and quick hands to pull off a winning blitz.
