The 5th International Conference on Sports Engineering, will be held September 13-16, 2004, in Davis, California, USA. The Conference Chair is: Professor Mont Hubbard, Department of Mechanical and Aeronautical Engineering, University of California, Davis 95616, E-mail: firstname.lastname@example.org Sports Engineering Around The World: Taiwan: Associate Professor Lin-Hwa Wang – National Cheng-Kung University, Taiwan In the past three years, our research has focused on the biomechanics of tennis funded by the National Science Council, Taiwan. Research projects include “Biomechanical Analysis in Tennis Serve” (NSC 88-2413-H-006-006) and “The Analysis of the Correlation between the Motor Function of Upper Extremity and the Velocity of Tennis Serve” (NSC 89-2413-H-006 -004). In sports biomechanics studies, I have collaborated with Dr. Fong-Chin Su who is the chairman of the Institute of Biomedical Engineering and director of the motion analysis laboratory (http://www.ncku.edu.tw/~motion). This lab is equipped with a 6 Falcon- camera (240 Hz) motion analysis system, 4 Kistler force plates, a Pedar insole pressure system and an EMG system. The 12 m (width) x 12 m (depth) x 8 m (height) space is suitable for motion capture for sports. Professor Su is interested in biomechanics of human movement, muscle mechanics, gait analysis, orthopaedic biomechanics and tissue engineering. The project that we just completed and ongoing project are as following: Biomechanics Analysis in Tennis Volley (NSC 89-2314-B-006-134-M08): The volley is the most power weapon in today’s tennis competition especially in doubles. Excellent volley skills can help win the game. A three-dimensional motion analysis system (Motion Analysis Corporation) was used for collecting motion data. The three- dimensional analysis model of the upper extremities was developed to analyze the kinematics of the segments and joints. Understanding the 3D biomechanical behavior of upper extremity during different types of tennis volleys could allow tennis players and coaches to improve the performance of tennis technique and prevent injuries. It is also helpful for physicians and therapists in the diagnosis of sports injuries and clinical treatment. Optimal Camber Angle in Wheelchair Athlete (NSC 91-2413-006-010H): Doing exercise is a basic right for every human being and it is good for health. For the disabled, doing exercise not only improves their vitality, but also increases their confidence. The purpose of this study is to use the motion capture system and force measuring system to quantify the kinematics and kinetics data in wrist, elbow, and shoulder at different angles of wheel camber. From these data, we could learn how to promote the performance of wheelchair propulsion, to decrease the possibility of injuries occurred and to optimize wheelchair propulsion from a biomechanical point of view. United Kingdom: Dr. Jane Blackford – School of Engineering and Electronics and Centre for Materials Science and Engineering, The University of Edinburgh, Scotland, UK Dr. Jane Blackford shares a day in her life as she conducts “Sports Engineering and Ice Mechanics Activities”. 22 February 2002. Day spent in Glencoe at Mountain Technology discussing a project on ice screws. We drive North to Fort William. The snow’s looking good for climbing tomorrow. There's a message on my mobile: “ …we’d like to interview you about your part in the success of the women’s curling team in the Olympics for the Sunday Telegraph”. I call them back. We chat about the curling victory at the Salt Lake City Olympics and my involvement with the sweep ergometer and the British team. Back to the start of 2000 – having recently arrived in Edinburgh I'm looking for research collaborators and keen to set up activities linking engineering, materials and sport. I meet Dave Saunders, a physiologist who works with elite athletes. We visit Mike Hay, Scottish curling coach, and agree to work on a sweep ergometer for training curlers. Over the next year or so we build a device and characterise the players sweeping ability. Shortly before the Olympics we spend a day taking data from the ladies curling team. Interesting results – the players show quite different characteristics. From my developing understanding of curling and ice friction I explain our findings and we discuss how this could influence their sweeping tactics. This work sparked an interest in ice which has developed over the last couple of years. My research group focuses on ice mechanics and sports engineering. We work on winter sports: climbing, curling, skiing, and snowboarding. I'm based in the School of Engineering and Electronics and Centre for Materials Science and Engineering at the University of Edinburgh. A strong area of research is ice friction. A major aim of the work is to understand the frictional processes occurring between a material and ice (or snow), and from this scientific understanding design materials and surfaces for improved friction control on snow or ice – so to make skis slip more and tyres grip more. We have an enthusiastic team working on this: Dr Vasileios Koutsos (tribology and atomic force microscopy expert – and the keenest physicist I've ever met); Dr Brett Marmo glaciologist from Australia (gets very excited about ice – which is great); Dr Chris Jeffree (expert in low temperature scanning electron microscopy, background in botany but with a growing interest in snow and curling); and Dr Michael Zaiser (who can theorise and model just about anything, he can ski pretty well too). Snow is a complex and fascinating material. Michael and I are starting to work on avalanches – theory and predictive modelling based on experimental structure-property relationships in snow. Daniel Higgins is the most recent member of the ice friction team (November 2002) – he's doing a Ph.D. on tyre-ice friction in collaboration with Ford, Jaguar, Goodyear supervised by myself and Vasileios. Pete Watson and MP (Mark-Paul) Buckingham – my Ph.D. students – are working on instrumenting skis and snowboards. This is to quantify how the skis and boards move under conditions of real use. Dr Iain Lindsay and Alistair Fitchie have given excellent input with electronics, sensors and general instrumentation know-how. Pete's work – in collaboration with Arup – was initially to use novel sensors to monitor the skis, but [given enough freedom from his supervisor] Pete came up with an ingenious idea: to go beyond monitoring the skis and to get them to react to their environment and change their properties for different conditions. MP, also a snowboarding instructor, will use his instrumented snowboards as a training aid for elite boarders. Pete and MP have founded a company – ReacTec Ltd. – to commercialise the "reactive" skis. I continue to be involved in climbing and mountaineering (from both going-out-on-the- hills and academic perspectives). My first postgrad student, Ed Maycock, worked on the development of an attachment loop for a climbing harness in collaboration with a UK mountaineering equipment manufacturer Troll Ltd, funded by Steve Haake's DTI initiative. For a number of years I've been involved with the British Mountaineering Council Technical Committee – here I get to apply my metallurgical skills along with a knowledge of climbing to various items of failed equipment. In addition it generates rather exciting examples and case studies for our honours course on deformation, fracture and failure of materials. Much of this accumulated expertise has been set out in my chapter (Materials in mountaineering) for Mike Jenkin's book on Materials in Sport – which should be in print in early 2003. United States: Professor James Sherwood - Department of Mechanical Engineering and Director University of Massachusetts-Lowell Baseball Research Center The University of Massachusetts-Lowell Baseball Research Center (UMLBRC) was founded in 1998 with a $400K seed grant from Major League Baseball and Rawlings Sporting Goods. The mission of the Baseball Research Center is be a resource for applying scientific and engineering methods to understand the equipment used in baseball and for the education of students interested in these applications. Since its inception, the Center has concentrated on bats and balls and received over $600K in grants from sponsors such as the NCAA, MLB, NFHS (National Federation of High Schools) and numerous bat and ball manufacturers. Professor James Sherwood of the Department of Mechanical Engineering is the director of the facility. There are presently 12 undergraduate and 5 graduate students doing research at the UMLBRC. In 1999, the UMLBRC was tasked by the NCAA to develop a test protocol for evaluating the performance of non-wood (aluminum) bats. The NCAA was concerned that the college game was becoming more and more biased to the offense with the advent of ever improving alloys. To maintain the integrity of the game and balance of offense vs. defense, the NCAA moved to put a ceiling on bat performance and needed an independent facility to develop the test standard and be available for compliance testing. The UMLBRC was fortunate to be awarded those tasks. As a result, all bat models must first be evaluated at the UMLBRC and pass performance limits before the model can be used in NCAA competition. In 2000, the UMLBRC completed an exhaustive study for MLB to investigate as to whether or not the major league baseball had been “juiced”. In April 2000, a record number of homeruns had been hit, and MLB and baseball fans were concerned that the baseball was livelier than in past years. Larry Fallon, a doctoral candidate at the UMLBRC, worked with Dr. Sherwood and MLB to examine every phase of the manufacture of the baseball as well as its performance in static and dynamic tests. This investigation included a visit to the Rawlings facility in Costa Rica, where the baseball is assembled, as well as visits to the manufacturers of the rubber pill, the wool windings, the cowhides and the cotton laces. The outcome of the study was that the baseball was made and performed within MLB specifications. The record homeruns was not due to a “livelier” baseball. There are currently 3 major MS thesis being pursued at the UMLBRC. Patrick Drane, a current MS candidate and Massachusetts native, is investigating the effect of work hardening on aluminum baseball bats. Using the Center’s state-of-the-art hitting machine, baseball bats have been subjected to repeated “perfect” hits. The goal of the research is to conclude as to whether or not the performance of metal bats increases or drops due to use in the field. This thesis is also exploring how moisture content affects the performance of wood bats. The goal of this study is to understand how changes in climate and storage may affect wood bat performance at the major league level. Gayatri Vedula, an MS candidate from India, is studying the relationship amongst the COP (center of percussion), vibrational node in the barrel and sweet spot using experimental and numerical methods. Shintaro Nabeshima, an MS student from Japan, is completing an experimental study to compare the batted-ball performance of US vs. Japanese bats.
