Sports Engineering Around The World:

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 ( 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

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
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.
