Sport technology conference, Malaysia Thursday, 9-10am

Dr. Wolfgang Potthast (K1) biomechanics and sport

muscle adaptation

ana-bolism (hypertrophy) neuronal adaptations strength increase


muscle-tendon injuries kata-bolism (over training) strength decrease / injury


bone -    diameter, length, density (can increase due to mechl load) -    damage injuries – periostitis, fractures, stress factures

cartilage -    stiffer, greater surface -    damage injuries – fissures, osteo arthiritis


performance enhancing


injury prevention

v close together – cannot easily distinguish

performance enhancing -    training interventions -    direct info in competition -    improvement of equipment

injury prevention -    ethical aspects -    economical aspects -    reduce non-training time

biomechanics, 4 bigger fields -    muscle activity (Electromiography) -    kinetics, kinematics – movement of pointof origin of body over time and space -    kinetic – forces acting on boil structures

focus on kinetic first -    forces measured through deformation -    which lead to electric signals (force-demaraction characteristics)

limited insights, as need insight into what is generating the force

for skiing

compact body ski position adv

correlations small

ballitic variables relevant in flight

performance determing factors -    3 dimensional kinematics -    difficult environmental conditions

time costs -    3 months prep -    1 day measuring -    1 year analysis

unapplicable for standard performance analysis -    manual digitisation – 12,000 clicks per trial

semi-automatic digitisation: -    reflective markers on landmarks -    video camera to record motion -    software detects markers

markerless tracking -    ‘time of fight’ – light beam detects movement; time difference to reach light sensor, can calculate -    3 dimensional reconstruction

injury prevention -    to prvent athletes fom injuries, t injury mechanisms have to be understood -    internal forces and mechl stresses must be known -    measuring external forces not sufficient

internal loadin measuremenet s- in vivo measurement of Achilles tendon Komi 91, komi and belli 96 - inserted pin into achilles and measured forces - subsequently used optic fibre technique – needle used to insert fibre, then removed leaving only fibre

in vivo measurement of intradiscal pressure nachemson and morris 63, wilkie et al 2001

in vivo measurment of hip joint forces (prosthetics) graichenn and Bergmann 1991

challenges accurate and valid diagnostic tools for strength measurements fast, easy tools for accurate motion capturing tools to detect motion of bony structures fast, non-invasive, without radiation (models?)

Hamdan Ahmad Quality Improvement in Sport: Change Through Teamwork

ME: philosophy of ‘new thinking’ something related to web 2.0

other factors influ effectiveness of organisation -    more than poduct

requires commitment by entire organisation to improve quality

implementing of change process

ME: link to theories of technological change

greatest effect on sport quality -    enhance team spirit

ME: doping control?

successful cyberathletes possess following 1.    high degree of computer literacy 2.    strong mental agility and dexterity 3.    intensive training 4.    disciplined 5.    free from drugs and smoking (healthy lifestyle)

cyberathletes are also stricthly subject to rules and no particupant nder 16 allowed to participant

Electronic Sports World Cup (France)

Asian CyberGames Tournament (China) -    gov sponsored

south korea – branding

Samsung invests over $12m yearly in wCG korea and is

US – commerciability -    cpl attracts large sponsorship

Singapore – gov support -    gov active promoter of cybergames resulted in Singapore awarded host nation of WCG

designed to suit special people – ‘the Dwarf’

4ft 10inches or less at adult height is category of dwarf – genetic

ball bsall is 7cm – 9cm, weights 15g-32g diff from normal softer, lighter, bouncing rater slower easy for dwarf

racket 55cm long – much shorter than normal

Globalisation and the Malaysian Sports Industry Aminuddin Yusof,


culturally -    greater international cultural exchange -    greter international travel and tourism -    spread of local foods to other countries -    world wide fads and popular culture such as pokemonm sudoku -    world wide sports such as FIFA and Olympics

internationalization of sports

international diffusion of sports

Malaysian version of tour de france

international mediatization of sports

Malaysian sports industry -    young and emerging industry -    comprise mainly of small to med-sized businesses -    most companies do not see themselves as part of a broader sports industry

development of IPR

role ofUni -    data collection and info center: no data in Malaysia to describe sports industry and its performance -    sport management programes -    business skills for coaches and former athletes
