The Engineering of Sport 6
The International Sports Engineering Association (ISEA) was launched in 1998 as a response to the enthusiasm created by the 1st and 2nd International Conferences on the Engineering of Sport. The primary aim of the ISEA is to act as a forum to discuss technical and scientific issues relating to sport and sport technology for those carrying out research and development in this field. The members of the ISEA come from a wide range of disciplines from engineering to sports science, from research organisations, universities and relevant industries world wide. Since the launch of ISEA in 1998 in Sheffield (UK), biannual conferences have took place in Sydney (Australia), Kyoto (Japan), and two years ago in Davis (USA). In 2006 the biannual conference is being held in Munich following the FIFA World Cup 2006 Germany. ISEA publishes the International Sports Engineering Journal, which represents one of the leading scholarly journals in the field of Sports Engineering, now in its 9th successful year.
The editors
"It is fitting that the biggest International Sports Engineering conference so far has been organised by Eckehard Fozzy Moritz. Fozzy is big both in stature and in ideas, willing to do as all good designers do in thinking outside the box. The conference, to which this proceedings refers, will have been an enjoyable affair since Fozzy rarely does anything without fun (or at least with an element of the unexpected)! Fozzy was instrumental in setting up DIVERS, the German society for sports engineering, and now has a dynamic group of people around him in his unique centre for innovation in sports, the SportKreativWerkstatt. The design of this proceedings is testament to the hard work of Fozzy and his team in the creation of something dynamic and yet different for the world of sports engineering." Stephen J. Haake
"Steve Haake IS sports engineering. With the organization of the first conference on sports engineering in 1996, and the editing of the very first set of proceedings on this topic, he was the one who made this field popular in the world and acceptable in academic circles. Further milestones followed that are all still successful today: The foundation of the International Sports Engineering Association that he has chaired for almost a decade, the establishment of a scientific journal on sports engineering, the origination of novel institutions like the Sports Engineering Network and SportsPulse in England; and since March 2006 Professor Haake is head of the Centre for Sports and Exercise Science at Sheffield Hallam University.
The secret to Steve's success is openness and hospitality. When I approached him in 1998, to learn more about sports engineering and how to relate this to my own field of innovation, Steve was simply inviting me over to his place and shared ideas, competence and knowledge with me. Similar encounters followed that greatly helped my work: I have to say I am very proud to have Steve as a co-editor of these proceedings." Eckehard Fozzy Moritz
Synopsis of Climbing- Pulley Mechanics and Taping
Franz Konstantin Fuss
Division of Bioengineering. School of Chemical and Biomedical Engineering, and SPERT (Sports Engineering Research Team). RioMcdical Engineering Research Centre, Nanyang Technological University. Singapore Finger pulleys arc fibrous sheaths. which tic the finger flexor tendons to the bone by avoiding the bowstringing effect. The latter is a separation of the tendons from the bone, which usually occurs after pulley rupture. Although bowstringing would lengthen the moment arm at the finger joints, it increases the relative amount of muscle shortening beyond the limit of force production. Finger pulleys arc divided into weaker cruciatc and stronger annular pulleys. which arc aligned in alternative sequence. The most important pulleys, prone to injuries are: A2 at the proximal phalanx. A3 at the proximal interphalangeal joint, and A4 at the middle phalanx. Finger pulley injuries occur almost exclusively in sport climbing and account for about 45% of finger injuries and about 20X, of all climbing injuries and overuse syndromes. Severe bowstringing occurs only if more than one annular pulley is ruptured. which requires surgical treatment.
Taping. adhesive bandages at finger segments and joints, are said to exert a supportive effect to the pulleys in terms of load sharing. Conventional tape is arranged as circular or figurc-x shaped loops. (sonst noch ctwas wichtiges uber taping"?"). Current research on pulley mechanics and taping extends to
I) accurate measurement of friction between tendons and pulleys.
2) biomechanical influence of taping.
3) biorncchanical model of the pulley loop in axial and side views and its application to surgical pulley replacement.
4) finite clement model of pulleys in side view. with 19 fibres per pulley
5) modelling of pulley ruptures. and
6)
Higher friction between tendons and pulleys would benefit the climber. as this saves muscle force and delays fatiguing. The direct influence of taping on load sharing between tape and pulley is small. about 10%: yet there is an indirect influence. as taping reduces flexion of the proximal interphalangeal joint and thus lowers the load on the pulleys. Exact positioning of a pulley graft during replacement surgery is critical and affects the success of the treatment; biomechanical models can give hints for graft placement, however. they depend on exact input data. Finite clement models of pulleys provide the exact force distribution over the pulley fibres. with peak forces in the mid- and lateral fibres in extended and flexed fingers respectively, Pulley"
