Editorial

The first online issue of the Scientific Journal of Orienteering Dear Reader The Scientific Journal of Orienteering has been an official publication of the International Orienteering Federation (IOF) for more than twenty years now. Founded and for many years published by Roland Seiler, he eventually handed the editorial work over to Toni Held and Torgny Ottosson. Now it is time for another change, and the editorship has passed to me. Torgny Ottosson and I are publishing this issue together in order to provide a straightforward changeover. I would like to thank Torgny very much for all his work. The Scientific Journal of Orienteering has been published as a printed journal so far. Adapting to modern trends with the intention of making the ScJO available to as many orienteers and scientists as possible, it will from now on be published only in a free accessible online version, linked to the official website of the IOF. In this context I would like to say thank you also to Roland Seiler and Toni Held who have supported me a lot in planning my editorship. For Torgny and I, it is a great pleasure to publish this issue as it is full of very different and interesting articles, demonstrating the many facets of orienteering and also the high quality of the authors. Furthermore, the journal’s topicality is emphasised through two articles that are very closely related to the 2005 World Orienteering Championships in Japan. The first article, by Zürcher S, Clénin G and Marti B, may give an answer to the success of the Swiss National Team in Japan. In preparing for the special demands of Japanese terrain, the question was posed of how closely aerobic capacity testing meets the special running demands of orienteering. In answering this question Zürcher et al. invented the so called ‘Japan-test’, in which the Swiss Orienteering National Team ran on a treadmill device with an ‘uphill’ mat. What they found out is very interesting and, in my opinion, in this instance surprising. It underlines the special demands on running capacity in orienteering. Pack formation in orienteering cannot be eliminated. Because start intervals in international competitions have been shortened in order to increase the spectators’ enjoyment, world class orienteers have got even more used to this phenomenon over the last few years. Yet still, discussions arise after every important competition. And the more important the competition, the bigger the discussion. Ackland JG shows in his article that one can analyse final results very precisely by including pack formation in calculations, and demonstrates these effects for the long-distance final competition in WOC 2005. Maybe in future it will even be possible to consider this formula in course planning and defining the starting intervals, so as to reduce pack formation? Koukoris K presents a very substantial sociological study on how beginners became involved in orienteering in Greece and what their motivation was. In relation to the IOF’s aim of developing orienteering as an Olympic sport, this article is very important in respect of describing strategies on how to get more participants in orienteering. Pribul RF and Price J analyzed race strategies and running speed of elite and non-elite orienteers in different classes. The result showed no difference between elite and non-elite classes but, surprisingly, perceived and performed strategy vary a lot. Lyme borreliosis is a bacterial infection with Borrelia burgdorferi transferred by tick bites. Orienteers in regions with endemic Lyme borreliosis – that is large parts of Europe and North America - are at great risk of getting infected. Fahrer H et al. wrote in the Scientific Journal of Orienteering in 1993 that in Switzerland more than 40% of orienteers showed positive serologic testing, but less than 10% had suffered from symptoms. During the last ten years it has been recognized that a chronic clinical form of Lyme borreliosis exists, leading to persistent symptoms – sometimes even after adequate antibiotical therapy. As chronic Lyme borreliosis is not a well known entity, Satz N, rheumatologist and a leading Swiss tick-transferred disease specialist, gives a very good overview of the state of the art of diagnosis and adequate treatment of chronic Lyme borreliosis. Knowing of several cases where diagnosis and adequate treatment or alternative treatment options of rheumatologic symptoms have led to an over-rapid connection to Lyme borreliosis,

this article gives good answers on what is real evidence and what is speculation or humbug. It has to be emphasized that treatment can only be successful if there has been correct diagnosis. And the ‘book on borreliosis’ cannot be closed yet, too many questions remain. Due to some delays in translation of the article, the German version will be published in this issue and the English version in the next issue; we are sorry for this inconvenience caused. Finally, I would like to motivate every reader to submit his or her own contribution. As you can see, many different aspects of orienteering are worthy of discussion. The success of the Scientific Journal of Orienteering is dependent on the contributions. And the contributions are created by you! But now: Enjoy your reading! Kind regards André Leumann

Uphill running capacity in Swiss elite orienteers. Zürcher S, Clénin G and Marti B From the Swiss Federal Institute of Sport, Magglingen, Switzerland Abstract PURPOSE: To quantify uphill running capacity in a laboratory treadmill test with Swiss elite and junior orienteers, and to evaluate the differences between flat and uphill running capacity. METHODS: 32 elite orienteers (M=18, F= 14) aged 21.8 ± 4.1yr were tested twice to voluntary exhaustion, first in the standard Swiss Olympic lactate threshold test, and second in a graded uphill test at 22% incline. 3-4 hours rest were given between tests. To achieve similar workloads, uphill treadmill speeds were reduced to 40% of the flat test. Stages continued 3 minutes, and increased 0,7 km/h per stage. Heart rate, lactate, and Borg were collected. To enable comparison, maximal uphill speed (Vmaxuphill) was converted to an “equivalent flat speed”. RESULTS: Mean Vmaxuphill was faster than Vmaxflat in both men (+7.2% p
