Biomechanics provides strong support for analysis of sports techniques. Biomechanics has also been valuable for top winter sports athletes, for example in clarifying training targets by technique analysis, finding the best position in the flight phase of ski jumping in wind tunnel experiments, and revealing the merits of "slap skates" through motion analysis. Wind tunnel experiments for ski jumping have been done in Japan since 1951, and the Sapporo Olympic Games were a milestone for advancing the use of biomechanics in winter sports. Currently, the speed and accuracy of data feedback systems for coaches and athletes are markedly advanced. The development of computer systems, especially for kinematics and 3D motion analysis, has yielded useful scientific data for teaching and coaching. Analysis during actual competitions began at the Sapporo Olympic Games, and has since been providing important scientific results for field activities. A new approach to the biomechanics of winter sports was demonstrated at the Nagano Olympic Games under the IOC Medical Commission Sub-commission on Biomechanics and Physiology of Sports. One of the research projects was an analysis of the sports skills of athletes, not only for their safety, but also in order to pass details of their superior techniques and skills to the next generation. Another project was "sports science education", which was newly introduced for the Nagano Winter Olympics to provide the most advanced knowledge about sports sciences and health to children in a way that was easy to understand. Biomechanics plays an important role in supporting physical education in school, as well as top athletes, and it is clear that there is a deep relationship between biomechanics and sports science education. There is a clear need to develop a support system for sports science education that can be used by schoolteachers. Winter sports science is now a highly developed field in Japan, and now needs a research center including biomechanics for systematic and synthetic activities.
