Comparisons of the ski turn techniques of experienced and intermediate skiers

We compared selected kinematic variables for four different ski turn techniques performed by five experienced and five intermediate male skiers. The four ski turn techniques were the upstem turn, the downstem turn, the parallel turn and the parallel step turn. Each turn was divided into the initiation phase and the first and second steering phases. Most of the statistically significant differences (P < 0.05) between the two groups were found for the initiation phases of the four turns. Both the hip axis-hand axis angle and the edging angle of the uphill ski were significantly different between the two groups for the upstem turn at the beginning of the initiation phase. For the downstem turn, significant differences between the groups were found at the start of the initiation phase for the hip axis-hand axis angle, the shoulder axis-fall line angle, and the edging angle of the uphill ski. The standard deviation of the distance between the tips of the two skis over the second steering phase also differed significantly between the two groups. For the parallel step turn, significant differences were found at the start of the initiation phase for the edging angle of the downhill ski and the downhill ski to movement direction angle. Significant differences were also found for the edging angle of the downhill ski in the middle of the second steering phase and the shoulder axis to movement direction angle at the end of this phase. For the initiation phase of the parallel turn, significant differences were found for the timing of setting the ski pole, the uphill knee angle at the start of this phase and the range of the knee angle of the uphill leg from the start to the end of this phase. For this turn, significant differences between the two groups were also found for the edging angle of the downhill ski in the middle of the second steering phase and the shoulder axis to movement direction angle at the end of this phase. One of the reasons it was possible to identify a few significant differences only for the turns analysed, was the variability within the intermediate group: for most of the variables analysed, the standard deviation was much higher for the intermediate than for the experienced group.     

Inter- and transdisciplinary university: A systems approach to education and innovation

In response to various pressures for change arising from the present situation, the university will have to adopt a new purpose which may be recognized as a means of increasing the capability of society for continuous self-renewal. With this new purpose in mind, the structure of the university will be determined by the concept of an integral education/innovation system for which four principal levels are considered: empirical, pragmatic, normative and purposive levels. From multi-, pluri-, and crossdisciplinary approaches, all pertaining to one systems level only, the university is expected to develop increasingly interdisciplinary approaches, linking two systems levels and coordinating the activities at the lower level from the higher level through common axiomatics. Ultimately, the entire education/innovation system may become coordinated as a multilevel multigoal hierarchical system through a transdisciplinary approach, implying generalized axiomatics and mutual enhancement of disciplinary epistemology. Current university approaches to develop interdisciplinary links between the pragmatic and normative systems levels are discussed. Finally, a transdisciplinary structure for the university is briefly outlined; its main elements are three types of organizational units-systems design laboratories, function-oriented departments, and discipline-oriented departments-which focus on the interdisciplinary coordination between the three pairs of levels in the education/innovation system, i.e., on method and organization rather than on accumulated knowledge. An important role for policy sciences is seen in the linkage between the top pair of systems levels.

Résumé Pour répondre aux sollicitations de son environnement actuel, l'Université devra se donner de nouveaux objectifs en partant du principe qu'il lui faut procurer à la société les moyens d'un renouvellement continu. On peut déduire la structure de l'Université, qui est ainsi exigée, de l'idée d'une liaison intime entre éducation et innovation: aux quatre niveaux à considérer, niveau empirique, niveau pragmatique, niveau des normes et niveau des stratégies. On attend de l'Université que, dépassant les activités multi- ou pluridisciplinaires qui ne se situent qu'à un niveau du système, elle réussisse à élaborer une méthodologie interdisciplinaire lui permettant de relier les différents niveaux et de coordonner d'un bout à l'autre du système les activités conformément à une logique unifiée. En somme, le système d'éducation et d'innovation considéré dans son ensemble pourrait tendre vers le modèle d'un système intégrant hiérarchiquement des niveaux et des objectifs multiples, grâce à une méthodologie transdisciplinaire impliquant le développement d'une logique généralisée et des échanges réciproques entre l'épistémologie des différentes disciplines. L'article soumet à la discussion les méthodes dont usent aujourd'hui les universités pour établir des liens d'interdisciplinarité entre le niveau pragmatique et le niveau des normes. En conclusion, est présentée une brève esquisse de ce que pourrait être la structure transdisciplinaire de l'Université: trois types d'unités s'y trouvent distingués dans l'organisation, les laboratoires d'élaboration des projets, les départements tournés vers la satisfaction d'une fonction et les départements tournés vers le travail dans une discipline; l'accent y est mis sur la coordination interdisciplinaire dans les trois mises en relation unissant deux à deux chacun des quatre niveaux du système d'éducation et d'innovation, autrement dit, sur la méthode et l'organisation, plus que sur l'accumulation de la connaissance. On fait voir le rôle important qui est réservé aux sciences de la décision dans la mise en relation des deux niveaux supérieurs du système.

“When you're down,stay down”: A lesson for all competitive alpine skiers supported by an ACL rupture measured in vivo

BackgroundDuring an experiment, a ski racer equipped with various measurement devices suffered an anterior cruciate ligament (ACL) rupture in his right knee. The aim of this study was to describe the underlying injury mechanism from a functional perspective.MethodsEight giant slalom turns (i.e., 4 left turns), followed by 1 left turn at which the ACL injury occurred, were recorded by 2 video cameras, electromyography of 4 relevant muscle groups, inertial measurement units to measure knee and hip angles, and pressure insoles to determine ground reaction forces.ResultsDue to a loss of balance, the ski racer began to slide sideways at the apex of a left turn. During sliding, his right (outside) leg was actively abducted upward without touching the ground. The ski racer then attempted to stand up again by dropping his leg back towards the snow surface. The end of this dropping was accompanied by a decrease in electromyographic activity in the knee stabilizing muscles. Once the inside edge of the outer ski caught the snow surface, a rapidly increasing peak force, knee flexion, and an aggressive sudden activation of the vastus medialis muscle were observed, while biceps femoris and rectus femoris further decreased their activation levels. This likely resulted in excessive anterior translation of the tibia relative to the femur, causing damage to the ACL.ConclusionOur example emphasizes that ski racers should not get up until they stop sliding. Remember: “When you''re down, stay down.”
