Celem pracy była ocena niektórych parametrów chodu osób z chorobą Parkinsona przy przechodzeniu odcinków prostych określonej trasy i slalomu. Badaniem objęto dwie grupy: grupę badawczą złożongą z 17 chorych na chorobę Parkinsona (średnia wieku 71 lat) i 17-osobową grupę kontrolną reprezentowaną przez osoby zdrowe (średnia wieku 70 lat). Badanie polegało na przejściu trasy, uwzględniającej odcinki proste i slalomu, wytyczonej wg pomysłu autorów pracy. Osoby z chorobą Parkinsona osiągały gorsze parametry chodu w stosunku do osób zdrowych w analogicznym przedziale wiekowym, zwłaszcza na odcinkach slalomu.

The aim of the paper was to evaluate chosen gait parameters in patients with the Parkinson's disease while walking on straight sections and slalom of a chosen route. The research covered two groups: the examination group numbering 17 patients with the Parkinson's disease (average age 71 years) and the control group including 17 healthy people (average age 70 years). The examination was based on covering a route consisting of straight sections and slaloms, designed according to the idea of the authors. Patients with the Parkinson's disease achieved worse results in comparison with healthy people of similar age, especially on the slalom distances.

Purpose. The aim of the overall research on alpine skiing was examination of the biomechanical approach to tactics of running a course. The aim of this particular paper was presentation of first results on the geometry of courses of four disciplines. Basic procedures. The research covered competitions of alpine skiers during the 2006/2007 FIS World Cup. All four alpine skiing disciplines, i.e. downhill, super giant, giant slalom, and slalom, were taken into account. Each discipline was studied three times: in Italy, Austria, Germany, Slovenia, and Norway. 54 to 82 alpine skiers took part in each of the competitions. Differential GPS for geometry of gates setting and video camera for time data were used. Then the distribution of velocity for each runner along the entire course was calculated. Main findings. The first data on geometry of the ski courses revealed a large difference in vertical drop and length between the disciplines, with the angles of inclination, however, being similar. Conclusions. The knowledge of detailed geometry of ski courses is important since up to one-third of competitors do not finish particular runs. It happened that as many as ten skiers ran off the course at the same gate.
