The ski rental problem arises from the following scenario. You want to start skiing, but you don’t own any skis. On each day you go skiing, you can either choose to rent skis for cost 1, or you can buy skis for cost s. Since you don’t know when you might get sick of skiing, (or when you might break your leg and be unable to ski again), the number of days d that you will end up skiing is unknown...

PATIENTS AND METHODS 140 patients with aortic dissection type A were admitted for cardiac surgery. Seventy-seven patients experienced their dissection in the winter season (from November to April). We analyzed cases of ascending aortic dissection associated with alpine skiing. RESULTS In 17 patients we found skiing-related aortic dissections. Skiers were taller (180 (172-200) cm versus 175 (1...

We obtained indices of home advantage, based on the medals won by competing nations, for each event held at the Winter Olympics from 1908 to 1998. These indices were designed to assess home advantage while controlling for nation strength, changes in the number of medals on offer and the performance of 'non-hosting' nations. Some evidence of home advantage was found in figure skating, freestyle ...

A large number of injuries to the lower extremity occur in skiing and snowboarding. Due to the difficulty of collecting 3D kinematic and kinetic data with high accuracy, a possible relationship between injury statistic and joint loading has not been studied. Therefore, the purpose of the current study was to compare ankle and knee joint loading at the steering leg between carved ski and snowboa...

Skiing is an increasingly popular sport amongst both adults and children. Opportunities for skiing within the United Kingdom are limited, but the introduction of increasing numbers of dry ski slopes has made the sport more available. The nature of injuries sustained by adults on snow and dry slopes is well documented, but this is less true of childhood injury, especially on dry slopes. A consec...

All skiing injuries presenting to a fracture clinic during the period December 1992 to April 1993 were studied. Fifty five patients with 59 injuries were treated during this period. Thirty (54.5%) were male and 25 (45.5%) female. The mean age was 34 years (range 9-61). The anatomical distribution of injuries seen corresponded very closely with those seen in much larger studies abroad. There wer...

This review article reports the recent advances in the study, design and production of ski-boots for alpine skiing. An overview of the different designs and the materials used in ski-boot construction is provided giving particular emphasis to the effect of these parameters on the final performances and on the prevention of injuries. The use of specific materials for ski-boots dedicated to diffe...
