Certainly that is true of skiing competition where the demands on equipment and the performance pressure on athletes are tremendous — and not just on elite skiers, but increasingly on participants at ev...

Balance is hypothesized to be important in alpine skiing, while it is known that balance depends on anthropometric indices. The aim of this investigation was to explore the association between balance, anthropometrics and skiing-results over two competitive seasons among youth alpine-skiers. Eighty-one skiers (40 females) participated in this study. The participants were tested twice over two c...

OBJECTIVES To provide an overview of ski injuries in Norway and to describe the changes between 1990 and 1996. METHODS All ski injuries (7966) treated at four hospitals providing health care to a defined population of about 11% of the Norwegian population were registered prospectively from 1990 to 1996. For this study, 6462 injuries sustained in cross country skiing, downhill skiing, telemark...

Elderly people are the most growing part of the population in developed countries (Europe, North America and Japan). This population is getting more and more alone and isolating this part of the population is the big issue of this century. This isolation can lead to a lack in physical and cognitive activity. Because virtual reality has given good results in health domain, we decided to design a...

The aim of this study was to investigate the interaction of potential intrinsic and extrinsic risk factors in ACL injured recreational female skiers. 93 female recreational skiers who had suffered a non-contact ACL injury and 93 age-matched controls completed a self-reported questionnaire relating to intrinsic risk factors (menstrual history, BMI, previous knee injuries, self reported weekly sp...

The purpose of this study is to clarify the advantages and disadvantages of acceleration measurements in cross country skiing using a body mounted kinematical inertial measurement system. A high profile world cup athlete performed two test-runs in diagonal stride technique on skis and roller skies equipped with an inertial measurement system. In particular the acceleration of the athlete’s cent...

External forces, such as ground reaction force or air drag acting on athletes' bodies in sports, determine the sport-specific demands on athletes' physical fitness. In order to establish appropriate physical conditioning regimes, which adequately prepare athletes for the loads and physical demands occurring in their sports and help reduce the risk of injury, sport-and/or discipline-specific kno...

Introduction The recent death of a junior soldier following a civilian boxing match raises the question of the safety of boxing as a sport. Rosenbaum1 found that in 1962, in terms of injuries received per period played, boxing was less dangerous than skiing, rugby football and association football. We decided to look at the different types of injury received, the length of stay in medical units...
