Skiing and snowboarding are very popular sports in Switzerland. However, every year, around 67,000 skiers and 18,000 snowboarders are injured so seriously that they need medical treatment. Moreover around 8 people die on the slopes in Switzerland. Therefore, there is a need to reduce the burden of injuries in snow sports. The Swiss Council for Accident Prevention (bfu) developed a strategy that utilized scientifically-based injury prevention, using an effect-oriented prevention cycle. The aim of this study is to present this systematic and evidence-based strategy for snow sports.

The process by which young talents develop to become top-class players once they reach the age of maximum performance is influenced by numerous factors. Among the exogenous factors, the family plays a central role. In the context of a research project carried out in cooperation with the Swiss Football Association SFV, 159 former members of the national youth football team were interviewed retrospectively, among other things concerning their family circumstances. The study is interested in understanding two issues.

We suggest that leisure cross country skiers can also profit from a serious endurance capacity diagnostic. The aim of this study was to establish a reliable and valid protocol in order to make serious recommendation for training schedule of athleths. In order to analyze the relationship between endurance performance and the technic specific capabilities of cross country skiing aiming to allow valid recommendations participants had to absolve two test protocols. The first test consisted of detecting running pace on a treadmill at a 4 mmol/l blood lactate concentration. Second, participants had to absolve a Coopertest in skating technique on flat ground allowing to measure maximum distance absolved during 12 minutes and maximum heart rate.

This study aimed to investigate the relationship between the ability to perceive an Exertion quantified through BORG-Scale (6-20) and endurance level. Therefore 16 females and 28 males completed a lactate performance diagnostic as well as a 5000 meter course. Subjective Perception of effort was quantified according to BORG Scale (6-20). Participants were sex-divided and grouped in well endurance trained participants and not endurance trained participants. The analysis showed no clear differences between the two groups. Generally, lactate showed a closer correlative relationship with subjective perceived exertion than heart rate.

The intake of caffeine from tablets, coffee and energy drinks has shown to benefit endurance performance, whereas the effect of caffeine bars has not been investigated yet. Therefore, the aim of the study was to examine endurance performance, metabolism and perceived exertion following the co-ingestion of caffeine and carbohydrates in the form of bars.

Due to methodological and technical challenges brain cortical activity has rarely been investigated during endurance exercise. In this respect, it is not surprising that effects of an acute bout of interval training on central nervous activity have not been examined yet. Therefore, the aim of the present investigation was to characterize acute adaptations of brain cortical activity and established parameters to a high intensity endurance session. In a laboratory study sixteen endurance-trained cyclists completed an exercise bout including 3 interval series on a high-performance bicycle ergometer. Changes in cortical activity were recorded with quantitative electroencephalography (EEG) and analyzed in five specific frequency ranges (theta, alpha-1, alpha-2, beta-1, beta-2).

This paper highlights the findings of a comparative cross-sectional study in the cantons of Uri (UR) and Schwyz (SZ). In this study, participating in sports and daily physical activity among 5th grades were observed trough selected indicators. The study was conducted in autumn 2012 and 2013 and included a randomly selected sample of 161 pupils in Uri (10.6±0.7 year olds) and 261 pupils in the canton of Schwyz (10.7±0.7 year olds). In both regions, a high rate of participation in free time sports activities could be detected: 68.8% (UR) and 70.1% (SZ) of all the children involved are members of a sports club, with more than half of them, being active, both in and outside of sports club.

The aim of this study was to investigate differences in course times of a mountainmarathon (Napfmarathon) versus a city Marathon. Therefore all participants of Napfmarathon were screened concerning a double participation on a city marathon (Zürich, Winterthur, Lausanne, Luzern) and the course time were compared. Of key interest was the influence of ascents and descents which were quantified according to ­guidelines of Youth & Sport (Jugend + Sport / Jeunesse et Sport), whereby in first approximation 100 meter of ascent, 150 meter of descent (more than 20%) and 1 km of horizontal distance were taken as a simallar performance correlat.

Regular sports activity is not only healthy for cardiovascular and psychological reasons, but it is neither a risk factor for increased risk for osteoarthritis, except for posttraumatic osteoarthritis due to sports injuries. But there are few hints that excessice sports activity may lead to increased risk for osteoarthritis. Therefore, adapted and moderate sports activity can be recommended and should be promoted for osteoar­thritis or after total joint replacement of the lower extremity. This leads to increased functional and subjective outcome.

Eine «Low Energy Fraktur» ist das wichtigste klinische Symptom einer Osteoporose. Der ältere Sportler weist ein geringes Risiko für das Eintreten dieses Ereignisses auf. Die mit der sportlichen Aktivität verbundenen Stösse und Belastungen auf den Knochen wirken einem drohenden Abbau von Knochensubstanz nämlich entgegen. Sollte es im Rahmen der sportlichen Aktivität dennoch zur Fraktur kommen, dann entspricht der Unfallmechanismus in aller Regel nicht den Kriterien einer «Low Energy Fraktur».

In recent decades, increasingly greying societies have been noticed in industrialized nations. The rise in medical care necessary to manage the health of this aging population will ensue huge financial burdens on the healthcare system. The increase of age-specific diseases, compounded by declines in neuromuscular performance constitute two key reasons for a rise in the medical care of older people. Current scientific knowledge reveals that a consequence of aging is the loss of muscle mass and thus, a decrease in maximum and explosive strength.

Senior sportsmen and -women still participate in great numbers in sport events, particularly in endurance sports. Among the participants of the Jungfrau Marathon 2014 were 43% of the 3046 runners older than 50 years. These persons beeing active in sports have age related sportmedical problems. With four case reports the article tries to give concrete propositions to the sportsmed physician. Some of the graphics and tables are particularly appropriate for the counselling of active seniors in sports.

As a consequence of the demographically related increase of dementia prevalence, modifiable risk factors are gaining in importance as possible preventative measures. Medical treatment cannot yet heal dementia. The effects of vascular risk factors as well as behaviour and lifestyle changes on cognitive decline are the subject of a wide range of current literature. The role of physical activity has proved to be especially beneficial. Multiple studies with different study designs describe direct or indirect positive effects of physical activity on cognitive abilities. The positive effects of physical activity are particularly notable in cognitive domains such as attention or executive functions, which are often impaired in dementia.

Regular physical activity (PA) is a cornerstone of good health in the ageing population. Cardiorespiratory fitness is an important surrogate marker for survival. In primary cardiovascular disease prevention, PA is considered an effective mono­therapy with beneficial effects on the cardiovascular risk profile (e.g. lipid profile, blood pressure, diabetes mellitus, body composition) and endothelial function. In secondary prevention, PA is an addition to, rather than a replacement for evidence-based medication.
