Adolescence is triggered by puberty and corresponds to a time of great changes in many fields including biological, psychological, cognitive and social. Participation to a sport activity improves self-esteem, socialisation with peers and physical condition. Yet, it sometimes is associated with suffering, restrictive behaviours and eating disorders when performed at an intensive level. Intensive sport activity during adolescence should take into account young people’s developmental stages as well as their fundamental needs in order to promote a harmonious training. One way to promote such training is to train parents and medical health providers to recognise these specific developmental needs and take them into account.

Sports-related concussion in young athletes is a major issue in sports medicine. Although it attracts a lot of media attention, at the same time it suffers from insufficient spread of the knowledge regarding its identification and the adequate protocols to be implemented in the return to sport sequence. Underreporting and trivialization of potential concussions is too frequent, although it can have serious consequences, ranging from an increase in repeat concussion or second impact syndrome, to academic difficulties and persistence of cognitive or physical symptoms.

Injury prevention is a priority in the field of sports medicine and in physical activity promotion, in particular for youth. Injuries can lead to long term handicaps and disengagement from physical activity. The follow up of young sportsmen in the canton of Geneva over the last 35 years has permitted to get an idea of the prevalence of injuries in young sportsmen and allows a comparison with the general population. It has also permitted to get an idea of the influence prevention has had on injuries.

Objectives: To evaluate the responsiveness of the classic Star Excursion Balance Test (SEBT) and of a modified version performed on a soft surface (Airex Balance-Pad). The classic Star Excursion Balance Test is widely used in persons with chronic ankle instability. For the use in healthy athletes, the test can be made more difficult by performing it on a soft surface.
Design: Pre-post study with balance assessment before and after a five-week intervention.
Setting and participants: A convenience sample of 28 healthy adults performed both SEBT variants at baseline and after five weeks (9 sessions) of sensorimotor and strength training.

Femoroacetabular impingement (FAI) is a pathomechanical process of the hip, which can occur in every individual but has a higher prevalence in physically active subjects such as athletes. It is mainly due to bony deformities at the proximal femur and/or acetabulum in conjunction with rigorous or supraphysiological hip ranges of motion. FAI may lead to chondrolabral lesions, hip pain and development of early hip osteoarthritis. Symptomatic FAI patients may present functional limitations during daily activities and sports, reduced hip muscle strength as well as hip joint kinematic and kinetic alterations during weight-bearing activities.

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.

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).
