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.

Objective: The objective of the project is to actively integrate students partially dispensed from school sport through an adapted form of sports dispensation as well as a customized selection of exercises. Method: By means of two online questionnaires, both structured similarly with respect to questions and main themes, a needs assessment was carried out. The questionnaires were sent by e-mail to 2600 members of three Swiss medical associations, doctors of the University Children’s hospital of Basel as well as to approximately 4000 sports teachers of the Swiss organization for sports at school.

Purpose: Comparison of surgical techniques by evaluating functional capacities: power, strength, velocity and dynamic stability of knee extensor and flexor muscles after ACL reconstruction. Material and Methods: a prospective study with a retrospective comparative cohort of 111 patients (mean age 30 years (14.4 - 49.7). Outcomes: 18 outcomes were considered. Objective outcomes were the difference of power, strength, velocity and dynamic stability. Subjective outcomes included Tegner activity scale, Lysholm score, KOS, KOS-SAS (Knee Outcome Survey-Sport Activities Score), Tampa scale-Q.

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.

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.

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.
