Objectives: The objectives of this study were to observe the developmental trajectories of motivation types among young children from 8 to 12 years using a more comprehensive scale of physical education motivation. We also tested the relations between these trajectories and objective physical activity during this period.

Physical inactivity is a known risk factor for stroke. The interaction between exercise and risk of stroke is complex. Physical activity has a beneficial effect on most risk factors for stroke, which may show reciprocal potentiation (e.g. obesity, sleep apnea, atrial fibrillation). Advice on physical activity is of importance in primary prevention of stroke. Hereby, type, amount and intensity of physical activity may be distinguished and adjusted according to comorbidities (e.g. in case of heart failure).

There is a continuous increase in dementia partly due to increasing life-expectance. Currently there are no causal therapies for dementia, neither for dementias with vascular etiology nor for neurodegenerative dementias such as Alzheimer’s disease.
Main risk factors for the development of dementia are low physical activity, hypertonia and diabetes mellitus. Physical activity has shown to exert beneficial effects on cardiovascular and metabolic risk factors und is closely connected with cognitive disturbance and the development and the course of dementia.
Therefore, the implementation of physical activity in preventive and therapeutic strategies of dementia is recommended.

This case report presents the evolution of physiological and psychological health parameters of a former sedentary and physically inactive nursing student during an 18 months period (three academic semesters), during which she first took part to a one-semester institutional physical activity (PA) program offered by her University, before being selected to participate in relay to the Race Across America (RAAM) with a team of the University. The four months before the RAAM, she followed a cycling specific training program. After the RAAM, she was followed-up the next eight months.

After having a stroke the main challenges are reducing the risk of recurrent stroke, improving impaired brain function, quality of life, independence in activities of daily living and reintegration into the community. [1] Lesion-induced impairment of brain function also has, besides its effects on e.g. motor, sensory, visual and speech function, an influence on e.g. cognition and mood, all of which are determinants of post-stroke physical activity.
The evidence for a benefit of physical activity in secondary stroke prevention is increasing and treatment strategies aimed at factors which are limiting physical activity are more and more recognized.

Concentric and eccentric muscle work is characterized through different biochemical activating cascades. Concentric contraction is characterized by an ATP O2 coupling dependent interaction of the myofibril proteins Aktin and Myosin. In eccentric contraction, according to the Winding-filament hypothesis, a rotation movement around the thin filament is caused which is ATP independent. In addition, the processes of motor anticipation vary greatly between the two. This leads to the aim of the study: What are the differences in concentric versus eccentric muscle work concerning anticipation, perception and execution.

This observational study used field tests to investigate the association between physiological parameters and rowing performance in athletes during ergometer and on-water Swiss national competitions. 25 Participants between 15 and 35 years who compete at national level were recruited among different clubs. We assessed anthropometric parameters such as weight, height, aerobic capacity during an incremental test on a rowing ergometer, anaerobic capacity during an on rowing ergometer Wingate test and lower limb strength and power during countermovement- and squat jumps.

Background: Diffusion of information regarding ‘protecting athletes’ health’ and the ‘promotion of sport for health of the general population’ is a mission of National Sports Federations. Internet is a commonly used source of health-related information. The Olympic Games (OG) are an opportunity for a nation to promote the health benefits of sport.

The fight against doping is not primarily a fight against fallible athletes and coaches but rather a fight for clean athletes and coaches. Therefore, the present study aimed to investigate how Swiss athletes and coaches perceive the doping problem and the current anti-doping policy. Two online surveys of 1040 Swiss squad coaches and 588 Swiss athletes of various sports were conducted in 2016 and 2017. 41.5% of athletes and 31.5% of coaches identified a serious doping problem in their sport. This perception varied significantly by sport (p≤0.001). 94.2% of athletes and 91.7% of coaches argued in support of a strict prohibition of doping.

The Lausanne Youth Olympic Games in January 2020 represent a unique opportunity for the canton of Vaud to strengthen its policy of health promotion through physical activity and sport among young people. Several factors influence physical activity and physical fitness of a population. Ecological models describe correlates of physical activity in general population and youth. However, no model describes correlates of physical fitness. To close this gap, the model of physical fitness and its correlates among children and adolescents of the canton of Vaud (PACE model) was developed.

Meniscal Ramp lesions are frequently associated with Anterior Cruciate Ligament ruptures. It has been reported to play a key role in the anterior tibial translation the knee joint. Ramp lesions are difficult to diagnose in imaging modality and are under-recognized when using standard anterolateral and anteromedial arthroscopic portals even with probe test.
