Appropriate alternatives to the 1-RM strength test are multiple repetition maximum strength tests, particularly considering recreational sports. In contrast to the 1-RM strength test, limited research of multiple repetition maximum strength tests has been conducted and thus causes a shortage of standardized and evaluated test protocols. Therefore, the aim of this study was to evaluate the validity of a 5-repetition maximum strength test, which excellent reliability was already confirmed, for the purposes of performance assessment and training control in recreational sports. Twenty-six healthy recreational athletes (25.9 ± 3.4 years;181.2 ± 5.1 cm;79.4 ± 8.7 kg) with at least one year experience of strength training completed two examinations, which implied a bench press exercise. In examination one, the 5-RM and the 1-RM was determined.

The diagnostic protocol presented here allows orienteers to compare themselves to others in the sample and to analyse the proportion of physical and technical skills in their overall performance. In order to test the protocol 3 female and 11 male leisure athletes completed two short orienteering courses, one with four control points (distance 0.80 km, altitude 5 m) and one with eight (distance 1.95 km, altitude 40 m). The average running time was 6 min and 40 sec (± 2 min 18 sec) on the short and 17 min 36 sec (5 min ± 1 sec) on the long course when orienteering. After courses were marked with the optimum route running times decreased, as expected, to 3 min 45 sec (± 48 sec) on the short and 9 min 21 sec (± 1 min 19 sec) on the long course.

Physical activity is recognized as a basic component of the management of the obese child, but it is not clear which kind of intervention is the most efficient. The aim of this study is to evaluate the effect of prescribed exercise training in obese children. We reviewed 19 studies, 10 RCT and 9 observational studies, published in the last 5 years. In the majority of these studies obese children were treated as ambulatory patient, in tertiary centers. Only 2 studies described a community based program. In half of the studies, drop-out was not reported and the rate of attendance was rarely described. On the other hand, the content of each session was well described, but exercise training intensity was below international recommendations.

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.

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.
