Performance analysis in orienteering with consideration of both cognitive and physical aspects

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.

Epidemiology and prevention of injuries in young sportsmen. A 35 year observational study of the sport and art classes in the Canton of Geneva

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.

Effects of cold water immersion or contrast on post-exercise recovery in acyclical sports : a systematic review and meta-analysis

Introduction: Les différentes techniques d’immersion, en eau froide ou en eau contrastée représentent un fort intérêt pour les sportifs afin d’optimiser leur récupération. Un manque de consensus existe quant aux effets de ces modalités de récupération. Objectif: évaluer les effets des deux interventions à 24 heures post effort musculaire dans les sports acycliques. Méthode: revue systématique et méta-analyse. Quatre bases de données explorées (Pubmed, Cinahl, Web of Science, Cochrane). Indicateurs observés: courbatures (DOMS: Delayed onset Muscle Soreness), créatine kinase (CK), et capacités fonctionnelles.

The influence of familial factors on the development of young football players to elite level

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.

New findings in performance diagnostics for amateur cross-country skiers

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.

Caffein bars pre time trial improve performance and reduce perceived effort

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.

Mountain vs city marathon: a discussion around the concept of effort and kilometers

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.

The elderly athlete in the sports medicine consultation

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.

Psycho-educational group discussions: effective tool to reduce overload in adolescents facing a dual career challenge in sports/arts and studies?

Pendant les années 2011–2013, 151 jeunes talents sportifs et artistes du programme pour talents sportifs et artistiques du Canton du Tessin («Programme pour talents SMS») ont participé à un projet de suivi de leur santé sur le plan psychologique. Les objectifs visés par ce projet étaient l’évaluation du risque de surcharge psychologique de la population observée et le test de l’efficacité d’une intervention psycho-éducative de groupe pour réduire ce risque. Les jeunes talents – subdivisés en un groupe intervention (n=28) et un groupe contrôle (n=123) – ont rempli un questionnaire d’entrée (PRE), mesurant les paramètres psychologiques tels que l’anxiété, les motivations intrinsèques, ainsi que quatre facteurs de burnout et la perception d’un conflit d’intérêt entre pratique sportive/artistique et études. 8 mois après, ils ont été à nouveau interrogés au moyen du même questionnaire (POST), complété par des questions d’évaluation finale. Les réponses aux questionnaires d’entrée ont permis de montrer que 57.6% de l’ensemble des jeunes talents sont potentiellement à risque de surcharge psychologique.

Validation of an electronic jumping ability measurement device for handball specific jumps

The aim of this study was to examine the validity of the electronic jump measurement system Training TesterTM to measure team handball specific jump performance. For this reason, standing reach height and team handball jump specific reach height were determined simultaneously with the Training TesterTM and a motion capture system as criterion measure. The Training TesterTM slightly underestimated the variables of interest. This can be explained by the relative small measuring zone of the Training TesterTM in comparison to the motion capture system. However, the correlation coefficients between both measurement methods were found to be very high.
