Consuming sports: distinction, univorism and omnivorism

The question of the social usages of culture and its links with social groups continues to be a topic of discussion today. The aim of this article is to contribute to the debate by examining coherence in the choice of physical activities and sports. The study focuses on the upper social groups, questioning, from a macro-sociological standpoint, their possible omnivority and their dissonance of choice with regard to these activities. Based on a quantitative survey of the sports participated in by the French, the study shows that omnivority and massification of activities are major phenomena. However, the upper social groups in France remain distinguishable both in terms of their "high level of omnivority" and their choice of distinctive activities. Dissonance is another of their characteristics but to a lesser extent.

Fatigue et réduction de la performance motrice chez le sportif, syndrome de surentraînement [Fatigue and reduction in motor performance in sportspeople or overtraining syndrome].

The main goal of training activities is to improve motor performance. After strenuous workouts, it is physiological to experience fatigue, which relieves within two weeks, and then induce an improvement in motor capacities. An overtraining syndrome is diagnosed when fatigue is postponed beyond two weeks, and affects mainly endurance athletes. It is a condition of chronic fatigue, underperformance and an increased vulnerability to infection leading to recurrent infections. The whole observed spectrum of symptoms is physiological, psychological, endocrinogical and immunological. All play a role in the failure to recover. Monitoring of athletes activities helps to prevent the syndrome with days with no sports. Rest, patience and empathy are the only ways of treatment options.

Pédiatrie [Pediatry].

During the previous year, several changes occurred in paediatric patient's management. The new PALS recommendations redefine the rhythm and the rate between cardiac massage and ventilation as well as the indications for defibrillation. The choice of the test for Helicobacter Pylori depends on the age of the patient and on the clinical situation. New anti-hypertensive drugs allow to limit the progression of chronic renal disease with hyper-tension and/or proteinuria. The choice between immunoglobulins, steroids, splenectomy and rituximab to treat chronic thrombocytopenic purpura treatment is a therapeutic challenge. Finally, a new approach is presented for diagnosis and treatment of iron overload in chronic hemoglobinopathies.
