Fred Paccaud, professeur d'épidémiologie et de santé publique (Lausanne), réagit à la campagne de dénigrement menée en avril 2008 contre le directeur de l'Office fédéral de la santé publique et les campagnes de prévention.

Position statement--altitude training for improving team-sport players' performance: current knowledge and unresolved issues.

Despite the limited research on the effects of altitude (or hypoxic) training interventions on team-sport performance, players from all around the world engaged in these sports are now using altitude training more than ever before. In March 2013, an Altitude Training and Team Sports conference was held in Doha, Qatar, to establish a forum of research and practical insights into this rapidly growing field. A round-table meeting in which the panellists engaged in focused discussions concluded this conference. This has resulted in the present position statement, designed to highlight some key issues raised during the debates and to integrate the ideas into a shared conceptual framework. The present signposting document has been developed for use by support teams (coaches, performance scientists, physicians, strength and conditioning staff) and other professionals who have an interest in the practical application of altitude training for team sports. After more than four decades of research, there is still no consensus on the optimal strategies to elicit the best results from altitude training in a team-sport population. However, there are some recommended strategies discussed in this position statement to adopt for improving the acclimatisation process when training/competing at altitude and for potentially enhancing sea-level performance. It is our hope that this information will be intriguing, balanced and, more importantly, stimulating to the point that it promotes constructive discussion and serves as a guide for future research aimed at advancing the bourgeoning body of knowledge in the area of altitude training for team sports.

Basic indicators for better governance in international sport (BIBGIS) : an assessment tool for international sport governing bodies

This working paper presents the Basic Indicators for Better Governance in International Sport (BIBGIS) as a tool to assess and measure the state of governance of international sport governing bodies. The working paper is organised as follows. We start by presenting different definitions of governance and some examples of principles of good governance in sport and critique them. We then introduce our approach which is based on a limited number of indicators divided among seven dimensions and apply it to the International Olympic Committee (IOC) and other international sport governing bodies. Although our approach can also be used to benchmark the governance of different sport organisations, we demonstrate that it faces limitations. We conclude with suggested next steps for future BIBGIS developments.

Human growth hormone doping in sport.

BACKGROUND AND OBJECTIVES: Recombinant human growth hormone (rhGH) has been on the list of forbidden substances since availability of its recombinant form improved in the early 1990s. Although its effectiveness in enhancing physical performance is still unproved, the compound is likely used for its potential anabolic effect on the muscle growth, and also in combination with other products (androgens, erythropoietin, etc.). The degree of similarity between the endogenous and the recombinant forms, the pulsatile secretion and marked interindividual variability makes detection of doping difficult. Two approaches proposed to overcome this problem are: the indirect method, which measures a combination of several factors in the biological cascade affected by administration of GH; and the direct method, which measures the difference between the circulating and the recombinant (represented by the unique 22 kD molecule) forms of GH. This article gives an overview of what is presently known about hGH in relation to sport. The available methods of detection are also evaluated. METHODS: Review of the literature on GH in relation to exercise, and its adverse effects and methods of detection when used for doping. RESULTS AND CONCLUSION: The main effects of exercise on hGH production and the use and effects of rhGH in athletes are discussed. Difficulties encountered by laboratories to prove misuse of this substance by both indirect and direct analyses are emphasised. The direct method currently seems to have the best reliability, even though the time window of detection is too short. hGH doping is a major challenge in the fight against doping. The effect of exercise on hGH and its short half-life are still presenting difficulties during doping analysis. To date the most promising method appears to be the direct approach utilising immunoassays.

Towards a sedentary society: trends in adolescent sport practice in Switzerland (1993-2002).

The rate of overweight and obese children and adolescents is rapidly increasing in developed countries. Although a decrease in sport practice may be one of the several factors implicated, data on recent trends are scarce. This article presents the trends in sport practice among Swiss adolescents between 1993 and 2002, comparing data from two surveys.
