Detection of nandrolone metabolites in urine after a football game in professional and amateur players: a Bayesian comparison.

Nandrolone (19-nortestosterone) is a widely used anabolic steroid in sports where strength plays an essential role. Once nandrolone has been metabolised, two major metabolites are excreted in urine, 19-norandrosterone (NA) and 19-noretiocholanolone (NE). In 1997, in France, quite a few sportsmen had concentrations of 19-norandrosterone very close to the IOC cut off limit (2ng/ml). At that time, a debate took place about the capability of the human male body to produce by itself these metabolites without any intake of nandrolone or related compounds. The International Football Federation (FIFA) was very concerned with this problematic, especially because the World Cup was about to start in France. In this respect, a statistical study was held with all football players from the first and second divisions of the Swiss Football National League. All players gave a urine sample after effort and around 6% of them showed traces of 19-norandrosterone. These results were compared with amateur football players (control group) and around 6% of them had very small amounts of 19-norandrosterone and/or 19-noretiocholanolone in urine after effort, whereas none of them had detectable traces of one or the other metabolite before effort. The origin of these compounds in urine after a strenuous physical activity is still unknown, but three hypotheses can be put forward. First, an endogenous production of nandrolone metabolites takes place. Second, nandrolone metabolites are released from the fatty tissues after an intake of nandrolone, some related compounds or some contaminated nutritive supplements. Finally, the sportsmen may have taken something during or just before the football game.

Le football, ses dieux et ses démons. Menaces et atouts d'un jeu déréglé

Cet essai sur le football est un livre foisonnant sur le sport le plus populaire de l'humanité. Ethicien, théologien et fervent supporter, Denis Müller est un passionné du foot dont il suit les moindres péripéties locales ou internationales depuis plus de 50 ans. Considéré comme l'un des deux ou trois meilleurs intellectuels réfléchissant à ce sport dans l'aire francophone, il intervient souvent dans les médias pour analyser avec recul et empathie un phénomène qui dépasse parfois l'entendement. Régulièrement sollicité pour écrire un ouvrage sur le foot, Denis Müller relève enfin ce défi et de la plus belle manière. Mêlant souvenirs personnels, considérations éthiques, sociologiques ou théologiques, étudiant l'évolution du foot pour en identifier les perversions et les promesses, Denis Müller aborde tour à tour son histoire, ses règles, le fanatisme, le rapport des femmes à ce sport, l'arbitrage, le dopage ou encore les affaires. Mais ce livre est aussi un hymne, un éloge enthousiaste et lucide à une activité significative de notre modernité collective.

African migrants in Asian and European football: hopes and realities

This paper analyses the integration of Africa in the global labour market of football through the study of players' migrations to Asia and Europe. The presence of African footballers in the latter continent is analysed via a statistical survey carried out in September and October 2008 on a sample of 456 top division clubs in 30 European countries. The article emphasizes that the aspirations placed on football by male African youth, as a means of upward social mobility, are often too high when compared to the harsh realities of a transfer market based on commercial logics, which each year push many footballers away from the professional game.

A one-year monitoring of nicotine use in sport: frontier between potential performance enhancement and addiction issues

Tobacco consumption is a global epidemic responsible for a vast burden of disease. With pharmacological properties sought-after by consumers and responsible for addiction issues, nicotine is the main reason of this phenomenon. Accordingly, smokeless tobacco products are of growing popularity in sport owing to potential performance enhancing properties and absence of adverse effects on the respiratory system. Nevertheless, nicotine does not appear on the 2011 World Anti-Doping Agency (WADA) Prohibited List or Monitoring Program by lack of a comprehensive large-scale prevalence survey. Thus, this work describes a one-year monitoring study on urine specimens from professional athletes of different disciplines covering 2010 and 2011. A method for the detection and quantification of nicotine, its major metabolites (cotinine, trans-3-hydroxycotinine, nicotine-N′-oxide and cotinine-N-oxide) and minor tobacco alkaloids (anabasine, anatabine and nornicotine) was developed, relying on ultra-high pressure liquid chromatography coupled to triple quadrupole mass spectrometry (UHPLC-TQ-MS/MS). A simple and fast dilute-and-shoot sample treatment was performed, followed by hydrophilic interaction chromatography-tandem mass spectrometry (HILIC-MS/MS) operated in positive electrospray ionization (ESI) mode with multiple reaction monitoring (MRM) data acquisition. After method validation, assessing the prevalence of nicotine consumption in sport involved analysis of 2185 urine samples, accounting for 43 different sports. Concentrations distribution of major nicotine metabolites, minor nicotine metabolites and tobacco alkaloids ranged from 10 (LLOQ) to 32,223, 6670 and 538 ng/mL, respectively. Compounds of interest were detected in trace levels in 23.0% of urine specimens, with concentration levels corresponding to an exposure within the last three days for 18.3% of samples. Likewise, hypothesizing conservative concentration limits for active nicotine consumption prior and/or during sport practice (50 ng/mL for nicotine, cotinine and trans-3-hydroxycotinine and 25 ng/mL for nicotine-N′-oxide, cotinine-N-oxide, anabasine, anatabine and nornicotine) revealed a prevalence of 15.3% amongst athletes. While this number may appear lower than the worldwide smoking prevalence of around 25%, focusing the study on selected sports highlighted more alarming findings. Indeed, active nicotine consumption in ice hockey, skiing, biathlon, bobsleigh, skating, football, basketball, volleyball, rugby, American football, wrestling and gymnastics was found to range between 19.0 and 55.6%. Therefore, considering the adverse effects of smoking on the respiratory tract and numerous health threats detrimental to sport practice at top level, likelihood of smokeless tobacco consumption for performance enhancement is greatly supported.

Le football comme religion populaire et comme culture mondialisée : brèves notations en vue d'une interprétation critique d'une quasi-religion contemporaine

(Résumé de l'ouvrage) Le présent recueil d'hommages veut témoigner de l'importance de l'oeuvre théologique de Jean Richard, professeur à la Faculté de théologie et de sciences religieuses de l'Université Laval. Désireux de signifier leur reconnaissance au père Richard, les auteurs de ce livre ont proposé des textes s'inscrivant dans l'un ou l'autre de ses champs de recherche privilégiés. Le tableau des contributeurs à ces mélanges regroupe des théologiens de tous les âges, hommes et femmes, provenant du Canada, mais aussi des États-Unis et de l'Europe, de langue française, anglaise ou allemande, de confession catholique ou protestante, oeuvrant dans des champs disciplinaires aussi divers que la théologie systématique, la théologie fondamentale, l'éthique théologique, l'exégèse ou encore la philosophie. Cette diversité est révélatrice de la personnalité théologique du père Richard, du caractère international de son réseau d'amitiés et de recherche et de l'ampleur de son influence. Elle témoigne aussi de l'audace d'une oeuvre qui, entreprise dans les années 1960, a dès le départ relevé le défi de l'aggiornamento que venait de poser en toute urgence son Église et qui a très vite conduit son auteur « aux confins », pour reprendre - et pour cause - une expression de son mentor Paul Tillich qui lui sied à merveille. Les contributions réunies dans ce volume ne résultent pas d'un plan concerté. D'autant plus significatifs sont les recoupements thématiques qu'on y observe, qui, par un hasard seulement apparent, restituent les principaux axes de la production théologique du père Jean Richard. L'ouverture au présent et a ses problématiques propres, ainsi que les défis conceptuels par là posés à l'effort théologique constituent les deux constantes de ces contributions, comme de l'oeuvre qui les a inspirées.

«Où, quand, et comment ?» : Évolution des conduites agressives en football et en hockey sur glace

RésuméCette étude a pour objectif d'observer l'évolution des actes agressifs dans deux sports d'équipes en fonction de facteurs situationnels (périodes de jeu, lieu de la faute, état du score) et du type d'agressions (instrumentales, hostile). 60 matchs professionnels de football et de hockey sur glace ont été filmés puis analysés à l'aide de grilles d'observation différenciant les deux types d'agressions. Les résultats révèlent que dans ces deux sports, les agressions instrumentales sont plus fréquentes dans les zones importantes du terrain (milieu ou défense) ou lorsque le score est serré. En revanche, les agressions hostiles ne varient pas (ou peu) selon ces facteurs. Les résultats sont discutés au regard de la théorie de l'apprentissage social et de l'hypothèse frustration-agression.AbstractThis study aims at examining observed aggression in two team sports as a function of situational triggers (periods, zones of field, games score) and of type of aggression (instrumental, hostile). 60 soccer and ice hockey games were recorded and analyzed using a grid that differentiates the two types of aggression. The results revealed that theses two sports, instrumental aggressions were more frequent in important zones of field (neutral or defensive ones) and in tied score situations. However, no difference was found for hostile aggression according to these factors. The discussion focused on the social learning theory and frustration-aggression hypothesis.
