Longevity and causes of mortality in elite athletes / Longévité et causes de mortalité de l’élite sportiveAntero-Jacquemin, Juliana 16 November 2015 (has links)
Cette thèse a démontré que les athlètes élites vivent en moyenne 7 ans de plus que la population générale, notamment en raison d’une réduction de 35 à 45% de la mortalité par maladies cardiovasculaires et par cancers. Ces résultats s’appuient sur l’analyse de l’ensemble des sportifs français (n= 3.600) ayant participé aux Jeux Olympiques depuis 1912 et au Tour de France depuis 1947. Des nouvelles méthodes en analyse de survie ont été mises au point pour investiguer ces cohortes qui ont la particularité de survivre mieux que leurs référents. A ces démonstrations s’ajoute le ralentissement de la progression de la longévité maximale humaine. Ce constat résulte de la comparaison des tendances de durée de vie de tous les olympiens depuis 1896 (n= 19.012) et des doyens de l’humanité (n= 1.205). Ces travaux répondent au besoin de mieux comprendre la relation dose-réponse de l’activité physique, médicament du 21ème siècle, en raison de son impact majeur sur la longévité des populations, ainsi qu’à l’intérêt d’explorer les marges d’augmentation possibles de cette longévité. / Background and objectives: along their careers, elite athletes are subjected to specific constraints that distinguish them from the general population. Such constraints, related to the high intensity of their physical activity, their overexposure to injuries or particular lifestyle, may have long-term consequences on the athletes' health, and ultimately on their longevity. Thus, the main goals of the present study are the following: 1) to describe and analyze elite athletes’ longevity and specific causes of mortality in comparison with the general population and according to the type of effort they performed; and 2) to investigate their lifespan trends in comparison with the longest-lived humans in order to apprehend the current scenario of human longevity trends. Methods: we collected data on the biography and the athletic performances of all the French athletes who participated in the Olympic Games (OG) from 1912 to 2012 (n = 4708), and all the French cyclists who participated in the Tour de France (TDF) from 1947 to 2012 (n=786). Then, we verified their vital statuses through the National Registry of Identification of Physical Persons (RNIPP). For the deceased athletes, we obtained the causes of their deaths through the Centre for epidemiology on medical causes of death (CépiDc). We compared the athletes’ overall and specific mortality (according to the main chapters of the International Classification of Disease) with the French civilian life tables using Standardized Mortality Ratio (SMR) and the Kaplan-Meier methods. We adapted and applied the life years-lost method under the competing risk model to quantify differences on longevity due to major causes of death according to the athletes’ type of effort. Furthermore, we collected data on worldwide deceased Olympians participating in the OG from 1896 to 2012 (n=19 012) and on worldwide supercentenarians (>110 years) deceased between 1900 and 2013 (n= 1 205) in order to analyze their lifespan trends using a density analysis tool (total number of life durations per birth date). Findings and conclusion: French elite athletes show consistently lower mortality (≈40-50% lower) in comparison with their compatriots, whether female or male Olympians, or professional cyclists, mostly related with a lower cardiovascular (≈ 40-60% lower) and cancer mortality (≈ 45% lower). No excess mortality was observed in elite athletes for any of the specific causes of death we studied. French Olympians’ lower mortality results in an average of seven years of life saved in relation to the general population. This gain partitioned according to specific causes of deaths shows that cardiovascular longevity benefit is associated with the type of sports practiced during the Olympic career, favoring combined type of effort over very short- or very long-duration effort. In relation to cancer mortality, all types of effort studied were associated with better longevity. Despite their survival advantage, no Olympian in the world, up to date, has ever reached the status of a supercentenarian, as the longest-lived was 106 years old. The common lifespan trends between Olympians and supercentenarians indicate similar mortality pressures over both populations that increase with age, a scenario that is better explained by a biological “barrier” limiting further progression. The supercentenarians’ density trends show a current stagnation of the human longevity.

Technik und Bildung in der verwissenschaftlichten LebensweltLumila, Minna 02 June 2023 (has links)
Die Studie versucht, Husserls Modell einer nicht-wissenschaftlichen Lebenswelt für pädagogische Untersuchungen zum Verhältnis von Technik und Bildung in der verwissenschaftlichen Welt zu öffnen. Sie diskutiert Entwicklungsprobleme der Spätmoderne unter pluralen Fragestellungen und führt Ansätze und Traditionen zusammen, die unterschiedliche Wege zur Weiterentwicklung der modernen Bildungstheorie beschritten haben. Im Zentrum steht die Frage, wie moderne Technik einerseits als lebensweltliche Entfremdung des Menschen problematisiert und andererseits als Produkt menschlicher Freiheit und Weltgestaltung gewürdigt werden kann. In vier Kapiteln werden die methodischen Ansätze und Antworten vorgestellt, die der Philosoph und Pädagoge Eugen Fink (1905–1975), der Philosoph Martin Heidegger (1889–1976), der Philosoph und Erziehungswissenschaftler Theodor Litt (1880–1962) und der Soziologe Helmut Schelsky (1912–1984) auf die Frage nach dem Verhältnis von Bildung und Technik gegeben haben. Im Durchgang durch ihre Positionen wird ein Konzert erarbeitet, dessen Originalität darin liegt, Abstimmungsprobleme von Bildung, Technik und Lebenswelt aus postdualistischer, praxistheoretischer sowie posthumanistischer Perspektive zu thematisieren. / The study attempts to open Husserl's model of a non-scientific lifeworld for pedagogical investigations of the relationship between technology and “Bildung” in the scientific world. It discusses developmental problems of late modernity under plural questions and brings together approaches and traditions that have taken different paths to the further development of modern “Bildungs”-theory. The central question is how modern technology can be problematized on the one hand as the alienation of human beings from the world of life and on the other hand be appreciated as a product of human freedom and the shaping of the world. Four chapters present the methodological approaches and answers that philosopher and educator Eugen Fink (1905–1975), philosopher Martin Heidegger (1889–1976), philosopher and educationalist Theodor Litt (1880–1962), and sociologist Helmut Schelsky (1912–1984) have given to the question of the relationship between education and technology. In the course of their positions, a concert will be developed whose originality lies in addressing the coordination problems of “Bildung” (education), “Technik” (technology) and “Lebenswelt” (lifeworld) from a post-dualist, praxis-theoretical as well as post-humanist perspective.
