Elite athletes of today use specialized, scientific training methods and the increasing role of science in sports is undeniable. Scientific methods and equipment has even found its way into the practice of everyday exercisers, a testament to the impact of sport science. From the experiential, personal training regimes of the first half of the 20th century to the scientific training theories of the 1970s, the ideas about training and the athletic body shifted. The rationalization process started in endurance sports in the 1940s. It was part of a struggle between two models of training; natural training and rational training. Physiologists wanted to rid training of individual and local variations and create a universal model of rational, scientific training. The rationalization of training and training landscapes is here understood as an aspect of sportification, a theory commonly used to describe similar developments in sports where increasing regimentation, specialization and rationalization are among the main criteria. This dissertation adds the concept of technologies of sportification to explain the role that micro-technologies and practices (such as training logs, training camps and scientific tests) have in the scientization of training. This thesis thus sets out to analyze the role that science has played in training during the 20th century. It is a history about the rationalization of training, but also about larger issues regarding the role of personal, experiential knowledge and scientific knowledge. The main conclusions are that the process of scientization never managed to rid training of components from natural, experiential training, and that the effort by Swedish physiologists to introduce rational training was part of the larger rationalization movement at the time. In the end, training knowledge was a co-production between practitioners and theoreticians, skiers and scientists. / <p>QC 20161114</p> / Rationell träning: vetenskapliggörandet äv träning för längdskidåkning

This thesis studies how scientists and science were put to use in the passing of the 1962 Water Fluoridation Act. The law was created for a specific purpose: that of facilitating the continuation of the water fluoridation trials that had been under way in Norrköping until January 1962, when they were forced to cease, having been deemed illegal by the Supreme Administrative Court.  By studying the network of scientists who were either directly involved in or explicitly supportive of the Norrköping trials, and their actions as members of the two expert committees formed in the 1950’s by the Royal Board of Medicine, and which would come to greatly influence the legislative process, the thesis examines how personal and research interests transferred from Norrköping into the issue of nationwide fluoridation.  Using analytical tools gathered from Roger Pielke Jr. and Daniel Sarewitz, the thesis utilizes the concept of uncertainty to describe how scientists, in the political process, assumed different roles in order to further the cause of fluoridation on the one hand, but also to maintain an ideal image of the relationship between science and politics. Furthermore, the tension within the concept of scientization is examined, illuminating how the political end result - the law - is made possible by means of a balancing act between science’s claims to objective truth and the value-driven, often ethically charged discourse of politics.   Fianlly, the case of fluoridation is placed in the context of the welfare state and the public health project, where it emerges as a part of a broader political and societal renegotiation of the relationship between the individual and the state, which I argue was taking place in Sweden during ”the long fifties”. / Uppsatsen studerar hur forskare och vetenskap kom till användning i skapandet av 1962 års Lag om tillsättande av fluor till vattenledningsvatten. Lagen kom till med ett specifikt syfte, nämligen att möjliggöra för en fortsättning av de försök med fluoridering av dricksvatten som hade pågått i Norrköping fram till januari 1962, då de tvingats att upphöra efter att ha bedömts som olagliga av Regeringsrätten.  Genom att studera det nätverk av forskare som knöts till Norrköpingsförsöken, antingen som direkt involverade eller som förespråkare, och hur dessa agerade som medlemmar av de två expertkommittéer som tillsattes av Medicinalstyrelsen för att utreda frågan om fluoranvändning i kariesförebyggande syfte, vilka kom att utöva ett betydande inflytande på lagstiftningsprocessen, undersöker uppsatsen hur forsknings- och personliga intressen överfördes från Norrköping till frågan om rikstäckande vattenfluoridering.  Med hjälp av analytiska verktyg hämtade från Roger Pielke Jr. och Daniel Sarewitz, tar uppsatsen fasta på begreppet osäkerhet för att beskriva hur forskarna i den politiska processen antog olika roller, i syfte att dels främja fluorideringen som sådan, men också att upprätthålla rådande ideal om relationen mellan vetenskap och politik. Vidare undersöks spänningen i den process som Roger Pielke kallar scientization, och hur det politiska slutresultatet - lagen - blev verklighet till följd av en balansgång mellan vetenskapens anspråk på objektiv sanning och politikens värderingsdrivna och ofta etiskt färgade diskurs.  Slutligen placeras fallet med vattenfluorideringen i välfärdsstatens och folkhälsoprojektets kontext, där det framträder som en del av en bredare politisk och samhällelig omförhandling av relationen mellan individ och samhälle, som jag menar ägde rum i Sverige under ”det långa femtiotalet”.
