Sammanfattning För den dubbelstakande längdåkaren är överansträngda muskler ett pågående problem. På uppdrag av Johnny Nilsson – lektor vid Gymnastik och Idrottshögskolan (GIH) i Stockholm – har en prototyp tagits fram för att övervaka överansträngning hos musculus trapezius (m. trapezius) med hjälp av elektromyografi (EMG). Prototypen kravspecificerades och projektgruppen fick uppdraget att med fria händer utveckla en rörelsereferens med mål att validera var i rörelsen som längdåkaren överanstränger muskeln. För att bygga elektromyografen användes den öppna hårdvaran Arduino som med EMG-modul kunde samla in data genom ytelektroder fästa på m. trapezius. För att uppfylla de funktionskrav som ställdes på rörelsereferensen byggdes en elektrogoniometer där en vridpotentiometer fästes på armbågsleden och mätte dess flexions- och extensionsvinkel. Arduinon programmerades genom dess egen programmeringsmiljö och ett SD-kort installerades på mikrokontrollerkortet för insamling av rådata; efterbehandlingen och presentation av data skedde sedan i Matlab. Med hjälp av Peter Arfert vid medicinsk bildteknik KTH designades ett 3D-utskrivet hölje till EMG-prototypen. Slutligen fick projektgruppen möjlighet att besöka LIVI-laboratoriet i Falun där längdåkning utövades på rullband. Studiebesöket gjorde det möjligt att praktiskt utföra testförsök av prototypen i dess tilltänkta testmiljö och samla in rådata. / Overwork of muscle can be a problem for the double poling cross country skier potentially resultingin lower efficiency. An assignment was established – on behalf of Johnny Nilsson at Gymnastik- ochIdrottshögskolan (GIH) in Stockholm – in order to build a prototype able to monitor and record datafrom musculus trapezius (m. trapezius) through the use of electromyography (EMG). The EMG wasmade using the open source hardware Arduino. The prototype was able to record bilateralmeasurements with the use of EMG-shields, where surface-electrodes were attached to m. trapezius.By creating a prototype based on a rotary potentiometer attached to the elbow joint a reference ofmovement was established by measuring the extension and flexion angle of the elbow. Arduino’s ownIDE was used to program the hardware of the prototype and data was post-processed and presented inMatlab. Data was transferred with the use of an SD-card reader installed on the microcontroller. Withthe help of Peter Arfert at KTH, a 3D-printed model was made for the prototype. The final prototypewas attached to an elite level cross-country skier and tested on a professional treadmill at the LIVIlaboratory in Falun, Sweden. Raw-data was successfully recorded during these trials.

The overall aim of this thesis is to analyze the presence of nationalism and patriotism in the live reporting of the 2019–2020 season of the FIS Cross-Country World Cup, reported by the Swedish national public service broadcaster, SVT. Thereby, the following research questions have been constructed: 1. Are patriotism and nationalism to be found in the live reporting by SVT of the 2019– 2020 season of the FIS Cross-Country World Cup? 2. If found, how is it manifested? The theoretical framework of this thesis consists of banal nationalism, patriotism, framing and us and them theory. The investigation has been limited to studying one of the several disciplines of cross country competitions. The material has been collected through ethnographic observations of the recordings online. For analysis, critical discourse analysis has been applied. The study shows a strong presence of both banal nationalism and patriotism in the live reporting of SVT. This can be concluded by the identified discursive and social practices in the text, such as discourses regarding justice and Swedish centrism. The results of this thesis are of importance for further comparative research projects of ideological reporting as well for sports media consumers to understand how ideology affects the reporting of a public service broadcaster.
