Mätning av känslornas inverkan på golfspelares prestation med sensorteknologi (Swedish)
Abstract [en]

The impact of emotional states on athletic performance is a critical yet oftenoverlooked factor in high-level sports, where physical skills are often closelymatched. This research aimed to investigate whether providing golfers withreal-time feedback based on electrodermal activity (EDA) measurementscould improve performance by helping them regulate physiological arousalduring play.A wearable EDA sensor prototype was developed and tested on participants,using a voltage divider circuit that applied constant voltage to the skin. Acompanion app was developed in Flutter to provide feedback to users on bothiOS and Android devices. For post-processing, Python scripts wereimplemented using libraries such as SciPy, Pandas, and NeuroKit2.Statistical analysis included t-tests and Pearson correlation coefficients. Theonly variable that showed a statistically significant difference was the averagenumber of putts, suggesting that the device may help players become moreaware of their cognitive load. The Pearson correlation analysis indicated thatnone of the variables had a significant correlation. Although we successfullycreated a device and application capable of measuring arousal in real time,this project does not yet allow us to conclude whether feedback from thisbiosignal can positively impact golfers’ performance.

Abstract [sv]

Påverkan av känslotillstånd på idrottsprestationer är en avgörande men oftaförbisedd faktor inom elitidrott, där de fysiska färdigheterna ofta är jämntfördelade. Denna studie syftade till att undersöka om realtidsfeedbackbaserad på mätningar av elektrodermal aktivitet (EDA) kan förbättragolfspelares prestation genom att hjälpa dem att reglera fysiologiskupphetsning under spelet.En prototyp av en bärbar EDA-sensor utvecklades och testades på deltagare,med hjälp av en spänningsdelarkrets som applicerade en konstant spänningpå huden. En kompletterande applikation utvecklades i Flutter för att gefeedback till användare på både iOS- och Android-enheter. Förefterbearbetning implementerades Python-skript med bibliotek som SciPy,Pandas och NeuroKit2.Statistiska analysen inkluderade t-test och Pearson-korrelationskoefficienten.Den enda variabeln som visade en statistiskt signifikant skillnad var detgenomsnittliga antalet puttar, vilket antyder att enheten kan hjälpa spelareatt bli mer medvetna om sin kognitiva belastning. Pearson-analysenindikerade att ingen av variablerna hade en signifikant korrelation. Även omvi framgångsrikt utvecklade en enhet och en applikation som kan mätaupphetsning i realtid, tillåter detta projekt oss ännu inte att dra slutsatsen attfeedback från denna biosignal har en positiv inverkan på golfspelaresprestation.
