This dissertation focuses on the digital presentation of athletification, a process through which non-athletes incorporate an athletic identity into their self-concept. Although many studies have explored consumer behavior driven by team identification and how athletes manage impressions on social media, extant literature has devoted little attention to the symbolic meaning of virtual athletic identity and its impact on consumption from a non-athlete’s perspective. Using a multimethod approach, this dissertation is divided into three standalone essays and examines the following in the context of influencer marketing: 1) the use and role of digital athletic identity in building a digital self-brand; 2) the motivation and consequences of constructing a digital identity; and 3) the impact of a digital athletic identity on consumers. This dissertation contributes to the literature by constructing a theoretical foundation for athletification as a self-branding tool on social media and uncovering its influence on consumers’ attitudes and behaviors. These studies offer insights for social media influencers and marketers attempting to leverage their impacts on consumers. Findings also provide actionable strategies that could improve the promotional messages presented online. / Tourism and Sport
