TY - THES U1 - Bachelor Thesis A1 - Brömme, Kevin T1 - Untersuchung von Einstellungsänderungen zu dem eigenen Sport- und Ernährungsverhalten durch die Nutzung von sozialen Netzwerken mit Bezug auf Alter und Geschlecht. N2 - Due to the rapid growth of the world wide web, and thus, the rapid growth of its relevance, there is an observable influence of its omnipresence on users of social networks and their behaviour. In the context of this bachelor thesis, the focus lies particularly on how social networks influence the perception of fitness and nutrition, which leads to a long-term changeof the behaviour of their users. This matter was investigated by classifying social media and its influence on users, followed by conducting an empiric study in form of a questionnaire, which allowed to make an educated guess towards the hypothesis.
