Abstract

While repeating activities can create healthy habits, exploring new physical activities is also important to increase health benefits and prevent boredom. Following habit formation and variety-seeking behavior theories, this study investigates the difference between repetition and exploration of physical activities in health recommender systems. An eight-week Micro-Randomized Trial is conducted in which 11 physically inactive adults receive personalized activity recommendations that are either (a) a repetition or exploration, (b) connected to a specific location, duration, or neither, and (c) accompanied by videos or Points-of-Interest, or not. Analyses of the 187 submitted activity recommendations suggest that the inactive participants prefer exploration, as exploration recommendations were submitted the most, had significantly larger star ratings and durations, and are dependent on moderators (b) and (c). More specifically, exploration for workouts received the highest star ratings and motivation. To our knowledge, this study is the first to investigate repetition and exploration for physical activities, contributing to effective recommender algorithms for healthy behavior change.
