Our conviction rooted in our own research and the work of others in the field. We believe that moving research from the confines of the laboratory into real-world settings offers immense potential for gaining valuable insights and advancing knowledge in the realms of physical activity, sports, and exercise. Ambulatory Assessment can be applied in a wide range of subfields such as sport and exercise psychology, biomechanics, sports sociology, training science, and many more. Despite this diversity, these research areas share a common focus on situational-specific factors, time-, space-, & and dependent variations, context-dependent variations, and the distinction between within-subject and between-subject varianceindividual processes.

Our areas of interest are as diverse as our questions, ranging from “How does motivation fluctuate throughout the day, and how are specific contextual factors associated with this variation?” to “How do volleyball players’ jump heights change over the course of a season, and how are they influenced by specific ‘in-the-moment’ interventions such as mental training?” Additionally, we explore apparent paradoxes, such as stressed individuals generally exercising less, while those feeling stressed in the moment might exercise more on a given day.
