Practical-theoretical approaches formulate novel theoretical and empirical-analytical perspectives and have gained increasing attention in the social and cultural sciences in recent years. The blurring of epistemological oppositions that continue to divide the social sciences, as well as an empirically oriented and methodologically focused understanding of theory, are their main characteristics. Robert Schmidt applies these concepts in various research contexts from the fields of sports (handball, inline hockey, triathlon) and the working world (in a software development office). This leads to dynamic constellations that demonstrate the effectiveness of a sociology of practices.
