This article is written from the perspective of Josef Šmajs’ evolutionary ontology and considers physical activity in humans. It focuses in detail on a particular form-physical exercise. In the author’s opinion, current physical exercise (sport activity) and any other human form of activity is part of the internal autopoietic processes of the sociocultural system, which displays an ever-increasingly destructive tendency towards its natural environment-towards the host system of the biosphere. The author attempts to establish the degree and manner to which the anti-nature activity of physical exercise varies, but also seeks to point out how they contribute to a potential biophilic transformation of culture.
