This study explored interpersonal coordination on artistic swimming teams by focusing on how swimmers interact with their environment when they adjust their movements to each other. This competitive context has never been investigated and we expected that the swimmers’ interpersonal coordination would provide new insights into the coordination of their activities during team performances. Ten swimmers volunteered to participate in the analysis of national or international competitions. The method was based on individual enactive interviews designed to grasp swimmers’ activity as they adjusted to each other. Through an inductive content analysis, five meaningful interactions were identified, with: (a) the 8-counts, (b) the activity of other swimmers, (c) key moments in the music, (d) their own sensations, and (e) the material environment. The results revealed how the swimmers’ activity was developed from different types of information that enabled them to make sense of the movements underway to achieve team performance.
