The aim of the study was to examine the temporal relationship between facets of sport-specific dispositional mindfulness (i e., Awareness, Refocusing, Nonjudgemental attitude) and shooting performance in actual competitions, in a population of 25 elite biathlon athletes. Findings indicated that mindfulness facets were positively associated with shooting performance, with higher levels of Awareness, Refocusing, and Awareness being related to better shooting performance in competitions. In spite of the fact that the explained variance was quite small, even a minor shooting performance enhancement may increase an athlete's chance of winning a biathlon competition.
