This case study examined how two rowers adapted their rowing patterns following crew training as a newly formed coxless pair. The two participants were expert (double-oar) single scull-boat rowers. Performing as a crew in the coxless-pair’s sweep-boat, where each rower operates a single oar, on-the-water data were collected before and after a 6-week intensive team-training program. Rowing patterns were characterized by the horizontal oar angle, oar angular velocity and linear oar-water velocity profiles during the catch (minimal oar angle) to finish (maximal oar angle) half-cycles of the propulsive water phase. After crew training, rowers demonstrated a tighter synchronization and a closer correspondence in oar angle at the moment of catch, together with a closer matching of the evolution over time of their subsequent oar movements. Most likely due to the inherent asymmetries involved in sweep-boat rowing, the stroke rower also developed a somewhat longer-duration larger-amplitude oar movement than the bow rower. Remarkably, both rowers revealed changes in the inter-cycle variability of their individual patterns of rowing. While the initially more variable stroke rower improved the consistency of his rowing pattern over practice, the initially highly consistent bow rower on the contrary relaxed his tendency to always perform in the same way. We discuss how the crew performance changed over training and to what extent it was associated with changes in individual behaviors. Along the way we demonstrate that the often-used measure of average continuous relative phase does not adequately capture the particularities of the coordination pattern observed. Overall, the results obtained at the individual level of analysis suggest that team benefits were obtained through distinct adaptations of the rowers’ individual rowing patterns.
L’objectif de cette étude est d’analyser la construction du partage au cours de la formation de jeunes footballeurs professionnels. Si l’identification des contenus partagés au sein d’équipes expertes est un objet de recherche bien documenté au sein du courant de la Team Cognition dans des équipes militaires, professionnelles ou sportives, peu d’études se sont intéressées à la construction du partage au sein d’équipe au cours d’une formation. L’approche théorique de la conscience collective de la situation a été mobilisée ici pour décrire l’évolution des contenus partagés au sein d’un collectif issu d’un centre de formation de football professionnel sur un empan temporel de 10 mois. Des données comportementales complétées par des données verbales, collectées lors d’entretiens d’auto-confrontation, sont recueillies et analysées en 4 étapes. Les résultats permettent de mettre en avant : (1) les contenus partagés pendant la formation, (2) l’évolution du taux des éléments partagés au cours de la formation et (3) l’évolution des contenus des connaissances partagées en cours de formation. Les résultats de cette étude sont discutés selon trois axes : (1) l’évolution du partage et la diminution des éléments « stables », (2) le partage de connaissances focalisées sur des éléments externes à l’équipe et (3) les apports méthodologiques pour l’étude de la conscience collective de la situation dans une perspective longitudinale.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
