[Slices de gaucher versus droitier au badminton : rotation inverse du volant chiral et effet Magnus]
La nature chirale du volant de badminton est responsable de sa rotation antihoraire lorsqu’il se propage naturellement dans l’air. Cela induit une dissymétrie entre joueurs gauchers et droitiers et les trajectoires du volant qui en résultent, capturées en conditions réelles sur le terrain de badminton en slow motion à 3700 ips. Les vidéos mettent clairement en évidence cette dissymétrie puisque les slices effectués par les droitiers induisent une rotation antihoraire naturelle, tandis que ceux effectués par les gauchers induisent une rotation d’horaire à antihoraire, rendant les trajectoires de volants différentes. Les vidéos ont également mis en évidence un bref effet Magnus, souvent négligé au badminton, soulevant le volant pour les gauchers comme les droitiers et affectant l’efficacité du slice.
The chiral nature of a badminton shuttlecock is responsible for its counter-clockwise spinning as it naturally propagates through the air. This induces a dissymmetry between left- and right-handed players and the resulting trajectories of the shuttlecock, which were captured in real condition on the badminton court in slow motion at 3700 fps. The videos clearly evidence this dissymmetry as slice shots performed by right-handers induce a natural counter-clockwise spinning, while the ones performed by left-handers induce a clockwise to counter-clockwise spinning, making trajectories of shuttlecocks different. The slow motion videos also caught a brief Magnus effect, often neglected in badminton, lifting up the shuttlecock for both left-handers and left-handers and affecting the effectiveness of the slice shot.
