The Olympic sport involving a pole and a bar is pole vaulting. In this track and field event, athletes use a long, flexible pole to propel themselves over a high bar. The goal is to clear the bar without knocking it down, demonstrating a combination of speed, strength, and technique. Pole vaulting has a rich history in the Olympics, with athletes competing in various heights. The sport requires rigorous training, and competitors often display impressive acrobatics as they soar through the air before landing safely in a padded area.
