The sport that utilizes a circular rotating device called a discus is track and field. In this event, athletes throw the discus, a disc-shaped object, for distance. The discus throw is a traditional Olympic event that requires a combination of strength, technique, and rotational power. Competitors take turns throwing the discus from a circular ring, aiming to achieve the longest throw possible. Successful throws depend on the athlete's ability to harness their technique and body mechanics, making it both a physical and technical challenge.
