The term for a sudden change from one sport to another in competition is known as a "cross-sport transition." This phenomenon often occurs when an athlete, due to various reasons such as injury, retirement, or career change, decides to switch from their primary sport to another. It can highlight the athlete’s diverse skill set or adaptability, showcasing their abilities in different physical disciplines. Such transitions sometimes lead to unique success stories when the athlete excels in the new sport, gaining recognition and accolades.
