What type of attire is penalized in the gymnastics competition?

In gymnastics competitions, the attire worn by athletes is strictly regulated to ensure safety and maintain uniformity in appearance. Jewelry is penalized because it poses several risks. Firstly, it can be a safety hazard not only for the gymnast wearing it but also for others in the vicinity during routines. For example, rings, necklaces, or bracelets can catch on apparatus, leading to injuries or accidents. Additionally, jewelry can interfere with the gymnast's performance by causing distractions both to the gymnast and the judges.

In contrast, other attire options, such as leotards and shorts, are typically deemed appropriate for competition as they allow for full range of motion and do not present similar safety concerns. Sweatshirts might be worn before or after routines but are usually not acceptable competition attire due to the need for form-fitting clothing that showcases the gymnast's movements and body alignment. Thus, the prohibition against jewelry is specifically aimed at ensuring the safety and effectiveness of the athlete's performance.
