Relay materials, in different contexts, can refer to essential elements or devices involved in the transmission of forces, energy, or data. These materials play a vital role in both physical sports and engineering applications, where their function and quality are crucial to performance and reliability. In this article, we will explore relay materials in two main areas： athletics and electrical engineering, and discuss their significance in these domains.

Relay Materials in Sports In the world of sports, particularly in relay races, “relay materials” most commonly refer to the relay baton or relay stick used in track and field events. A relay race is a team competition in which runners pass a baton to the next runner in a designated exchange zone. The baton, often a cylindrical rod, serves as the “relay material” and is one of the most critical aspects of the event. The design and materials used for making the baton influence how efficiently it can be exchanged between team members, affecting overall performance. Relay batons are typically made from materials like aluminum, plastic, or carbon fiber. Aluminum batons are lightweight and durable, which allows athletes to maintain high speeds while ensuring the baton does not break during the exchange. Some high-performance batons are made from carbon fiber, which provides even greater durability and lighter weight, giving athletes an edge in speed and maneuverability. In elite competitions, the weight and balance of the baton are strictly regulated, ensuring fairness and consistency across all competitors.
