1, let's know the basic situation of the 400-meter dash. Due to the particularity of oval track, the length of inner and outer lanes is different. The outer channel is longer and the inner channel is shorter. This means that if every athlete starts from the same starting line, then the athletes in the inner lane run shorter, while the athletes in the outer lane need to run farther, which is obviously unfair.
2. In order to solve this unfair problem, the rules of the game introduced the system of "parting ways to start". This means that the starting position of each athlete is determined according to their time. Passes are randomly assigned before the game, usually decided by lottery or lottery system.
3. Starting in a separate lane also helps to reduce the risk of congestion and collision. In the early stage of the competition, the inner track athletes may try to squeeze to the outside quickly to avoid running more distances, which will lead to crowding and collision and endanger the safety of athletes. By starting on different runways, each athlete has enough space to start the race, thus reducing this risk.
4. Another consideration is angle. Athletes from the outside have a wider angle at the starting line than those from the inside, which helps them to better master the starting posture and speed. Insider athletes may need to face a sharp starting angle, which requires more skills and experience to deal with. Starting in separate lanes can balance this unfavorable situation to some extent.
