What is the role of weigh-ins before a match?

Weigh-ins serve a crucial function in wrestling by ensuring that each competitor falls within the designated weight class for their upcoming match. This is vital for maintaining fairness and safety in wrestling competitions. Each wrestler registers a weight before competing, which helps to prevent mismatches in size and strength that could lead to injury or an unfair advantage. By verifying that athletes meet the weight requirements, the integrity of the competition is upheld, and it promotes a level playing field where skills and techniques, rather than size, play a more significant role in the performance outcomes.

The other options, while they may touch on aspects related to competition, do not capture the primary purpose of weigh-ins. Strength assessments or evaluations of physical condition are not typically part of the weigh-in process, nor is scheduling established at this time. Instead, the core objective is centered purely around weight classification for fairness in the sport.
