No contestant shall wrestle in two consecutive matches with less than a ____________ rest between them.

In wrestling, the guidelines for rest periods between matches are crucial for ensuring the health and safety of the athletes. A 45-minute rest period is mandated to allow wrestlers adequate time to recover physically and mentally between matches. This rest period helps to reduce the risk of injury and fatigue, ensuring that competitors are at their best when they take to the mat again.

Wrestling is a physically demanding sport that requires high levels of strength, endurance, and concentration. Without a proper recovery time, athletes may not only perform poorly but could also face greater chances of overexertion, dehydration, or injuries. Therefore, the regulation specifying a minimum of 45 minutes of rest serves to promote fair competition and athlete welfare, allowing each contestant adequate time to prepare for their next bout.

The other potential answers do not provide the correct time frame according to the established rules, which prioritize athlete safety and performance standards.
