Which activity is prohibited during weigh-ins?

The correct choice focuses on activities that promote dehydration. During weigh-ins, the primary concern is ensuring that all wrestlers are attempting to meet their designated weight class in a fair and healthy manner. Engaging in activities that could cause dehydration, such as excessive sweating or other methods to lose weight quickly, can compromise the integrity of the competition and put the wrestler's health at risk.

Maintaining health and safety standards is crucial in sport, particularly in wrestling, where weight classes play a significant role in competition. Allowing actions that induce dehydration could lead to serious consequences, such as impaired performance or potential medical issues.

While stretching exercises, changing into wrestling gear, and consulting with a coach are typically permissible activities that prepare wrestlers for competition, they do not pose the same level of risk as activities that purposely affect hydration. Thus, prohibiting activities that promote dehydration aligns with the overall emphasis on athlete welfare during the weigh-in process.
