How much weight can safely be cut for competition?

Sports medicine guidelines recommend cutting no more than 3–5% of body weight via acute dehydration. Cuts exceeding 8% significantly impair strength, reaction time, and cardiovascular output even after 24 hours of rehydration.

What is the optimal rehydration timeline after weigh-ins?

The most effective protocol rehydrates 150% of lost fluid mass within 4–6 hours using electrolyte solutions (sodium 60–80 mmol/L). Carbohydrate co-ingestion accelerates gastric emptying and muscle glycogen restoration.
