الأسئلة الشائعة
What is a safe weight cut percentage in MMA?
Most sports medicine experts consider cuts up to 5% safe. Cuts of 5–8% carry moderate risk. Anything above 8% significantly increases risk of heat illness, kidney stress, and impaired performance.
How do fighters cut weight?
Common methods include water restriction, sauna use, and sweat suits in the days before weigh-in. These methods are risky and should only be done under medical supervision.
How quickly can fighters rehydrate after weigh-ins?
With 24 hours between weigh-ins and competition (as mandated by major promotions), fighters can typically recover 50–70% of their acute weight loss.
