In recent years the popularity of MMA has exploded. Organizations such as the UFC and Bellator have become global brands generating billions of dollars of revenue every year and producing several international superstars.
The number of rounds in a MMA fight may vary depending on the promotion. However, most leading promotions such as the UFC and Bellator follow the Unified Rules of Mixed Martial Arts. These unified rules were established to protect the safety of fighters.
This article will discuss how many rounds are in a MMA fight and how long each round lasts. We will also look at how the number and duration of rounds can depend on the organization.
Let's dive in.
The majority of American MMA organisations follow the Unified Rules of MMA.
The Unified Rules of MMA state:
Each round shall consist of a five minute duration, with a one minute rest period between rounds.
a. No contests shall exceed five rounds or twenty-five minutes.
b. Bouts may consist of one, two, three, four, or five rounds, with a five minute duration.
c. No contestant shall compete for more than five rounds or twenty-five minutes of fighting in a twenty-four hour period.
