This study aimed to compare time-motion analysis between weight divi-sions in male fighters and rounds of Mixed Martial Arts (MMA). The sample consisted of 2097 bouts separated by weight divisions (Flyweight n=114, Bantamweight n=224, Featherweight n=286, Lightweight n=450, Welterweight n=390, Middleweight n=316, Light heavyweight n=167, Heavyweight n=150) of 2012-2014 UFC™ events. The time-motion varia-bles were categorized into low or high-intensity, stand-up or groundwork situations by round. Effects of weight divisions were observed and the main results showed that, in the 1st round, the heavyweights (212.4±101.5s) presented with a shorter effort time than all other weight divisions (257.6±79.9s); in the 2nd round, the bantamweight competitors (132.8±90.9s) presented with the shortest total effort time (171.7±81.5s); in the 3rd round, the shortest total effort time was in the heavyweight divi-sion (246.3±89.1s) again, with the other weight divisions showing variable effort times, including: welterweight (289.6±42.3s), lightweight (280.3±57.3s), featherweight (281.4±58s), bantamweight (285.6±47.2s), flyweight (287.7±43.8s) and middleweight (268.3±72.2s). The present data suggest a focus on the intermittent demands presented in the various com-bat phases in MMA. Additionally, strength and conditioning coaches should pay particular attention to the high and low effort ratios for both standing and ground combat to most effectively condition their athletes.
