The Changes Of Weight Loss In UFC Female Fighters

Share Article

It is common practice for fight sport athletes to use a variety of weight manipulation strategies to compete in desired weight classes. Although numerous studies have highlighted rapid weight loss (RWL) strategies and the magnitude of weight loss, few have focused specifically on weight loss in female fighters. 

A collaboration between the UFC Performance Institute and Nova Southeastern University Fight Science Lab published in JISSN. Special thanks to Cassandra Evans lead on this project. A first effort in establishing norms in the worlds elite UFC Female Fighters.

This is the first study to provide descriptive statistics on weight cutting in female athletes competing in the UFC. The purpose of this study was to provide descriptive information on professional UFC female fighters engaging in RWL in all women’s UFC weight divisions. Females engaged in RWL practices lose weight in a similar fashion irrespective of weight class. Based on the available literature, the body mass loss(4.3-6.6%) and regained (8.9-9.8%) during this processare comparable to other fight sport athletes.

The following is an abstract of this study.

Background

It is common practice for fight sport athletes to use a variety of weight manipulation strategies to compete in desired weight classes. Although numerous studies have highlighted rapid weight loss (RWL) strategies and the magnitude of weight loss, few have focused specifically on weight loss in female fighters. The purpose of this study was to provide descriptive information on professional UFC female fighters engaging in RWL in all women’s UFC weight divisions: strawweight (52.2 kg): flyweight (56.7 kg); bantamweight (61.2 kg); featherweight (65.8 kg).

Methods

All fighter’s weights were obtained at five separate time points: 72 hrs. pre-weigh-in, 48 hrs. pre-weigh-in, 24hrs. pre-weigh-in, official weigh-in, and 24 hrs. post-weigh-in (competition weight). Mixed effects models and random effects analysis were used to assess changes in weight and differences between weight divisions. All statistics were analyzed, and significance was set at p ≤0.05. Significant changes in weight between all time points were reported.

Results

No statistical differences between weight divisions were observed. Female fighters lost 4.5–6.6% of their weight prior to the official weigh-in.

Conclusion

Females engaged in RWL practices lose weight in a similar fashion irrespective of weight class.
