Introduction. The aim of this study was to analyze the magnitude and methods of weight loss among MMA fighters and the influence of this practice in hydration and profile of mood state. Material and methods. The sample was composed by eight MMA fighters during a professional MMA competition, but only five athletes finished all procedures. To evaluate the weight loss prevalence, magnitude and methods it was applied the Rapid Weight Loss Questionnaire adapted to MMA. Saliva samples were taken in the official weigh-in and one hour before of the combats to estimate the salivary osmolality. To evaluate the profile of mood states the Brunel Mood Scale (BRUMS) was applied. Results. The results showed that all participants already had lost weight to take part in another event. The athletes reported that they always adopted as method to lose weight: to make more exercise (50 %) and reduce food intake of liquids (37.5 %). The dangers methods to health were cited by athletes in the following sequence: use of diuretics (37.5%), sauna (37.5%), training intentionally in heated training rooms (50 %) and use of diet pills (12.5%). In the competition analyzed 88% of athletes reduced their body mass (4.5 ± 4.2 kg, 5.4 ± 4.3 %) to compete. The salivary osmolality did not show significant difference between weigh in (55.6 ± 30.7 mOsmol/kg H 2 O) and pre-match moment (40.2 ± 27.9 mOsmol/kg H 2 O). The profile of mood states did not change between the weigh-in (tension: 1.2 ± 1.8, depression: 0 ± 0, anger: 1.2 ± 1.6, vigour: 14.0 ± 0.7, fatigue: 2.6 ± 5.3, confusion: 0.2 ± 0.4) and the pre-match moment (tension: 2.6 ± 2.2, depression: 0 ± 0, anger: 1.4 ± 1.9, vigour: 15.6 ± 0.5, fatigue: 0.0, confusion: 2.8 ± 3.9). Conclusions. The conclusion is that there is a great prevalence of weight loss in MMA athletes in this sample. Furthermore, dangers methods to health are or were practiced to reduce the body mass to compete.
