The obesity rates in the world’s population have been increasing each year, becoming a health issue that concerns all the age groups. Researches show that the obesity is an aggravating factor for women, because it directly affects their reproductive function. Physical activities, proper nutrition and, in some cases, the use of food supplements are the main factors to fight obesity. The metabolic changes resulting from an adequate food intake provide adaptations to training, which will contribute to the reduction of obesity, and consequently to the wellness. Aim: to analyze if the acute ingestion of Multi- ingredient pre-workout supplements influences significantly, in an acute way, the physical performance of sedentary obese women. Methodology: the research approved by the ethics committee of Júlio Müller Hospital (CEP/HUJM),consisted in a double -blind study, randomized with 23 obese and sedentary women, that after signing an Informed Consent Form (ICF), received medical care, filled in a socio-demographic questionnaire and performed the anthropometric measurements ( height and weight) and bioimpedance. After being divided in two groups (G1 and G2), in the first moment (M1) the MIPS, or placebo, was consumed. Then, 30 minutes later, physical activities were performed in the following sequence: hand grip strength test, scapular muscle strength test, lower back muscle strength test and lower extremities, vertical jump test on the platform, abdominal muscle resistance and push-ups. After 72 hours (moment 2 - M2) the volunteers ingested the opposite substance and repeated the tests. The analyzes were performed using the software SPSS® version 22. To test the normal distribution or not of the data, the Kolmogorov-Smirnov test was used. Student’s t-test was used for independent or paired samples and the Wilcoxon-Mann-Whitney test was used for non-parametric data. The difference in performance was calculated by Delta (△). Results are expressed as mean ± SD and the significance level adopted was 5%. Results: The results indicate that in the intragroup analysis the push -ups test showed significant results for both placebo (G1; 0.0206) and MIPS (G2; 0.0028). Regardless of being MIPS or placebo, it is more significant to consume at the second moment, and the best results are based on time rather than if it is placebo or MIPS. There is no difference between MIPS and placebo when the timing of ingestion is not considered, neither there is a difference in performance between groups 1 and 2. Conclusion: Acute intake of Multi- Ingredient Pre-Workout Supplement did not increase the physical performance of sedentary obese women.
