Aim: To characterize the changes in body composition, mood state and cardiac autonomic modulation in Brazilian Jiu-Jitsu (BJJ) of athletes in the pre- and post-competitive periods. Methods: Eight male athletes were evaluated in 3 moments: 14 days and 1 day before the fight, and 2 days after the competition. Evaluations of body composition, mood state, and cardiac autonomic modulation were performed. The repeated measures Anova test, Pearson and Spearman correlation were used for data analysis (p < 0.05). Results: We observed reductions in anger (6.80 ± 1.69 vs. 4.20 ± 1.67 vs. 3.40 ± 1.07) and tension (6.60 ± 0.81 vs. 5.40 ± 0.75 vs. 2.60 ± 0.88) after competition. Vigor was reduced one day before the competition and remained the same two days after the competition (12.80 ± 1.60 vs. 10.00 ± 1.95 vs. 10.40 ± 1.03). In addition, there was an increase in sympathetic modulation (LF-PI: 2942 ± 655.3 vs. 5479 ± 2035 vs. 5334 ± 2418 abs). There was a positive correlation between the state of vigor and sympathetic modulation (r = 0.55), a negative correlation between the states of depression and sympathetic modulation (r = -0.68) and confusion and sympathetic modulation (r = -0.67). Conclusion: These findings raised concerns about the preparation of these athletes for competitions since changes in the state of vigor might reduce performance and increase cardiovascular risk.

Atherosclerosis is a chronic inflammatory disease characterized by the formation of atheroma plaque in the arterial wall, process that causes long-term obstruction of the arteries. Postmenopausal women tend to have greater body adiposity, factor that corroborate to increased risk of cardiovascular events and development of atherosclerosis. Therefore, the aim of this study was to evaluate the association of experimental model of atherosclerosis with ovarian deprivation and consumption of high-fat diet in metabolic, hemodynamic, and autonomic outcomes. 21 female ApoE-Ko were divided into 3 groups (n = 7 in each): control treated with normolipidic diet (C); ovariectomized treated with normolipidic diet (Ovx); ovariectomized treated with high-fat diet (OvxHF). Hemodynamic parameters, baroreflex sensitivity and cardiovascular autonomic modulation were evaluated. Values (mean ± standard error of mean) were analyzed by One-way ANOVA, followed by Tukey's post hoc (p
