To investigate the level of anxiety and its relationship with interleukin (IL)- 10 (anti inflammatory cytokine that modulates mood swings) in a group of female soccer players.
Fifty-two eumenorrheic soccer players were evaluated (age 19.8 ± 4.7 years). The presence of premenstrual syndrome (PMS) and phases of the menstrual cycle were determined by a daily symptomreport (DSR) kept for 3 consecutivemonths. The concentration of cytokine IL-10 was determined from urine samples collected at four moments: at the follicular and luteal phases of the menstrual cycle, and before (pre) and after (post) the simulated game, and it was quantified by flow cytometry (Luminex xMAP - EMDMillipore, Billerica, MA, USA). The level of anxietywas determined through the BAI anxiety questionnaire answered by all athletes at the same time of the urine collection. The Student t-test, analysis of variance (ANOVA) and Pearson correlation with significance level at 5% were used for data analysis.
We showed that the prevalence of PMS among female soccer players is similar to that reported in the literature. In addition,we showed that the group withPMS has a higher level of anxiety compared with group without PMS (p = 0.002). Interleukin-10 analysis in players without PMS revealed that there was a significant decrease in the level of this cytokine before the game during the luteal phase when compared with the follicular phase (p < 0.05). The correlation analysis between IL-10 and anxiety showed a negative correlation post-game in the luteal phase in the group without PMS (p = 0.02; r = -0.50) and a positive correlation post-game in the luteal phase in PMS group (p = 0.04; r = 0.36).
Our results suggest that IL-10 may contribute to reduce anxiety in the group without PMS. This could be attributed to the fact that no IL-10 variation was observed in the group with PMS, which presented higher anxiety symptoms when compared with the group without PMS.

To identify and relate body fat percentage (skin fold measures), body mass index
(BMI) and age at menarcheto aerobic capacity using the indirect VO2
maximum value (VO2 max) of girls in the second cycle of primary school.
A total of 197 girls aged 13.0±1.2 years on average, students from two public
schools in the city of Atibaia in São Paulo, were evaluated. Anthropometric
evaluation of skin folds was performed using the Slaughter protocol for teenage
girls, and BMI (kg/m2) was based on "Z score" (graphic of percentile)
according to WHO recommendations. The Léger protocol was used to determine
VO2 max. Pearson linear regression and the Student t-test were used
for statistical analysis.
22.3% of the girls were overweight and 3.5% were obese according to the
classification proposed by the WHO; 140 (71.1%) girls reported menarche. The
average age at menarche was 12.0±1.0 years and was significantly higher in the
group with normal BMI (12.2±0.9 years) than in the overweight or obese groups
(11.6±1.0 years). The average indirect VO2 max value was 39.6±3.7
mL/kg/min, ranging from 30.3 to 50.5 mL/kg/min. The advance of chronological age
and early age at menarche were positively correlated with lower VO2 max
values.
This study showed that 25.8% of the girls had aBMI value above WHO
recommendations. Girls with higher BMI and higher body fat percentage had lower
VO2 max. The earlier age at menarche and the advance of
chronological age were the most important factors for the reduction of aerobic
capacity. The ageat menarche was higher in girls with adequate BMI compared
tooverweight or obese girls.
