The practice of sports along with the benefits for health, has a positive influence in well-being and body image. Despite the great number of women performing sports there are only few studies about anatomical, psychological and especially hormonal aspects that affect performance, focusing in the influence of hormonal changes in the women body. A great part of these studies mention the relation between menstrual cycle and performance, but they don´t consider perimenstrual alterations. The prevalence of perimenstrual syndromes (PMS) in Brazil varies between 8 to 86%. These percentages enhance the importance of perimenstrual syndromes in the performance for competitive and non-competitive athletes. We studied thirtyone handball athletes, with normal menstrual cycles and non users of hormones. A questionnaire of pre-menstrual symptoms has been applied for three consecutive months and the diagnosis was made based upon the total score of six days preceeding menstruation, compared to the score of 5 to 10 days after menstruation. The diagnosis of perimenstrual syndrome was established when the athlete presented four or more symptoms, including one having to do with an altered mood. For the evaluation of strength we compared the capacity to perform resistance exercises of the abdominal wall muscles and leg muscles. The prevalence of perimenstrual syndromes in our study was 71%. We analyzed our data in a cross-sectional and longitudinal study, finding that athletes with PMS were less capable to do the resistance exercises during the pre-menstrual period compared to the post menstrual period, suggesting a decrease in performance. We were able to demonstrate that athletes evaluated in two different times showed a decrease in resistance of abdominal muscles ( p< 0,01 e p< 0,01), leg muscles ( p <0,01 e p < 0,07) and arm muscles ( p< 0,01 e p< 0,01) differences statistically significant. Asides the high prevalence of perimenstrual syndrome in the group of athletes we studied, we were able to demonstrate in this group a decrease in performance in athletes performing resistance exercises during pre-menstrual period.
