[Sports performance of women during the menstrual cycle].

Sports woman performance during menstrual cycle has been examined by many Authors, but the comparison of performance during all menstrual cycle has been less examined. The results of a research carried out on a group of 40 women attending the Parallel Courses' of Verona, of ISEF of Bologna, are illustrated. The conclusion of this research are: a less sporting efficiency in the premenstrual period, a normal or almost normal efficiency in the other period, including the menstrual one as well.
