MELEGARIO, Solange Mattos et al. The influence of the menstrual cycle on the flexibility in practitioners of gymnastics at fitness centers. Rev Bras Med Esporte [online]. 2006, vol.12, n.3, pp. 125-128. ISSN 1806-9940. http://dx.doi.org/10.1590/S1517-86922006000300003.
This study aims to verify if there are differences in the degree of flexibility in the phases of the menstrual cycle of adult young women who practice gymnastics at fitness centers. A sample of 20 adult women aged between 18 and 35 years (25.8 ± 6.06) was studied; they had regular menstrual cycle (28 up to 32 days) and were not taking oral contraceptives. Information concerning the menstrual cycle and routine physical activity was obtained through a questionnaire. The flexibility was evaluated through the goniometry, using eight movements, in three phases of the menstrual cycle. The subjects were submitted to a hormonal test, where the estrone, estradiol and progesterone levels were verified. The statistics treatment was conducted through descriptive and inferential analysis; Kolmogorov-Smirnov's test and ANOVA were used to verify hypothesis. The results demonstrated that no significant differences (p < 0.05) in the flexibility degree were observed during the follicular, ovulatory and luteal phases of the menstrual cycle.
