INTRODUÇÃO: O bicicleta menstrual excluir o principal doar por alterar da fisiologia feminina, que pode amigáveis algumas respostas morfofuncionais. OBJETIVO: verificar a relevante das muitos fases do bicicleta menstrual na flexível de denominações jovens. MÉTODO: 44 voluntárias dividir em um agrupadas controle (n = 24), que fez uso regula de contraceptivos hormonais, e um agrupado experimental (n = 20), que não utilizava anticoncepcionais, foram submetidas naquela três dias de avaliações, ns em cada estágio do ciclo menstrual (folicular, ovulatória e lútea). Foram avaliados dados antropométricos (massa corporal, catalogar de volume corporal, circunferência de cintura e abdômen) e de composição alicerçada (percentual de gordura e volumes magra). Der flexibilidade adquirindo mensurada pela do exame de sentar e abranger no banco de Wells. Aplicou-se, então, o teste que paramétrico de Mann-Whitney ao as comparações intergrupos e ministérios teste de Friedman para der comparação adentraram as muitos fases menstruais. Resultados: que foram encontradas diferenças significativas intra e intergrupos entre as diferente fases do ciclo (p > 0,05). Aquisição observada maior variabilidade no agrupado controle em comparação aos experimental. CONCLUSÃO: As diferente fases do bicicleta menstrual que interferem na flexibilidade de mulheres jovens, independente dá uso de anticoncepcionais hormonais.

ABSTRACT

INTRODUCTION: The período cycle is the main responsible porque o changes in female physiology, which may influence some morphofunctional responses.

OBJECTIVE: come investigate the influence of the different phases the the fisiológico cycle on ns physical adaptability of young women.

METHODS: 44 volunteers were separated into a direção group (n = 24), i beg your pardon made regula use of hormonal contraceptives, e an experimental group (n = 20), which go not use contraceptives. Tudo de volunteers underwent three mim of evaluations, one porque o each step of menstrual cycle (follicular, ovulatory and luteal). Anthropometric encontro (body mass, body mass index, waist and abdomen circumferences), e body composition encontro (body fat percentage e lean mass) were assessed. Flexibility foi ~ then analyzed through the sit and reach test on Wells bench. Ns non-parametric Mann-Whitney test era then applied porque o intragroup comparisons, e the Friedman test for comparison between the different menstruação- phases.

RESULTS: no significant differences between groups within e between various phases of a cycle to be observed (p > 0.05). Higher variability within the direção group foi ~ observed when contrasted to the experimentalmente group.

CONCLUSION: regardless of the período cycle phase e of ns use of hormonal contraceptives, a physical adaptability is not transformed in young women.

Keywords: joint selection of motion, gonadal hormones, menstruation period.

INTRODUCTION

The menstruação- cycle is naquela biological phenomenon which occurs in healthy women which has actually as significant characteristic the vaginal blood flow. Together phenomenon has naquela cyclic characteristic which wake up as der direct an outcome of variations of ns hormone concentration secreted by ns hypothalamus-hypophysis-gonadal axis1,2. The fisiológico cycle big in typical 28 days, and can be divided in 3 phases: follicular, ovulatory e luteal. Ns follicular phase starts on the o primeiro dia day of menstruation e lasts until a ninth day; ns ovulatory phase occurs between dia 10 and 14; and the luteal phase starts in the fim of the ovulation and lasts until a beginning the the período flow3. The use of hormone contraceptives avoids ovulation; the is to say, ns release of eggs by a ovaries (ovulatory phase) early out to a suppression of the gonadotropins secretion.

Some studies have analyzed a influence that the período cycle on some morphofunctional parameters such as anaerobic power4, pulmonary function5, resting metabolic rate6, corpo humano composition7, muscle strength8 and flexibility9-11. Moreover, reveja articles have reported divergence about a influence that the menstrual cycle ~ above the esportes performance12-14.

Different physics capacities demonstrate contradictory responses worrying the período cycle. Some studies report that a different phases of a cycle são de not interfere in flexibility9,10. On a other hand, Bell et al.11 found more extensibility of a hamstring muscles during the ovulatory phase once compared com the período phase (follicular).

It is speculated that the menstrual cycle might affect ns level that articular variety of motion. Despite of that, ns literature does not have actually it clear about ns influence the this relation in between women quem make use or not of contraceptive methods. Thus, ns present pesquisar had ns aim come verify the influence of the different phases that the período cycle on flexibility of apparently healthy young women.

METHODS

Sample recruiting and selection

82 apparently healthy and balanced women aged in between 18 e 40 years were conveniently recruited. Consists criterion selected those women who had complete knowledge about their menstrual cycle, which could be regulatório between 25 e 40 days4. After a initial selection, those quem reported background of any type of disorder related to ns endocrine sistema and/or quem did not have actually regular menstruação- cycle were excluded. Therefore, at first anamnesis foi ~ applied ao the primeiro triage of ns volunteers in which personal dia including name, age, address, telephone number, as well as information about the menstrual cycle and habitual prática of physical task were recorded. Those quem reported systematized physical activity practice ao at the very least three continually months com minimum frequency of 3 weekly days e time same or much longer than 30 minutes per session were classified together physically active.

After the initial procedures and drop-outs by several reasons throughout the encontro collection period, the sample was composed that 44 women who signed a Free and Clarified Consent type which respects the resolution # 196/96 that the national Health Board. Ns present study was it is registered to and approved by ns Ethics in pesquisar with human beings Committee of a Holy home of Mercy of juiz de Fora, MG, under the resfriamento opinion number 011/10.

Experimental protocol

After the initial procedures a volunteers were familiarized with the environment in i m sorry the encontro collection occurred and the professional associated in the experiment. Therefore, the sample foi ~ divided in dois groups: one experimental group (EG), which era composed that women who did no make usar of hormone contraceptive (n = 20, o fim of i beg your pardon 13 were physically active); e a ao controle group (CG), which was composed that women quem made use of hormone contraceptives porque o at least two cycles (n = 24, fora of i beg your pardon 11 physical active). Tudo of castle randomly paid three visits to ns laboratory der (individual x phase of the cycle: follicular, ovulatory and luteal).

The phases were defined concerning ns day of the cycle e subsequent encontro analysis according to ns criterion propose by Wojtys et al.3 para eumenorrheic ladies in which the follicular phase begins on the o primeiro dia day of a cycle, the is, in a beginning of ns menstruation, e lasts until ns ninth day; ns ovulatory phase occurs between days 10 and 14 e the luteal step begins são de the 15th day and lasts till the fim of ns cycle.

During each phase, ns anthropometric measures were collected (body mass, stature e BMI) e of body composition (fat percentage and lean mass) to avoid any kind of influence the the período cycle in the sample characteristics. The fat percentage foi ~ calculated through the Siri formula15 a partir de the body density estimated by the jackson et al. Equation16.

The equipe of the evaluations foi ~ standardized ao each volunteer de acordo com to the first visit to ns laboratory, keeping a distance em ~ the first and the last hrs of the day10.

Statistical treatment

A Kolmogorov-Smirnov normality test foi ~ applied to verify ns distribution of ns sampling data. Due to the fact that the dia did not existing Gaussian distribution, the descriptive outcomes were stood for by mean and standard deviation and the graphic values by median and amplitude.
