对参加中国乒乓球女二队冬训67名运动员的月经状况进行问卷调查。结果表明:早期、长期系统的乒乓球训练对女子运动员月经初潮无明显及不良影响,但是月经初潮年龄有变小的趋势;运动员月经周期异常、痛经和经前期症状发生率较高,但是就诊率较低,月经相关知识欠缺。建议:重视对女子后备力量实施青春生理卫生知识教育、鼓励运动员积极治疗、加强科学训练。 相似文献

女子举重在选材方面和技术规范方面基本与男子相同,但在心理、生理功能及运动素质上差别较大,突出的是女子青春期后的月经。因此在女子举重运动中,根据女子生理特点科学的安排训练,成绩才能很快得到提高。 以月经周期安排训练节奏 正常女子月经周期为28～30天,一般持续3～6天,这是个规律性的特点。女子举重训练应根据这个生理特点安排训练节奏。一名优秀的举重运动员,在训练中能够承受高强度的大运动量训练,并在比 相似文献

<正> 女子各器官、系统的机能几乎都有一定的特点,而生殖系统的特点是最突出的。由于生殖系统形态与机能的特点,形成女性所特有的月经周期。在安排体育活动和训练时,必须考虑和照顾这些特点。一、月经周期生育期的健康妇女,除妊娠和哺乳期外,生殖器官维持着周期性变化,其显著特点是周期性的阴道流血——月经。这种生殖周期称为月经周期。女孩第一次月经来潮称月经初潮。据我国最近的调查,城市女子月经的初潮为15岁,乡村为16岁。月经初潮的时间,受营养、健康状况、气候、地区、民族、遗传等因素的影响。有人认为运动员月经初潮年龄与普通人 相似文献

在举重运动训练中,如何合理地安排好女运动负荷是训练工作中一个极其重要的问题。女运动员在来月经时,激素分泌的周期变化会使机体其它器官系统的机能状况发生变化,进而影响运动能力。本文根据女子月经周期(28天为一月经周期)生理变化的特点对女运动员在周与周之间的运动负荷节奏进行如 相似文献

女运动员的月经 总被引：1，自引：0，他引：1
<正> 目前,我国各种年龄的妇女参加体育锻炼的人数迅速增加,加之现代很多运动项目的女运动员在青春前期和青春早期就已经开始从事系统训练,女子机体特殊的生物特点是月经。月经的出现是女子一生中很重要的生理和心理变化阶段。当前,一个迫切的任务是了解、研究和观察从事体育运动的女运动员进行运动训练对月经的影响和月经期进行体育锻炼,机体内发生的反应和运动能力的变化。研究对象及方法我们对西安体育学院4个年级186名女生,陕西省体校61名女运动员(月经已来潮者),陕西省运动技术学院(省女队)91名女运动女员共338名女运动员,并对西北大学文、理系二年级女生153人(非运动员)作为对照组,进行了年龄、运动年限,专项年限,月经初潮年龄,经期血量,经期血色,月经持续时间,经期参加运动训练和比赛的人数, 相似文献

以我国优秀举重运动员为研究对象，以年龄为依据，采用数理统计和文献资料法。界定我国优秀举重运动员各训练阶段。并对各训练阶段下的运动等级组成与竞技成绩进行相关分析研究，以验证训练阶段划分的科学性和有效性。结果表明：我国优秀男子举重运动员的专项提高阶段为16-18岁，最佳竞技阶段为19-24岁。竞技保持阶段为25-29岁；女子各阶段的来临较男子早1．2年；另外，无论从运动等级在各训练阶段上的人数分布，还是各训练阶段下运动成绩的变化轨迹，均能证明对我国优秀举重运动员训练阶段的划分是正确的、也是可行的。 相似文献

采用问卷调查了我国优秀女运动员76名,一般运动员83名,业体校学员136名和330名非运动员的初潮年龄和月经期主要特征。结果表明:同非运动员相比,优秀女运动员的初潮年龄有所推迟,而业体校学员初潮年龄则有所提前。月经不良反应,优秀运动员占51.32％,业体校学员占71.32％,非运动员占51.21％。月经期不良反应与初潮来临的季节有一定内在联系。提示:初潮年龄和月经期不良反应的症状和程度,可作为选材和医务监督的指标之一。 相似文献

Abstract Ages at menarche and selected menstrual characteristics in 204 nonathletes, 253 high school athletes, 386 college athletes, and 40 young top athletes of Japan were investigated by questionnaire. Data from the questionnaire have confirmed (a) the ascending trend of ages of menarche with advancement of training and competitive level, and (b) the diversity of mean age at menarche by sport in a given level. The menarcheal orders by sport in the literature have been found to be strikingly similar to those found in the present data. We offer the hypothesis that ages at menarche and selected menarcheal characteristics (a) are brought about by selection in the socialization process into sports participation, and (b) reflect the diversity of suitable physiques by sport. Also, the higher the training and competitive level, the more likely the occurrence of menstrual irregularity (cycle length and period duration) and/or dysmenorrhea (backache). 相似文献

Menstrual disorders are common among female athletes and ballet dancers. Endocrine changes, such as high testosterone (HT) levels and high luteinizing hormone (LH)/follicle-stimulating hormone (FSH) ratios, may suggest functional ovarian hyperandrogenism which may induce such dysfunction. The aim of this study was therefore to evaluate endocrine status in female athletes and ballet dancers with menstrual disorders. Their nutritional status and dietary habits were analysed in relation to the testosterone levels. In a cross-sectional approach, 31 female athletes (18.1 ± 2.6 years) and 21 ballerinas (17.1 ± 0.9) with menstrual disorders participated in the study. The levels of serum LH, FSH, progesterone (P), estradiol (E2), prolactin (PRL), thyroid-stimulating hormone, testosterone (T) and sex hormone-binding globulinwere measured to assess hormonal status. In addition, the free androgen index (FAI) was calculated. Nutritional status, total daily energy expenditure and nutritional habits were evaluated. Girls were assigned to one of the following groups: low testosterone (LT) level, normal testosterone level or HT level. There were significant differences between ballerinas and other female athletes in terms of testosterone levels, FAI, age at the beginning of training, length of training period and age at menarche. The PRL level was lowest in the LT group while the FAI index was highest in the HT group. Daily energy and carbohydrate intakes were significantly lower in the HT group. T levels in the study subjects were found to be associated with nutritional factors, energy availability, age at the beginning of training and frequency of training. This is the first report of HT levels being associated with the status of a female ballet dancer, the age of menarche and the length of the training history. Further research is necessary to confirm the results in a larger study group. 相似文献

Given the lack of relevant data, the aim of this study was to examine femur cortical and trabecular bone in female and male professional ballet dancers. 40 professional ballet dancers and 40 sex- and age-matched non-exercising controls volunteered. Femoral bone density was scanned by dual-energy X-ray absorptiometry (DXA) scan. A 3D-DXA software was used to analyse trabecular and cortical bone. Anthropometry, maturation (Tanner staging), menstrual parameters (age at menarche and primary amenorrhea), energy availability and nutritional analysis (3-day record) were also assessed.Compared to non-exercising participants, dancers exhibited significantly higher volumetric density for integral, cortical and trabecular bone, and thicker cortex at the femur. Ballet dancers demonstrated lower body weight compared to controls (p < 0.01). Female dancers had their menarche later than controls, and the prevalence of primary amenorrhea were significantly higher in dancers than controls (p < 0.01). Dancer’s energy availability was below the normal range (<30 kcal/kgFFM/day). Despite the presence of certain osteoporosis risk factors such as low energy availability, primary amenorrhoea and lower body weight, professional ballet dancers revealed higher bone density for both cortical and trabecular bone compartments compared to controls. 相似文献

利用问卷调查法、记录法和数理统计法,对重庆工程职业技术学院2010级55名女中学生进行的一学期调查,结果显示：职业学院女学生经期情况痛经自评情况较为严重,从女学生经期症状统计情况来看,女学生痛经情况不算严重,女学生经期情绪非常的低落;学生体育课经期女学生体育课程缺席率非常高,表示经期不喜欢上体育课的人数比例较大,严重的影响了体育课程的正常进行;女学生经期课外体育运动喜欢趣味性强、运动对抗性弱、运动量较小的项目,但是对经期参加课外体育运动持高度反对的态度。笔者根据上面调查情况,提出了提高生理认识、降低心理压力、加强经期健康锻炼的教育、适当安排运动量等建议。文章研究女学生经期参加体育运动情况,旨在为女学生经期锻炼提高依据,为培养职业学院女学生养成正确锻炼习惯,形成正确的锻炼认识提供理论参考。 相似文献
