目的探讨不同人工调整月经周期方法(提前法和推迟法)对运动员机能及运动能力的影响,制订人工调整月经周期的最佳方案,为合理指导人工调整月经周期方法提供理论依据。方法将女运动员随机分为提前组和推迟组,每组7人。提前组在月经周期第5天开始服药(妈富隆),每天1片,服用14 d;推迟组在月经周期第24天开始服药,每天1片,服用10 d。分别于服药前一周期第(5±1)天、第(22±1)天,服药周期中的最后一天(提前组于服药第14天,推迟组于服药第10天)及服药后下一周期第5天进行血液指标和运动能力测试。结果服药期间血T、血C、T/C及服药后下一周存在时间主效应,血T、T/C降低有统计学差异,血C升高有统计学差异;平均握力、下肢爆发力前后比较无统计学差异;PWC170和V.O2max前后比较无统计学差异,反应时在服药后下一周期第5天与服药前周期同一时间相比有统计学差异。结论提前法和推迟法在调整月经周期中对运动员有氧能力、力量素质、反应时、血T和血C水平的影响无统计学差异,但是妈富隆能降低血T、T/C及升高血C水平,且对降低T/C的影响更加明显。建议运动员可以通过提前法调整月经周期,避开比赛期。  相似文献

对13名优秀中国式摔跤女子运动员的月经状况进行问卷调查,并与专家和教练进行座谈,了解受试者的月经情况。结果显示:1)月经周期规律者占38.5%,不规律者占61.5%;2)经期正常参加训练和比赛者分别为76.9%和84.6%,训练或比赛后身体有不适反应的分别达90%和90.9%,而比赛成绩正常的只有9.1%,且痛经发生率高达92.3%;3)经期训练和比赛、精神和情绪因素、膳食营养、体脂率低及经期卫生知识缺乏等是月经失调发生率较高的主要原因。  相似文献

ABSTRACT

Purpose: Heat intolerance (HI) is determined in the Israel Defense Force according to a heat tolerance test (HTT) before returning to duty after an exertional heat stroke (EHS) event. Recently, increased numbers of female combatants resulted in an increased number of EHS cases among women and a higher percentage of heat intolerance (HI) individuals. We aimed to evaluate the differences between tolerance to heat among women performing an HTT in relation to their menstrual cycle phase. Method: Thirty-three female participants were sorted into two groups: HI and heat tolerant (HT) according to two HTTs performed during both the luteal and follicular phases of the menstrual cycle or while consuming and during a break from consuming contraceptives. Results: HT women had an 18% higher maximal oxygen uptake (p < .005, 95% CI [2.6,9.8]) and 1.2% lower skin temperature in the HTT at the during and follicular phases (p < .01, 95% CI [0.12,0.77]) and 1.7% lower at the off and luteal phases (p < .001, 95% CI [0.34,0.92]). The mean sweat rate was 14% lower among the HI group only at the HTT at the during and follicular phases (p < .05, 95% CI (3,88)]). Conclusion: We found that HT can be predicted using aerobic capacity and core body temperature. Moreover, during the luteal phase, women presented altered thermoregulation that decreased the probability of being HT. This emphasizes the importance of considering the HT/HI criteria in the HTT for women, according to their aerobic ability and menstrual-cycle phase.  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

Abstract

Nine trained trackmen were divided into experimental (nonmilk) and control (milk) groups. Both groups participated in eight weeks of training. The experimental group was not permitted any milk, cheese, or ice cream except in those dishes in which milk was used in cooking. The controls consumed a minimum of three pints of milk daily and about two pints of ice cream each week. Steady state and all-out treadmill measures were obtained as well as diet recall records. During the period of this investigation no significant effects which might be attributed to milk were observed on performance. With exclusion of milk from the diet the intake of calcium, vitamin A, and riboflavin dropped significantly and below the recommended minimum allowances.  相似文献

在一个月经周期中,女性体内激素和对物质代谢调节的变化对于运动能力有一定影响。关于月经周期对葡萄糖代谢动力学的研究发现,黄体期葡萄糖Ra和Rd降低,而且女性在卵泡期要比在黄体期耐力性运动的运动能力更为强一些。通过补糖可以使这种差异减小,建议女运动员如果在黄体期参加运动,尤其是耐力性运动,要注意保证摄入充足的糖。  相似文献

Abstract

Response distortion is an acknowledged concomitant variable in psychometric research. Although the influence of response bias on the Estimation scale of the Physical Estimation and Attraction Scales (PEAS) has previously been considered for adolescent males, experimental evidence concerning the sensitivity of the adult versions of both the Attraction and Estimation scales to “faking” has not been provided. To determine this sensitivity, adult versions of the PEAS were administered to male and female undergraduates (N = 122). Subjects were randomly assigned to one of three groups and received either “fake bad,” “fake good,” or standard instructional sets. Results generally supported the view that the total score on each of the Attraction and Estimation scales is relatively insensitive to attempts to “fake good.” However, attempts to “fake bad” consistently resulted in a significant decrease (p < .01) in both Attraction and Estimation scores as compared to a standard control group. These findings suggest the need for a criterion to detect suspected “fake bad” Attraction and Estimation responses and possibly a “fake good” Attraction response. Statistical procedures for determining test bias indicated that specific PEAS items discriminated between the experimental and control groups, and these items were incorporated into embedded scales for the detection of a distorted PEAS response. Evidence for the predictive validity of these “fake bad” and “fake good” scales was provided.  相似文献
