女子篮球运动员月经周期中PWC＿（170）及Vo＿2max的变化规律初探 总被引：3，自引：0，他引：3
本研究的目的在于观察女子有氧工作能力在月经周期各时相中的变化规律及特征。经严格统一标准划分月经周期各时相，以卡尔普曼方法测定受试者各时相ＰＷＣ１７０值，并据Ａｓ－ｔｒａｎｄ公式推算出Ｖｏ２ｍａｘ。结果显示：ＰＷＣ１７０及Ｖｏ２ｍａｘ呈同步变化效应，两项指标测定值由低到高的顺序均为：经前期、经期＜卵泡期，排卵期＜黄体期。Ｐ＜０．０５～０．０１，而且ＰＷＣ１７０与Ｖｏ２ｍａｘ在各时相均呈现高反正相关。结果表明，受试者月经周期黄体期具有较强的有氧工作能力，机体承受负荷的能力亦强于其它时相，这也提示我们以Ｖｏｘｎａｘ、ＰＷＣ１７０两项指标来综合评价运动员有氧工作能力具有一定实际意义和应用价值。 相似文献

对少年女子游泳运动员血红蛋白、无氧阈、有氧能力随月经周期呈规律性变化的研究 总被引：7，自引：2，他引：5
为掌握女子运动员的月经周期对运动能力影响的规律 ,本文对 2 3名 12～ 15岁少年女子游泳运动员的血红蛋白、无氧阈、有氧能力随月经周期呈规律性变化进行了研究。研究结果表明 :运动员的血红蛋白值呈周期性波动 ,这种波动与月经周期有密切联系 ,波动的差值有显著性差异 ;血红蛋白高峰时 ,无氧阈曲线右移 ,有氧能力提高。据此 ,可以从调整月经周期入手 ,调整血红蛋白峰值出现的时间 ,从而控制有氧能力高水平出现的时机 ,使运动员最佳身体状况出现在竞赛时 ,对进一步科学安排运动训练和比赛提供了理论依据。 相似文献

体育院系女生与女大学生月经不同时相植物神经机能探析 总被引：2，自引：0，他引：2
对 51名体育院系女生 (实验组 )和 51名非运动员女大学生 (对照组 )在月经周期的行经时相、卵泡时相和黄体时相进行直立试验和卧倒试验 ,比较其植物神经机能的变化。实验结果表明 ,各组在月经周期不同时相的心率和植物神经指数的变化没有显著差异 (P >0 0 5) ;在月经周期的同一时相实验组的心率和植物神经指数的变化幅度比对照组小 ,具有显著性差异 (P <0 0 1) ,这可能是对运动应激适应的结果 ,它有助于植物神经对内脏机能的有效调控 ,满足肌肉活动和提高运动能力的需要。 相似文献

女子短跑运动员月经周期运动能力的初步研究 总被引：3，自引：0，他引：3
本文运用“双盲”实验的方法,对短跑运动员在月经周期中运动能力的变化情况进行了研究。发现运动员的运动能力与体内孕酮的浓度呈正相关;与雌二醇的浓度呈负相关。在月经周期三个阶段运动能力在排卵后期最强,其次是月经后期,而排卵期则较差。 相似文献

现在女子在从事身体训练时具青春期变化的特点已成了许多专家的研究课题、人们从过去研究中得出的一个主要结论,就是女子在月经周期不同阶段从事紧张的肌肉工作时,必须考虑到自己的机能状况。 相似文献

ABSTRACTPurpose: 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

Waiter’s serve (WS) is a specific tennis serve posture frequently observed in young players, and commonly considered as a technical error by tennis coaches. However, biomechanical impact of WS is unknown. The aims of this study were to identify the potential consequences of WS in young elite players relating to performance and injury risk, and to explain the kinematic causes of WS. Serve of 18 male junior elite players (Top 10 national French ranking, aged 12–15 years) was captured with a 20 camera, 200?Hz VICON MX motion analysis system. Depending on their serve technique, the players were divided into two groups (WS versus Normal Serve [NS]) by experienced coaches. Injury data were collected for each player during a 12-month-period following the motion capture. Normalized peak kinetic values of the dominant arm were calculated using inverse dynamics. In order to explain WS posture, upper limb kinematics were calculated during the cocking and the acceleration phases of the serve.

Twenty highly trained, eumenorrhoeic female endurance runners were studied over three consecutive menstrual cycles. Average training distance per week, total years training and mood states were recorded throughout the three cycles. Salivary progesterone and menstrual cycle diaries were recorded over the first two cycles to identify luteal phase onset and the presence of any menstrual irregularities. Saliva samples were collected daily over the third cycle for analysis of immunoglobulin A (IgA) concentration and secretion and saliva flow rate. Twoway analysis of variance (ANOVA) revealed no significant differences in mood states across the phases of the menstrual cycle ( P > 0.05). Training logs indicated that training did not alter throughout the 3 month study. One-way ANOVArevealed no significant differences in IgA concentration ( P = 0.92), secretion rate ( P = 0.84) or saliva flow rate ( P = 0.95) across the phases of the menstrual cycle. Pearson's product-moment correlation revealed no relationship between IgA concentration and progesterone between the phases of the cycle ( r = 0.39). We conclude that, in ovulatory female endurance runners whose physical and emotional stress are stable, IgA concentration is not significantly affected by fluctuations in progesterone during the menstrual cycle. 相似文献

The purpose of this study was to determine if a difference in interleukin-6 (IL-6) and delayed onset muscles soreness (DOMS) exists in two different phases of the menstrual cycle. Nine runners performed one 75-min high-intensity interval running session during the early follicular (EF) phase and once during the midluteal (ML) phase of the menstrual cycle. Estrogen and progesterone levels were significantly reduced in the EF phase when compared to the ML phase. IL-6 levels increased from pre- to postexercise in the EF and ML phases (p < .001). There was no relationship between the IL-6 level and DOMS. The results suggest that menstruating female runners need not vary training throughout the month to reduce DOMS. 相似文献

Abstract A random group of 24 college women was tested during four phases of the menstrual cycle to determine if the cycle had an effect on pulse rate and blood pressure before and after exercise. Analysis of variance data indicated that fluctuations in pulse rate and blood pressure before and after exercise could not be attributed to the menstrual cycle. 相似文献
