背景情况:
- 乳酸值 (LT) 是有氧运动表现的关键决定因素,与最大氧气消耗 (VO2max) 一起.
- 了解影响LT的因素对于优化运动员和休运动员的训练和表现至关重要.
- 在未经训练的女性中,月经周期 (MC) 对像LT这样的生理标记的潜在影响需要研究.
研究的目的:
- 研究不同月经周期阶段对未经训练的女性乳酸值 (LT) 的影响.
- 为了比较在MC的早期卵泡,排卵和中期乳液阶段的LT性能.
- 确定MC期间的荷尔蒙波动是否会改变LT的运动能力.
主要方法:
- 八个未经训练的雌性和八个未经训练的雄性 (对照组) 在循环人体计上进行了乳酸值 (LT) 测试.
- 在女性的三个MC阶段进行了测试:早期的卵泡 (menses),排卵期和中期的卵泡.
- 每隔3分钟测量血液乳酸盐水平,通过视觉检查 (LTvis) 确定LT,并确定度 (LT2.0mmol,LT4.0mmol).
主要成果:
- 对于女性参与者来说,在MC阶段之间没有观察到在LT的功率上有统计学意义的差异,无论使用的确定方法如何 (p>0.05).
- 作为对照组的男性参与者也没有在等效时间间隔 (p>0.05) 中显示LT功率的显著差异.
- 一个趋势表明,在所有LT确定方法中,与女性相比,男性的LT功率更高.
结论:

Hormonal Regulation of the Menstrual Cycle
269
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

The Menstrual Cycle
664
The menstrual cycle is a recurrent sequence of changes in the uterine endometrium, specifically its functional layer, the stratum functionalis. This cycle prepares the uterus for potential pregnancy. This cycle typically spans 21–35 days, averaging 28 days, and aligns with the ovarian cycle, regulated by fluctuating levels of ovarian hormones, primarily estrogen and progesterone.
The menstrual phase occurs from days 1 to 5 and involves the shedding of the stratum functionalis, as a...

Muscle Recovery and Fatigue
1.9K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

Ovarian Cycle
940
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

Menses Phase
210
The uterine cycle begins with the menstrual phase, which is considered day one of the cycle and typically lasts about five days. This phase is characterized by the degeneration and shedding of the stratum functionalis, the functional layer of the endometrium.
When fertilization does not occur, the corpus luteum deteriorates, causing a significant drop in the levels of estrogen and progesterone in the body. This hormonal decrease triggers the release of prostaglandins, which cause the uterine...
