概括
月经周期 (MC) 期间的荷尔蒙变化不会显著影响生物电阻分析 (BIA),空气位移囊造影 (ADP) 或皮肤折叠测量 (CAL) 的身体组成 (BC) 估计. 这些方法可靠地测量身体成分,无论MC阶段或使用荷尔蒙避孕药.
科学领域:
- 运动生理学 运动生理学
- 人类生物学 人类生物学
- 身体组成分析 身体成分分析
背景情况:
- 月经周期 (MC) 期间的荷尔蒙波动可以影响水分状态.
- 这种潜在的保留水分可能会影响身体成分 (BC) 测量,特别是那些对组织水分或体积敏感的测量.
- 像生物电阻分析 (BIA) 和空气位移透镜 (ADP) 等方法可能是敏感的,与皮肤折叠测量 (CAL) 不同.
研究的目的:
- 调查月经周期对身体组成测量的影响.
- 为了比较荷尔蒙避孕与没有荷尔蒙避孕对这些测量的影响.
- 评估BIA,ADP和CAL在MC的不同阶段的可靠性.
主要方法:
- 进行了一项重复测量的病例控制研究.
- 54名参与者 (19名荷尔蒙避孕药使用者,17名非使用者,18名男性) 进行了评估.
- 在四个不同的月经周期日使用BIA,ADP和CAL测量身体成分.
主要成果:
- 在MC中观察到身体组成的最小个体内变化 (CV% 0.5-5.2).
- 对于任何BC参数或测量装置,没有发现显著的时间效应或时间*组相互作用.
- 激素诱导的保留水分没有明显影响BIA,ADP或CAL的BC估计值.

Hormonal Regulation of the Menstrual Cycle
186
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...

Hormonal Control of the Ovarian Cycle
316
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

The Menstrual Cycle
474
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...

Oogenesis
63.1K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Ovarian Cycle
707
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...
