Regulation of Hormone Secretion01:19

Regulation of Hormone Secretion

3.4K
Regulation of hormone secretion is a finely tuned orchestration driven by various types of stimuli, encompassing neural, humoral, and hormonal signals. Environmental cues instigate neural stimuli, where action potentials traverse nerve fibers to reach their designated targets. An illustrative scenario is the body's response to stress, wherein the sympathetic nervous system releases epinephrine from the adrenal glands, inducing the well-known 'fight or flight' reaction.

Hypothalamic-Pituitary Axis01:37

Hypothalamic-Pituitary Axis

59.8K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

Hormonal Regulation of the Menstrual Cycle01:22

Hormonal Regulation of the Menstrual Cycle

338
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...

Target Cell Response to Hormones01:22

Target Cell Response to Hormones

3.0K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

Hormonal Control of the Ovarian Cycle01:30

Hormonal Control of the Ovarian Cycle

461
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...

Hormones of the Adrenal Glands01:31

Hormones of the Adrenal Glands

2.4K
Adrenal hormones play a pivotal role in maintaining the body's electrolyte balance and orchestrating responses to stress, showcasing the intricate functions of the adrenal cortex and medulla.
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...

Area of Science:

  • Sports Science
  • Exercise Physiology
  • Endocrinology

Background:

  • Sports competitions create a stressful environment for athletes.
  • Physiological and psychological demands can impact athletic performance.
  • Understanding stress biomarker dynamics is crucial for athlete well-being.

Purpose of the Study:

  • To investigate the changes in stress biomarkers during an official national bouldering competition.
  • To analyze the physiological stress response of elite climbers under competitive conditions.

Main Methods:

  • Saliva samples were collected from 12 elite sport climbers (6 female) during qualification and final rounds.
  • Cortisol (C) and alpha-amylase (AA) levels were measured as indicators of stress.
  • Participants' demographic and training data were recorded.

Main Results:

  • Cortisol and alpha-amylase levels were significantly higher post-competition than pre-competition.
  • Cortisol levels were higher before the qualification round compared to the pre-final round.
  • Biomarker responses indicated a substantial endocrine and nervous system activation.

Conclusions:

  • Bouldering climbing competitions impose significant physiological and psychological stress on athletes.
  • The study confirms the stressful nature of elite sports climbing environments.
  • Monitoring stress biomarkers can provide insights into athlete adaptation and performance.
