概括
精英运动员有时会滥用甲状腺激素 (TH) 来提高表现,但报告的使用量有所下降. 这项研究追踪了近期奥运会的TH使用情况,发现运动员报告的病例减少.
科学领域:
- 运动医学 运动医学
- 内分泌学 在内分泌学.
- 绩效提升 提高绩效的方法
背景情况:
- 甲状腺激素 (TH) 是用于治疗甲状腺疾病的药物,但一些没有确诊甲状腺疾病的运动员有争议地使用它.
- 运动员可能会滥用甲状腺素 (T4) 和/或三甲状腺素 (T3),相信它们提供人体效益或帮助体重控制,尽管证据有限.
研究的目的:
- 调查参与东京2020年,北京2022年和巴黎2024年奥运会的精英运动员中自我报告的甲状腺激素使用率和趋势.
- 根据运动员人口统计数据 (如性别,年龄,国家和运动) 分析甲状腺激素使用模式.
主要方法:
- 数据收集涉及自报的甲状腺激素 (TH) 使用在东京2020年,北京2022年和巴黎2024年奥运会测试的运动员.
- 分析的重点是总体患病率,随时间的推移趋势以及不同人口群体和体育运动的变化.
主要成果:
- 在三个研究的奥运会中,1.7%的测试运动员报告使用甲状腺激素.
- 报告的TH使用在女运动员和爆炸性力量运动中更高.
- 报告的TH使用的下降趋势被观察到,从2020年东京的1.8%降至2022年北京的2.7%,并在2024年巴黎进一步下降至1.3%.
结论:
- 虽然在没有甲状腺疾病的精英运动员中报告了甲状腺激素的使用,但在最近的奥运会上观察到使用量的显著下降.
- 该研究无法最终确定这种下降是由于对潜在危害的认识增加,还是由于承认缺乏绩效益.

01:18Functions of Thyroid Hormones
3.2K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

01:20Synthesis and Regulation of Thyroid Hormones
5.2K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

01:23The Thyroid Gland
4.4K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

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.

01:27Major Hormones and Their Functions
817
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

01:22Target Cell Response to Hormones
3.6K
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...
