概括
2型糖尿病 (T2D) 在高温运动期间损害了全身出汗,特别是在更高强度的运动中. 这些出汗缺陷在干上比在四肢上更明显.
科学领域:
- 运动生理学 运动生理学
- 热调节 热调节 热调节
- 糖尿病研究 糖尿病研究
背景情况:
- 2型糖尿病 (T2D) 与在热的运动中减少出汗有关.
- 目前尚不清楚这种出汗障碍是否依赖于强度或在身体各区域均.
研究的目的:
- 研究运动强度对全身和局部出汗率对T2D和没有T2D的男性的影响.
- 为了确定与T2D相关的出汗障碍是否在不同的身体区域 (干部与四肢) 均.
主要方法:
- 直接热量计和通风囊技术分别测量了全身和局部出汗率.
- 身体活跃的2型糖尿病患者和对照人群在炎热干燥的环境中 (40°C) 进行轻度,中度和强度强度的运动.
主要成果:
- 在T2D组中,在中度和剧烈运动期间,全身出汗显著降低,但不是轻度运动.
- 在T2D组中,在强度运动中,汗流率的减少是强度运动的2.3倍,而不是轻度运动的2.3倍.
- 在剧烈运动期间,局部出汗障碍是特定区域的,干部 (胸部,背部) 的减少比四肢 (大腿,手臂) 的减少更大.
结论:
- 与T2D相关的出汗障碍取决于运动强度.
- 与四肢相比,这些损伤在干部更大,表明分布异质.

Carbohydrate Metabolism

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Diabetes Mellitus: Overview and Type I Subtype
2.6K
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Diabetes Mellitus: Type 2 and Gestational
2.3K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Psychoneuroimmunology: Diabetes and Cancer

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
