概括
2型糖尿病 (T2D) 增加了客观的运动力度,通过更高的心率和乳酸水平来表明,即使考虑到健身. 然而,在患有T2D的个体中,感知劳动力 (RPE) 保持不变.
科学领域:
- 运动生理学 运动生理学
- 代谢障碍 代谢障碍 代谢障碍
- 心血管健康的心血管健康
背景情况:
- 2型糖尿病 (T2D) 与较低的体力活动 (PA) 率和心血管风险增加有关.
- 以前的研究表明,T2D的女性感知到的运动力度更高.
- 关于T2D对性别和劳动率的运动努力的影响,存在一个知识差距.
研究的目的:
- 调查T2D对运动力度的客观和主观指标的影响.
- 为了确定T2D是否在各种工作速度之间赋予了更大的运动力.
- 为了测试T2D状态增加在有氧值以下的运动力度的假设.
主要方法:
- 对50至75岁的男性和绝经后女性进行横截面研究.
- 在1.5英里,2.0英里和2.5英里/小时的跑步机上练习,测量心率,乳糖和感知劳动力 (RPE) 的评分.
- 线性混合效应模型分析了T2D的影响,控制了%VO2峰值,年龄,性别,PA和血糖.
主要成果:
- 二型糖尿病状态与心率 (p=0.02) 和乳酸 (p=0.01) 的升高显著相关.
- 在T2D状态和RPE之间没有发现显著的关联 (p=0.58).
- 在调整为%VO2峰值后,这些关联仍然存在.
结论:
- 在低至中等强度的运动中,T2D增加了运动力度的客观生理标志物,独立于心肺呼吸能力.
- 感知到的劳动力并不反映T2D患者增加的客观劳动力.
- 进一步研究T2D影响运动力和替代运动处方的生理机制是有必要的.

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...

Carbohydrate Metabolism
11.0K
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...

Pathophysiology of Diabetes
921
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,...

Diabetes: Symptoms, Diagnosis, and Complications
526
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...

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...

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...
