概括
较强的相对下半身和上半身力量与美国成年人较低的胰岛素高血压有关. 增加的强度,以相对下肢强度和相对握力来衡量,与改善的胰岛素平衡有关.
科学领域:
- 运动生理学 运动生理学
- 代谢健康 代谢健康
- 公共卫生 营养 公共卫生 营养
背景情况:
- 骨肌肉 (SM) 由于其对胰岛素敏感的性质,在葡萄糖平衡中起着至关重要的作用.
- 胰岛素抵抗,以慢性高血糖症为特征,是2型糖尿病的前体.
- 之前的研究表明,增强的SM强度和大小对胰岛素动态有积极的影响.
研究的目的:
- 为了研究相对下体强度和相对上体强度与美国成年人多样样样本中的高胰岛素血症之间的关联.
- 分析来自全国代表性调查的数据,以了解广泛人口中的这些关系.
- 为了确定更大的肌肉力量是否与改善的胰岛素调节相关.
主要方法:
- 利用了1999-2002年和2011-2014年国家健康和营养检查调查 (NHANES) 的数据.
- 包括50岁以上 (1999-2002) 和20岁以上 (2011-2014) 的成年参与者.
- 在非糖尿病成年人中使用日志禁食胰岛素的第75百分位数计算超胰岛素,并分析了相对下肢力量 (RLBS) 和相对握力 (RGS) 的四分位数.
主要成果:
- 在RLBS和RGS的四分位数增加和高胰岛素血症的发病率降低之间发现了反向的剂量反应关系.
- 观察到与平均胰岛素度相似的RLBS和RGS四分位数增加的类似剂量反应关联.
- 在对共变量进行调整后,较高的RLBS (Q2-Q4) 和RGS (Q2-Q4) 四分位数与较低的超胰岛素血的几率显著相关.
结论:
- 相对较低的身体强度和相对的握力强度表明与胰岛素平衡有良好的关联.
- 这些发现表明,肌肉力量的改善可能有助于改善代谢健康和胰岛素调节.
- 该研究强调了力量训练在管理或预防与胰岛素抵抗有关的疾病方面的潜在作用.

Obesity
383
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Insulin: Dosing Regimen and Adverse Effects
146
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Psychoneuroimmunology: Diabetes and Cancer
24
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...

Diabetes: Symptoms, Diagnosis, and Complications
508
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...
