概括
水解原蛋白 (HC) 补充剂与抵抗运动 (RE) 结合,显著增强了中年男性的肌 (PT) 截面 (CSA),硬度和模. 这表明HC可以改善这种人口中的肌适应性.
科学领域:
- 运动科学 运动科学 运动科学
- 运动生理学 运动生理学
- 营养生物化学 营养生物化学
背景情况:
- 众所周知,抵抗运动 (RE) 可以增强肌的特性,而水解原 (HC) 补充剂在年轻人群体中显示出好处.
- 补充HC与RE一起改善中年人肌适应的疗效仍未得到充分研究.
研究的目的:
- 为了研究12周的RE与HC补充剂相结合对中年男性骨 (PT) 特性的影响.
- 为了确定HC补充是否会增加PT横截面积 (CSA),度和Young模块的变化,这些变化是由该年龄组的慢性RE引起的.
主要方法:
- 一项为期12周的双盲研究,涉及20名娱乐活跃的中年男性 (47±5岁),随机分配到安慰剂 (PLA) 或原蛋白 (COL) 组.
- 两组每周两次接受渐进的下肢RE,在运动后接受30gHC的COL和接受马尔托德克斯林安慰剂的PLA.
- 评估包括10重复最大 (10-RM),肌肉厚度,PT CSA,最大自愿扭矩 (MVT),扭矩发展的峰值速度 (pRTD),PT刚度 (k) 和Young的模量 (E).
主要成果:
- 虽然RE单独改善了两组的MVT,pRTD,10-RM和巨大的侧面体厚度,但COL组在PT CSA (p=0.027) 中表现出显著更大的增加.
- 与PLA组相比,COL组在PT刚度 (k,p=0.009) 和Young模量 (E,p=0.018) 中也显示出明显的改善.
- 对于MVT,pRTD,10-RM或肌肉厚度,没有观察到显著的按时间分组相互作用.
结论:
- 在中年男性中,经过12周的耐力运动和30克水解原蛋白补充剂,状肌横截面积,度和Young的模量显著增加.
- 这表明,水解原蛋白补充剂可以增强中年人群中抗力训练的肌结构和机械适应性.

01:12Renewal of Skin Epidermal Stem Cells
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...
01:19The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
01:24Muscle Recovery and Fatigue
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective response...
01:27Exercise and Muscle Performance
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

01:22Development of Immunocompetence
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

01:26Cellular Adaptation II: Hypertrophy
Hypertrophy is the increase in the size of individual cells, resulting in the enlargement of a tissue or organ. Unlike hyperplasia, which involves an increase in cell number, hypertrophy is characterized by an increase in cell volume. This process often occurs in response to higher functional demand or hormonal stimulation, leading to the production of more structural proteins and organelles, thereby enhancing the cells' work capacity.There are two primary types of hypertrophy: physiological...
