概括
自由维生素D和铁的状态显著影响青少年男性运动员的骨健康,自由维生素D是一个比总维生素D更好的指标.这项研究强调了这些微量营养素对身体活跃的年轻人皮质骨发育的重要性.
科学领域:
- 骨代谢和内分泌学 骨代谢和内分泌学
- 运动医学和营养 运动医学和营养
- 青少年健康 青少年健康
背景情况:
- 维生素D,和铁等微量营养素对骨健康至关重要,尤其是皮层骨.
- 之前的研究经常使用总量为25...OH) D来评估维生素D状态,可能忽略了自由分量的重要性.
- 这些微量营养素对青少年,特别是运动员的皮层和椎骨的特定影响需要进一步阐明.
研究的目的:
- 调查维生素D (总和自由分数) 和铁状态对腰椎骨健康参数 (Z-score,BMAD,TBS) 的影响.
- 检查摄入量与青少年男性骨状况相关的作用.
- 为了区分这些微量营养素对皮层与椎骨在腰椎骨的影响.
主要方法:
- 研究了一组113名15-19岁的男性受试者 (76名运动员,37名非运动员).
- 用双能X射线吸收计 (DXA) 评估腰椎骨状况,测量Z-score,骨矿物质表面密度 (BMAD) 和椎骨得分 (TBS).
- 测量了维生素D状态 (总和自由25(OH) D) 和铁状态 (血清费里丁);通过ADOS-Ca问卷评估了摄入量.
主要成果:
- 微量营养素和骨健康参数之间的显著相关性仅在运动员中观察到.
- 自由的25(OH) D与Z分数和BMAD有很强的相关性,而总的25(OH) D和铁状况只与BMAD相关.
- 自由25 (((OH) D和费里是BMAD最强的决定因素,分别解释了其变异的25%和7%;没有发现与TBS的关联.
结论:
- 维生素D和铁对身体活跃的青少年男性皮层骨状况有积极的影响,但对状骨的影响不大.
- 自由25OH) D是运动员骨健康的更敏感指标,与总25OH) D相比.
- 这些发现强调了优化维生素D和铁水平对年轻运动员骨健康的重要性.

01:25Role of Vitamins in Maintaining Bone Health
3.3K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

4.0K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

01:29Bone Disorders
3.5K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

4.5K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

01:17Hormones and Bone Tissue
2.7K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:40Bone Remodeling
38.3K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
