高蛋白饮食与抵抗力和并发训练相结合,在16周内对男性的骨健康没有产生负面影响. 蛋白质摄入量高达3.2gkg-1 d-1没有导致运动导致骨去矿化.
科学领域:
- 运动生理学 运动生理学
- 营养科学 营养科学
- 骨的新陈代谢 骨的新陈代谢
背景情况:
- 抵抗训练 (RT) 和并发训练 (CT) 与不同蛋白质摄入量的联合训练对骨健康的影响尚不清楚.
- 之前的研究还没有广泛探索高蛋白饮食与不同的训练模式相结合.
研究的目的:
- 为了比较两个高蛋白饮食 (1.6或3.2克/公斤-1 d-1) 对抵抗训练的男性骨参数的影响.
- 为了研究RT单独对CT的影响,当与16周的高蛋白摄入量相结合时.
主要方法:
- 48名经过抵抗训练的雄性被分为四组 (每组n=12个),接受1.6或3.2gkg-1d-1蛋白质.
- 干预包括16周的单独RT或CT (RT + 耐力训练),每周四次.
- 干预前后测量骨矿物质含量 (BMC) 和骨矿物质密度 (BMD).
主要成果:
- 在腿,手臂,肋骨或骨盆的BMC或BMD上训练类型和时间之间没有显著的相互作用.
- 对于盆腔BMD和右肋骨BMC观察到显著的时间效应.
- 在腰椎和胸椎中发现了训练类型和时间之间的显著相互作用,在胸椎中发现了显著的时间效应.
结论:
- 高蛋白饮食 (1.6-3.2 g kg-1 d-1) 结合16周的RT或CT并没有对抵抗训练的男性的骨组织参数产生不利影响.
- 蛋白质摄入量为每日推摄入量的2-3倍,以及运动,似乎不会导致骨去矿化.
- 建议进行进一步的长期研究,以了解高蛋白摄入对骨健康的慢性影响.

Bone Disorders
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...

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...
Role of Vitamins in Maintaining Bone Health
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.
