这项研究为测量婴儿体力活动 (PA) 强度建立了新的加速度计值. 这些发现对于监测幼儿活动水平和促进健康发展至关重要.

科学领域:

  • 儿科 儿科 儿科
  • 生物医学工程 生物医学工程
  • 运动学 运动学

背景情况:

  • 早期儿童缺乏体育活动 (PA) 与严重的健康问题有关.
  • 监测PA对于促进幼儿健康发育至关重要.
  • 现有的加速度计值仅适用于走路儿童,而不是走路前的婴儿.

研究的目的:

  • 开发和验证加速仪值,用于分类PA强度水平 (静止,轻度,中度至强度) 在行前婴儿.
  • 建立可靠的方法,在生命的早期阶段客观地监测PA.

主要方法:

  • 十名婴儿参加了这项研究,他们在卧卧姿势下自由运动时,在每个脚上戴着加速度计.
  • 视频录制是黄金标准,活动强度标记为两秒的时代.
  • 用两种优化方法分析了加速度计数据 (加速和冲动),以推导值.

主要成果:

  • 开发了四组值,适用于单个和双个加速度计的使用.
  • 典型使用的推基于加速度的值: 1.00 m/s2 (静止与轻度) 和 2.60 m/s2 (轻度与中度至强度).
  • 加速和冲动测量都被证明适用于婴儿的PA评估.

结论:

关键词:
婴儿 婴儿 婴儿 婴儿身体活动强度 身体活动强度这是一个门值.验证验证的时间一个可穿戴的加速计.
