概括
几种室内活动有效地促进学龄前儿童的中度至强度体力活动 (MVPA). 与直接观察相比,腰部和脚加速度计准确地测量了MVPA,支持它们在研究中的使用.
科学领域:
- 儿科运动科学 儿科运动科学
- 测量身体活动的测量方法
- 幼儿教育 儿童早期教育
背景情况:
- 在学龄前儿童中促进体育活动对于健康的发育至关重要.
- 确定适度至强度体力活动 (MVPA) 的可行和有效的室内活动是必不可少的.
- 在幼儿中精确测量MVPA存在挑战.
研究的目的:
- 评估室内活动的可行性和可接受性,以在学龄前儿童中实现MVPA.
- 为了比较从直接观测 (DO) 获得的MVPA估计,在各种位置 (脚,腰部,手腕) 用加速度计.
主要方法:
- 35名学龄前儿童 (3-4岁) 参加了6次6分钟的室内活动.
- 使用三轴加速度计 (Actigraph Gt3×BT) 在脚,腰部和手腕测量中度至强度的体力活动 (MVPA).
- MVPA还通过视频录像的直接观察 (DO) 来量化;父母和孩子的报告评估了可行性和可接受性.
主要成果:
- 幼儿园儿童在气球/气泡,骑自行车和电路比赛中至少50%的时间实现了MVPA.
- 腰部和脚的加速度计显示出与DO的强烈一致 (ICCs 0.70-0.84),而手腕的位置显示出相当低的一致 (ICCs 0.22-0.58).
- 家长和学龄前儿童 (≥4.0/5.0) 报告说,大多数活动都是可行的.
结论:
- 室内活动,如气球/气泡,骑自行车和电路,有望增加学龄前儿童的MVPA.
- 建议在学龄前儿童的基于加速度计的MVPA测量中使用腰部和脚的位置,因为它们与直接观察一致.
- 进一步的研究可以利用这些经过验证的方法,在幼儿环境中促进体育活动.

Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

Assessment of Ventilation
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
