如 表1所示，与对照组相比，运动组儿童的VPA和MVPA（64.20±2.33 vs 57.85±3.36，P<0.001）显着更高。根据以前在青少年25 和年轻人26中报告的结果，相对于主观调查，加速度计设备代表了一种准确的PA估计方法。
Bland-Altman 图表明，髋关节佩戴和腕戴式加速度计数据之间 MPA、VPA 和 MVPA 的一致性很高（ 如图 3</strong...

身体活动（PA）在儿童时期非常重要，与身心健康呈正相关。有充分的证据表明，PA在肥胖，骨骼健康，心理健康，认知功能和学业成就方面与学龄儿童的有益影响有关1，2，3。然而，中国大多数儿童的PA水平仍然低于4岁推荐的水平;此外，久坐时间会随着年龄的增长而增加。根据中国学生的全国体质与健康监测研究，在21世纪的前二十年中，肥胖学生的数量仍然很高5。
国际儿童和青少年 PA 指南建议每天至少进行 60 分钟的中度至剧烈体育活动 （MVPA），每周 3 天进行剧烈体育活动 （VPA）6，以获得健康益处。同样，根据国际PA指南，最新版本的《中国人体育活动指南》（2021）7强调，累积久坐行为时间不应超过60分钟。参加体育俱乐部或学校活动是儿童满足 PA 准则8 的一种非常有益的方式。乒乓球是一项在中国流行的复合且技术难度高的运动。最近的研究证实，定期的乒乓球训练对儿童和青少年的健康相关身体健康有积极影响9，10。因此，乒乓球俱乐部/学校培训是儿童提高PA11水平的非常合适的方法。
重要的是要考虑可能妨碍执行国际保护区准则所提建议的几个问题。例如，大多数儿童PA调查基于父母报告的问卷12;中国严重缺乏通过客观方法获得的数据。此外，儿童的活动模式的特征是相对较短的自发但强烈的PA13，14。这种模式很难仅通过观察来总结和报告;此外，问卷或家长报告容易出现错误15。其次，儿童在家中度过大量的闲暇时间，例如，在晚上和周末，并且倾向于在家庭环境中积累大部分日常PA。很难收集或估计儿童在课余时间的闲暇时间体育活动（LTPA）。LTPA对健康至关重要，是总PA16中最重要的组成部分之一。第三，儿童的PA可能受到性别差异和父母生活方式的影响8.总的来说，这些信息强调了获得PA的准确测量值的必要性，以评估整体健康状况，其社会影响及其在政策制定中的使用。如果特定亚人群（例如，接受乒乓球训练的儿童）的活动水平没有得到正确估计，数据甚至可能误导政策和公共卫生优先事项12。
作为青少年PA模式最广泛使用的客观测量方法，加速度计已被公认为测量17，18，19，20儿童PA的黄金标准。随着技术的进步，活动记录仪已经发展成为具有成本效益的电容式传感器。在大多数情况下，这些装置需要连接到右髋关节21，这可能是一个潜在的风险因素，并降低了顺应性22。近年来，一些研究表明，当设置适当时，从其他解剖位置佩戴的设备中获得的PA数据可以进行比较23，24。
在本研究中，我们旨在开发一种基于腕戴式活动记录仪加速度计的方法来评估接受乒乓球训练的儿童的PA。

physical activity measurement in children accepting table tennis training

越来越多的证据表明，中国大多数儿童的身体活动（PA）水平低于推荐指南。乒乓球是在中国流行的复合且技术难度较高的运动;在俱乐部进行乒乓球训练可以帮助孩子提高他们的PA水平。鉴于儿童无法自己完成自我评估问卷，并且基于照顾者的观察不适合儿童，我们假设基于活动记录仪的方法可以成为测量PA的客观方法。在本研究中，我们描述了一种可用于使用活动记录仪设备和软件评估PA水平的程序。此外，由于已知髋关节佩戴设备会降低依从性，我们试图评估髋关节佩戴和腕戴设备数据之间的一致性。总的来说，我们的结果表明，这些设备适用于测量PA和休闲时间身体活动（LTPA）水平。结合主观问卷调查，髋关节和腕戴式设备都非常适合评估在俱乐部接受乒乓球训练的中国儿童的PA。

人口统计数据如表1所示，包括性别、年龄、身高、体重、种族和惯用手。如表1所示，两组之间在性别、年龄、身高、体重和惯用手方面没有显著差异。此外，来自体育组的参与者在久坐行为（SB; 441.05 ± 31.80 vs 442.25 ± 30.74， P = 0.904）、LPA （213.10 ± 15.00 vs 215.65 ± 17.41， P = 0.623）、MPA（42.55 ± 3.80 vs 40.70 ± 2.85， P = 0.090）以及LTPA（1514.20 ± 146.10 vs 1587.70 ± </...

接受乒乓球训练的儿童的身体活动测量

An increasing body of evidence now shows that the majority of children in China experience lower levels of physical activity (PA) than the recommended ...

身体活动，PA，在童年时期非常重要。加速度计已被公认为测量儿童PA的黄金标准。基于腕戴式和髋部佩戴式活动记录加速度计的措施，用于在接受乒乓球训练的儿童中获取 PA。具有成本效益和准确性，具有高合规性。首先，参与者需要整天佩戴活动记录仪。其次，父母或看护人必须承认孩子的日程安排信息。排除被诊断患有任何神经发育障碍的参与者后，下载并运行该设备的软件。通过单击选择开始时间并输入日期和时间来输入收集数据的持续时间。单击“输入主题信息”按钮以输入人口统计信息，包括姓名、性别、身高、体重、出生日期和种族。单击侧面并选择右侧。如果参与者是左撇子，请选择另一侧。单击肢体，然后选择腰部。单击“支配”，然后选择“支配”。通过单击初始化 1 个设备来初始化数据收集。确保电池电量超过80%，否则初始化将失败。然后初始化以记录频率为 30 赫兹的原始加速度。指导参与者将加速度计戴在右臀部，并带有弹性腰带。确保加速度计位于髂嵴水平的右中腋线。设置相同的开始、日期和时间，以确保同时收集来自两个设备的数据。输入人口统计信息，并在参数中进行修改，例如：肢体，侧面和优势。对于左撇子参与者，请选择对面。指导参与者将加速度计戴在表带上非惯用手的手腕上，并提醒参与者整天佩戴设备，除了洗澡、游泳和淋浴时。对于收集的原始数据，根据 VM 图表获取由医生、机构研究人员或专业教练确认的数据。并计算并删除任何无法解释的极端数据。要求参与者整天佩戴该设备，并要求教练保持乒乓球训练计划的日记。要求父母在家记一本闲暇时间日记，指导父母收集日记中的睡眠数据、睡觉时间和醒来时间。从右臀部取下设备，然后使用 USB 电缆将其连接到笔记本电脑或个人计算机。运行设备的软件。通过单击下载下载参与者的加速度计数据，并在 60 秒内分析原始加速度计数据。从使用 USB 电缆连接到笔记本电脑的非惯用手上取下设备，然后按照前面所述下载数据。加速度计的原始加速度结果变量基于矢量幅度计数。根据训练、闲暇时间和睡眠日记，确认家中闲暇时间的加速度计数据。打开软件的评分页面，在页面左侧，选择算法，然后选择切割点和 MVPA。最后，点击普耀儿童2002。然后单击“计算”。其次是出口。评分输出将自动显示，包括SB，LPAS，MPA和MVPA。通过添加日记时间和定义闲暇时间和平均矢量幅度计数来获得日常休闲时间和身体活动。使用学生T检验测量P值小于0.05的组差异，并使用市售的统计软件包进行所有统计。人口统计数据显示，来自体育组的参与者在久坐行为方面没有表现出任何显着不同的参数。相比之下，运动组的儿童表现出明显高于对照组的VPA和MVPA。Bland-Altman图表明，髋关节佩戴和腕戴加速度计数据之间的一致性对于MPA，VPA和MVPA是可以接受的。对于收集的原始数据，需要医生或专业教练的确认;根据矢量幅度图，计数并删除任何无法解释和奇怪的数据。与主观问卷一起，如学龄儿童问卷中的班级行为问卷。该方法可以以非常有效的方式证明为儿童的PA。初步报告表明，活动记录仪还可以在临床实践中测量睡眠质量、昼夜节律和休息活动节律，这是对患有身体和精神障碍的儿童的一种反映。
