Children's lifestyles, behaviors, and educational activities were affected by COVID-19. The preschool children struggled with the challenge of learning at home and avoiding a rapid decrease in physical activity (PA). This study tested the effectiveness of a family-based intervention that integrated the family and preschool based on a smartphone app to improve the moderate-to-vigorous PA (MVPA) and physical fitness of preschool children during COVID-19.
This 8-week study was conducted using a quasiexperimental pre- and posttest design with a comparison group. A total of 66 pairs of preschool children (30 boys) and their parents and 44 preschool children (24 boys) and their parents composed the experimental group (EG) and the control group (CG), respectively. PA was measured using a GENEActiv waveform triaxial accelerometer. Children's physical fitness was assessed using a battery test from the Chinese National Measurement Standards on People's Physical Fitness for preschool children.
Preschool children and their parents in the EG participated in less sedentary ( < 0.01) and more light PA ( < 0.01) and MVPA ( < 0.01) compared with those in the CG at the late PA assessment. The EG significantly improved the mean performance of tennis ball throw ( < 0.05), balance beam walk ( < 0.01), and continuous jumping on both feet ( < 0.01) compared to the CG.
The family parent-child PA intervention based on a smartphone app can effectively increase the MVPA of preschool children and their parents, reduce sedentary time, and improve preschool children's physical fitness. Overall, the family parent-child PA intervention model based on a smartphone app for preschool children designed in this study is feasible and effective.
儿童的生活方式、行为和教育活动受到了 COVID-19 的影响。学龄前儿童在家学习时遇到了挑战，身体活动（PA）量迅速减少。本研究测试了一种基于智能手机应用程序的家庭为基础的干预措施的有效性，该措施整合了家庭和学龄前儿童，以提高 COVID-19 期间学龄前儿童的中等到剧烈体力活动（MVPA）和身体素质。
本研究采用准实验前后测设计，采用对照组进行了 8 周的研究。共有 66 对学龄前儿童（30 名男孩）及其父母和 44 名学龄前儿童（24 名男孩）及其父母分别组成实验组（EG）和对照组（CG）。使用 GENEActiv 波形三轴加速度计测量 PA。使用中国国民体质监测标准对儿童身体素质进行测试。
与 CG 相比，EG 中的学龄前儿童及其父母在晚期 PA 评估中，久坐时间（<0.01）和轻体力活动（<0.01）和中高强度体力活动（<0.01）减少。与 CG 相比，EG 组在网球投掷（<0.05）、平衡木行走（<0.01）和双脚连续跳跃（<0.01）方面的平均表现显著提高。
基于智能手机应用程序的家庭亲子 PA 干预可以有效增加学龄前儿童及其父母的 MVPA，减少久坐时间，提高学龄前儿童的身体素质。总体而言，本研究设计的基于智能手机应用程序的学龄前儿童家庭亲子 PA 干预模式是可行且有效的。
