Conclusions
Among the several interventions that can use physical activity and watching the natural environment to promote the recovery of attention levels during children’s recess, the effect of improving their attention level is the best after physical activity intervention and watching natural environment videos. Moreover, this study found that arranging physical activity interventions in the second half of children’s recess will affect their attention, particularly the visual attention level, at the beginning of class. Therefore, this study recommends not to arrange children’s physical activity intervention in the second half of the class break. Moreover, we recommend to arrange the content of physical activity intervention first and further improve their attention further by watching natural environment videos.Among interventions using physical activity and natural environment viewing to promote recovery of attention levels, important individual factors are age, weekly physical activity frequency, duration of each physical activity, weekly natural environment video or picture viewing frequency, duration of each nature video viewing, mother’s education level, and daily attention level. Future research in this field should focus on the influence of individual factors on young children’s attention and strengthen the adjustment of related covariates.
