Abstract
Abstract
Objective
To investigate the “supercompensation” effect of preschoolers during the coronavirus disease 2019 lockdown by comparing the changes in physical activity (PA), psychological, and sleep indicators before and after the lockdown.
Methods
A total of 127 children (aged 3–6 years) were recruited. Before and after the lockdown, the children’s PA levels were measured using the ActiGraph GT3X+, and their psychological and sleep indicators were measured using the Strengths and Difficulties Questionnaire (SDQ) and Child Sleep Habit Questionnaire (CSHQ), respectively.
Results
Regarding PA, the children’s total physical activity, low-intensity physical activity, and medium-intensity physical activity (MVPA) were higher after the lockdown than before the lockdown, with significant differences in MVPA (p < 0.05). Regarding psychology, the children’s SDQ and multidimensional scores were better after the lockdown than before the lockdown, with a significant difference in SDQ scores (p < 0.05). Regarding sleep, the children’s CSHQ scores were better after the lockdown than before the lockdown, with a highly significant difference in CSHQ scores (p < 0.01).
Conclusion
After lockdown, children’s PA, psychological, and sleep effects were “supercompensated.” In particular, the PA of preschoolers before, during, and after the lockdown may show a “baseline-inhibition-supercompensation” process.
