The introduction of strict quarantine restrictions in many countries initiated a direction in science to study the behavioral characteristics of children and adolescents during the social isolation at the population level. We present our observations during the two lockdowns in Ukraine. The objective of this study was to determine: a) the level of light (LPA) and moderate-to-vigorous (MVPA) physical activity among school-age children, and b) the impact of the external and internal factors on their physical activity during the lockdown. Global Physical Activity Questionnaire (GPAQ) as part of our questionnaire Q-RAPH was used. Parents of 1091 children 6–18 years old (54% boys) filled Q-RAPH at two measurement points in 2020 and 2021. After performing ANCOVA and logistic regression, we found a significant decrease in MVPA by 12.7% in 2021 compared to 2020 (p < 0.001) while LPA was about 1.5 h a day during both periods. The proportion of children who reach the recommended levels of MVPA also decreased by 13.7% in 2021 (p < 0.001). Factors negatively affecting the achievement of 60 min a day of MVPA were female gender, chronic diseases, overweight/obesity, non-participation in organized sports, and a decrease in the average air temperature. This study evidences the insufficient level of preventive measures and requires an intensification of health education among the Ukrainian population. When developing preventive measures, special attention should be paid to groups vulnerable to MVPA reduction as children who have chronic diseases and/or overweight/obesity as well as non-participation in sports.
