Introduction: The COVID-19 pandemic allowed us to test the relationship between lifestyle changes and children's motor proficiency level, And by preventing the decrease in movement skills, we should predict the necessary programs to improve the health of children and students during epidemics. The purpose of this research was to investigate the relationship between physical activity and nutritional knowledge with body mass index (BMI) and motor skills of girls aged 10 to 14 years in schools in Khanaqin during the Corona era. Materials & Methods: The research was correlational-descriptive with a cross-sectional way, the statistical population was selected girls aged 10 to 14 years in schools in Khanaqin city, Based on the Cochran formula, 350 individuals were randomly selected as the research sample. Data collected by three standard questionnaires, Bruininks Oseretsky test-Short Form (BOT-2), the International Physical Activity Questionnaire (IPAQ), and the eating habits questionnaire of Paramenter and Wardell (1999). Data analysis was carried out by using Pearson’s correlation coefficient. Results: The results showed that physical activity correlated negatively (r=-0.29, p=0.01) with BMI and correlated positively with motor proficiency (r= 0.213, p=0.05), but there is no significant relationship between nutritional knowledge with BMI and motor proficiency of girls aged 10 to 14 years old in the schools of Khanaqin during the Corona era (P>0.05). Conclusion: According to the obtained results, it can be concluded that physical activity during the Corona period improves the BMI and motor skills in girls. Therefore, to have a positive effect on motor skills, it is necessary to choose appropriate physical activities according to the situation and perform them regularly. Consequently, parents played a greater role in preventing the deterioration of children's motor skills during the pandemic.
