Background: The present research was conducted regarding the prediction of socio-cultural and individual restrictions on the amount of regular physical activity in female people during the outbreak of covid-19.Aims: The present study was conducted with the aim of predicting socio-cultural and individual constraints to regular physical activity in youth during the outbreak of covid-19.Materials and Methods: This research is descriptive correlational research. 371 females with an average age of 24.27±0.17 years, participated via a random method. Questionnaire based on Basnef model constructs and the International Physical Activity Questionnaire (IPAQ) were used to collect data. Data were analyzed using Chi-square, logistic regression, and linear regression tests.Results: The research findings indicate that there is a significant relationship between background variables and regular physical activity. Subjective norms, behavioral intention, and enabling factors (characteristics of sports facilities and equipment) were considered important predictors of regular physical activity among female people. Also, subjective norms and attitudes (participation motivation) affect the behavioral intention of doing physical activity in young people.Conclusion: Therefore, it is recommended that education officials in universities, anticipate the necessary infrastructure to provide sports halls, equipment, and suitable facilities in order to improve the level of physical activity in young people. Furthermore, families identify their sport activity interests and as much as possible support them financially and spiritually. Young people also should do weekly physical activities by forming friendly groups such as being members of student sports teams.
