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.

Background: Observational learning is an effective pedagogical approach that can be used as a method to improve motor skill acquisition and also a useful instrument to promote psychological variables such as self-efficacy by emphasizing the motivational aspect. Although, little research is known about the model type and the observation conditions which will optimize learning. Aim: This study aimed to clarify the effect of using a combination of ideal model-observation and self-observation on self-efficacy and learning the forehand service of table tennis. Materials and Methods: Forty females were assigned to one of four experimental groups. All groups received the same instructions concerning how to perform the task, filled out a self-efficacy questionnaire, and then performed 10 pre-test trials. The acquisition phase included six sessions. The retention test was done 72 hours after the last acquisition session. Mixed ANOVA with repeated measures and Bonferroni post hoc tests were conducted, and one-way ANOVA was used to determine group significant differences. Results: The results indicated that observing the combination of skilled and learning models led to the highest self-efficacy for learning, compare with other experimental models. Also, significant learning of the task was shown in the acquisition phase in which the performance of all three experimental groups was clearly superior to the control group. Although in this phase there was no significant difference between the performances of two groups of combined skilled-learning and skilled. The results of the delayed retention test indicated that the performance scores of the combined skilled-learning group were significantly higher than the other three groups. Also, in this phase, the difference between the combined skilled self-observation and control or skilled groups was not significant. Conclusion: Demonstrating a skilled model is the most popular type of observational learning among the instructors and physical education teachers, it is suggested that adding a learning model to that leads to better performance and enhancing the self-efficacy.
