Classroom-based physical activity breaks are suggested to positively impact children's attention during their school day. Frequency and time implications are important as decisive factors in structuring primary school active break programs. The purpose of the study was to research the influence of frequency and time implications on efficacy of primary school active break programs. Materials and methods. This academic survey was admitted as the first Algerian pilot research among primary schools. Its appointment aims are to test the effect of frequency and time implications as decisive factors in structuring primary school active break programs. 4 teachers and 5-grade class levels took part in the study. A total of 180 children (100 girls and 80 boys), 45 in each class were involved in the study. The average age of the participants was 10.4±0.61 years old. All participants provided their written consent to attend the study. The ethics committee of Physical Education Institute, University of Abdel Hamid Ibn Badis Mostaganem had also given its approval. All children were divided in four groups. Group 1 (20 boys and 25 girls) had 2 minutes of exercise every 20 minutes of siting. Group 2 (19 boys and 26 girls) had 6 minutes of exercise for every 1-hour of sitting. Group 3 (19 boys and 26 girls) had 9-minute traditional Active Breaks Classroom-Based Physical Activity program integrated within regular day school break periods. Group 4 was a control one with no Active Breaks Classroom-Based Physical Activity program. All teachers, who voluntarily accepted to be engaged in this experience, were asked to apply the video-based physical activity appropriate for their students according to the model and content (time-frequency) and they encouraged their students to replicate their daily base-physical-activity as proposed. Push, pull, squat, standing chair single-leg balance, flexibility, self-myofascial release and static stretching were used as a complimentary physical activity program. Results and discussion. This study focuses on three frequencies and time implications of proposed Active Break Physical Classroom Routine. The test confirmed the benefits of active breaks program in groups. The higher scores than in the control group were recorded in the post-tests. This study explains it by the complementary time practised by experimental groups according to Active Breaks Classroom-Based Physical Activity program. Clear significant inverse correlations were established between the active-standing time involved and classroom inactive time chair sitting. Conclusion. The results of the study confirmed that it is more useful to use the short break program no longer than 5 minutes, frequently repeated with 2 minutes, after every 20 minutes of prolonged static setting. It has to be used as the prominent strategy for structuring the feasible and potential efficacy of primary school Active Break Program. This model is able to decrease sedentary time and increase daily energy expenditure
