The purpose of this study was twofold; to determine the influence of physically active breaks with video materials during classroom teaching on the students' educational outcomes and to determine the influence of active breaks with video materials on students' attitudes towards physical activity. The study sample was comprised of 38 students from two 3rd grades from primary school Vežica in Rijeka of which 19 students were in experimental group and 19 students were in control group. Variables measured were the influence of physically active breaks on students' academic accomplishments and attitude towards physically active breaks with video materials. Experimental group spent 2 months doing 3-5 min of physical exercise in Math classes between 20th and 25th minute of the class. Before intervention both groups did a standardized Math exam. After the intervention they did another standardized math test, and experimental group additionally filled a questionnaire about their opinions about physical activity. Differences between initial and final measurements in the same group were tested by Student’s Dependent T-test while differences between experimental and control group were tested with Student’s Independent T-test. Results showed that the physically active breaks greatly affect the level of educational achievements of the students, as they equate their knowledge. They also affect students' attitudes as well as their quality of life and at the same time contribute to the integration of different knowledge acquired through the use of video materials. Students learned about the importance of a healthy lifestyle and culture, became more independent and more secure in carrying out their physical activities, while the rest of feedback pointed towards a need for higher-quality video materials. This study showed that physically active breaks with video materials deserve a place in classes and that they should be a part of it. The fact that physically active breaks enrich knowledge, create the habits of healthier life and enhance students independence should be an incentive for us to implement them in each lesson, thus contributing to the student's growth and development both physically and cognitively.
