Intervention of Modified Physical Activity Model on Symbol Test Abilities of Elementary School Students

Abstract

Regular physical activity, especially moderate to vigorous physical activity (MVPA), has been proven to have positive effects on memory function. This is due to the significant influence of physical activity on brain function. Several studies indicate that physical activity optimizes brain development, especially in school-aged children who are still growing. The method used in this research is a two-step research design. Firstly, a Research and Development approach will be utilized to prepare and develop a moderate physical activity program suitable for elementary school children. Secondly, an Experimental Group Design will be employed to investigate the effects of physical activity on brain function. Researchers administered a "Digit Symbol Test” to experimental groups before and after the physical activity. The “Digit Symbol Test” is completed within 90 seconds, and students are required to complete as many as possible within their ability. The results indicate that the scores after the physical activity intervention tend to increase compared to the scores before the physical activity. The highest score increase is 27 points, with an average score increase of 9 points. These results are also consistent with previous studies and will challenge the perspective of parents who believe that physical activity before lessons begin has a negative impact on the learning process. This research proves that physical activity conducted before the start of lessons has a beneficial effect on students' brain function.
