<![CDATA[Although learning activities generally take place under normal and supportive conditions, it is still necessary to examine whether the anxiety experienced by students is related to changes in heart rate during learning or not. The purpose of this study was to analyze the relationship between psychological anxiety and heart rate during physical activity in students in physical education classes. This study uses a quantitative approach with a cross-sectional correlation design conducted in July 2025 in Semarang. The sampling technique used in this study was purposive sampling for grades 4 and 6 who participated in physical education classes, resulting in a sample of 110 students. The results of the Spearman non-parametric correlation test showed a Sig. (2-tailed) value of 0.000. Because the Sig. (2-tailed) value was less than 0.005, this means that there is a significant relationship between psychological anxiety and heart rate. A correlation of 0.765 means that the strength of the correlation or relationship is very strong. There is a significant relationship and a strong correlation between psychological anxiety and the pulse rate of students during the physical education learning process.]]>
