Physical Education (PJOK) plays a crucial role in developing elementary school students’ fundamental motor skills, particularly locomotor abilities such as running, jumping, hopping, and coordinated directional movement. However, limited variation and monotonous instructional approaches often reduce students’ active engagement, potentially hindering optimal motor development. This study aimed to analyze the effect of the traditional Boy game on the locomotor skills of students at SDK Wolowio. This research employed a quantitative true experimental method using a pretest–posttest control group design. A total of 50 students were divided into an experimental group (n = 25) and a control group (n = 25). The experimental group received structured physical education instruction integrating the traditional Boy game for eight sessions, while the control group participated in conventional instruction. Locomotor ability was measured through standardized tests assessing speed (20-meter sprint), agility (change-of-direction test), and coordination (locomotor movement circuit). Data were analyzed using paired and independent sample t-tests at a significance level of 0.05. The results showed that the experimental group’s mean score increased significantly from 58.40 to 78.32 (gain = 19.92; p < 0.05), while the control group improved from 57.96 to 63.88 (gain = 5.92; p < 0.05). Posttest comparisons revealed a significant difference between groups (p < 0.05). In conclusion, the traditional Boy game significantly enhances elementary students’ locomotor skills and serves as an effective, culturally relevant instructional model in physical education.
