The LEG program promotes the development of physical activity and fundamental movement skills in preschool children aged 3-6 years: a Delphi study.

Background: Effectively addressing physical inactivity and the delayed development of fundamental movement skills in preschool children aged 3-6 years.

Methods: We assembled an interdisciplinary team of experts to systematically validate the LEG program indicators using the Delphi method. This Delphi study thoroughly and meticulously explored the insights of experts in the field to identify the necessary indicators of the LEG program's role in promoting the sustainable development of physical activity and fundamental movement skills in preschoolers aged 3-6. Using a 5-point Likert scale and Wilcoxon statistical techniques, this study examines the dynamic consensus among experts and elucidates potential differences in their views.

Results: After three rounds of Delphi surveys, O1, O2, and O3 reached consensus in all three rounds. T5, I5, I14, C11, and C12 disagreed due to disciplinary differences, while C18 and C22 disagreed due to cultural differences. Finally, the LEG program indicators achieved consensus on three objectives, seven tasks, 17 indicators, and 25 content areas. The results of this study strongly convey the experts' positive perceptions of the LEG program indicators in promoting sustainable development of physical activity and fundamental movement skills in preschoolers aged 3-6 years.

Conclusion: This indicates that the LEG-structured curriculum indicators we developed are scientific and reliable, aligning with the physical and mental development of preschoolers aged 3-6 years. This understanding fosters the in-depth integration of early childhood physical education and preschool education, providing a foundation for enhancing the sustainable development of physical activity and fundamental movement skills among preschoolers aged 3-6 years.
