Background: This paper aimed to assess the development process, content, and early implementation of Oman’s national physical activity plan of action to identify strengths and areas for improvement. Methods: Data were extracted from 4 documents: national noncommunicable diseases policy, physical activity plan of action, and 2 World Health Organization Mission Reports. Three policy frameworks and approaches (physical activity content analysis grid, health-enhancing physical activity policy audit tool, and policy cube approach for diet-related noncommunicable diseases) were used. Results: The findings demonstrated that policymakers engaged a broad range of sectors in developing a national plan. It aligned with many of the elements from the 3 policy frameworks (ie, multisectoral approach, political commitment/leadership, identification of national goals and targets, time frame for implementation). The main gaps included the lack of a specified sustainable funding mechanism, systems for monitoring progress, and an emphasis on general interventions, with limited focus on specific target groups. Conclusion: A range of sectors were engaged in the development of Oman’s national physical activity plan of action, with strong political commitment and using global guidance and local evidence. Establishing a strong accountability framework, including a clear financing mechanism, is critical for Oman to meet its target for a 10% relative reduction in physical inactivity by 2025.
