Abstract
Although physical activity (PA) offers numerous mental and physical health benefits, adult Saudi women face unique social and cultural barriers to participating in PA. This study aimed to explore the motivational factors and obstacles influencing PA participation among adult Saudi women at Taif University. Using Self-Determination Theory (SDT) as the framework, a questionnaire was developed and administered to 706 participants, including students, administrators, and faculty members. Results indicated that psychological motivations were the strongest drivers of PA engagement, while physical and service-related limitations were the primary barriers to regular participation. Notably, women aged 30 to 40 showed a greater inclination toward regular physical activity than other age groups. The results indicate a requirement for focused initiatives and enhancements in infrastructure to overcome obstacles and promote physical activity engagement among women in Saudi Arabia. Further research is needed to validate these findings and to inform strategies for promoting PA among Saudi women.
