However, limited studies had investigated the occurrence and risk factors of running injuries among Taiwan runners. The purpose of this study was to investigate the occurrence of running-related injuries in lower extremity, and to evaluate the possible risk factors linking to these injuries. Subjects and methods: This was a cross sectional study. All participants of 2015 Agongdian Marathon, including full marathon (42.195 km, 3000 runners), ultra-half marathon (24 km, 3000 runners), and leisure group (7 km, 1000 runners), were invited to complete a questionnaire on personal characteristics running and training conditions, and injury profiles. The collected data were analyzed by using Chi-square statistics and multivariate logistic regression models to examine the possible relationship between the injuries of lower extremity and various possible variables. Results: There were 856 runners consented to participate this study on the event day. After excluding subjects with incomplete data, a total of 830 individuals were included in this study. Among the 830 runners, 579 (69.82%) reported having previous lower extremities pain related to running and 436 (52.5%) had multiple injuries. The most common site of injury was the knee (28.5% of the total injuries). Other common sites were the ankle/foot (23.7%), lower leg (18.8%), thigh (15.6%), and pelvis/hip (15.0%). Higher rate of knee pain was found in runners with genu varum, and higher rate ankle/foot injuries was found in flat-foot runners. Previous lower extremities injury was associated with most injuries of lower extremity. Runners with running experiences 3-5 years had more knee pain. Runners with running on asphalt road had more knee pain than on artificial lanes. More runners with knee pain used knee braces, and more runners with leg pain used compression calf sleeves. There were significant relationships between joining a running group and pelvis/hip or ankle/foot injuries. Continued training after having injured was a important risk factor of all lower extremity injuries and multiple injuries. Conclusion: This study investigated running-related injuries of lower extremity and reported some risk factors linking to injuries. For marathon and road-race runners, this information can be used in developing strategies to arrange training programs, prevent running associated injuries and develop more effective treatment programs.
