Previous leg injury and use of orthotics/inserts are observed as risk factors for running-related injuries. In addition, men are at higher risk for sustaining running-related injuries compared to women. In recent years, the number of runners and running events has been growing steadily. However, a downside of running is the relatively high risk of injury. Therefore, identifying risk factors needs attention in research. This research may contribute to the development of injury prevention strategies, especially when the risk factors can be influenced by adequate training or by optimizing the training environment.
