The Street Workout ACadEmy (ACE) project aims to better the prevention of injuries for street workout practitioners and young people by creating and testing an innovative training program for street workout coaches. This sport is mostly self-though and there is no coach’s (trainer’s) license, so the people practicing it have no mandatory education on injury prevention and this is where this project comes into play. Trying to protect the athletes by improving training conditions, the project aims, among other things, at training coaches, raising awareness of injury prevention techniques, developing a training program for street workout coaches with a focus on safety for young athletes and prevention of injuries during training. As a result, the competencies of coaches practicing Street Workout in Bulgaria, Romania and Croatia will be increased, which will lead to safer practice of the sport and increase its popularity.
