Stages five and six of the TRIPP model require previously assessed laboratory preventive measures (stages three and four) to be put into place in the field and to assess their effectiveness in a real-world context. In a controlled setting like a laboratory, it is very easy to equate and control for factors such as training loads, exposure to interventions, and the like. However, when we move to a real football team, for example, it is now necessary to work within time and workload restrictions from coaches, players, and a timetable that is largely dictated by someone other than the researchers. Moreover, there are other factors that cannot also be controlled, such as the physical environment, player and coach attitudes and opinions, weather and other factors. In the case of implementing a training programme into community-level football teams through the “Preventing Australian Football Injuries through eXercise” (PAFIX) project, it was necessary that the programme incorporated exercises and principles that had been shown to work in the laboratory in both 6- and 12-week training studies into a twenty-eight week periodised programme; that covers the entire season and 8 weeks of pre-season. Firstly, this required progressions of exercises that were achievable by a wide range of player abilities, up-skilling of trainers to deliver those exercises and providing ongoing support to those trainers responsible for implementing the programmes. Secondly, a field test battery needed to be designed to provide surrogate measures of the more complicated laboratory procedures that were not possible to conduct in the field. Though a difficult task, this was achievable by using sound laboratory-based tests, evidence and findings and applying these in the field to track the changes that may occur as a result of the interventions being trialed.
