Decision making in sport involves forecasting and selecting choices from different options of action, care, or management. These processes are conditioned by the available information (sometimes limited, fallible, or excessive), the cognitive limitations of the decision-maker (heuristics and biases), the finite amount of available time to make the...

In this final chapter, we ask the members of our performance panel to variously discuss how they plan to use data over the next bi cycle in their sport, or how they will continue to draw inspiration from others in refining their own process. We also ask if we are close to seeing data modelling for injury in the near future.

Performance in team sports is the expression of complex, dynamic, interactive and multidimensional processes. It is now well-established that optimum recovery after practice or match is a key factor of team sport performance. During season and tournaments, improving recovery could offer an advantage for following performance. As a consequence of th...
