Zoning on the vertical plane as a "visual target"

Constraints are internal or external boundaries, limitations, or design features that restrict the number of possible configurations that the many degrees of freedom of a complex system can adapt (Glazier, 2015. Towards a Grand Unified Theory of Sports Performance).

Constraints are not used randomly, but in a systematic and intentional way, with a specific learning outcome in mind. Constraints set the boundaries for the most functional movement solutions, so making changes to constraints directs learning to new solutions. The chosen constraints invite (afford) certain behaviours, while excluding others.

In other words, actions are not caused by constraints; rather, some actions are excluded by constraints. On that note, how can we invite more attacking shots in net barrier games such that the shots are not high and slow, but instead, low and fast, or downwards whenever possible? In this illustration, I have explored with a different way to utilise the idea of "zoning", this time on the vertical plane instead. Two net lines are used as part of the constraints. Hope the illustration makes sense. Have fun trying! Note: "code red" and "code green" are further modifications to differentiate learning.
