Reducing difficulty from high to moderate is achieved through task simplification rather than decomposition to maintain skill aspects. It is essential to uphold action fidelity, perception-action coupling, and provide performance information similar to that in competition. Uncertain conditions in practice engage performers and prepare them for competition scenarios with blurred vision or damaged playing surfaces. These conditions can be created through changes in ball size, field size, or surface, known as constraints manipulations. While different goals are needed for various practice sessions, all goals should focus on achieving skill mastery.
