The cognition-dynamics interface and performance in sport

This commentary focuses on the relationship between intentions and actions, ns within theoretical models of movement behaviour considered in relation t o sport performance. It is argued that an integrated approach is needed whi ch seeks to explain intentionality as one of many important constraints on movement systems, An interesting question is whether complementarity is nee ded in models of the intentions-actions relations. it is recognised that an overarching dynamical systems approach is working towards the goal of inte grating the behaviour of cognitive and movement systems. The emphasis on co nstraints within a unified, non-complementary framework, as well as a poten tial strategy for sport pedagogy.
