In the world of sports coaching and skill acquisition, Ecological Dynamics has emerged as a powerful framework for understanding how athletes learn, adapt their movements, and perform on the court. It shifts the focus away from traditional, rigid training methods and instead emphasizes the dynamic interactions between the player and their environment.
It’s a theory to make sense of human movement and how humans move. Professor Keith Davids is widely regarded as one of the founding figures of this approach. Keith’s research in the early 2000’s started challenging everything we knew about how the human body works and how athletes learn. Keith and colleagues draw upon research from two different fields to create an ecological dynamics framework:
Dynamical Systems Theory + Ecological Psychology
This is a great diagram from Alex Sarama’s book, explaining the key terms within both fields.
Self-organization is a key part of dynamical systems theory. Instead of players following pre-programmed movements, self-organization is the idea that basketball players organize their bodies naturally to solve movement problems. In other words, they are not recalling stored techniques in the brain in order to move. The irony is that many coaches coach their players out of effective self-organizational techniques by trying to impart “the correct technique.”
Perception-action coupling comes from ecological psychology. It’s the idea that perception informs action, and action is always shaping perception. This continuous loop is crucial for a player’s interactions within the game environment.
So where does the The Constraints-Led Approach (CLA) come in?
A CLA is a way of coaching that is based upon an ecological dynamics framework. Therefore, you have to understand an ecological approach if you want to be an effective CLA coach.
A CLA challenges traditional coaching methods that rely heavily on isolated drills and repetition without context. Instead, using CLA principles means creating “representative” learning environments where players experience live opponents to develop their skills effectively.
The Role of the Coach in Practice
An ecological approach has implications for the role of the coach in practice. The coach’s job is to design activities which contain specific affordances. An affordance is, simply put, an opportunity for action. The coach manipulates the constraints (see Newell’s constraints model below) to create varied affordances for the players to act on. The idea of constraints is that they may make some affordances enticing, and some less so!
By manipulating constraints, it creates varied environments for the players to perceive and act on the new affordances that present themselves.
An effective CLA coach manipulates constraints well enough so that players are seeing the attractive affordance available to them, while finding ways to act upon them with functional solutions. A common misconception of a CLA is that the coach just creates live games and let’s anything happen. This couldn’t be further from the truth!
These five principles can be effective in helping you use a CLA in your next practice…
Ecological dynamics offers a more holistic way of understanding skill acquisition in basketball and other sports. Coaches who embrace this approach can help athletes develop the ability to perceive and act in dynamic environments—just like the game itself demands.
