Three categories of constraints are considered which discuss shaping technique and tactics with a constraints-led approach.
Performer Constraints: Include physical and mental factors such as height, limb length, strength, speed, technical skills, attentional control and intrinsic motivation. All of these factors can influence decision-making behaviours.
Environmental Constraints: Include physical and cultural environmental constraints. These are constraints outside the body itself and include any physical constraints outside the body, as well as sociocultural constraints.
Task Constraints: Include the goal of the task, rules of the game, equipment available and the relative state of the game.
