Organismic Constraint

Constraints are boundaries that limit the movement capabilities of an individual, there are three distinct categories, organismic (individual), environmental, and tasks constraints. Organismic constraints have have two different parts, structural and functional components. The structural component of an organismic constraint has three parts, body attributes (body weight, height), cardiovascular endurance (think of it as if you were told to run a marathon just to get an A on a test without any prior training), and flexibility/mobility. The functional component of an organismic constraint also has three parts the fear, personality, and motivation in a subject. Environmental constraints are factors which must be taken into account that influence performance. It is easier to think of this as performance context
The rules is the movement patterns and technique boundaries. What is implemented is the size, dynamics and weight of object presented. Organismic, Environmental, and Task constraint all interact with one another to encourage behavior.
When using the constraint model two people may perform very differently in the same movement situation. The constraint approach is how learners search through range of potential movement solutions. Also, the perceptual motor workspace, which is the use of perceptual cues to identify a space. For example, if two early childhood aged kindergartners were seated at a table (space) and told to pick up a full glass of water they may perceive it and act differently. The two kindergarteners, one boy and one girl, the boy is tall for his age and has brown short hair and the girl has blonde hair and is short and does not have a right hand. Each child is told to sit at the table at different times and told to pick up the full glass of water. The boy may quickly pick it up fast because he is excited and thinks it is a competition. The support of the table gives him the mobility to reach for the glass and do what he is asked to do. The
