What Are The Three Main Categories Of Constraints

Constraints are an important to the self-organization of human movements. There are three main categories of constraints. The categories are, individual, task, and environment. Together these three categories help us understand how coordinated movements are performed.

Environmental constraints are physical variables that occur in nature. For curling this can be the amount of ambient light that the venue has. Environmental constraints can also be social, instead of physical. An example would be the amount of noise that the crowd is producing. The type of noise can also play a factor. For example, the crowd can be cheering for or against the team that is sending the stone down the sheet of ice. Curling is a sport that is played within a building complex. As a result, temperature of the building can have an affect on the ice runway. This can greatly effect how contestants perform. …show more content…
Stone dimensions as well as the shoes that are worn by participants are examples of tasks constrains. The rules of the sport of curling can also be considered a task constraint. One of the rules allowed in curling is that you can hit opponent’s stones out of the target area. This can play a big role when it comes to scoring and strategy. Equipment used also qualifies as a task constraint. The main equipment used in curling is the stone, slider shoes, gripper shoes, and a brush. The stone is the object that is thrown down the sheet of ice. Slider shoes help the curler that is delivering the stone. The curlers that are brushing the ice wear gripper shoes. Finally, the brush is used to help brush the ice. This is done to remove anything in the path of the stone as well as reduced
