Why is it that children throw the way they do? Genetics, extrinsic factors, and size play a role in a child's sequence of events. According to the dynamic systems approach we have rate limiters or controllers that are determined by the child's individual constraints. This is a system that holds back or slows the emergence of motor skill; some children may be slower than others. Body scaling is important when introducing something new, which is making the child's size relative to the size of the equipment or environment being used. In order for the child to develop we must adjust the environment to their skill level. As the child matures and grows, the affordances in the child's life must change too, in order for new movements to be made. It is necessary for adults to interact with their children and encourage them to the best of their ability. It needs to be stressed to a child that it is ok to make mistakes, because that is how we learn and progress. We need to create an environment of success and mentally influence them to continue with their physical performance.
The two common types of throwing for young children are the two-hand underhand throw and the one hand over-arm throw. The one hand over-arm throw can be seen in most sports like baseball, basketball, football, and various others. It is interesting to see the mechanics of the beginning thrower compared to the proficient thrower. Around the age of 3 and up, children can begin to grasp the ball and throw it. When we examine the motor skills at this age we realize the limitations of the use of their body to exert the
