The first video is of an 11 year old boy named Aaron. In his videos he is considerably faster than the majority of his opponents and seems to have a more proficient form than most of them as well. The second video is of a 5 year old boy involved in coach pitch baseball. Although there is no other batters shown in the video, I would imagine his motor development in swinging a bat is significantly better than his peers. From start to finish this boys swing is smooth and consistent, resulting in impressive hits. The third video is of a 3 year and 11 month old boy. Almost at the age of 4, the boy seems to be at a relatively similar spot that most of his peers would be. The book states that a majority of children demonstrate a mature over arm throwing pattern by 6 years of age and it seems as though this boy is just beginning the development into a mature throwing motion.
At the age of 11, Aaron is very proficient in his movements while running. Although he remains relatively straight up and down while he is running, he performs exceptionally well in most other areas. During takeoff his forward knee comes up higher than his other competitors. He has a longer stride resulting from a greater application of force with each step allowing him to be much faster than his opponents. With each step, his recovery knee is raised high and swings forward quickly while his support leg remains slightly bent at contact and subsequently extends quickly and completely. His arms move in a large arc, in opposition to the leg movements and as his arms come forward, they are bent at the elbows at approximately 90 degrees. One thing that Aaron still needs development with is keeping his arms close to a 90 degree angle as they go back.
At the age of 5, this child has very
