The Development Of The Throwing Movement By Children Aged Five To Seven Based On Newell’s Triangle Model

Throwing as one of the basic components of children’s fundamental motor skills has an influence on the function system and the development of the game. Currently, most of the throwing researches intend to use the isolated constraint design to reveal the developmental sequences of the throwing movement. But movement learning in multidimensional is rare based on interactive factors. This research that based on the Newell’s Triangle Model and in the view of the interactive or non-linear perspective approach discusses the throwing movement in three dimensions [the visible movement, biological movement and sport biomechanics]. Experiment 1 of the study discussd the throwing patterns by children aged five to seven years. Experiment 2 analyzed the throwing movement of coordinate paradigm. Experiment 3 explored the throwing movement in sport biomechanics. Experiments find that:1. Five to seven years old children’s throwing movement model, which is unstable and dynamic is not mature and sensible to the performer attribute, and environmental constraints. Six to seven-year-old children have higher throwing patterns. The footwork and the arm rear are much more mature in a far distance throwing environment2. Body coordination of Children’s throwing movement is affected by performer attribute and environmental constraints. Children intend to slow down their forearm angular velocity in the far distance throwing environment. Five to six years old children aged intend to use their wrist And the boys’ performance is better than the girls’.3. The muscles involved in throwing movement have significant individual differences. Lateral wrist flexor of older children is more active than the younger’s. And the boys intend to use the biceps and lateral wrist flexor, yet the girls intend to use the triceps.4. Performer attribute and environmental constraints are interacted with each other. This interaction has its own radiation effect, which is complicated. The scope of the effect and the time that starts to work has complexity, which can guide children’s throwing movements in different dimension.This present study is based on the multi-constraints explores the developmental sequences of throwing movements in multi-dimension, in order to make a dynamical development concept of throwing patterns, and to provide new ways in teaching fundamental motor skills.
