Instead of thinking about the actions at each joint in clumsily performing a new skill, a child may soon be able to smoothly coordinate the joint actions and simply think about performing a single action. For example, some children may be able to step and hop, the two basic components of the skip, but unless they are able to coordinate the timing of the two skills in both legs, they will not be able to perform this fundamental movement skill. However, a child suddenly may be able to skip as his/her maturing nervous system allows him/her to build larger and more complex coordinated units of action.
Make Adjustable with Environment
Environmental factors may also influence the emergence of movement skills. The motivation to move may be enhanced by exposing children to environmental features that invite action, such as interesting objects and toys, accommodating surfaces and terrains, playful siblings and friends, and attentive caregivers. Improving attractiveness and increasing opportunities to move may advance early locomotors milestones and in later years, many are the most important factor in a child becoming proficient at specialized movement skills.
Actively Explore the Environment
ADVERTISEMENTS:
Limited opportunities to actively explore the environment and participate in movement activities may delay or deny a child’s acquisition of certain movement skills. For example, a researcher recently reported that infants who spent more than two hours a day in walkers crawled and crept significantly later than other infants. It should be emphasized, however, that the long-term effect of this type of experience is unknown.
Take Care of Physique and Growth
Performer factors which are most likely to affect the emergence of particular movement skills include body size and physical growth, strength relative to body weight, and the maturity of the nervous system. Research about body size shows that children with proportionately longer legs, who are not overweight, tend to walk earlier than children with shorter legs. Degree of strength is illustrated by jumping or hopping, which requires children to have at least enough strength to project their bodies off the ground.
Nervous System should not be disturbed
ADVERTISEMENTS:
Most motor development experts view the maturity of the nervous system as the primary factor in effective use of movement skills in children. The greatest problem for the developing nervous system is to control the many separate action units, of the body. In one arm alone, excluding the hand, there are approximately 2,600 motor units, 26 muscles, and 4 joints. Through learning and maturation, independent action units become coordinated, reducing the need to control individual units.
