Document Summary

School age children in us gain (cid:554)-(cid:555) inches and (cid:557)-(cid:559) pounds per (cid:297)ear. At the age of (cid:559), the a(cid:290)erage american child (cid:606)both bo(cid:297) and girl(cid:607) is (cid:556) feet tall. Gender differences as adolescent gro(cid:291)th spurt begins. Girls more bod(cid:297) fat in middle childhood. Regularl(cid:297) used s(cid:297)napses are strengthened and unused s(cid:297)napses are pruned. Dendrites and a(cid:296)ons are still gro(cid:291)ing and branching out causing the creation. Running, jumping, hopping, thro(cid:291)ing and catching a ball are gross motor skills that become more refined in middle childhood. V(cid:296)periences at home and at school influence this de(cid:290)elopment. V(cid:296)perts recommend that these children get at least (cid:553) hour of ph(cid:297)sical. Most kids onl(cid:297) get about half of this. acti(cid:290)it(cid:297) a da(cid:297). Accidents still the leading cause of death at this stage of life. One in e(cid:290)er(cid:297) three children (cid:606)(cid:555)(cid:553). (cid:559)%(cid:607) ages (cid:554)-(cid:553)(cid:561) is o(cid:290)er(cid:291)eight or obese. Obesit(cid:297) is estimated to cause (cid:553)(cid:553)(cid:554),(cid:552)(cid:552)(cid:552) deaths per (cid:297)ear in the united states.
