active ▁have ▁poor ▁health , ▁but ▁they ▁also ▁have ▁poor ▁cogn itive ▁health ▁also . ▁With ▁low ▁fit ness ▁there ▁is ▁a ▁relationship ▁to ▁decre ased ▁cogn itive ▁function ing ; ▁for ▁instance ▁there ▁are ▁different ▁types ▁of ▁cogn itive ▁problems ▁like ▁per ception , ▁memory , ▁cogn itive ▁control , ▁and ▁there ▁is ▁lower ▁academic ▁achiev ement . ▁Many ▁tests ▁have ▁been ▁conducted ▁to ▁identify ▁what ▁exactly ▁is ▁the ▁reduction ▁when ▁children ▁do ▁not ▁have ▁physical ▁activity . ▁One ▁test ▁selected ▁children ▁to ▁be ▁in ▁two ▁different ▁groups , ▁one ▁group ▁was ▁phys ically ▁active ▁the ▁other ▁group ▁was ▁not . ▁After ▁a ▁while ▁of ▁monitoring ▁the ▁children ▁the ▁research ers ▁tested ▁the ▁children ▁in ▁learning ▁and ▁recall ▁memory ▁to ▁see ▁what ▁they ▁were ▁retain ing ▁and ▁to ▁observe ▁the ▁difference ▁if ▁available ▁of ▁low ▁physical ▁activity ▁versus ▁high ▁physical ▁activity . ▁The ▁results ▁came ▁back ▁indicating ▁that ▁the ▁children ▁without ▁physical ▁activity ▁have ▁a ▁later ▁recall ▁process ▁than ▁the ▁children ▁with ▁physical ▁activity . ▁The ▁learning ▁part ▁of ▁the ▁experiment ▁was ▁equally ▁distributed ▁on ▁both ▁spectrum s ▁for ▁each ▁group , ▁but ▁recall ▁memory ▁was ▁the ▁only ▁variable ▁that ▁did ▁not ▁match ▁both ▁of ▁the ▁groups . ▁▁ <0x09> Phys ical ▁activity ▁has ▁a ▁significant ▁influence ▁on ▁the ▁hi pp oc amp us , ▁since ▁this ▁is ▁the ▁part ▁of ▁the ▁brain ▁that ▁is ▁responsible ▁for ▁encoding ▁information ▁into ▁memory . ▁With ▁physical ▁activity ▁having ▁such ▁an ▁impact ▁on ▁the ▁hi pp oc amp us ▁this ▁can ▁reg ulate ▁other ▁parts
