Cercetarea, realizat\u0103 de o echip\u0103 de la Facultatea de Medicin\u0103 a Universit\u0103\u0163ii Harvard \u015fi publicat\u0103 \u00een luni, \u00een prestigioasa revist\u0103 Nature Medicine<\/a>, sugereaz\u0103 c\u0103 nu este nevoie de pragul de 10.000 de pa\u015fi pe zi pentru a ob\u0163ine beneficii cognitive. Chiar \u015fi mi\u015fcarea moderat\u0103 poate avea efecte notabile asupra s\u0103n\u0103t\u0103\u0163ii creierului, scrie News.<\/a><\/p>\n\n\n\n

Studiul a inclus 296 de participan\u0163i din programul Harvard Aging Brain Study, care urm\u0103re\u015fte etapele incipiente ale bolii Alzheimer.<\/p>\n\n\n\n

Niciunul dintre participan\u0163i nu prezenta semne de afectare cognitiv\u0103 la \u00eenceputul cercet\u0103rii.<\/p>\n\n\n\n

Timp de p\u00e2n\u0103 la 14 ani, ace\u015ftia au fost evalua\u0163i periodic prin teste cognitive \u015fi investiga\u0163ii imagistice cerebrale, purt\u00e2nd pedometre pentru a m\u0103sura num\u0103rul mediu de pa\u015fi zilnici.<\/p>\n\n\n\n

Creierul persoanelor cu risc crescut de Alzheimer prezint\u0103 de obicei acumul\u0103ri anormale de proteine beta-amiloid \u015fi tau. De\u015fi mecanismul exact dintre cele dou\u0103 nu este complet \u00een\u0163eles, se \u015ftie c\u0103 nivelurile de beta-amiloid cresc primele, fiind urmate de acumularea proteinei tau, asociat\u0103 mai direct cu declinul cognitiv.<\/p>\n\n\n\n

Rezultatele au ar\u0103tat c\u0103 beneficiile mi\u015fc\u0103rii zilnice s-au manifestat doar la persoanele care aveau deja niveluri ridicate de beta-amiloid, adic\u0103 \u00een stadiile preclinice ale bolii.<\/p>\n\n\n\n

La aceste persoane, activitatea fizic\u0103 a redus ritmul de acumulare a proteinei tau, responsabil\u0103 de deteriorarea conexiunilor neuronale, \u00eencetinind astfel declinul cognitiv cu 3 p\u00e2n\u0103 la 7 ani comparativ cu persoanele sedentare. \u00cen schimb, acumularea de beta-amiloid a continuat, f\u0103r\u0103 modific\u0103ri majore.<\/p>\n\n\n\n

Pentru participan\u0163ii cu niveluri sc\u0103zute de beta-amiloid, adic\u0103 cu risc sc\u0103zut de Alzheimer, num\u0103rul de pa\u015fi nu a influen\u0163at semnificativ performan\u0163ele cognitive.<\/a><\/p>\n\n\n\n

Autorii subliniaz\u0103 c\u0103 persoanele cele mai expuse declinului cognitiv sunt cele cu niveluri ridicate de beta-amiloid \u015fi activitate fizic\u0103 sc\u0103zut\u0103, o categorie care ar trebui vizat\u0103 prioritar<\/a> prin interven\u0163ii pentru a evita sedentarismul.<\/p>\n\n\n\n

Concluzia studiului este \u00eencurajatoare: chiar \u015fi un nivel redus de activitate fizic\u0103, u\u015for de atins pentru majoritatea v\u00e2rstnicilor, poate contribui semnificativ la men\u0163inerea func\u0163iilor cognitive \u015fi la \u00eencetinirea progresiei bolii Alzheimer.<\/p>\n\n\n\n
