Za hojo, dvigovanje predmetov in vzpenjanje po stopnicah se zana\u0161amo na svoje mi\u0161ice. V vesolju pa mi\u0161ice oslabijo, saj ni treba premagovati gravitacije. Ko se astronavti vrnejo na Zemljo, kjer vlada obi\u010dajna gravitacija, se nenadoma po\u010dutijo zelo te\u017eki in te\u017eko ohranjajo ravnote\u017eje. Podobni u\u010dinki se pojavljajo tudi pri starej\u0161ih ljudeh in tistih, ki zaradi bolezni dolgo \u010dasa pre\u017eivijo v postelji.<\/p>\n<\/div>\n

Raziskave vesolja ponujajo prilo\u017enost, da se bolje seznanimo z u\u010dinki dolgotrajnega mi\u0161i\u010dnega izgubljanja.<\/p>\n

Testi z astronavti so pokazali, da je za prepre\u010devanje mi\u0161i\u010dne oslabelosti potrebnih nekaj ur dnevne vadbe. Med napravami, ki se uporabljajo v vesolju, so tekalne steze za tek na mestu in sobna kolesa. Te so pomembne za krepitev mi\u0161ic in izbolj\u0161anje krvnega obtoka.<\/p>\n

Astronavti lahko nosijo tudi posebne hla\u010de, ki usmerjajo kri v noge in spodbujajo mo\u010dnej\u0161e \u010drpanje srca. Ti in drugi ukrepi, kot je zdravljenje z zdravili, imajo potencialne koristi tudi za bolnike na Zemlji.<\/p>\n

Eden od novih naprav, ki jih razvija ESA, je vadbna naprava \u00bbFlywheel\u00ab. Ta vklju\u010duje vrte\u010de se kolo in se lahko uporablja za vadbo tako v vesolju kot na Zemlji. Februarja 2008 je bil skupaj z laboratorijem Columbus agencije ESA izstreljen na Mednarodno vesoljsko postajo, kjer se uporablja kot napredna naprava za vadbo astronavtov. S\u010dasoma bo na voljo tudi za rehabilitacijo bolnikov in za trening \u0161portnikov.<\/p>","protected":false},"excerpt":{"rendered":"
