Tied\u00e4tk\u00f6, mit\u00e4 kehollesi tapahtuu, jos makaat viikkoja kallistetussa s\u00e4ngyss\u00e4 p\u00e4\u00e4 alhaalla? Kehosi alkaa muuttua ik\u00e4\u00e4n kuin se ik\u00e4\u00e4ntyisi ennenaikaisesti\u2026 tai el\u00e4isi avaruudessa!<\/p>\n<\/div>\n

Kaksitoista henkil\u00f6\u00e4 osallistuu ESA:n tutkimukseen, jossa heid\u00e4n on vietett\u00e4v\u00e4 21 p\u00e4iv\u00e4\u00e4 s\u00e4ngyss\u00e4 siten, ett\u00e4 heid\u00e4n p\u00e4\u00e4ns\u00e4 on 6 astetta alempana kuin muu vartalo. S\u00e4\u00e4nt\u00f6n\u00e4 on, ett\u00e4 heid\u00e4n lantionsa ja v\u00e4hint\u00e4\u00e4n yhden olkap\u00e4\u00e4ns\u00e4 on oltava koko ajan kosketuksissa s\u00e4nkyyn, my\u00f6s silloin kun he sy\u00f6v\u00e4t, peseytyv\u00e4t tai k\u00e4yv\u00e4t wc:ss\u00e4.<\/p>\n

Tutkijat haluavat selvitt\u00e4\u00e4, vaikuttavatko liikunta ja\/tai proteiinilis\u00e4t vapaaehtoisten fyysiseen terveyteen, sill\u00e4 t\u00e4m\u00e4 auttaa heit\u00e4 huolehtimaan astronauttien hyvinvoinnista avaruudessa.<\/p>\n

T\u00e4t\u00e4 kokeilua varten vapaaehtoiset on jaettu kolmeen ryhm\u00e4\u00e4n. Kaksi n\u00e4ist\u00e4 ryhmist\u00e4 suorittaa lyhyen ja intensiivisen harjoitusohjelman t\u00e4risev\u00e4ll\u00e4 alustalla, joka treenaa jalkojen lihaksia. Harjoitusohjelma toistetaan kolmen p\u00e4iv\u00e4n v\u00e4lein. Toinen n\u00e4ist\u00e4 kahdesta harjoitusryhm\u00e4st\u00e4 k\u00e4ytt\u00e4\u00e4 lis\u00e4ksi proteiinilis\u00e4ravinteita, joita kehonrakentajat k\u00e4ytt\u00e4v\u00e4t lihasmassan kasvattamiseen.<\/p>\n

Vapaaehtoisille tehd\u00e4\u00e4n s\u00e4\u00e4nn\u00f6llisesti kuvantamistutkimuksia, verikokeita ja lihasbiopsioita. He odottavat innolla vuoden loppua, jolloin he p\u00e4\u00e4sev\u00e4t pois kaltevista s\u00e4ngyist\u00e4\u00e4n nelj\u00e4n kuukauden kuntoutusjakson ajaksi. Sen j\u00e4lkeen he palaavat takaisin kahteen uuteen 21 p\u00e4iv\u00e4n kokeeseen, joissa he osallistuvat joka kerta eri koeryhm\u00e4\u00e4n.<\/p>","protected":false},"excerpt":{"rendered":"
