Vet du vad som h\u00e4nder med din kropp om du ligger i en lutande s\u00e4ng i flera veckor med huvudet i den nedre \u00e4nden? Din kropp b\u00f6rjar f\u00f6r\u00e4ndras som om den \u00e5ldrades i f\u00f6rtid\u2026 eller levde i rymden!<\/p>\n<\/div>\n

Tolv personer deltar i en ESA-studie som g\u00e5r ut p\u00e5 att ligga i s\u00e4ngen med huvudet 6 grader l\u00e4gre \u00e4n resten av kroppen under 21 dagar. Regeln \u00e4r att h\u00f6fterna och minst en axel m\u00e5ste vara i kontakt med s\u00e4ngen hela tiden, \u00e4ven n\u00e4r de \u00e4ter, tv\u00e4ttar sig och g\u00e5r p\u00e5 toaletten.<\/p>\n

Allteftersom deras muskler f\u00f6rsvagas \u2013 en deltagare har g\u00e5tt ner n\u00e4stan fyra kilo \u2013 \u00f6vervakar v\u00e5rdpersonalen dem noggrant. Forskarna vill unders\u00f6ka om tr\u00e4ning och\/eller proteintillskott har n\u00e5gon inverkan p\u00e5 f\u00f6rs\u00f6kspersonernas fysiska h\u00e4lsa, eftersom detta kommer att hj\u00e4lpa dem att ta hand om astronauterna n\u00e4r de befinner sig i rymden.<\/p>\n

F\u00f6r detta experiment har de delat in f\u00f6rs\u00f6kspersonerna i tre grupper. Tv\u00e5 av dessa grupper genomf\u00f6r ett kort, intensivt tr\u00e4ningspass p\u00e5 en vibrationsplatta som tr\u00e4nar benmusklerna. Tr\u00e4ningspasset upprepas var tredje dag. En av dessa tv\u00e5 tr\u00e4ningsgrupper intar dessutom proteintillskott av den typ som kroppsbyggare anv\u00e4nder f\u00f6r att \u00f6ka sin muskelmassa.<\/p>\n

Den tredje gruppen tr\u00e4nar inte och tar inga kosttillskott. Den fungerar som en \u2018kontrollgrupp\u2019 och f\u00f6ljs upp f\u00f6r att resultaten ska kunna j\u00e4mf\u00f6ras med de tv\u00e5 andra grupperna.<\/p>\n

De frivilliga genomg\u00e5r regelbundna skanningar, blodprover och muskelbiopsier. De ser fram emot slutet av \u00e5ret, d\u00e5 de kan l\u00e4mna sina lutande s\u00e4ngar f\u00f6r fyra m\u00e5naders rehabilitering. De kommer att \u00e5terv\u00e4nda f\u00f6r ytterligare tv\u00e5 21-dagarsf\u00f6rs\u00f6k, d\u00e4r de varje g\u00e5ng deltar i en annan testgrupp.<\/p>","protected":false},"excerpt":{"rendered":"
