Vi er afh\u00e6ngige af vores muskler for at kunne g\u00e5, l\u00f8fte genstande og g\u00e5 op ad trapper. I rummet bliver musklerne imidlertid svagere, da der ikke er nogen tyngdekraft at k\u00e6mpe imod. N\u00e5r astronauter vender tilbage til den normale tyngdekraft p\u00e5 Jorden, f\u00f8ler de sig pludselig meget tunge og har sv\u00e6rt ved at holde balancen. Lignende effekter ses hos \u00e6ldre mennesker og hos dem, der ligger i sengen i l\u00e6ngere tid p\u00e5 grund af sygdom.<\/p>\n<\/div>\n

Rumforskning giver mulighed for at l\u00e6re mere om virkningerne af langvarigt muskelsvind.<\/p>\n

Fors\u00f8g med astronauter har vist, at der er behov for flere timers daglig motion for at forebygge muskelsv\u00e6kkelse. Blandt de redskaber, der anvendes i rummet, er l\u00f8beb\u00e5nd til l\u00f8b p\u00e5 stedet og motionscykler. Disse er vigtige for at styrke musklerne og forbedre blodcirkulationen.<\/p>\n

Astronauter kan ogs\u00e5 b\u00e6re specielle bukser, der leder blodet ned i benene og f\u00e5r hjertet til at pumpe kraftigere. Disse og andre tiltag, s\u00e5som medicinsk behandling, kan muligvis ogs\u00e5 anvendes til patienter her p\u00e5 Jorden.<\/p>\n

En ny maskine, der er under udvikling hos ESA, er \u00bbFlywheel Exercise Device\u00ab. Den er udstyret med et roterende hjul og kan bruges til tr\u00e6ning b\u00e5de i rummet og p\u00e5 Jorden. Den blev sendt op til Den Internationale Rumstation sammen med ESAs Columbus-laboratorium i februar 2008 og bruges som et avanceret tr\u00e6ningsredskab til astronauter. Den vil p\u00e5 sigt blive tilg\u00e6ngelig for patienter i genoptr\u00e6ning og til tr\u00e6ning af atleter.<\/p>","protected":false},"excerpt":{"rendered":"
