Om du inte gillar att tr\u00e4na \u00e4r livet p\u00e5 en rymdstation inget f\u00f6r dig! Varje bes\u00e4ttningsmedlem p\u00e5 den internationella rymdstationen (ISS) tillbringar upp till tv\u00e5 timmar om dagen p\u00e5 olika tr\u00e4ningsmaskiner. All denna anstr\u00e4ngning \u00e4r n\u00f6dv\u00e4ndig f\u00f6r att motverka den fysiska f\u00f6rs\u00e4mring som uppst\u00e5r under l\u00e5nga rymdf\u00e4rder. Det g\u00f6r det ocks\u00e5 l\u00e4ttare f\u00f6r astronauterna att \u00e5teranpassa sig till normal tyngdkraft n\u00e4r de \u00e5terv\u00e4nder till jorden.<\/p>\n<\/div>\n

Ben, hj\u00e4rta och lungor, muskler och organ f\u00f6r\u00e4ndras alla i tyngdl\u00f6shet. F\u00f6r\u00e4ndringarna omfattar bland annat kalciumf\u00f6rlust fr\u00e5n benen och en f\u00f6rsvagning av hj\u00e4rtat, som inte l\u00e4ngre beh\u00f6ver arbeta mot tyngdkraften f\u00f6r att pumpa blod runt i kroppen. Ju l\u00e4ngre en astronaut vistas i rymden, desto tydligare blir de f\u00f6r\u00e4ndringar som sker.<\/p>\n

L\u00e4karna p\u00e5 jorden \u00f6vervakar bes\u00e4ttningens kondition och utv\u00e4rderar hur deras kondition har f\u00f6r\u00e4ndrats. De kan vid behov uppmana bes\u00e4ttningen att anpassa sina tr\u00e4ningsprogram. Ombord p\u00e5 ISS finns flera tr\u00e4ningsmaskiner som anv\u00e4nds av astronauterna. Bland annat tv\u00e5 l\u00f6pband, en motst\u00e5ndstr\u00e4ningsmaskin och en cykelmaskin (ergometer). I samtliga fall m\u00e5ste astronauterna f\u00e4stas vid maskinen s\u00e5 att de inte flyter iv\u00e4g!<\/p>\n

L\u00f6pbanden anv\u00e4nds f\u00f6r att simulera g\u00e5ng och l\u00f6pning under normal tyngdkraft. Cykelmaskinen kan anv\u00e4ndas f\u00f6r att tr\u00e4na armar eller ben. Motst\u00e5ndstr\u00e4ningsmaskinen liknar i stort sett styrketr\u00e4ning p\u00e5 jorden. Den g\u00f6r det m\u00f6jligt f\u00f6r anv\u00e4ndaren att utf\u00f6ra en serie fysiska \u00f6vningar medan hen h\u00e5lls fast av elastiska bungeesn\u00f6ren. En b\u00e4rbar dator \u00f6vervakar hj\u00e4rtfrekvensen och andra vitala parametrar medan astronauterna anv\u00e4nder maskinerna.<\/p>","protected":false},"excerpt":{"rendered":"
