A 60 \u00e9v feletti n\u0151k 50%-je szenved csontritkul\u00e1sban. Mikroszk\u00f3p alatt megfigyelhet\u0151, hogy a csont k\u00f6zepe mintha el lenne r\u00e1gva. Ez a cs\u00edp\u0151-, csukl\u00f3- vagy gerinct\u00f6r\u00e9sek sz\u00e1m\u00e1nak jelent\u0151s emelked\u00e9s\u00e9hez vezet. A probl\u00e9ma els\u0151sorban betegs\u00e9gek \u00e9s a testmozg\u00e1s hi\u00e1nya miatt alakul ki.<\/p>\n<\/div>\n

Hasonl\u00f3 probl\u00e9ma jelentkezik az \u0171r s\u00falytalans\u00e1g\u00e1ban is, amikor m\u00e9g a legfiatalabb \u00e9s legfittebb \u0171rhaj\u00f3sokn\u00e1l is csonts\u0171r\u0171s\u00e9g-cs\u00f6kken\u00e9s tapasztalhat\u00f3.<\/p>\n

Az \u0171rkutat\u00e1s seg\u00edt a tud\u00f3soknak meg\u00e9rteni a jelens\u00e9get, \u00e9s megold\u00e1st tal\u00e1lni a probl\u00e9ma lek\u00fczd\u00e9s\u00e9re.<\/p>\n

Az egyik m\u00f3dszer az, hogy olyan \u00f6nk\u00e9nteseket vonnak be a vizsg\u00e1latba, akik hetekig \u00e1gyban fekszenek. Ezek az \u00e1gynyugalomra \u00e9p\u00fcl\u0151 vizsg\u00e1latok azt mutatj\u00e1k meg, hogyan v\u00e1ltoznak a csontok, ha nem nehezedik r\u00e1juk terhel\u00e9s.<\/p>\n

Az ESA emellett \u00faj edz\u0151g\u00e9peket \u00e9s orvosi berendez\u00e9seket is fejleszt, amelyeket a F\u00f6ld\u00f6n \u00e9s az \u0171rben egyar\u00e1nt haszn\u00e1lni lehet.<\/p>\n

Az ESA mikrogravit\u00e1ci\u00f3s rep\u00fcl\u00e9sein tesztelt eszk\u00f6z\u00f6k egyike egy fel- \u00e9s lesz\u00e1ll\u00e1sra szolg\u00e1l\u00f3 g\u00e9p. Egy m\u00e1sik pedig a norm\u00e1l j\u00e1r\u00e1st \u00e9s fut\u00e1st ut\u00e1nozza, mik\u00f6zben a rezg\u00e9sek csontokra gyakorolt hat\u00e1s\u00e1t vizsg\u00e1lja.<\/p>","protected":false},"excerpt":{"rendered":"
