Jos et pid\u00e4 liikunnasta, el\u00e4m\u00e4 avaruusasemalla ei ole sinua varten! Jokainen Kansainv\u00e4lisen avaruusaseman (ISS) miehist\u00f6n j\u00e4sen viett\u00e4\u00e4 jopa kaksi tuntia p\u00e4iv\u00e4ss\u00e4 erilaisilla kuntoilulaitteilla. Kaikki t\u00e4m\u00e4 vaivann\u00e4k\u00f6 on v\u00e4ltt\u00e4m\u00e4t\u00f6nt\u00e4, jotta voidaan torjua pitkill\u00e4 avaruuslennoilla tapahtuvaa fyysisen kunnon heikkenemist\u00e4. Se my\u00f6s helpottaa astronauttien sopeutumista normaaliin painovoimaan, kun he palaavat Maahan.<\/p>\n<\/div>\n

Luut, syd\u00e4n ja keuhkot, lihakset ja elimet muuttuvat painottomuudessa. Muutoksiin kuuluvat muun muassa luiden kalsiumin menetys sek\u00e4 syd\u00e4men heikkeneminen, sill\u00e4 sen ei en\u00e4\u00e4 tarvitse ty\u00f6skennell\u00e4 painovoimaa vastaan pumppaamaan verta kehon eri osiin. Mit\u00e4 pidemp\u00e4\u00e4n astronautti viipyy avaruudessa, sit\u00e4 selvemmin muutokset tulevat esiin.<\/p>\n

Maassa olevat l\u00e4\u00e4k\u00e4rit seuraavat miehist\u00f6n kuntoa ja arvioivat, kuinka paljon heid\u00e4n kuntonsa on muuttunut. He voivat tarvittaessa ohjeistaa miehist\u00f6\u00e4 muuttamaan harjoitusohjelmiaan. ISS:n aluksella on useita kuntoilulaitteita, joita astronautit k\u00e4ytt\u00e4v\u00e4t. Niihin kuuluu kaksi juoksumattoa, vastuslaite ja kuntopy\u00f6r\u00e4 (ergometri). Kaikissa laitteissa astronauttien on oltava kiinnitettyin\u00e4 laitteeseen, jotta he eiv\u00e4t leijailisi pois!<\/p>\n

Juoksumattoja k\u00e4ytet\u00e4\u00e4n k\u00e4velyn ja juoksun simuloimiseen normaalissa painovoimassa. Py\u00f6r\u00e4\u00e4 voidaan k\u00e4ytt\u00e4\u00e4 k\u00e4sien tai jalkojen harjoittamiseen. Vastusharjoituslaite muistuttaa melko paljon painonnostoa Maassa. Sen avulla k\u00e4ytt\u00e4j\u00e4 voi suorittaa sarjan fyysisi\u00e4 harjoituksia ollessaan kiinnitettyn\u00e4 joustaviin bungee-k\u00f6ysiin. Kannettava tietokone seuraa sykett\u00e4 ja muita elintoimintoja, kun astronautit k\u00e4ytt\u00e4v\u00e4t laitteita.<\/p>","protected":false},"excerpt":{"rendered":"
