Le corps humain subit de nombreuses modifications lors des missions spatiales de longue dur\u00e9e, parmi lesquelles une perte musculaire et osseuse graduelle, le mal de l'espace et des alt\u00e9rations cardiaques et pulmonaires.<\/p>\n<\/div>\n

Such changes can affect astronauts’ well-being and efficiency, both in orbit and after their return to Earth.<\/p>\n

De nombreuses \u00e9tudes ont \u00e9t\u00e9 men\u00e9es pour en savoir plus sur les effets graduels de l'impesanteur. L'une des m\u00e9thodes les plus faciles et \u00e9conomiques pour \u00e9tudier ces effets est l'alitement.<\/p>\n

De nombreuses \u00e9tudes de ce type ont \u00e9t\u00e9 r\u00e9alis\u00e9es au cours de ces 40 derni\u00e8res ann\u00e9es. Elles ont permis de recueillir d'importantes informations sur le comportement de l'organisme humain pendant de longues p\u00e9riodes d'inactivit\u00e9.<\/p>\n

Des volontaires restent alit\u00e9s pendant des semaines, souvent en position inclin\u00e9e, t\u00eate vers le bas. Dans ces conditions, avec une utilisation tr\u00e8s r\u00e9duite du squelette et des muscles, le comportement du corps est similaire \u00e0 celui qui aurait lieu dans l'espace.<\/p>\n

Les chercheurs se servent de ces \u00e9tudes pour tester de nouveaux m\u00e9dicaments et d'autres m\u00e9thodes permettant de lutter contre les effets de l'impesanteur. De nombreux instruments et traitements ainsi d\u00e9couverts trouvent aujourd'hui des applications cliniques et viennent en aide \u00e0 de nombreux patients.<\/p>\n

La recherche future sur la Station spatiale internationale devrait permettre de nouveaux progr\u00e8s pour la sant\u00e9. Cette recherche ouvrira peut-\u00eatre la voie aux voyages humains au-del\u00e0 de l'orbite terrestre et \u00e0 l'exploration de mondes nouveaux.<\/p>","protected":false},"excerpt":{"rendered":"
