Tal como se observa en el microscopio, el centro del hueso aparece carcomido. Esto conduce a un gran incremento de fracturas de cadera, mu\u00f1ecas o columna vertebral. Este problema est\u00e1 provocado en gran medida por la enfermedad y la falta de ejercicio.<\/p>\n<\/div>\n<p>La ingravidez del espacio provoca un problema parecido, ya que hasta los astronautas m\u00e1s j\u00f3venes y mejor preparados sufren p\u00e9rdida de masa \u00f3sea en alguna medida.<\/p>\n<p>La investigaci\u00f3n espacial est\u00e1 ayudando a los cient\u00edficos a comprender lo que sucede y a encontrar una manera de combatir dicho problema.<\/p>\n<p>Uno de los m\u00e9todos consiste en recurrir a voluntarios que permanecen en cama durante varias semanas. En esos estudios se comprueba la transformaci\u00f3n del hueso cuando no debe soportar ning\u00fan peso.<\/p>\n<p>La ESA tambi\u00e9n desarrolla nuevos aparatos para ejercicio y equipos m\u00e9dicos para su utilizaci\u00f3n en la Tierra y el espacio.<\/p>\n<p>Uno de los dispositivos probados en los vuelos de microgravedad de la ESA es una m\u00e1quina para colocar y retirar el pie.
