Así puedes prevenir el deterioro de los músculos por la edad

De acuerdo con una investigación internacional de la Universitat Pompeu Fabra y del Institut de Recerca Biomédica, en Barcelona, el mantener un horario regular en las comidas, con periodos de ayuno prolongado, regula el ritmo circadiano de las células musculares, lo que previene el deterioro de los músculos por la edad y ayude a retrasar el envejecimiento de todo el organismo.

La investigación inició hace ocho años con el fin de entender cómo regulan sus ritmos circadianos los organismos y tejidos, ya que estudios anteriores revelaron que el reloj central del cuerpo humano está en el núcleo supraquiasmático del cerebro.

Si la señal al reloj central se deteriora, como normalmente ocurre con las personas mayores, los relojes periféricos pueden compensar el deterioro y restaurar un ritmo circadiano adecuado. Mientras que en experimentos con ratones, cuyo reloj central está lesionado, si se regulan las horas, esto es suficiente para que las células musculares recuperen un ritmo adecuado.

Otro hábito que ayuda a mantener un ritmo circadiano saludable es el de exponerse a la luz solar de día, evitar luces de longitudes de onda corta durante las noches, tener una buena higiene del sueño y hacer ejercicio.

Si se regula de manera inadecuada los relojes biológicos, esto conduce a un envejecimiento prematuro, algo ya comprobado por investigaciones científicas, y esto afecta en los músculos, apareciendo el deterioro de la musculatura con la edad, ya que se altera la producción adecuada de proteínas.

“Las células deben oscilar entre periodos de actividad y de inactividad. Si nos exponemos a luz azul y comemos cuando ya es de noche, interpretan que todavía es de día y funcionan peor. Personalmente como cada día a la misma hora, a la una, y en casa cenamos a las ocho, no más tarde”.

Los investigadores también estudiaron la relación entre el reloj periférico de la piel y el central del cerebro, donde la piel modula la señal horaria que recibe del cerebro mediante estímulos externos.

“Los músculos representan el 50% del volumen y del peso del cuerpo, y segregan una gran cantidad de proteínas que tienen efectos en otros tejidos. Es posible que, si se mejora el funcionamiento de los músculos, mejoren también otros órganos”.
