Teens who were breastfed at birth have stronger leg muscles

A new study appears to have found yet another amazing benefit of breastfeeding – it improves the physical condition of future adolescents.

It showed that adolescents who are breast fed at birth have stronger leg muscles than those who received artificial milk. Moreover, muscular leg strength was greater in those who had been breastfed for a longer period of time.

Enrique Garcia Artero, lead author of the study and a researcher at the University of Granada, wanted to find out whether adolescents benefited from having been breastfed as newborns.

His team especially wanted to know whether there was a relationship between the duration of breastfeeding babies and their physical condition in adolescence.

The researchers interviewed the parents of 2,567 adolescents about the type of feeding their children received at birth and the time this lasted.

They also tested the adolescents to evaluate several abilities such as aerobic capacities and their muscular strength.

They found that the kids who had been breastfed as infants had stronger legs than the kids who were not. Also, those who had breastfed longer had greater muscle strength than those who weaned earlier.

Even those who were nursed well performed better at horizontal jumping tasks, regardless of fat mass, muscle mass or height. Those who had been breastfeed at least three months failed half as much in the jumping tests as those who had not been breastfed at all.

«Until now, no studies have examined the association between breastfeeding and future muscular aptitude,» said Artero.

«However, our results concur with the observations made as regards other neonatal factors, such as weight at birth, are positively related to better muscular condition during adolescence,» he added.

The study is published in the latest issue of the Journal of Nutrition.

Breastfeeding Leads to Stronger Legs in Adolescence

The benefits of breastfeeding are endless and a recent study has further shown the positives of breastfeeding. It has been found that apart from being helpful in so many other things, mother’s milk also plays a vital role in improving the physical health of a child in adolescence.

It was reported that leg muscles of children who were fed during their nascent years of life were much stronger, when compared to children who received artificial milk. Apart from that, the strength grew with the passage of time for which, the child had been fed by the mother.

Talking about the study, Lead Author Enrique Garcia Artero from the University of Granada said that the basic intent of the study was to find out whether breastfeeding actually benefitted newborns in the long-term.

The study involved an interview of 2,567 adolescents and their parents, who were questioned about the type of feed they received and the duration. The adolescents were also assessed on their overall strengths.

Following the evaluation scientists reached the above conclusion. Though, it was also found that children who were provided a good feed also performed well in tasks related to jumping. Artero also informed that there had been no such studies previously, which had looked into these intricacies of breastfeeding.

El bilingüismo mejora la atención y la memoria

El proyecto Procesos de Atención y memoria en la selección de idiomas en bilingües y traductores, coordinado por los profesores Teresa Bajo Molina y Pedro Macizo Soria, de la Universidad de Granada, ha demostrado que el bilingüismo es beneficioso porque “mejora las capacidades atencionales y entrena la memoria”, explica la profesora Bajo. Es decir, que saber dos idiomas tiene ventajas más allá de la evidente facilidad para comunicarse.

La profesora Teresa Bajo Molina y su equipo han llegado a esta conclusión a través de una serie de experimentos realizados con personas bilingües en español y en inglés, “entendiendo por bilingüismo el conocimiento alto de dos idiomas y su uso frecuente; es decir, no es necesario haber crecido con las dos lenguas a la vez”, aclara la investigadora.

Diferentes grupos de bilingües, de entre 16 y 24 personas, han participado en los experimentos y han realizado una serie de pruebas (p.e. nombrar dibujos en diferentes idiomas, leer o traducir frases, etc.) en que se mide el tiempo de respuesta y la actividad eléctrica cerebral. Así, sus resultados muestran que una persona bilingüe activa los dos idiomas a la vez incluso en situaciones en que necesita sólo uno.

Esta activación, unas veces supone una ventaja y otras una dificultad. Por ejemplo, “presentamos un dibujo a la persona para que lo nombre. En el caso de las palabras cognadas (palabras que se parecen mucho en los dos idiomas y representan lo mismo), como “piano”, se activan los dos idiomas y la identificación del dibujo es mucho más rápida que para un monolingüe. Facilita el hecho de que haya características comunes entre las dos representaciones léxicas”. Sin embargo, para palabras homógrafas (que se escriben igual pero no significan lo mismo), como “pie” (en inglés, pastel), se activan los dos conceptos a la vez creando interferencias y la persona tiene que seleccionar, con lo que el tiempo de respuesta es mayor”, explica la profesora Bajo.

El cerebro de adapta al idioma

Para resolver el conflicto entre los dos idiomas que se activan y que la persona pueda seleccionar el que es apropiado, es necesaria la actuación de un mecanismo atencional que implica la parte prefrontal del cerebro y que inhibe aquel término que en el contexto no es apropiado demostrando que se puede ignorar información interna.

En este punto, el grupo de investigación de la profesora Bajo introduce el análisis de los traductores simultáneos. “En el caso de un intérprete no se puede inhibir uno de los dos idiomas sino que los tiene que mantener activos al mismo tiempo porque escucha en uno y habla en otro. Los traductores consiguen mantenerlos activos a pesar de que supone mucho esfuerzo cognitivo. Esto significa que el cerebro puede actuar de forma diferente a como lo haría de forma natural dependiendo de la práctica a la que se ve expuesto, es decir, el cerebro se adapta, es plástico”, asegura Teresa Bajo. “Un intérprete también usa el mecanismo de memoria de trabajo (la que te permite mantener activa información para realizar una tarea) de forma más eficaz”.

“Tras todas estas pruebas, hemos demostrado que el cerebro puede responder de forma diferente con entrenamiento” y el aprendizaje de otro idioma es, de algún modo, un entrenamiento. En general, “ser bilingüe tiene más ventajas que inconvenientes. Aunque aquel que maneja dos idiomas, los maneja un poco más lentamente que otro que sólo usa uno, las consecuencias generales de ser bilingüe son que usa mecanismos atencionales mucho más que los que no lo son; los bilingües son capaces de manejar mejor situaciones de selección, de toma de decisiones. En situaciones de distracción se concentran más fácilmente para elegir”, explica. De hecho, otros estudios hechos en Canadá con mayores, apunta Bajo, “han demostrado que el uso de otro idioma retrasa el deterioro de la edad”.

Los niveles altos de bilingüismo aumentan la concentración

Como explica la profesora Bajo Molina, “ahora estamos afinando la investigación por grados de bilingüismo. A falta de corroborar los resultados, estamos encontrando que si hay idioma muy dominante, interfiere mucho, y es el mecanismo de inhibición el que funciona mucho más. Mientras que en los niveles más altos de bilingüismo, los idiomas no compiten y dominan los procesos de focalización, lo que les hace mejores en las tareas que obligan a mantener la atención, la concentración”.

El siguiente reto de este grupo investigador es “estudiar el desarrollo de niños que están en colegios bilingües y ver el desarrollo de los procesos atencionales a medida que aumenta el conocimiento del segundo idioma. Además queremos comparar a menores que tienen alguna dificultad en el lenguaje (problemas de lenguaje, problemas atencionales, etc….) con los que no lo tienen. Queremos saber si, en este caso, las ventajas superan a los inconvenientes como es en el caso general”, concluye Teresa Bajo.

El enigma eterno de Tutmosis III

Como casi siempre que se excava en el pasado, al pasar el pincel sobre la historia la piedra desvela intrigas, traiciones, luchas de poder y, de vez en cuando, un personaje de cualidades asombrosas que nos hacen soñar al estilo de las películas en tecnicolor. Tutmosis III, soberano de la XVIII dinastía que reinó en el siglo V a.C., es uno de esos héroes casi cinematográficos que la antigua civilización faraónica atesora en sus anales.

Para saber más de este faraón que llevó a Egipto a convertirse en la principal potencia de Oriente Próximo, desde hace tres años la arqueóloga y doctora en Historia Myriam Seco (Sevilla, 1967), dedica sus esfuerzos a desenterrar su templo funerario en Luxor. El equipo que dirige realiza en la antigua Tebas un trabajo que otros dejaron inacabado en tres campañas cortas y poco fructíferas: en 1886, 1906 y en los años 30. Entonces se describió a Tutmosis III como el Napoleón egipcio. Un estratega y militar imbatido que llevó al país del Nilo a ampliar sus fronteras y dominar las principales rutas comerciales de Oriente. Pero a pesar de la relevancia de su constructor, el templo cayó en el olvido y permaneció abandonado y cubierto de escombros hasta 2008.

«Cuando en el siglo XIX se empezaron a explorar los restos faraónicos, la mayor parte de los estudiosos se interesaron por aquellas construcciones que estaban mejor conservadas, así que olvidaron este lugar», lamenta Myriam Seco. Esta edificación de Tutmosis III es el único templo funerario de los que están en el Valle de los Reyes que está construido en distintas terrazas o niveles, al igual que el de Deir El Bahari, levantado por su tía y madrastra, la legendaria reina Hatshepsut. «Hemos descubierto que se construyó sobre una antigua necrópolis y que hay cuatro niveles de tumbas bajo él», afirma orgullosa. «También hemos despejado la rampa principal y el pilono de acceso. Uno de los pocos que se conservan de esta época, ya que al ser de adobe y no de piedra han sufrido más el paso del tiempo», destaca.

La excavación, en la que trabaja un equipo multidisciplinar de arqueólogos, topógrafos, restauradores, antropólogos y obreros, recibe además a alumnos de Arqueología y Bellas Artes de la Universidad de Granada que hacen sus prácticas en el yacimiento, participando en las diferentes etapas, bien a pie de zanja, bien documentando los hallazgos. Seco destaca además que, por primera vez, se esté llevando a cabo una colaboración entre España y Egipto, para dar formación a los inspectores del Servicio de Antigüedades del país.

La doctora cuenta que labores similares han requerido entre 20 y 30 años para darse por finalizados, pero no le preocupa. Momentos como el que vivió hace unas semanas al descubrir intacta una tumba compensan «con creces» los esfuerzos realizados. «La emoción de abrir una cámara sellada y ver a quien ha pertenecido es uno de los momentos más especiales que he vivido», afirma la arqueóloga.

Tutmosis III logró que Egipto dominara más de 100 estados e importantes rutas comerciales, hasta incluir en sus fronteras Nubia, Libia, la costa fenicia, Siria y Chipre. Su política de conquista no destacó por su crueldad o su encarnizamiento con el enemigo, como subraya el doctor Zahi Hawass, secretario general del Consejo Superior de Antigüedades egipcio, sino por su inteligencia y su pragmatismo político. «Solía capturar a los príncipes de los países que conquistaba y los traía a Egipto para que conocieran su cultura y aprendieran que debían ser leales a ese gran imperio», apunta el egiptólogo.

Myriam Seco pone en valor su colosal tarea: «Lo que estamos haciendo es recuperar un legado valiosísimo que nos permitirá desvelar los secretos de uno de los faraones más importantes de Egipto».

Mother’s Milk Improves Physical Condition of Future Adolescents, Study Finds

Breast feeding new born babies has lots of advantages in the short and in the long-term for babies. A study has confirmed the recently discovered benefits, which had not been researched until now. Adolescents who are breast fed at birth have stronger leg muscles than those who received artificial milk.

Enrique García Artero, the principal author of the study and researcher at the University of Granada pointed out that, «Our objective was to analyse the relationship between the duration of breastfeeding babies and their physical condition in adolescence.» «The results suggest further beneficial effects and provide support to breast feeding as superior to any other type of feeding.»

The authors asked the parents of 2,567 adolescents about the type of feeding their children received at birth and the time this lasted. The adolescents also carried out physical tests in order to evaluate several abilities such as aerobic capacities and their muscular strength.

The paper, which was published in the Journal of Nutrition, shows that the adolescents who were breastfed as babies ha stronger leg muscles than those who were not breastfed. Moreover, muscular leg strength was greater in those who had been breastfed for a longer period of time.

This type of feeding (exclusively or in combination with other types of food) is associated with a better performance in horizontal jumping by boys and girls regardless of morphological factors such as fat mass, height of the adolescent or the amount of muscle.

Adolescents who were breastfed from three to five months, or for more than six months had half the risk of low performance in the jump exercise when compared with those who had never been breastfed.

García Artero stressed that, «Until now, no studies have examined the association between breastfeeding and future muscular aptitude.» «However, our results concur with the observations made as regards other neonatal factors, such as weight at birth, are positively related to better muscular condition during adolescence.»

What importance does breastfeeding have?

«If all children were exclusively breastfed from birth, it would be possible to save approximately 1.5 million lives.» This was stated by the UNICEF, which pointed out that breast feeding is the «perfect feed» exclusively during the first six months of life and additionally over two years.

As regards the new born, the advantages in the first years of life include immunological protection against allergies, skin diseases, obesity and diabetes, as well as a guarantee of the growth, development and intelligence of the baby.

The benefits also substantially involve the woman: reduction of post-birth haemorrhage, anaemia, maternity mortality, and the risk of breast and ovarian cancer, and it strengthens the affective link between mother and child. «Let’s forget about the money saved by not buying other types of milk and baby bottles,» says García Artero.

Benefits of breastfeeding last into adolescence

Breastfeeding appears to confer advantages well beyond infancy, with European researchers reporting significant differences in muscle strength and aerobic capacity when comparing teenagers who were breastfed as infants with others who were not breastfed.
