New marks in high competition sports.


The world sport of high sport competition confronts since several years great challenges : to break certain world records (to run 100 m below 8,5 seconds, for example). In front of it, some elite sportsmen ingest forbidden (stimulants/invigorating) substances, vetoed by international federations. For us the impasse will be demolished by approaches but realists: allowing the employment of certain stimulants or, opening the way to innovations. For elite sportsmen with millionaire contracts of for half, the sky is the limit and the ethics something that you can obviate. Hence he/she interests to comment the possible employment in the following 3-5 years, of stem cells coming from umbilical cord to repair sport injuries and to impede the abrupt ceasings of sport successful careers. That’s the reason of a expansion of banks of stem cells for possible cures and rehabilitations of tendons, ligaments, muscles, cartilages, construction of muscles and increment of physical capacities in elite athletes, not acquirable for conventional methods.



According to Dr. Scott Rodeo, orthopedist of Manhattan's Hospital for Special Surgery, the technique has been successful in the reconstruction of the anterior ligament cruciato and the cuff rotator of the shoulder, in rats. Now it is attempted fat and muscle biopsies in childrens from among 5-6 years, to freeze them and to preserve their stem cells, said Dr. Johnny Huard, director of Stem Cell Research Center of the Children's Hospital of Pittsburgh."At the moment alone stem cells of adult people would be used, children's taken stem cells when being born or, coming from a national bank of derived stem cells of placenta or umbilical cord". That would exist of course a section dedicated to donors with athletic exceptional aptitudes, says Dr. Robert Hariri, founder of Lifebank, one of the 25 private banks of USA. Some objections like those of the Dr. Freddie Fu, orthopedist of University of Pittsburgh Medical Center, argues that there are side effects to value, even. For their side the Dr. J. Huard, adds that it will be difficult that the officials of the tournaments can discover improvements coming from the own human body.


Nuevas marcas en deportes de élite.

El deporte mundial de alta competencia confronta desde hace varios años retos insalvables: batir marcas mundiales/limite (correr 100 m planos por debajo de los 8,5 segundos, por ejemplo). Frente a ello, algunos deportistas de élite ingieren sustancias prohibidas (estimulantes/vigorizantes), vetadas por federaciones internacionales. Para nosotros el impasse sera derribado por criterios mas realistas : o, se permite el empleo de ciertos estimulantes o, se da paso a innovaciones. Para deportistas de élite con contratos millonarios de por medio, el cielo es el limite y la ética algo que se puede obviar. Por ello interesa comentar el posible empleo en los siguientes 3-5 años, de celulas madre procedentes de cordó umbilical para reparar injurias deportivas e impedir ceses bruscos de exitosas carreras deportivas. Lo que está conllevando a una expansion de bancos de céulas madre para posibles curaciones y rehabilitaciones de tendones, ligamentos, musculos, cartílagos, construcción de músculos e incremento de capacidades fisicas en atletas de élite, no adquiribles por métodos convencionales.


Según el Dr. Scott Rodeo, ortopedista del Manhattan’s Hospital for Special Surgery, la técnica ha sido exitosa en la reconstrucción del ligamento cruciato anterior y el manguito rotador del hombro, en ratas. Ahora se intenta biopsiar grasa o músculo de niños de entre 5-6 años, helarlos y conservar sus células madre, dice el Dr. Johnny Huard, director del Stem Cell Research Center of the Children’s Hospital of Pittsburgh”. De momento solo se emplearian células madres de personas adultas, celulas tomadas de niños al nacer o, procedentes de un banco nacional de celulas madre derivadas de placenta o cordón umbilical. Existiria eso si, una sección dedicada a donantes con aptitudes atléticas excepcionales, dice el Dr. Robert Hariri, fundador del Lifebank, uno de los 25 bancos privados de USA. Algunas objeciones como las del Dr. Freddie Fu, ortopedista del University of Pittsburgh Medical Center, arguyen que “hay muchos efectos colaterales por valorar, aún''. Por su lado el Dr. J. Huard, agrega que "será difícil que los oficiales de los torneos puedan descubrir mejoras proveniente del propio cuerpo humano“.
