Un art\u00edculo que acaba de publicarse en la revista \u00abNature Genetics\u00bb:http:\/\/dx.doi.org\/10.1038\/ng2122 relaciona una mayor capacidad de resistencia muscular al esfuerzo con una mutaci\u00f3n gen\u00e9tica (en el gen [\u00abACTN3\u00bb:http:\/\/www.genecards.org\/cgi-bin\/carddisp.pl?gene=ACTN3], alfa actinina 3). Esta mutaci\u00f3n cambiar\u00eda el metabolismo de algunas fibras musculares, haciendo que pasaran del tipo r\u00e1pido al tipo lento (&#167;). Esta mutaci\u00f3n var\u00eda en las diferentes poblaciones humanas, de un 10% en africanos a un 50% en asi\u00e1ticos o europeos.<br \/>\nSi esto se confirma, veo en mi bola de cristal una nueva generaci\u00f3n de corredores de marat\u00f3n\/velocistas especialmente elegidos por la presencia\/ausencia de la mutaci\u00f3n.
