Este enfoque no es nuevo para ellos, ya que en 2022 intentaron una formulaci\u00f3n similar que no dio los resultados esperados.<\/p>\n<h3>Un experimento inicial que no prosper\u00f3<\/h3>\n<p>En 2022, el equipo trabaj\u00f3 con una bebida que combinaba polilactato y carbohidratos. Sin embargo, la baja concentraci\u00f3n de lactato y el sabor desagradable llevaron a que los ciclistas rechazaran su uso. Por esto, el proyecto fue archivado en favor de estrategias m\u00e1s convencionales.<\/p>\n<p>Cuatro a\u00f1os m\u00e1s tarde, el lactato ex\u00f3geno reapareci\u00f3, esta vez con una formulaci\u00f3n desarrollada junto a <strong>Enervit<\/strong>. La bebida conten\u00eda 90 gramos de carbohidratos y 10 gramos de lactato s\u00f3dico, destinada a etapas espec\u00edficas del Tour.<\/p>\n<h3>Expectativas y desaf\u00edos cient\u00edficos<\/h3>\n<p>A pesar del inter\u00e9s que ha generado, la evidencia cient\u00edfica sobre los beneficios del lactato ex\u00f3geno sigue siendo escasa. Desde los a\u00f1os noventa, teor\u00edas como el \u00ab<strong>Lactate Shuttle<\/strong>\u00bb han sugerido su potencial como fuente de energ\u00eda, pero los estudios a\u00fan no demuestran mejoras consistentes en el rendimiento.<\/p>\n<p>Algunas investigaciones recientes sugieren que el lactato podr\u00eda ayudar a combatir la fatiga central, pero se necesitan m\u00e1s estudios para confirmar su eficacia en situaciones de competici\u00f3n real. Por ahora, el lactato ex\u00f3geno sigue siendo un prometedor pero incierto campo de investigaci\u00f3n en la nutrici\u00f3n deportiva.<\/p>\n<hr>\n<p><em>Con informaci\u00f3n de <a href=\"https:\/\/www.brujulabike.com\/uae-fracaso-lactato-exogeno-tour-francia-ciencia\/\" target=\"_blank\" rel=\"nofollow noopener\">Br\u00fajula Bike<\/a>.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>El UAE Team Emirates-XRG prob\u00f3 el lactato ex\u00f3geno en el Tour de Francia 2026, pero la evidencia cient\u00edfica a\u00fan es limitada.<\/p>\n","protected":false},"author":1,"featured_media":1911,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[21],"tags":[],"class_list":["post-1912","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-dietetica"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.4 -
