On peut estimer qu\u2019un individu de 70kg avec 10% de graisses corporelles poss\u00e8de 68 250kcal d\u2019\u00e9nergie disponible avec les acides gras endog\u00e8nes.<\/p>\n\n\n\n
Le glycog\u00e8ne est le carburant le plus important lors d\u2019un exercice d\u2019endurance. Mais lorsque les r\u00e9serves s\u2019\u00e9puisent la fatigue augmente.<\/p>\n\n\n\n
M\u00eame un apport \u00e9lev\u00e9 en glucides exog\u00e8nes (90-120g\/ h) ne permet pas de satisfaire les besoins \u00e9nerg\u00e9tiques lors d\u2019un triathlon IronMan.<\/p>\n\n\n\n
Il faut apprendre \u00e0 l\u2019organisme \u00e0 mieux utiliser les graisses endog\u00e8nes durant l\u2019effort en am\u00e9liorant la flexibilit\u00e9 m\u00e9tabolique.<\/p>\n\n\n\n
L\u2019entra\u00eenement IM doit s\u2019axer sur la r\u00e9duction de l\u2019utilisation des glucides \u00e0 l\u2019intensit\u00e9 cible IM afin de retarder l\u2019apparition de la fatigue li\u00e9e \u00e0 l\u2019\u00e9puisement du glycog\u00e8ne. Si l\u2019athl\u00e8te utilise largement l’oxydation des graisses pour soutenir le m\u00e9tabolisme pendant un exercice prolong\u00e9 \u00e0 son intensit\u00e9 comp\u00e9titive, cela devrait r\u00e9duire le besoin d’oxydation endog\u00e8ne des glucides, et donc l’\u00e9puisement du glycog\u00e8ne musculaire li\u00e9 \u00e0 la fatigue\u00a0\u00bb<\/p>\n\n\n\n
