\"epoc\"<\/figure>\n\n\n\n

Si vous utilisez une Suunto<\/a> Ambit ou d’autres mod\u00e8les plus ancien comme le T6, alors vous avez peut \u00eatre remarqu\u00e9 que sur les graphiques il y avait une des variables qui se nommait EPOC (en anglais excess post-exercice oxygen consumtion). Cette variable tr\u00e8s scientifique permet de donner une estimation de votre temps de r\u00e9cup\u00e9ration.<\/p>\n\n\n\n

L’id\u00e9e est que pendant un effort vous consommez plus d’oxyg\u00e8ne que vous en auriez consomm\u00e9 lors d’une activit\u00e9 normale. Plus l’exercice est long, plus il est intense, plus vous avez consomm\u00e9 d’oxyg\u00e8ne et indirectement plus vous allez mettre de temps \u00e0 r\u00e9cup\u00e9rer.<\/p>\n\n\n\n

Ce type de mesure est en g\u00e9n\u00e9ral effectu\u00e9 en laboratoire sur un tapis de course en expirant et inspirant avec un masque sur la bouche pour voir la consommation d’oxyg\u00e8ne.<\/p>\n\n\n\n

Des chercheurs ont r\u00e9ussi \u00e0 mod\u00e9liser la relation entre la fr\u00e9quence cardiaque et la consommation d’oxyg\u00e8ne. Le mod\u00e8le exact dit que l’EPOC est calcul\u00e9 \u00e0 partir de l’intensit\u00e9 de l’entrainement<\/a> sur un temps d\u00e9fini et de l’EPOC \u00e0 l’instant d’avant. On retrouve la r\u00e8gle empirique, plus l’effort est long et intense, plus il est long de r\u00e9cup\u00e9rer.<\/p>\n\n\n\n

D’apr\u00e8s mes constatations, si lors d’un entrainement je m\u2019arr\u00eate  et je marche tranquillement l’EPOC va redescendre progressivement mais sur un exercice de type fractionn\u00e9, comme le coeur ne descend pas beaucoup entre les s\u00e9quences rapides la courbe d’EPOC continue de monter. Cependant dans les exemples fournis par la soci\u00e9t\u00e9 FirstBeat Technologies, les athl\u00e8tes pris en exemple ont une EPOC qui diminue l\u00e9g\u00e8rement sur une s\u00e9ance d’interval training… je dois faire partie des athl\u00e8tes pas suffisamment entrain\u00e9s pour v\u00e9rifier ce ph\u00e9nom\u00e8ne.<\/p>\n\n\n\n

En dessous d’un certain seuil de fr\u00e9quence cardiaque, l’EPOC diminue vous \u00eates donc dans une phase de r\u00e9cup\u00e9ration. Au final, cette valeur va permettre de d\u00e9terminer votre temps de r\u00e9cup\u00e9ration minimum qui est en fait le temps n\u00e9cessaire pour que l’EPOC reviennent \u00e0 z\u00e9ro.<\/p>\n\n\n\n

Cela n’enl\u00e8ve rien \u00e0 vos sensations pour savoir si vous avez r\u00e9cup\u00e9r\u00e9 ou pas mais quitte \u00e0 avoir plein d’infos sur nos montres autant savoir \u00e0 quoi cela correspond !<\/p>\n\n\n\n
