Le mode 30-30 nature-humaine.ca/2026/11/fq… Trente secondes d’effort, trente secondes de récup, et on remet ça. Une formule d’entraînement par intervalles (EPI) très populaire pour développer le VO2max.

Quatre heures de tout doux en plus : ça change quoi, au juste? nature-humaine.ca/2026/11/fq… Si on exécute déjà 2 ou 3 séances hebdomadaires d'EPI, à quoi sert les autres séances mollo (séances de 'remplissage' disent, à la blague, certains de mes amis entraîneurs chevronnés)?

Existe-t-il une intensité d’entraînement qui favorise la perte de poids ? nature-humaine.ca/2016/09/pe… Fameux lipoxmax, ou fatmax. Il existe, mais il ne sert à rien pour qui veut se débarrasser de soucis adipeux!

Endurance athletes: Do you prefer a keto- or carb-based approach to nutrition? From the eleventh episode of our first season, internationally recognized sports dietitian @LouiseMaryBurke weighs in. “You have to choose,” Burke explains to @gibalam and @mackinprof . “Do you want to maximize your fat-burning capacity? Or do you want to be a carbohydrate burning machine?” For endurance events like the marathon, keto definitely has its pros. But as Burke explains, it has its drawbacks as well. Catch up with our episode on Keto vs. carbs at the link below, and stay tuned for season two coming soon.

Complete Glucose Oxidation ⚡ An extraordinary masterpiece of cellular machinery. Essential for cellular survival, health and athletic performance, yet potentially devastating to our health when it malfunctions. The mitochondrial pyruvate carrier (MPC) and mitochondrial lactate oxidation complex (mLOC) will be highly studied in the next decade as they are central to understand glucose metabolism and cellular dysregulations in diseases like diabetes, cancer or Alzheimer’s. *For endocrinologists working with T2D patients please understand these mechanisms. They are key to understand and manage diabetes. This can be done today already.

But what about a dose (say 20g/hr) that would prevent hypoglycaemia? Key finding of the study is that hypoglycaemia due to glucose depletion in the small glucose pool is the (CHO) metabolic factor limiting performance in this type of exercise lasting 2-3 hours. (Continued)
Some have argued that 10 g of carbohydrate per hour is sufficient to prevent hypoglycaemia during exercise. Latest data from @HenryJMartyn @JamesyMorton clearly disprove this. Absolute statements only need a single observation to be disproved. doi.org/10.1249/MSS.00000000…
