ich weiß nicht ob das hilft, aber das ist auch aus der von mir oben zitierten Studie. Wenn man das richtig verstehen will, muß man sich wohl doch intensiver mit Biochemie beschäftigen.

An obvious question that arises is what is the carbon source for glycogen synthesis in the absence of carbohydrate intake post-exercise? Although speculative, lactate and/or glycerol, which were two-fold higher at the end of exercise in LC athletes and then sharply decreased during recovery, may have provided a source of carbons for glycogen synthesis during recovery [32]. Lactate conversion to glycogen could occur directly (lactate glyconeogenesis) or indirectly via the Cori cycle. Interestingly, lactate and ketones are both transported across cell membranes by monocarboxylic acid transporters, which are upregulated after a ketogenic diet [33]. Lactate was shown to account for up to 18% of skeletal muscle glycogen synthesized after high-intensity exercise [34]. It could be that lactate rapidly replenished liver glycogen and it has an ability to maintain hepatic glucose output in the face of limited exogenous carbohydrate intake. Regardless of the mechanism, these results suggest that long-term consumption of a low-carbohydrate/high-fat diet in highly trained ultra-marathoners results in adaptations in the homeostatic regulation of muscle glycogen that acts to preserve levels similar to those observed when exogenous carbohydrate availability is high.

Vor allem muss man sich auch intensiv mit Englisch beschäftigen. Ich versuch mal durchzusteigen
