Är det alltså fortfarande viktigt att få i sig kolhydrater efter träningen, även om man deffar. Jag tränar oftast på eftermiddagen (typ mellan 17-19). Bör jag då fortfarande tänka på att det är efter träningen som de mesta av kolhydraterna ska ätas?

Absolut! Det är av största vikt att så snabbt som möjligt få i sig kolhydrat efter träning. Kolhydrater efter träning ökar fettförbränningen och att tillföra kolhydrat+protein
omedelbart är av kritisk betydelse.
"Probably the study best illustrating the effect of
nutrient timing on muscle tissue protein synthesis and
accretion is that by Levenhagen et al. (2001). These
researchers studied the effects of a
carbohydrate/protein supplement on protein synthesis
and degradation after a 60-minute moderate intensity
exercise bout of cycling. Subjects were given the
supplement immediately or 3-hours after exercise.
Protein degradation was unaffected by supplement
timing, but leg
protein synthesis was increased
approximately 3-fold above basal when
supplementation occurred immediately post exercise.
No increase in protein synthesis occurred when the
supplement was delayed 3-hours, and
only when the
supplement was immediately provided after exercise
was there a positive protein balance (the rate of
protein synthesis exceeded the rate of protein
degradation). It was also of interest to note that
when
supplementation occurred immediately compared to 3-
hours after exercise, there was a greater fat oxidation."
