Cwiczenia na czczo a katabolizm
W tym tekście chcę uspokoić te osoby, które trenują z rana a nie mają ochoty na jakikolwiek posiłek przed-treningowy.
Ogólnie straszy się katabolizmem mięśni podczas wysiłku na czczo. W poniższych badaniach przedstawiam dowody na to że podczas wysiłku na czczo MPB - muscle protein breakdown jest minimalny. Więc nie trzeba się martwić tym że "palimy" mięśnie trenując w stanie po trawiennym.
In addition, we have shown that muscle PS and PB are not significantly affected during resistance exercise.

in the postabsorptive state; in these studies, phenylalanine rate of appearance, indicative of protein breakdown, was not elevated above rest
jap.physiology.org/content/106/6/2026.long#sec-3
Protein synthesis and breakdown increased simultaneously but to a different extent. Synthesis increased by 100%, whereas breakdown increased by only 50%. Consequently, protein balance( synthesis minus breakdown) improved after exercise(becoming not signifcatly different from zero) but did not shift to a positive value. These result suggest that physical exercise can restrain net muscle protein catabolism but does not directly promote net protein deposition in the postabsortive state.
