l'abstract riporta:
INTRODUZIONE: The purpose of this study was to determine
whether endurance cycling performance and postexercise muscle damage were altered when consuming a carbohydrate and protein beverage (CHOP; 7.3% and 1.8% concentrations) versus a carbohydrate-only (CHO; 7.3%) beverage....
CONCLUSIONE: carbohydrate beverage with additional protein calories produced significant improvements in time to fatigue and reductions in muscle damage in endurance athletes. Further research is necessary to determine whether these effects were the result of higher total caloric content of the CHOP beverage or due to specific protein-mediated mechanisms."
Però come leggi non è chiaro se il vantaggio è dovuto alle calorie extra o a qualche azione specifica delle proteine.
