Abstract

IntroductionIn this study we investigated the impact of whey protein hydrolysate and maltodextrin (WPH) intake on intramuscular connective tissue (IMCT) protein fractional synthesis rate (FSR) after maximal shortening and lengthening contractions.Methods Twenty young men were randomized to receive either WPH or maltodextrin [carbohydrate (CHO)] immediately after completion of unilateral shortening and lengthening knee extensions. Ring-13C6-phenylalanine was infused, and muscle biopsies were obtained. IMCT protein FSR was measured at 1–5, as well as 1–3 and 3–5 hours after contractions and nutrient intake.Results During the 1–3-hour recovery, lengthening contractions resulted in a higher FSR than shortening contractions (P
