Effects of Protein Quality on Post-exercise Skeletal Muscle and Whole-body Protein Kinetics During Energy Deficit

2019-07-08 07:49:15 | BioPortfolio


The optimal EAA-containing protein format necessary to maximally stimulate muscle protein synthesis and optimize whole-body net protein balance during caloric deprivation has not been determined. This study will address that gap in knowledge by examining post, whole-body exercise muscle and whole-body protein kinetic responses to ingesting varying EAA-containing protein formats after a 5 day period of negative energy balance. This study will provide the initial evidence to support the development of a recovery-based food product for military combat rations.


Ten resistance-trained adults will complete this ~55-d randomized, cross-over study. Participants will participate in three, non-consecutive 5-d controlled energy deficit periods, each separated by a 14-d washout period (i.e., sufficient time to restore nitrogen and metabolic homeostasis after moderate weight loss). Post-exercise (whole-body exercise model) muscle protein synthesis (MPS) and whole-body protein turnover responses to varying EAA-containing protein formats will be determined the morning after completing the 5-d energy deficit.

Medical and Biotech [MESH] Definitions

The protein components of milk obtained from the whey.

A major protein fraction of milk obtained from the WHEY.

The major protein constituents of milk are CASEINS and whey proteins such as LACTALBUMIN and LACTOGLOBULINS. IMMUNOGLOBULINS occur in high concentrations in COLOSTRUM and in relatively lower concentrations in milk. (Singleton and Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed, p554)

A sequence-specific DNA-binding protein that plays an essential role as a global regulator of yeast cell cycle control. It contains a 56 amino acid MADS-box domain within the N-terminal of the protein and is one of the four founder proteins that structurally define the superfamily of MADS DOMAIN PROTEINS.

The naturally occurring or experimentally induced replacement of one or more AMINO ACIDS in a protein with another. If a functionally equivalent amino acid is substituted, the protein may retain wild-type activity. Substitution may also diminish, enhance, or eliminate protein function. Experimentally induced substitution is often used to study enzyme activities and binding site properties.
