Normal fluctuations in Muscle Protein Synthesis and Muscle Protein Breakdown rates throughout the day in response to eating a protein containing meal and the effect this has on net protein balance. Protein Requirements to stimulate myofibrillar protein synthesis rates in young and aging populations are described in g/kg of lean body mass These protein meal requirements should be spread equally throughout the day (i.e., 4–5 meal times) to facilitate non-hypertrophic protein remodeling and counterbalance fasting-state protein losses that occurred in between meals (81). MPS, Muscle protein synthesis; MPB, Muscle protein breakdown; LBM, Lean body mass.
