Ingestion of a lipid-rich meat matrix blunts the postexercise increase of myofibrillar protein synthesis rates in healthy adults: a randomized controlled trial.

ABSTRACT:

Background

There is considerable variation in the anabolic action of ingesting protein-dense foods on the stimulation of postprandial myofibrillar protein synthesis rates (MPS) despite ingesting similar amounts of protein and essential amino acids (EAA).

Objectives

This study aims to determine the effects of consuming high-fat pork (HFP), low-fat pork (LFP), or a carbohydrate control (CHO) on the MPS response.

Methods

In a semicrossover design, 16 physically active adults (25 ± 5 y; 25.0 ± 2.3 kg/m²; 12M, 4F) received primed-constant infusions of L-[ring-¹³C₆]phenylalanine and performed an acute bout of resistance exercise. Following exercise, participants ingested either HFP (266 kcal, 20 g protein, 20.6 g fat), LFP (120 kcal, 20 g pr
