Investigating the Consumption of Different Protein Rich Whole Food Sources on Muscle Growth in Trained Males and Females

Background To date, most of the literature investigating the role of dietary protein in muscle growth has focused on isolated protein sources. However, dietary protein is most commonly consumed within a whole food source. Consuming dietary protein within a whole food matrix may additionally stimulate muscle growth. The idea being, there may be other components within food, capable of producing a greater response.

Objectives: To assess the effect of consuming a variety of whole food sources, on the stimulation of muscle growth compared to an isolated protein source following a single bout of lower body resistance exercise.

Methods Young healthy resistance-trained volunteers will consume a protein rich whole food source, following a bout of lower body resistance exercise. Stable isotope IV infusions and repeated blood and muscle samples will be taken to assess protein digestion and absorption, as well as muscle protein synthesis rates.

Value of Research:

To determine whether whole food sources potentiate muscle protein synthesis rates (and to what extent across whole food sources) compared to an isolated protein source. In doing so, we can further investigate the nutrients involved that may be contributing to this effect.

Treatment and study plan

whole food sources

Dietary Supplement

Foods selected are naturally high in protein and consumed by the general population as part of a meal.

Primary outcomes

  1. Postprandial Muscle protein Synthetic Response following the ingestion of a protein rich whole food source.

    Time frame: 2 years

    84 participants will undergo a single bout of lower body exercise followed by the ingestion of one of the six protein rich whole food sources. Using stable isotope tracer methodology and muscle biopsy samples, the postprandial muscle protein synthetic response will be able to be calculated.
