Summary

This is a randomized controlled trial aimed to investigate the effects of different supplementary protein sources on muscle adaptations to resistance exercise. Young, healthy, recreationally active participants consuming an omnivorous diet with protein intake within recommended dietary allowance (RDA) (i.e.; 0.8-1.0 g.kg-1. d-1) will be recruited to undergo a 12-wk supervised resistance training program in combination with the intake of three 15-g daily doses (45g. d-1 total) of either a mixed plant- (i.e.; soy and pea protein) or animal-based (i.e.; whey protein) protein in drink form as a supplementary source of protein to their main meals of the day (i.e.; breakfast, lunch, and dinner). Before (PRE) and after (POST) the 12-wk intervention, participants will be assessed for body composition by dual-energy X-ray absorptiometry (DXA), muscle cross-sectional area (ultrasound) and fiber cross-sectional area (muscle biopsy), and maximal isotonic strength (1RM). Training consists of a resistance training (RT) program individually supervised by a researcher blinded to treatment in a laboratorial setting. Assessments will also be conducted in a blinded fashion.

DIETARY_SUPPLEMENT

Animal protein

Patients allocated to this arm will be submitted a supervised resistance training program in combination with the intake of three 15-g daily doses (45g. d- 1 total) animal-based protein (i.e.; whey protein) in drink form as a supplementary source of protein in their main meals of the day.

DIETARY_SUPPLEMENT

Plant Protein

Patients allocated to this arm will be submitted a supervised resistance training program in combination with the intake of three 15-g daily doses (45g. d- 1 total) mixed plant protein (i.e.; soy and pea) in drink form as a supplementary source of protein in their main meals of the day.
