The effects of 8 weeks of whey or rice protein supplementation on body composition and exercise performance

Nutr J. 2013 Jun 20:12:86. doi: 10.1186/1475-2891-12-86.


Consumption of moderate amounts of animal-derived protein has been shown to differently influence skeletal muscle hypertrophy during resistance training when compared with nitrogenous and isoenergetic amounts of plant-based protein administered in small to moderate doses. Therefore, the purpose of the study was to determine if the post-exercise consumption of rice protein isolate could increase recovery and elicit adequate changes in body composition compared to equally dosed whey protein isolate if given in large, isocaloric doses.
