Protein Intake Research Suggests More for Bodybuilders


Exploring New and Old Health News Today – Protein Intake for healthy individuals taking part in strength training


A new research article suggest more protein is needed for bodybuilders on rest days. Current recommendations for protein intake from the Institute of Medicine (2005) states ‘no additional protein is suggested for healthy adults undertaking resistance or endurance exercise’. There’s always been a debate between fitness professionals, heath professionals and medical professionals about protein recommendations. This research paper was designed to answer a question regarding protein requirements for bodybuilders. The authors exact aim in their own words was “The aim of the study was to assess the dietary protein requirement of healthy young male bodybuilders”

The Research 

A recent paper by Bandegan, A,. et al (2017) from the American Society for Nutrition monitored young bodybuilders on a non-training day measuring oxidation of ingested L-phenylalaline to CO2 in response to graded protein intake (0.1 to 3.5 g per kg of bm per day). The Journal of Nutrition publishes peer-reviewed original research papers covering all aspects of experimental nutrition in humans and other animal species.


The authors concluded that protein recommendations for male body builders at rest on a non training day exceed current IOM recommendations by ~2.6 fold and estimated intakes were 1.7-2.2 g per kg of bm per day. This conclusion is in line with previous nitrogen balance research. The authors concluded that the institute of medicine need to reassess the protein recommendations for undertaking strength training.
