Should Competitive Bodybuilders Ingest More Protein than Current Evidence-Based Recommendations?

Area of Science:

• Sports Nutrition
• Exercise Physiology
• Nutritional Biochemistry

Background:

• Bodybuilding requires high muscularity and low body fat.
• Protein is crucial for muscle growth (hypertrophy) and lean mass accretion.
• General recommendations for protein intake in resistance training range from 1.4 to 2.0 g/kg/day.

Purpose of the Study:

• To critically evaluate the evidence for higher protein intake in competitive bodybuilders.
• To determine if current protein recommendations are adequate for this specific population.
• To identify research gaps regarding protein consumption in bodybuilding.

Main Methods:

• This is an opinion article, critically evaluating existing scientific literature.
• The review focuses on studies related to protein intake, muscle hypertrophy, and body composition.
• Evidence synthesis and expert opinion form the basis of the evaluation.

Main Results:

• Competitive bodybuilders often consume protein in excess of general guidelines.
• Existing research suggests potential benefits of higher protein intake for this group.
• Direct studies on competitive bodybuilders' protein needs are limited.

Conclusions:

• Competitive bodybuilders might require more protein than recreationally trained individuals.
• The optimal protein intake for competitive bodybuilders remains uncertain due to insufficient direct research.
• Further investigation is warranted to establish evidence-based protein recommendations for bodybuilding.
