Hypothesis
What is the metabolic response to high protein consumption in elite bodybuilders participating in high-intensity resistance exercise?
Conclusion
The study found that high protein intake in elite bodybuilders did not show obvious evidence of metabolic acidosis, suggesting that resistance exercise and adequate mineral supplementation may mitigate negative effects.
Supporting Evidence
- Participants consumed an average of 4.3 g/kg BW/day of protein, significantly higher than recommended levels.
- Urinary excretion of urea nitrogen and creatinine was elevated, indicating high rates of protein metabolism.
- Despite high protein intake, no clear evidence of metabolic acidosis was observed in the subjects.
Takeaway
Eating a lot of protein can change how your body works, but for bodybuilders who exercise a lot and take enough minerals, it might not be as bad as we thought.
Methodology
The study involved anthropometry, blood and urinary analysis, and dietary assessment of eight elite Korean bodybuilders aged 18 to 25.
Limitations
The study had a small sample size and was cross-sectional, limiting causal inferences.
Participant Demographics
Eight elite Korean bodybuilders aged 18 to 25, training for competitions for over two years.
