Document Summary

The researchers fed subjects primarily high protein intake in this study, no one was fed low protein intake - might have artificially elevated requirements. The sedentary data suggests this happened because where the line intersects at 0. 75 protein intake is much higher than most sedentary people which is 0. 55-0. 6. If sedentary protein intake values are elevated, runners are also elevates = data not correct: however, other studies with lower protein intakes actually produced similar results. Whole body protein synthesis - study graph: this study looked group of sedentary individuals and strength trained athletes, and fed them 3 different levels of protein to measure protein synthesis across whole body. Low: 0. 9 g/kg/d protein intake that is needed for sedentary individuals but is below what previous studies estimated for strength athletes. Middle: 1. 4 g/kg/d is what requirements seem to be in strength trained athletes.
