Quick Summary

In this randomized controlled trial in older men, a high-protein diet enhanced resistance-exercise-induced adaptations, as compared to a low-protein diet.

What was studied?

The effects of low-protein and high-protein diets in combination with a resistance exercise intervention in older men.

The primary outcome was the change in lean mass (measured via bioelectric impedance analysis). The secondary outcomes were body fat percentage, muscular endurance (measured via the number of repetitions completed during 1 set of chest press and leg press performed to muscular failure using 75% of 1-repetition maximum (1RM) load), muscular strength (measured via 1RM tests for the chest press and leg press), power output during a 30-second Wingate test, levels of liver enzymes, blood lipids, and markers of kidney function (i.e., serum levels of creatinine and urea).
