Is there a beneficial effect of a high-protein diet on body composition and strength capacity in physical active middle-aged individuals?-An eight-week randomized controlled trial.

Simultaneously, muscle mass (MM) tends to decrease with age, with a decline noticeable from the middle of the fourth decade of life. While physical activity is considered a modulator for maintaining MM, the interaction with nutrient uptake, especially protein intake, is getting more into focus.
