Effects of Protein Quantity and Quality in Combination With Resistance Exercise on Muscle Mass and -Strength in Icelandic Elderly.

The mail goal of this randomized controlled, dietary intervention study is to investigate whether protein supplementation in combination with resistance exercise can increase muscle mass and strength in elderly. Loss of muscle mass and -strength is frequent in this group. Participants (N = 220, equal distribution between men and women) are randomized to one of three groups receiving different quantities and qualities of protein supplementation after exercise. The results of this study will be used to form recommendations regarding diet and exercise for the prevention of this frequent health problem in elderly.
