Design outcomes

Primary

Measure	Time frame
Change in muscle mass after the 3-month training period and supplementation of collagen peptides compared to placebo supplementation verified by DEXA measurement	—

Secondary

Measure	Time frame
Secondary outcomes are improving arm and leg strength, changes in fat mass and changes in the metabolic risk profile (waist circumference, triglycerides, HDL / LDL cholesterol, blood pressure) after the 3-month training period. Additionally it is examined to which extent the effects are influenced by the oral administration of whey protein and in which extent they draw a distinction between taking whey protein and collagen peptides or placebo.	—
