[email protected]; Tel.: +47-712-14000 Abstract: Age-related muscle wasting can compromise functional abilities of the elderly. Protein in- take stimulates muscle protein synthesis; however, ageing muscle is more resistant to stimuli. This double-blinded, randomized, controlled trial is one of the first registered studies to evalu- ate the effects of a supplement of marine protein hydrolysate (MPH) on measures of physical function and strength. Eighty-six older adults received nutritional supplements containing 3 g of MPH or Citation: Nygård, L.K.; Mundal, I.; a placebo for up to 12 months.
