[Musculoskeletal factors, sarcopenia and falls in old age].

Falls in older adults are a major public health problem with a high incidence and severe consequences for the older individual. The age-related loss of muscle strength as well as muscle mass and muscle function (sarcopenia) are i) risk factors for falling, ii) associated with physical function and iii) markers of the frailty syndrome. Muscle function appears to play a bigger role than muscle mass. The operationalization of sarcopenia using the European Working Group on Sarcopenia in Older People (EWGSOP) algorithm is consistently associated with falling events. Structured physical exercise plays the key role in the prevention of falls and the management of functional decline caused by sarcopenia and frailty. The combined supplementation with proteins and vitamin D supports muscle protein synthesis in undersupplied persons and improves aspects of physical function.
