Aging is a natural and multi-factorial phenomenon characterized by the accumulation of degenerative processes that are in turn underpinned by multiple alterations and damage within cellular and molecular pathways. The prevention of age related physical and mental impairment, as well as the reduction of chronic diseases is one of the main objectives to improve quality of life and reduce the costs for healthcare in the elderly. This is important since the proportion of people over 60 years of age will be doubled by 2050. The age-related loss of muscle mass, function and strength—termed either as sarcopenia or dynapenia—has a profound impact on mobility in the elderly. This loss of physical function capabilities compromises the ability to independently perform every-day activities. There is profound evidence that there is a close interaction of physical activity, diet, function and aging. Whilst all elements of dietary intake are critical for the maintenance of muscle mass, it is the regular adequate consumption of protein, that is essential to stimulate protein synthesis. One other important player is regular physical activity to preserve muscle function on a high level. Other very important nutrients in the aging populations are e.g. vitamin D, iron, zinc, folic acid or vitamin B12. Importantly, both, physical activity and a well-balanced diet are the key factors for a good and long lasting (muscle) health and when combined, their synergistic impact on muscle tissue is even stronger. Within the talk I will present international as well as own data such as from the ACTIVE AGEING study, where we performed supervised resistance training in 117 institutionalized elderly (mean age 82.8±6.0 years) over 6 months with and without a nutritional intervention. In the recently finished NUTRIAGING studies we compared protein or vitamin D at different intake levels with and without supervised resistance training on various health marker.
