Sarcopenia is a pathophysiological process associated with aging and some metabolic conditions characterized by progressive muscle tissue loss, which may lead to loss of strangth and performance and increase risk of falls and fractures, physical disability and premature death. Therefore, it is necessary to identify personalized programs of physical activity and supplementation for elderly population in order to improve their physical functions, muscle strengh and body composition.

With the present project we aime to assess the effect of a feasible home-based exercise program coupled with food supplementation to improve muscle strength, muscle volume and muscle physical performance potentially associated with sarcopenia in elderly people.
