Combined Effects of Resistance Training and Nutritional Supplements in the Treatment of Sarcopenia
Combined Effects of Resistance Training and Nutritional Supplements in the Treatment of Sarcopenia
Age-related sarcopenia is associated with increased morbidity, mortality, disability and reduced resistance to metabolic stress. The aim of this study is to assess the effects of resistance training, associated or not with oral nutritional supplements, on skeletal muscle mass in sarcopenic subjects. This is a prospective randomised controlled single-centre study that will last two years, three months for a participant.
200 healthy elderly (70-80 years old) subjects will be screened for sarcopenia by dual energy X-ray absorptiometry. 128 sarcopenic subjects will be randomized into 4 groups:
Every subject will be assessed at the beginning and at the end of 12 weeks of intervention on:
Age-related sarcopenia is a common situation defined by muscle mass and function loss in an otherwise healthy elderly person. Epidemiological data from the USA show 49% of men and 72% of women to suffer from sarcopenia. Few data is available on the French population. Sarcopenia is associated with increased morbidity, mortality, disability and reduced resistance to metabolic stress. Resistance training and nutrition are two non-pharmaceutical methods that may be able to prevent several age-related condition.
The aim of this study is to assess the effects of resistance training, associated or not with oral nutritional supplements, on skeletal muscle mass (expressed as skeletal muscle mass index) in sarcopenic subjects. This is a prospective randomised controlled single-centre study that will last two years, three months for a participant.
200 healthy elderly (70-80 years old) subjects will be screened for sarcopenia by dual energy X-ray absorptiometry. 128 sarcopenic subjects will be randomized into 4 groups:
Every subject will be assessed at the beginning and at the end of 12 weeks of intervention on:
We expect to show that sarcopenia can be improved by 12 weeks of resistance training and that this improvement can be potentialized by oral nutritional supplements (with a stimulation of the mTOR pathway), and that oral nutritional supplements alone will affect neither muscle mass nor function.
