Sarcopenia Physical Activity and Metabolomic

Muscle failure (sarcopenia or dynapenia) is a factor of frailty and therefore, ultimately, of loss of autonomy in the elderly. Currently, no biomarker of muscle failure has a high sensitivity, specificity and positive predictive value. Several results, although preliminary, suggest that metabolomics could facilitate the early identification of frail patients, allowing the implementation of primary prevention strategies. Untargeted high-resolution metabolomics analysis would identify discriminative biomarkers and biological mechanisms associated with frailty. Finally, the hypothesis that metabolic signatures can be identified as risk factors for the development of age-related dynapenia should be tested in a longitudinal design.
