Epidemiological data from Europe have shown that around 30% of subjects aged over 65 years of age are pre-frail, and 15% are frail. Recent research has demonstrated that identifying frailty and implementing preventive measures can help to slow cognitive decline. Screening and treating frailty seem to be a good start towards preventing dependency. On the premise that this frailty is the result of more pronounced tissue alterations in certain elderly subjects, assessment of post-translational modification derived products (PTMDP) represents an innovative evaluation method. These include advanced glycation end-products (AGE), and carbamylation-derived products (homocitrulline). Indeed, the intensity of these modifications increases with ageing, and assessing the products resulting from these alterations could show the existence of differences according to frailty status. This would make it possible to adapt treatment accordingly in elderly subjects.
Ageing is the primary risk factor for most chronic diseases including type 2 diabetes mellitus. Sarcopenia and muscular mitochondrial dysfunction with aging are crucial mechanisms leading to decreased exercise tolerance and worsened insulin sensitivity. Thus, metabolic disease and frailty, which limits physical mobility as well as quality of life, share common cellular mechanisms. The investigators will test the hypothesis that a combination of normobaric hypoxia and exercise training elicits a synergistic effect on age-associated metabolic skeletal muscle dysfunction and the investigators will address the molecular mechanisms. In a randomized clinical study, the investigators will compare normoxic and hypoxic training conditions in elderly subjects. Outcome measures will focus on whole body insulin sensitivity and mitochondrial responses in skeletal muscle before and after the 8-week training intervention.
