Summary

Circulating biomarkers are promising tools for the early diagnosis of aging-associated pathologies. Inflammation and immunity are associated with the risk of sarcopenia and frailty in elderly patients. The investigators investigate the effect of an adapted physical activity program on the metabolism and function of circulating immune cells and miRNA in frail and non-frail elderly subjects. Induced immune changes are analyzed together with that of motor abilities and of frailty status.

Detailed description

Circulating biomarkers are promising tools for early diagnosis of pathologies associated with aging. Inflammation and immunity are associated with the risk of sarcopenia and frailty in elderly patients. The investigators investigate the effect of an adapted physical activity program on the metabolism and function of circulating immune cells and miRNA in frail and non-frail elderly subjects. The main objective is to establish the link between biological markers of aging (immune cells phenotypes and function, miRNA) and motor capacities alteration/improvement. The secondary objectives are: (1) to characterize the functional and immunometabolic dimensions of frailty from objective indicators; (2) to propose a management system through adapted and individualized physical activity, based on objective indicators; (3) to evaluate the clinical impact of both frailty and its preventative management through physical activity; and (4) to identified new biomarkers of frailty. A total of 100 patients categorized as frail, pre-frail, and non-frail after a standardized geriatric evaluation are included in a comparative and interventional study. Exercise intervention consists in a 12-weeks physical activity program. Blood sample and physical/psychological functional measurements are performed before and after the 12-weeks physical activity program. ANOVA tests and correlational analysis will be performed. The finality of the study is to improve the medical prescription of physical activities in elderly patients.

Conditions

• Fragility

Interventions

Type	Name	Description
OTHER	adapted physical activity	The study begins with an evaluation of physical strenght and cognitive and psychometric assessment.Then, a personalized care will be offered in terms of adapted physical activity. The evaluation protocol will be performed again to measure the impact of physical activity three months after the first assessment.
