The key issue is to understand why the biological aging of the skeletal muscle is so different between people.\n\nPrevious sarcopenia studies in Humans did not really focus on chronological aging, they were all based on a comparison between young and old people. No study considered inter-individual modifications (biological aging) in sarcopenia. Furthermore, few studies were associated in the same study to "omic", histological, and epigenetic data, to obtain integrated point of view of Human Sarcopenia.\n\nIn this study, mechanisms involved in biological aging of the skeletal muscle in aging people (same chronological age) will be specified.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['OLDER_ADULT'], 'maximumAge': '83 Years', 'minimumAge': '80 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'Patients are recruited in the Proof cohort (Barthélemy et al., 2007).', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Belonging to the Proof cohort\n* Between 80 and 83 years old\n* Informed consent signed\n* Genetic analyses consent signed\n* Subject affiliated or entitled to a social security scheme\n\nExclusion Criteria:\n\n* Anti coagulative treatment\n* Severe obesity (\\>35)\n* All chronic pathology requiring a treatment\n* Severe renal insufficiency (discovery less than 6 months)\n* Abnormal coagulation appraisal\n* Allergy to local anesthetics\n* Installation of a prosthetic hip and / or knee in the last six months\n* Senile dementia\n* Refusal of genetic study'}, 'identificationModule': {'nctId': 'NCT02675192', 'acronym': 'BioAge', 'briefTitle': 'Biological Aging of Skeletal Muscles in Humans', 'organization': {'class': 'OTHER', 'fullName': 'Centre Hospitalier Universitaire de Saint Etienne'}, 'officialTitle': 'Biological Aging of Skeletal Muscles in Humans, a Monocentric, Prospective Study', 'orgStudyIdInfo': {'id': '1508145'}, 'secondaryIdInfos': [{'id': '2015-A01484-45', 'type': 'OTHER', 'domain': 'ANSM'}]}, 'armsInterventionsModule': {'armGroups': [{'label': 'Proof cohort : muscular assessment', 'description': '* Clinical examination : Body weight, BMI, cardiac frequency, muscular examination,...\n* Blood appraisal : glycaemia, lipidic appraisal, leptin, albumin, coagulation, metabolome and epigenetic tests,...\n* Urinary collection : metabolome tests\n* Maximal voluntary quadriceps strength (MVC)\n* Checking muscle functional skills\n* Muscular biopsy', 'interventionNames': ['Other: Proof cohort : muscular assessment']}], 'interventions': [{'name': 'Proof cohort : muscular assessment', 'type': 'OTHER', 'description': 'Clinical examination, blood appraisal, urinary collection, MVC, checking muscle functional skills and muscular biopsy will be performed.', 'armGroupLabels': ['Proof cohort : muscular assessment']}]}, 'contactsLocationsModule': {'locations': [{'zip': '42100', 'city': 'Saint-Etienne', 'country': 'France', 'facility': 'Chu Saint Etienne', 'geoPoint': {'lat': 45.43389, 'lon': 4.39}}], 'overallOfficials': [{'name': 'FEASSON Léonard, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'CHU SAINT-ETIENNE'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Centre Hospitalier Universitaire de Saint Etienne', 'class': 'OTHER'}, 'collaborators': [{'name': 'Ecole Nationale Superieure Lyon', 'class': 'UNKNOWN'}, {'name': "Institut National de Recherche pour l'Agriculture, l'Alimentation et l'Environnement", 'class': 'OTHER'}, {'name': 'Region Rhone Alpes', 'class': 'UNKNOWN'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
