In this study, we aim to analyze the impact of running a 107,6 km mountain race in ultraendurance runners splitting our sample by individual's sex.\n\nTo do this, baseline measurements of the runners have been collected through stress tests and biochemical analyses of blood and urine samples. Indeed, a saliva sample was collected to isolated a genomic DNA sample of each runner.\n\nDuring the race anthropometrical, ventilatory and strength data was collected in three different moments and after crossing the finish line. Indeed, after completed the ultraendurance mountain race, blood and urine samples were taken at the finish line, as well as 24h and 48h post-race."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': '50 ultraendurance amateur runners, 19 females and 31 males.', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Healthy adults (\\>18 years old)\n* Volunteers should be finish at least one ultraendurance mountain race (\\>60km).\n\nExclusion Criteria:\n\n* Having heart disease\n* Having kidney disease\n* Taking a medication on an ongoing basis'}, 'identificationModule': {'nctId': 'NCT03990259', 'acronym': 'PTSW', 'briefTitle': 'Penyagolosa Trail Saludable Women', 'organization': {'class': 'OTHER', 'fullName': 'Universitat Jaume I'}, 'officialTitle': 'Penyagolosa Trail Saludable Women', 'orgStudyIdInfo': {'id': 'UJI_PTSW001'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Male', 'description': 'The male individuals of the study population', 'interventionNames': ['Other: Running the CSP Mountain Race']}, {'label': 'Female', 'description': 'The female individuals of the study population', 'interventionNames': ['Other: Running the CSP Mountain Race']}], 'interventions': [{'name': 'Running the CSP Mountain Race', 'type': 'OTHER', 'description': 'The runners completed a 107,6 km mountain race', 'armGroupLabels': ['Female', 'Male']}]}, 'contactsLocationsModule': {'locations': [{'zip': '12071', 'city': 'Castellon', 'country': 'Spain', 'facility': 'Universitat Jaume I', 'geoPoint': {'lat': 39.98567, 'lon': -0.04935}}], 'overallOfficials': [{'name': 'Carlos Hernando, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Universitat Jaume I'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO', 'description': "It is not planned to share participant's data"}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Universitat Jaume I', 'class': 'OTHER'}, 'collaborators': [{'name': 'Club Deportivo Marató i Mitja Castelló-Penyagolosa', 'class': 'UNKNOWN'}, {'name': 'Fundación Vithas-Nisa', 'class': 'UNKNOWN'}, {'name': 'Hospital Vithas-Nisa 9 de Octubre', 'class': 'UNKNOWN'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
