A normal working day from of 12h is compared to: (i) a working day during which the participants have to get up at least 5 min/hour (sit-and-stand desk), (ii) a working day during which they can use a cycloergometer installed under the desk. Conditions will be random using Latin Square design with stratification between sequences cross-over design on occupation (EMD vs. firefighters).\n\nThe heart rate variability (measured using Zephyr®), the electrodermal activity (Empatica® E4), the level of physical activity (Actigraph®) as well as the blood sugar (Freestyle®) will be measured continuously during the 12 hours of work and the night after except for Actigraph® and Freestyle® device that will be let one week. Blood and saliva samples will be collected on each working day, at the beginning and end of the day i.e. two measures for blood samples, and every three hours i.e. 5 measures for saliva sampling. Participants will have to complete a detailed questionnaire to identify the particular events (vital emergencies, etc.) that may influence the parameters measured.\n\nParticipants will be asked to answer a general questionnaire once at the start of the study that will cover different aspects:\n\n* Sociodemographic,\n* Visual analogue scale (VAS) related to psychosocial factors : stress at home, burnout / burnout, decision latitude / autonomy at work, psychological demands at work (workload), support from the hierarchy, support from co-workers, family support, job satisfaction with regard to effort, commitment to work, addiction to work, quality of life, need for psychological support,\n* Eating habits.\n\nThey will then have to answer a short questionnaire at the beginning and at the end of each measurement day. It will cover different aspects:\n\n* Four VAS (stress level, fatigue, anxiety, mood),\n* Physical activity and sedentary lifestyle (number of hours of physical activity and sitting during the last 24 hours),\n* Daily consumption (tobacco, alcohol, cannabis, coffee, tea).'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Emergency medical dispatchers or firefighters from the departmental fire and rescue operational center (CODIS).\n* Person able to give an informed consent to participate in research\n* Affiliated with a Social Security scheme.\n* Being able to use the sit-stand desk and the cycle ergometer\n\nExclusion Criteria:\n\n* Non-affiliated to a health insurance,\n* Protected persons (minors, pregnant women, breastfeeding women, guardianship, curatorship, deprived of freedoms, safeguard of justice),\n* Refusal to participate.'}, 'identificationModule': {'nctId': 'NCT05931406', 'acronym': 'SECODIS', 'briefTitle': 'Effects of a Sedentary Behaviors at Work on Health in Emergency Medical Dispatchers and CODIS Operators (SECODIS)', 'organization': {'class': 'OTHER', 'fullName': 'University Hospital, Clermont-Ferrand'}, 'officialTitle': 'Effects of a Sedentary Behaviors at Work on Health in Emergency Medical Dispatchers and CODIS Operators', 'orgStudyIdInfo': {'id': 'RBHP 2022 DUTHEIL'}, 'secondaryIdInfos': [{'id': '2022-A02730-43', 'type': 'OTHER', 'domain': 'ANSM'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Emergency medical dispatchers', 'interventionNames': ['Behavioral: Control', 'Behavioral: Sit-and-stand desk', 'Behavioral: Cycloergometer']}, {'type': 'EXPERIMENTAL', 'label': 'Firefighter', 'interventionNames': ['Behavioral: Control', 'Behavioral: Sit-and-stand desk', 'Behavioral: Cycloergometer']}], 'interventions': [{'name': 'Control', 'type': 'BEHAVIORAL', 'description': 'A normal working day from of 12h', 'armGroupLabels': ['Emergency medical dispatchers', 'Firefighter']}, {'name': 'Sit-and-stand desk', 'type': 'BEHAVIORAL', 'description': 'a working day during which the participants have to get up at least 5 min/hour', 'armGroupLabels': ['Emergency medical dispatchers', 'Firefighter']}, {'name': 'Cycloergometer', 'type': 'BEHAVIORAL', 'description': 'a working day during which they can use a cycloergometer installed under the desk', 'armGroupLabels': ['Emergency medical dispatchers', 'Firefighter']}]}, 'contactsLocationsModule': {'locations': [{'city': 'Clermont-Ferrand', 'status': 'RECRUITING', 'country': 'France', 'contacts': [{'name': 'Lise Laclautre', 'role': 'CONTACT'}, {'name': 'Frédéric Dutheil', 'role': 'PRINCIPAL_INVESTIGATOR'}], 'facility': 'CHU clermont-ferrand', 'geoPoint': {'lat': 45.77969, 'lon': 3.08682}}], 'centralContacts': [{'name': 'Lise LACLAUTRE', 'role': 'CONTACT', 'email': 'promo_interne_drci@chu-clermontferrand.fr', 'phone': '334.73.754.963'}], 'overallOfficials': [{'name': 'Fréderic DUTHEIL', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'fdutheil@chu-clermontferrand.fr'}]}, 'ipdSharingStatementModule': {'infoTypes': ['STUDY_PROTOCOL'], 'ipdSharing': 'YES', 'description': 'After contacting the corresponding author and signing a data sharing agreement, investigators will make available the documents and personal data strictly necessary in accordance with laws and regulations (Articles L.1121-3 and R.5121-13 of the Code of Public Health).'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University Hospital, Clermont-Ferrand', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
