Managing obesity effectively requires lifestyle and dietary modifications, including increased physical activity. Among the various exercise strategies, Moderate-Intensity Continuous Training (MICT) and High-Intensity Interval Training (HIIT) are widely recommended for reducing FM. Compared to MICT, HIIT is a time-efficient approach, often perceived as more enjoyable, and has been shown to promote greater total and abdominal fat loss in a shorter period. However, the precise mechanisms underlying this enhanced fat loss remain unclear.\n\nThis study aims to compare the acute effects of two isoenergetic exercise sessions - MICE (Moderate-Intensity Continuous Exercise) and HIIE (High-Intensity Interval Exercise) - on key physiological responses involved in fat mass loss. Specifically, we will assess plasma catecholamine levels during exercise and recovery, as well as oxygen consumption, substrate oxidation, and appetite over the 2-hour post-exercise period in young females with overweight or obesity. By elucidating the role of catecholaminergic stimulation as a potential regulator of fat mass loss, this research could provide valuable insights for optimizing exercise strategies in weight management and metabolic health.",[29,30],"Overweight and Obese Adults","High Intensity Interval Exercise (HIIE)",[32,33,34,35,36],"oxygen consumption","high intensity interval training","substrate oxydation","catecholamines","obesity","RECRUITING","2025-03-04",{"date":40,"type":41},"2025-03-11","ACTUAL",{"date":43,"type":41},"2025-02-01",{"date":45,"type":23},"2025-12-30",{"name":47,"class":48},"Laboratoire des Adaptations Métaboliques à l'Exercice en conditions Physiologiques et Pathologiques","OTHER",1,{"id":51,"slug":52,"hasResults":11,"nctId":53,"briefTitle":54,"officialTitle":55,"acronym":4,"eligibilityCriteria":56,"healthyVolunteers":17,"sex":57,"minAge":58,"maxAge":4,"enrollmentInfo":59,"targetDuration":4,"studyType":24,"phases":61,"briefSummary":62,"conditions":63,"keywords":64,"overallStatus":69,"whyStopped":4,"lastUpdateSubmitDate":70,"lastUpdatePostDateStruct":71,"startDateStruct":73,"completionDateStruct":75,"leadSponsor":77,"locationsCount":4},"100565033","time-at-vo2max-during-high-intensity-interval-training-100565033","NCT06636916","Time at VO2max During High-Intensity Interval Training","Time at VO2max During High-Intensity Interval Training Manipulating Work and Rest","Inclusion Criteria:\n\n* Middle and long distance track and field athletes\n\nExclusion Criteria:\n\n* Injured athletes","ALL","18 Years",{"count":60,"type":23},10,[26],"The project titled \"Time at VO2max During High-Intensity Interval Training Manipulating Work and Rest\" aims to investigate how different high-intensity interval training (HIIT) protocols influence the time athletes spend at or above 90% of their VO2max.
