Participants were licensed youth goalkeepers with consistent sleep, diet, and training routines. Warm-up order was randomized and both participants and administrators were blinded to the condition. Flexibility, power, and balance were assessed using the sit-and-reach test, standing long jump, and Y Balance Test, respectively, with the best of three trials recorded. Heart rate was monitored to maintain internal load at 60-75% of age-predicted maximum. All sessions were supervised by a certified sports scientist, and anthropometric data were collected prior to testing. Ethical approval and informed consent were obtained.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['CHILD'], 'maximumAge': '15 Years', 'minimumAge': '14 Years', 'genderBased': True, 'genderDescription': 'Only male participants are eligible.', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Biologically male football goalkeepers\n* Aged 14-15 years\n* Actively competing in youth leagues\n* Minimum training experience of approximately 3-4 years\n* Free from chronic diseases or musculoskeletal injuries that could affect physical performance\n* Maintain regular sleep and dietary routines during the study period\n\nExclusion Criteria:\n\n* Current injuries\n* Chronic health conditions\n* Any physical limitations that could interfere with safe participation in warm-up protocols or performance testing'}, 'identificationModule': {'nctId': 'NCT07180667', 'briefTitle': "Warm-Up Effects on Adolescent Goalkeepers' Performance", 'organization': {'class': 'OTHER', 'fullName': 'Uşak University'}, 'officialTitle': 'Acute Effects of Different Warm-Up Protocols on Motor Performance in Adolescent Football Goalkeepers: A Randomised Crossover Study', 'orgStudyIdInfo': {'id': '207-01-08'}, 'secondaryIdInfos': [{'id': 'Uşak University', 'type': 'OTHER', 'domain': '207-01-08'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Arm 1: Aerobic Running Warm-Up (AR)', 'description': 'Participants perform a 15-minute aerobic running protocol with heart rate maintained at 60-75% of age-predicted maximum (HRₘₐₓ).
