In this setup, three cones were placed in a straight line, each 4.57 meters apart. A fourth cone was placed 9.14 meters perpendicular to the middle cone. Participants were instructed to sprint forward to the center cone, shuffle laterally to each side cone, and then backpedal to the start. The time taken to complete the course was measured using electronic timing gates. Shorter times indicate better agility performance .'}, {'measure': 'Dynamic Balance Test (Y-Balance Test)', 'timeFrame': 'It was measured separately in all three phases of exercise.

Participants stood barefoot on one leg, placing the stance foot at the center of a Y-shaped grid, with toes behind the starting line.

The participant was then asked to close their eyes and actively replicate the target position. The angular deviation from the target was recorded as the proprioceptive error.

From a standing position, participants performed a maximal vertical jump and touched the wall at the peak of their jump. The difference between the jump reach and the standing reach height was calculated and recorded as the jump height. Three trials were conducted, and the highest value was used for analysis.

Understanding these effects is critical for optimizing warm-up protocols to enhance athletic performance and reduce injury risk in this population.\n\nMethods:\n\nTwenty-five male professional youth football players under the age of 18 (mean age 16.5 ± 1.2 years) were randomly selected for this study. Each participant underwent assessments during three distinct muscle states: resting, after warm-up, and post-training fatigue. Knee joint proprioception was evaluated at a 30° angle using a digital inclinometer to measure joint position sense accuracy. Dynamic balance was assessed through the Y-balance test in three directions: anterior, posteromedial, and posterolateral. Explosive power was measured using the Sargent vertical jump test, while agility was tested with the T-test. All measurements were performed in each muscle condition to compare performance across the different warm-up phases.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['CHILD'], 'maximumAge': '17 Years', 'minimumAge': '14 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:The study included young athletes with at least 3 years of club-level football experience who trained at least 5 days a week for 90 minutes -\n\nExclusion Criteria:Individuals with knee pain or a history of knee joint surgery were excluded from this study.\n\n\\-'}, 'identificationModule': {'nctId': 'NCT07284706', 'briefTitle': 'Warm-Up Phases and Neuromuscular Performance', 'organization': {'class': 'OTHER', 'fullName': 'Necmettin Erbakan University'}, 'officialTitle': 'Effects of Muscle Warm-Up Phases on Proprioception, Vertical Jump, Agility, and Balance in Professional Youth Soccer Players: A Randomized Study', 'orgStudyIdInfo': {'id': 'NEU-PT2025-02'}, 'secondaryIdInfos': [{'id': 'Necmettin Erbakan University', 'type': 'OTHER', 'domain': 'Necmettin Erbakan University'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Exercise Program', 'interventionNames': ['Other: three warming phases of the muscle']}], 'interventions': [{'name': 'three warming phases of the muscle', 'type': 'OTHER', 'description': 'All assessments will be measured in three warming phases of the muscle.
