A total of 37 licensed female football players competing in the Turkish Women's Second League participated in the study. Participants were randomly assigned to an experimental group (n = 20) or a control group (n = 17). The study evaluates whether this integrated training approach enhances acceleration, force production, and neuromuscular control compared to regular team training alone.", 'detailedDescription': "Study Design and Participants The study involves 37 female football players from the Pendik Güven Women's Football Team (mean age 14.4 ± 1.4 years), licensed by the Turkish Football Federation. Participants were randomly assigned to an experimental group (n = 20) or a control group (n = 17).\n\nIntervention Protocol The experimental group completed an Exer-Genie®-assisted sprint and ABC drill training program twice per week for eight weeks (total of 16 sessions). Each session was performed after a standardized warm-up and consisted of six 30-m sprint runs and technical drills. The sprints were performed with resistance applied using the 60-m Exer-Genie® device, with resistance intensity set at 10% of each athlete's body weight. The control group continued with their regular team training only.Outcome Measures 1. Sprint Performance: Assessed via 0-10 m, 10-30 m, and 30 m sprint times using the SmartSpeed electronic timing gate system. 2. Hamstring Strength: Assessed using the NordBord Hamstring Testing System. Specifically, the ISO Prone (0°) protocol was used to measure isometric hamstring strength and impulse values. 3. Vertical Jump: Assessed via the Countermovement Jump (CMJ) test using the ForceDecks system to evaluate lower-limb explosive performance.Statistical Analysis Data were analyzed using repeated-measures ANOVA to evaluate time, group, and interaction effects, with a significance level set at p \\< 0.05."}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['CHILD'], 'maximumAge': '17 Years', 'minimumAge': '11 Years', 'healthyVolunteers': True, 'eligibilityCriteria': "Inclusion Criteria:\n\nFemale gender.\n\nLicensed football players competing in the Turkish Women's Second League.\n\nRegularly engaged in football training for at least two years.\n\nAged between 11 and 17 years.\n\nExclusion Criteria:\n\nHistory of recent musculoskeletal injury.\n\nAny chronic health condition that could affect athletic performance.\n\nIrregular attendance to the training sessions during the study period."}, 'identificationModule': {'nctId': 'NCT07274566', 'briefTitle': 'The Effects of an 8-Week Exer-Genie-Assisted Speed and ABC Drill Training Program on Speed, Hamstring Strength, and Vertical Jump Performance in Female Football Players', 'organization': {'class': 'OTHER', 'fullName': 'Istanbul Rumeli University'}, 'officialTitle': 'The Effects of an 8-Week Exer-Genie-Assisted Speed and ABC Drill Training Program on Speed, Hamstring Strength, and Vertical Jump Performance in Female Football Players', 'orgStudyIdInfo': {'id': 'EXERGENIE-FOOTBALL-2025'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Experimental Group', 'description': 'Participants in this group performed an Exer-Genie®-assisted sprint and agility-balance-coordination (ABC drill) training program twice per week for eight weeks in addition to their warm-up routine.', 'interventionNames': ['Other: Exer-Genie® Training Protocol']}, {'type': 'NO_INTERVENTION', 'label': 'Control Group', 'description': 'Participants in this group continued with their regular team football training only and did not receive the Exer-Genie® resistance training.'}], 'interventions': [{'name': 'Exer-Genie® Training Protocol', 'type': 'OTHER', 'description': "The protocol consisted of six 30-m sprint runs performed with resistance applied using the 60-m Exer-Genie® device.
