The main questions this study aims to answer are:\n\n* Does plyometric training performed on sand improve dynamic postural balance more than training performed on a firm surface?\n* Does plyometric training performed on sand reduce lower-limb muscle soreness compared with training performed on a firm surface?\n\nResearchers will compare a firm-ground plyometric training group, a sand-surface plyometric training group, and a control group to evaluate the effects of training surfaces on physical performance and recovery.\n\nParticipants will:\n\n* Perform plyometric training sessions three times per week for eight weeks (experimental groups).\n* Complete performance tests, including vertical jumps, sprint tests, change-of-direction speed tests, and the Y-Balance Test, before and after the intervention.\n* Report perceived lower-limb muscle soreness following training sessions.', 'detailedDescription': 'Detailed Description\n\nThis prospective randomised controlled study investigates the effects of plyometric training performed on two different training surfaces (firm ground vs sand) on neuromuscular performance, dynamic postural balance, and lower-limb muscle soreness in young active males. Participants are randomly assigned to one of three groups: a firm-ground plyometric training group, a sand-based plyometric training group, or a control group that continues regular activities without additional training.\n\nThe intervention lasts eight weeks, with three supervised training sessions per week for the experimental groups. The plyometric training program includes multidirectional exercises, such as forward bounding jumps, lateral hurdle jumps, and forward hurdle jumps, with progressive increases in training volume throughout the intervention.\n\nNeuromuscular performance is evaluated using the standing long jump, squat jump, countermovement jump, sprint tests (10 m and 20 m), and a change-of-direction speed test (T-test). Dynamic postural balance is assessed using the Y-Balance Test for both dominant and non-dominant stance legs. Lower-limb muscle soreness is recorded after each training session using a 7-point Likert scale.\n\nPre- and post-intervention assessments are conducted to determine the effects of training surfaces on performance outcomes, balance adaptations, and perceived muscle soreness.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT'], 'maximumAge': '20 Years', 'minimumAge': '19 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Male university students aged between 19 and 20 years\n* Physically active and regularly participating in practical sport science activities\n* Free from lower-limb injuries during the previous six months\n* Provided written informed consent to participate in the study\n\nExclusion Criteria:\n\n* Presence of any musculoskeletal injury affecting the lower limbs or lower back\n* Any neurological or balance disorder that could affect test performance\n* Participation in another structured strength or plyometric training program during the study period\n* Failure to complete the training intervention or testing sessions'}, 'identificationModule': {'nctId': 'NCT07489404', 'acronym': 'PST-SF', 'briefTitle': 'Plyometric Training on Sand vs Firm Ground in Young Adults', 'organization': {'class': 'OTHER', 'fullName': 'University of Manouba'}, 'officialTitle': 'Influence of Training Surface (Firm Ground vs Sand) on Neuromuscular Performance, Dynamic Postural Balance, and Muscle Soreness Following Plyometric Training in Young Active Males', 'orgStudyIdInfo': {'id': 'PTU-19012026'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Sand-Surface Plyometric Training', 'description': 'Participants performed a multidirectional plyometric training program on dry sand three times per week for eight weeks.', 'interventionNames': ['Behavioral: Plyometric Training on Sand']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Firm-Ground Plyometric Training', 'description': 'Participants performed a multidirectional plyometric training program on a firm surface three times a week for eight weeks.', 'interventionNames': ['Behavioral: Plyometric Training on Sand']}, {'type': 'NO_INTERVENTION', 'label': 'control group', 'description': 'Participants continued their usual activities and did not perform additional plyometric training during the eight-week study period.'}], 'interventions': [{'name': 'Plyometric Training on Sand', 'type': 'BEHAVIORAL', 'otherNames': ['Sand-Based Plyometric Training'], 'description': 'Participants performed a multidirectional plyometric training program on dry sand three times a week for eight weeks.
