Tokyo, June 20 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000061977) titled 'Effects of running speed and foot strike pattern on knee ligament loading' on June 19.

Study Type: Interventional

Study Design: Basic Design - Single arm Randomization - Non-randomized Blinding - Open -no one is blinded Control - Self control

Primary Sponsor: Institute - Niigata University of Health and Welfare

Condition: Condition - Healthy adults Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - The purpose of this study is to investigate the effects of different running speeds and foot strike patterns (rearfoot strike, midfoot strike, and forefoot strike) on lower-extremity biomechanical variables associated with anterior cruciate ligament (ACL) loading in healthy adults.

Running biomechanics will be assessed using a three-dimensional motion analysis system and force plates. Biomechanical variables, including knee joint angles, joint moments, and ground reaction forces, will be calculated. By comparing these variables across different running speeds and foot strike patterns, this study aims to identify mechanical characteristics associated with ACL injury risk and to provide evidence that may contribute to the prevention of primary ACL injuries and secondary ACL reinjuries. Basic objectives2 - Others

Intervention: Interventions/Control_1 - Participants will perform running trials under different running speed conditions (2.5 m/s, 3.5 m/s, and 4.5 m/s) and foot strike pattern conditions (rearfoot strike, midfoot strike, and forefoot strike) in a laboratory equipped with a three-dimensional motion capture system and force plates. Running biomechanics will be assessed using a motion capture system, force plates, and photocells. Lower-extremity kinematic and kinetic data will be collected during running. Outcome measures will include peak vertical ground reaction force, peak knee extension moment, knee flexion angle, knee valgus moment, knee valgus angle, and hip adduction angle. These variables will be compared across running speed and foot strike conditions.

Eligibility: Age-lower limit - 18 years-old = Gender - Male and Female Key inclusion criteria - Healthy adults with no history of lower-extremity surgery and no current lower-extremity pain, injury, functional impairment, or physical condition that may affect running performance at the time of testing. Key exclusion criteria - History of neurological or orthopedic disorders. Any medical condition that may affect running biomechanics or performance. Physical illness or poor health condition on the day of testing. Inability to perform the instructed foot strike patterns during the running trials. Target Size - 20
