Tokyo, Sept. 17 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000059101) titled 'Biomechanical analysis of the inside-of-the-foot kick focusing on the ground reaction force and center of pressure of the support leg under varying approach angles' on Sept. 16.

Study Type: Interventional

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

Primary Sponsor: Institute - Gunma University

Condition: Condition - Healthy adult subjects with more than six years of soccer experience at the junior high and high school levels, with the right lower limb as the dominant leg, and without any orthopedic disorders of the lower extremities Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - This study investigates how different approach angles affect body posture during the inside-of-the-foot kick in soccer. The inside kick is mainly used for accurate passes and short-range shots, while the instep kick is used for powerful shots and long passes. Prior research has shown that increasing the approach angle in instep kicks leads to greater lateral body inclination, but few studies have examined this in inside kicks. The present study focuses on support leg joint angles and ground reaction forces to clarify posture changes. The findings are expected to provide insights into postural control strategies, contributing to both performance improvement and injury prevention. Basic objectives2 - Others

Intervention: Interventions/Control_1 - A size 5 soccer ball (diameter: 22 cm) was used, and a circular target (diameter: 11 cm) was placed 3 m away. The participants wore sports innerwear (top and bottom) and their accustomed athletic shoes. Before the measurements, they performed 5 practice inside-of-the-foot kicks from each approach angle to familiarize themselves with the one-step approach on the force plate. During the kicking trials, participants were instructed to perform the movement with the intention of passing the ball to a teammate, to prevent the ball from rising, and to kick the ball as quickly as possible. A trial was considered successful when the ball hit any part of the target. The 3 experimental conditions were as follows: 1) inside-of-the-foot kick from a 0 approach angle, 2) inside-of-the-foot kick from a 45 approach angle, and 3) inside-of-the-foot kick from a 90 approach angle. For each condition, participants continued kicking until 5 successful trials were obtained. The order of the conditions was randomized. The total measurement time per participant was approximately 60 to 90 minutes.
