Tokyo, July 2 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000062111) titled 'Assessment of global biomechanics during movements in breakdance and evaluation of the effects of related factors: using a markerless motion capture system' on July 1.

Study Type: Interventional

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

Primary Sponsor: Institute - Ehime University

Condition: Condition - Breakdance movements Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - Breakdancing was included as an official-competition at the 2024 Paris Olympic Games and has attracted attention as a rapidly developing international competitive sport. However, because of its dynamic movements, breakdancing has been reported to have a higher incidence of traumatic injuries and overuse disorders compared with other dance genres. Nevertheless, the injury mechanisms associated with the fundamental and key movements of breakdancing have not yet been sufficiently elucidated. In addition, injury-prevention programs and support systems have not yet been established.

In recent years, motion capture systems have been reported to be useful methods for assessing global biomechanics, including in the medical field. Furthermore, markerless motion capture, which does not require body-surface markers, enables measurement in an environment close to natural conditions for participants while maintaining sufficient measurement accuracy. The purpose of this study is to elucidate the biomechanics of fundamental and key movements in breakdancing, as well as the mechanisms of injury occurrence, using the aforementioned markerless motion capture system. Through this study, we expect to identify the movements and factors that impose excessive loads on specific joints in breakdancing. Basic objectives2 - Others

Intervention: Interventions/Control_1 - After medical interviews and physical measurements, participants will be asked to perform designated fundamental and key breakdancing movements. During each movement, the range of motion of the extremity joints, joint angles, angular velocity, angular acceleration, joint moments, and whole-body center-of-mass sway will be measured using a markerless motion capture system.

Eligibility: Age-lower limit - 6 years-old <= Age-upper limit - Not applicable Gender - Male and Female Key inclusion criteria - Participants who meet all of the following criteria will be included: 1. Instructors or students belonging to a breakdancing school 2. Age 6 years or older 3. Ability of the participant or a legally authorized representative to respond to the medical interview 4. Healthy individuals 5. Ability to maintain or perform fundamental breakdancing postures, including handstand, chair freeze, and footwork, for at least 5 seconds each 6. Ability to perform at least five consecutive rotations of the basic spinning technique known as the windmill Key exclusion criteria - Participants who meet any of the following criteria will be excluded: 1. Individuals who are unable to respond to the medical interview, except for children whose legally authorized representatives are able to respond. 2. Individuals who have an injury under treatment at the time of study participation. 3. Individuals who have musculoskeletal diseases or disorders related to dance movements at the time of study participation. 4. Individuals who are judged by the investigators to have difficulty participating in the study or undergoing the measurements. 5. Individuals who are judged by the investigators to have severe psychosocial disorders that may substantially affect the study results or their participation in the study. Target Size - 100
