Koji Kaneoka 교수의 연구실은 체육과학과 운동의학 분야에서 신체의 운동 기계학적 특성과 근육 기능의 상호작용을 중심으로 연구를 진행하고 있습니다. 특히 자세 유지, 운동 손상 메커니즘, 근육 공진화(muscle synergy) 및 근육 활동 패tern 분석에 초점을 맞추고 있으며, 수영, 농구, 테니스, 스트레스 테스트 운동 등 다양한 스포츠 활동에서의 체력 기반 손상 예방 전략을 모색하고 있습니다. 연구는 주로 표면 일렉트로미오그래피(EMG)와 운동역학 데이터를 활용하여 신체의 근육 조절 방식을 정량적으로 분석합니다.

The cervical spine is forced to move from the lower vertebrae during rear-end collisions. This motion completely differs from normal extension motion and is probably related to the injury mechanism.
Excessive competitive swimming activities might exaggerate lumbar intervertebral disk degeneration, especially in the L5-S1 intervertebral segment.
This study investigated muscle synergy during smash shot in badminton and compared synergies of advanced players (more than 7 years experience) and beginner players (less than 3 years experience). The dominant hand of all players was the right side. Muscle activities were recorded on both sides of the rectus abdominis, external oblique (EO), internal oblique/transversus abdominis (IO/TrA), and erector spinae. Additionally, the right side of the biceps brachii, triceps brachii, flexor carpi radia
The nordic hamstring exercise (NHE) is a dynamic lengthening hamstring exercise that requires trunk and hip muscles activation. Thigh muscles activation, specifically hamstring/quadriceps contractions has been previously examined during NHE. Trunk and hip muscles activity have not been enough studied. The aim of this study was to analyze of hip and trunk muscles activity during NHE. Surface electromyography (EMG) and kinematic data were collected during NHE. Ten healthy men with the age range of
Improving the performance of underwater undulatory swimming (UUS) improves swimming time, so it is important to identify the pattern of muscle coordination in swimmers with fast UUS. This study aimed to identify muscular coordination in the trunk and lower limb during UUS in elite swimmers. Nine swimmers (aged 20 ± 2 years; height, 1.74 ± 0.03 m; weight, 73.0 ± 4.4 kg) participated in this study. Measurements were taken by electromyography of eight muscles: rectus abdominis (RA), internal abdomi
Lumbar injury prevention intervention might be effective to prevent lower back injury in swimmers. Injury risk factors included female and old age; younger female athletes should prevent the development of injuries as they mature.
This is a report of a rare characteristic anomaly of the laminae of the axis. A multiplane reconstruction of the CT images and a stereolithographic model were useful for treatment of this case. Possible causes of this anomaly may be the failure of ossification or fusion of the embryological term.
We detected a flexion motion of the upper or middle cervical spine during direct face impact. In an actual accident, if the cervical spine is forced into similar motion, we speculate that neck injury would occur in this retraction-like curvature of the cervical spine.
