근래에 들어, 웨어러블 기기의 발전으로 사람의 움직임에 대한 측정이 손쉬워 지면서, 워킹, 러닝, 사이클링 등의 인간의 신체 활동 상태를 감지하여 더 효율적인 운동을 할 수 있도록 정보를 획득, 제공하려는 연구가 계속되고 있다. 본 연구에서는 웨어러블 기기중 하나인 스마트 인솔을 통해서 수집되는 가속도 정보와 압력 정보를 사용하여 운동시에 사람의 운동 자세를 감지하고 측정하는 시스템을 구현하였다. 사람이 헬스센터에서 수행하는 각각의 자세는 운동의 특성에 따라 시계열 신호의 표현 패턴이 다르게 나타나며 이 패턴을 통한 정확한 자세의 감지를 위해서 본 연구에서는 다양한 신호처리 알고리즘을 사용하였으며 이 경우 더 정확한 자세를 측정할 수 있음을 알 수 있었다. 따라서 본 연구에서는 정확한 자세의 감지를 위해 운동의 특징에 따라 알고리즘을 선택하여 시계열 정보를 처리 분석 하는 시스템을 제안하였으며 이를 통해 보다 정확하게 사람의 신체활동을 분석할 수 있었다.

본 논문에서는 신체 영상 인식 기술을 이용한 운동 자세 교정 시스템을 제안하고 개발하였다. 구글에서 제공하는 미디어파이프 포즈(MediaPipe Pose) 오픈소스를 사용하여 웹캠으로 사용자의 운동 동작을 실시간으로 인식하여, 인식된 신체 구조의 33개의 관절 위치로 Pose Landmark를 사용하여 사용자의 운동 자세에 대한 횟수 카운트, 운동 동작의 정확도 측정을 할 수 있게 하여 혼자 운동하거나 처음 운동하는 사람들에게 운동의 접근성을 높이고, 올바른 자세로 운동을 하도록 유도할 수 있다.

본 연구는 전방머리자세 대학생을 대상으로 목뼈안정화운동이 머리뼈척추각, 깊은목굽힘근 지구력 및 뒤통수밑근 근긴장도의 변화를 알아보고자 하였다. 이 연구 결과 CSEG에서 CVA, DNFET에서 유의하게 증가하였으며 뒤통수근 근긴장도에서는 경직도에서만 유의하게 감소하였다. 목뼈 안정화운동은 목뼈의 중립자세를 유지하면서 깊은목 굽힘근 활성화되고 근지구력이 향상되었으며, 턱을 당기는 동작으로 튀통수근의 경직이 감소한 것으로 생각된다. 또한 지구력 증가시키고 근 긴장도에 감소는 통증을 조절함에 있어서도 도움이 될 것이다. 따라서 목뼈안정화운동은 깊은목굽힘근과 뒤통수근의 개선을 위한 중재방법임을 확인할 수 있었으며, 전방머리자세 예방하기 위해 필요할 것으로 생각된다.

In this research, we developed an efficient real-time human exercise pose estimation system using multiple Kinects. The main objective of this system is to measure and recognize the user's posture (such as knee curl or lunge) more accurately by employing Kinects on the front and the sides. Especially it is designed as an extensible and modular method which enables to support various additional postures in the future. This system is configured as multiple clients and the Unity3D server. The client processes Kinect skeleton data and send to the server. The server performs the multiple-Kinect calibration process and then applies the pose estimation algorithm based on the Kinect-based posture recognition model using feature extractions and the weighted averaging of feature values for different Kinects. This paper presents the design and implementation of the human exercise pose estimation system using multiple Kinects and also describes how to build and execute an interactive Unity3D exergame.

This study was to find out the effect of cervical and thoracic stretching and strengthening exercise program on forward head posture. 32 adults had forward head posture were selected as the subjects for the study. The training program of the exercise group(n=16) consist of postural education with exercise program, subjects in the control group(n=16) participated in a postural education only. Postural measurements of Craniovertebral Angle(CVA) and Cranial Rotation Angle(CRA) were obtained from the using x-ray and PACS(Picture Archiving and Communications System) ${\pi}view^{TM}$. The results were compared with change of CVA and CRA exercise group were significant(p<.05) compared to the control group. However CRA of contol group was significant(P<.05). Also, there were no significant difference(p>.05) between groups on any pre-test measure. however there were significant difference(p<.05) between groups on CVA and CRA post-test measure. This study showed that cervical and thoracic stretching and strengthening exercise program can improve spinal posture alignment for decreasing forward head posture in subjects. These results can be fundamental data for further development of exercise program in interventions of postural improvement.

The purpose of this study was to analyze kinematic variables of a Mae-ukemi (forward breakfall :MU) in Judo through 3-D image analysis with five Judoka with over 2 years' career (2nd dan, 3rd dan). The kinematic variables include posture, and distance variables; the mean values and the standard deviations for each variable were obtained to analyze kinematic variables of a MU in Judo. From the data analysis and discussion, the following conclusions were drawn : 1) Posture variables : The angles of wrists during right before Mae-ukemi (RBU) were extended from the just MU position(MUP) and flexed from in the right after MU(RAU), and there was a difference in the displacement between the angles of the right and left wrists. The angles of elbows were flexed in the ready position from in the RAU. The angles of ankles were flexed from the ready position to that down position, extended from the down position to that transition, and flexed from the transition positiont to that RAU. 2) Distance variables : The distance height between the mat and shoulders in the RBU(32.2cm) to in the MUP(18.3cm) and in the RAU(20.5cm). during that height between the mat and hips in the RBU(48.0cm) to in the MUP(23.4cm), and in the RAU(30.6cm).

In order to manage the correct posture in daily life, it is necessary to evaluate the objective posture and appropriate prescription and management. The posture evaluation program is widely used as a method to evaluate posture relatively easily and safely. However, the existing posture evaluation program is evaluated by utilizing the position of the skeletal system, but lacks feedback on the result of the evaluation because the muscle information causing the posture is lacking and the efficiency of the program is decreased. Therefore, we will improve the existing posture evaluation program and design the system that helps the correct posture management by the appropriate exercise prescription based on the feedback that the server measures and stores the evaluation result through the SOAP message.

Ab Image Processing can be applied to the various fields nowadays. The healthcare, which people may have interest, is one of those fields. The healthcare program which fitness equipments are used requires the correct posture of body. However, people usually does exercise by oneself with various reasons such as cost to hiring personal trainer. In this case, the effectiveness of training should not be guaranteed. Moreover, reverse effect may be produced. This paper is an implementing a correcting posture program by using image processing techniques, which people can use exercise training by oneself. It is expected that people can have a personal trainer who coaches the correct postur through this program.
