The purpose of this study was to investigate the effect of combined exercise on injury risk factors of lower extremity during landing. Ten sports talented athletes participated in this study. Sports talented athletes participated in a combined exercise (sports talented exercise, coordination) for 16 weeks. A three-dimensional motion analysis was performed using eight infrared cameras (sampling rate of 100 Hz), one force plate, and electromyography system (sampling rate of 1000 Hz) during landing. Kinetic, and kinematics analysis including average impulsive force, angle of lower extremity, vertical stiffness, onset of muscle activation were calculated by Matlab2009a software. Paired t-test was performed at alpha=.05. The average impulsive force in landing phase was not statistically significant (t=-.748, p=.474). The hip joint angle was more decreased in post test compared to pre test (E1: t=2.682, p=.025, E2: t=5.609, p=.000, E3: t=2.538, p=.032). The knee joint (E1: t=-.343, p=.739, E2: t=1.319, p=.220, E3: t=.589, p=.570) and ankle joint (E1: t=.081, p=.937, E2: t=.784, p=.453, E3: t=.392, p=.704) angle were tended to decrease after combined exercise. The vertical stiffness was tended to decrease after combined exercise (t=1.972, p=.080). Onset of quadriceps femoris (t=.698, p=.503) and medial gastocnemius (t=1.858, p=.096) were tended to be faster than biceps femoris (t=-.333, p=.747) after combined exercise. Although thses findings were not statistically significant except on a hip joint angle, risk factors of lower extremity such as joint angle, vertical stiffness and onset of quadriceps femoris, medial gastrocnemius were positively changed after the combined exercise but an additional training for improved onset of biceps femoris would be required in the future.

이 연구는 스포츠에서의 공정성과 권력이 어떻게 형성되고 변화하였는지에 대한 역사적 고찰을 통해서 스포츠에서 공정성에 위배되는 도핑과 승부조작에 대한 문제점들을 인간 욕망의 산물인 권력과의 관계에 대하여 탐구하였다. 첫째, 도핑과 권력의 탐구이다. 도핑의 역사는 스포츠의 역사처럼 오래전부터 존재하였다. 선수들의 약물복용은 자의든 타의든 간에 권력과의 관계를 형성하였는데, 그 중 승리에 따른 부와 명예 그리고 기득권에 대한 유혹과 갈망은 개인, 사회, 국가에 이르기까지 다양하고 폭넓게 자행되었다. 특히 힘의 표현이 냉전시대에서 스포츠에 투영되어 잘 반영되었으며, 이 당시의 잘못된 사고와 관행들이 아직도 도핑과 반도핑의 관계에 대한 본질을 흐리게 하고 있다. 둘째, 승부조작과 권력의 탐구이다. 승부조작 또한 도핑처럼 스포츠의 역사에서 항상 존재해왔다. 스포츠와 공정성의 관계에서 승부조작은 인위적인 결과를 결정하는 것으로 끝나는 것이 아니라 스포츠 도박이나 다른 범죄로 연결되어 문제가 되며, 이는 다시 스포츠로 영향을 미쳐 악순환의 연속이 되게 한다. 이러한 승부조작의 이유에는 권력의 요소인 자본의 형성과 이익을 위한다는 명확한 원인이 형성되어 있어 공정한 스포츠를 더욱 위협하고 있다. 이처럼 스포츠의 공정성과 권력의 관계에서 도핑과 승부조작은 역사적으로 매우 의미가 있으며, 더 많은 연구와 논의가 필요하다. 스포츠의 물질적 가치에 매몰되어 도핑과 승부조작이 아무렇지 않게 용인하거나 묵인되면서 권력의 요소들에 의해서 스포츠 파이만을 키우기만 한다면 마냥 스포츠의 미래가 밝다고만 장담할 수 없다.

This paper is concerned with the numerical investigation of the transfer characteristics of the landing impact force exerted on court sport shoes to the sport surface condition. The reaction force occurred by the impact between court sport shoes and sport surface is absorbed by shoes to some extent, but the remaining impact force is to transfer the human body from the sole of a foot. We consider four surface conditions, asphalt, urethane, clay and wood court surfaces. For the dynamic response analysis, we construct a coupled leg-shoes FEM model and create the multi-layered composite surface model. The numerical simulations are performed by an explicit nonlinear finite element method. Through the numerical experiments, we examine the transfer characteristics of the landing impact force to the surface condition.

A commitment to physical activity is necessary for personal health, and is a primary goal of physical activity practitioners. Effective practitioners rely on theory and research as a guide to best practices. Thus, sound theory, which is both practical and parsimonious, is a key to effective practice. The purpose of this paper is to review the literature in search of such a theory - one that applies to and explains commitment to physical activity in the form of sport and exercise for youths and adults. The Sport Commitment Model has been commonly used to study commitment to sport and has more recently been applied to the exercise context. In this paper, research using the Sport Commitment Model is reviewed relative to its utility in both the sport and exercise contexts. Through this process, the relevance of the Investment Model for study of physical activity commitment emerged, and a more parsimonious framework for studying of commitment to physical activity is suggested. Lastly, links between the models of commitment and individuals' participation motives in physical activity are suggested and practical implications forwarded.

The purpose of this study was to review of animal-assisted therapy. Method: Animal-assisted therapies (AATs) in domestic and international studies (68 cases) were analyzed by searching databases, KERIS & KISS, and the Pub MED(NCBI). Result: In AATs, a few animals were used for the various disease or disorder. Dog centered therapies were most common.. AATs were used in the various disorder and disease. For the psychological effect, majority of the outcome variables were depression and anxiety. For the physical effect, the most outcome variables were blood pressure, heart rate, and stress hormone. However, These results show that AATs were confined to specific areas such as sensation-centered therapies. Conclusion: AATs had positive effects both in physical and psychological factors even if the study areas have not been applied to the various condition. The further research is needed to identify scientific grounds for the effects of the interventions through various therapies.

본 연구는 스포츠 경기의 특성에 따른 스포츠 감정 유형을 분석하였다. 이를 위해 2018년 아시안게임 중, 대한민국 대표팀이 출전한 축구 7경기, 야구 6경기를 선정한 후, 이에 대한 소셜 네트워크 서비스 상 기사와 그 댓글을 조사대상으로 선정하였다. Python을 이용하여 수집된 댓글은 전문가 회의를 통해 해당 감정을 분석하였다. 스포츠 경기의 승패, 상대 팀의 수준 및 대한민국 대표팀의 경기력에 따른 스포츠 감정을 분석한 결과, 첫째, 승패와 상대 팀 수준은 특정한 유형의 스포츠 감정을 형성한다고 보기 어려웠다. 둘째, 스포츠 경기의 경기력은 좋다는 평가를 받을 경우 만족, 열광, 기쁨 등의 긍정적 감정을, 나쁘다는 평가를 받을 경우 실망, 분노, 창피의 부정적 감정을 형성하였다. 셋째, 스포츠 경기와 연관된 사회·문화적 배경이나 해당 경기의 특정한 사건 또한 스포츠 감정의 유형에 영향을 미쳤다. 추후, 본 연구에서 다루지 못한 다양한 스포츠 경기의 특성을 추가하여 보다 많은 스포츠 경기를 대상으로 분석하는 연구가 필요할 것이다.
