목적 : 본 연구는 척수손상환자들 중 신체활동 정도가 급격하게 차이 나는 운동 선수군과 비선수군의 일상생활동작과 골밀도를 비교 분석하는데 그 목적이 있다. 방법 : 본 연구를 위해 20명(선수 10명, 비선수 10명)의 SCI 환자가 실험에 참가하였다. 골밀도 측정을 위해 이중에너지 방사선골밀도 측정기(Lunar Prodigy, GE Healthcare. England)를 이용하여 종골부위(calcaneus)의 골밀도를 측정하였다. 척수손상환자의 일상 생활 기능을 측정하기 위해 자조관리(self care), 호흡과 괄약근 조절 (respiration and sphincter management task), 이동(transfer)의 세 영역으로 나누어진 SCIM II(Spinal Cord Injury Measurement II)을 이용하였다. 척수손상환자들 중 운동 선수군과 비운동 선수군의 일상생활 동작과 골밀도를 비교 하기 위해 SPSS 14.0 통계 프로그램의 independent t-test를 이용하여 통계분석을 실시하였고 일상생활 동작과 골밀도의 상관관계는 Pearson correlation을 실시하였다. 유의수준은 ${\alpha}$=.05로 통계처리 하였다. 결과 : 검사 결과 선수군이 비선수군보다 통계적으로 유의하게 큰 SCIM 점수와 T-score를 보여주었다. 결론 : 일상생활동작을 측정하기 위하여 SCIM II(SpinalCordIndependenceMeasureII) 척도를 사용하였는데 선수군이 비선수군에 비해 유의하게 높은 SCIM II 총점을 나타내어 운동을 통한 훈련이 척수손상환자의 기능적 활동을 향상시킬 수 있다고 사료된다. 그리고 골밀도 측정 결과 선수군이 비선수군에 비해 통계적으로 유의하게 높은 골밀도를 나타내었다. 이 역시 강도 높은 훈련이 척수손상환자에게 나타날 수 있는 신체구성을 강화시켜줄 수 있을 것으로 사료된다. 운동을 통한 재활 중에서 그 강도가 높을수록 신체의 구성적, 기능적 측면 뿐 아니라 신경의 가소성 측면에서도 증가를 기대해 볼 수 있을 것으로 판단된다.

The purpose of this study was to investigate the ability to maintain dynamic posturography(EquiTest) in gymnastic, freestyle skier, and figure skater. A total of 32 subjects(22 athletic woman and 10 collegiate woman) were participated in this study. Computerized dynamic posturography(EquiTest) was adopted to test sensory organization and motor control. EquiTest facilitated the quantification of the role of somatosensory, visual and vestibular systems in the maintenance of postural balance and was also pertinent to measure the reaction time to the stimulus to change center of gravity on force platform. As a result were as follow. There was not difference among with exercise group. But there was a significantly difference with between groups. It was suggested that the acrobatic and physical activity developed the function of visual system and the role of the combination of visual and vestibular system in maintaining postural balance to surrounding stimulus, and presented shorter reaction time in automatic postural response.

This study aimed to identify the relationship between perfectionism and motivational climate in competitive athletes and to provide information for improvement of their performance. One hundred ninety-six athletes who trained in Korea National Training Center participated in this study and they were divided into record and man-to-man events. Also they filled in the questionnaire about demographic factors, perfectionism, and motivational climate. Collected data were analyzed by using cross validation and independent t-test for identifying the difference of two events and structural equation model for testing hypotheses and model fit. Perfectionism and motivational climate in man-to-man events were stronger compared to record event. In record event, perfectionism was more influenced by ego involving motivational climate compared to task involving, while in man-to-man event, perfectionism was affected by only ego involving motivational climate. However, these both study models had a bad fit.
