이 연구의 목적은 8주간의 코어 훈련이 스키선수의 동적자세조절, 하체 손상 및 고유수용성 관절위치감각에 미치는 영향을 보고자 하였다. 이 연구에 참여한 대상자는 스키선수 20명으로 무작위로 코어 운동군 10명과 통제군 10명으로 분류하였다. 코어 훈련프로그램은 벤치, 사이드웨이 벤치, 프랜크, 사이드 브리지 및 서파인 브리지로 구성하였고, 8주간 주 3회 실시하였다. 연구 결과 동적자세조절 검사는 좌·우측 후방안쪽 뻗기에서 유의한 효과가 있었고, 하체 손상 준거 검사는 좌·우측 종합점수에서 통계적으로 유의한 효과가 있었다. 또한 고유수용성 관절위치감각은 왼발 15°과 왼발 45°에서 유의한 감소가 있었다. 결론적으로 8주간의 코어 훈련은 스키선수의 동적자세조절 능력, 하체 손상 감소 및 관절위치감각을 향상시키는 것으로 나타났다.

본 연구는 필라테스 동작 시 폼롤러의 적용과 움직임에 따른 몸통과 하지의 근활성도 차이를 알아보는 것이 목적이다. 피험자로 남자 8명을 선정하여 필라테스 네발자세, 교각자세, 코어컨트롤 동작을 매트위에서 정적동작, 폼롤러 위에서 정적동작, 폼롤러 위에서 동적동작으로 무선배정하여 1주 간격으로 수행하였다. 각 동작의 수행 시 척추세움근, 배곧은근, 배바깥빗근, 중간볼기근, 넙다리두갈래근과 넙다리곧은근의 근활성도를 측정하여 일원분산분석으로 분석하였다. 유의수준은 ${\alpha}=.05$로 설정하였다. 첫째, 네발기기 동작에서 폼롤러 동적동작에서는 배곧은근, 배바깥빗근, 중간볼기근, 넙다리두갈래근의 근활성도가 높게 나타났으며(p<.001)(p<.05), 폼롤러 정적동작에서는 넙다리곧은근의 근활성도가 높게 나타났다(p<.001). 둘째, 교각자세 동작에서 폼롤러 동적동작에서는 넙다리두갈래근의 근활성도가 높게 나타났다(p<.001). 셋째, 코어컨트롤 동작에서 폼롤러 동적 동작에서는 배곧은근, 척추세움근, 중간볼기근의 근활성도가 높게 나타났으며(p<.001)(p<.01), 정적 동작에서는 배바깥빗근의 근활성도가 높게 나타났다(p<.05). 필라테스 운동시 근활성도를 고려하여 방법과 난이도를 적용하면 더욱더 효과적일 것이라 사료된다.

When women are removed with their matrix which is a emotionally significant organ of symbol in psychologically adapting themselves to mother and woman, that is threatened and injured with woman role decisively. This study tried to find the efficient nursing intervention method to maintain and promote their health, to cope with health problem, and to inquire into the loss experience of women with hysterectomy by using the phenomenological method. The analysis of the data was made through the phenomenological analytic method suggested by Giorgi. The result of the study was as follows : The factors which have influence on the loss experience of the subjects are an offer of information, support system, age, occupation, economic situation, family history, character, season, the existence of ovary and religion. The loss experience of matrix was expressed in lingual, reactions to the loss of function, sex, body change and husband, in behavioral behaviors in emotion and body. The loss of matrix of the subjects was relived by religion. perineorrhapy, exercise, reading, watching video and diet. The subjects each showed ways of reaction of fatalism, giving-up, coping on the loss experience of matrix. In conclusion, since we ascertained that the nursing in the process of recovery decide the quality of life. though women with hysterectomy undergo various loss experience and adapt to it in the end, it is necessary to give them enough information and educate husband, having on important effect on the loss experience, to be a good supporter, And technically skilled nurses of consultant are thought to be able to contrive better qualitative life of women with hysterectomy as an important bridge between the subjects and their required information, since the nurses have their well-formed position of relationship of confidence through continuous contact with patients and their family.

Purpose: This study identified the co-activation of quadriceps and hamstring muscles during hamstring strengthening exercises in healthy adults. Methods: Twenty-one participants were required for the present study design to achieve 80% power, 0.8 effect size (η2), and an alpha level of 0.05. Thus, this study recruited 21 healthy adults. All participants performed Nordic exercises, bridge exercises, and one-leg deadlifts randomly. The activity of the rectus femoris, vastus medialis (VM), vastus lateralis (VL), biceps femoris (BF), and semitendinosus (SM) were measured. In addition, the ratios of VM/VL and hamstring/quadriceps (HQ) were measured during the three hamstring strengthening exercises using electromyography. One-way ANOVA was used to compare the co-activation of quadriceps and hamstring muscles in the three exercises. Results: The activity of VM and VL during the performance of one-leg deadlifts was significantly higher than the other two exercises. The BF had significantly higher activity during the Nordic exercises compared to the other two exercises. In addition, the SM activation was significantly greater during Nordic exercises than one-leg deadlifts. Additionally, there was significant difference in HQ ratio among hamstring strengthening exercises. In specific, the one-leg deadlifts yielded a significantly lower HQ ratio. Conclusion: This study revealed that one-leg deadlifts are effective in rehabilitation for anterior cruciate ligament injury. In addition, Nordic exercises can be recommended to facilitate hamstring muscle activation.
