Characteristics and Comparison of Trunk Motion of Elderly Women Experienced Fall
( Kim Kwe-wan ),( Jeon Kyoung-kyu ) 인천대학교 스포츠과학연구소 2016 스포츠科學硏究誌 Vol.29 No.0
This study examined the rotation capacity of trunk segment when the trunk moves as a person walks. For this study, 12 elderly women, 6 of whom experienced fall while walking and 6 of whom didn’t experience fall in the last 1 year were examined. In addition, this study examined differences in the maximum range of trunk motion and the characteristics of regularity of motion pattern according to the experience or no experience of fall. Sono-Sens, a spine structure analysis device, was used to measure various variables including maximum range of motion and regularity index of trunk, median sagittal and frontal bending index and amplitude, median torsion index and amplitude, and left and right symmetry. And the following results were obtained. There was no significant difference in body composition of elderly women according to the experience of fall. As for maximum range of motion, there was statistically significant difference in maximum bending of lumbar spine (p<.048) and twisting or left cervical spine (p<.047) according to the experience of fall. There was no significant difference in regularity index of trunk motion change according to the experience of fall. There was no significant difference in median sagittal bending index and range of motion according to the experience of fall. There was no significant difference in median frontal bending index and range of motion according to the experience of fall. As for the median transverse torsion index and range of motion, there was significant difference only in the twisting of thoracic spine according to the experience of fall. There was no significant change in the ratio of left and right symmetry according to the experience of fall.

양궁 컴파운드와 리커브 종목의 슈팅 시 지면반력 차이 변화
이선영 ( Lee Sun-young ),김규완 ( Kim Kwe-wan ),전경규 ( Jeon Kyoung-kyu ) 인천대학교 스포츠과학연구소 2015 스포츠科學硏究誌 Vol.28 No.0
이 연구에서는 양궁 컴파운드 종목과 리커브 종목의 슈팅 시 지면반력 변화를 규명하고자 하였다. 이를 위해 컴파운드 종목선수 5명과 리커브 종목선수 9명 총 14명을 대상으로 실제 양궁경기가 이루어지는 장소의 70m 거리에서 4엔드 총 12발을 지면반력기 위에서 슈팅을 실시하여 얻어진 득점 중 고득점과 저득점으로 구분하여 전후 · 좌우 · 수직 지면반력의 변화를 통해 안정성 변화를 측정하여 나타난 결론은 다음과 같다. 리커브 종목과 컴파운드 종목의 엔드별 기록분포에서 리커브 종목보다 컴파운드 종목의 점수분포가 높게 나타났다. 슈팅 시 고득점과 저득점으로 구분하여 나타난 전후 지면반력은 모든 시점에서 유의한 차이가 나타나지 않았다. 또한 좌우 지면반력의 안정성 변화는 고득점의 모든 시점과 저득점 우측발의 팔로스로우와 좌측발의 릴리즈와 팔로스로우에서는 유의한 차이가 나타나지 않았다. 그리고 저득점에서는 우측발의 앵커링과 릴리즈과 좌측발의 앵커링에서는 유의한 차이가 나타났다. 수직 지면반력의 안정성 변화는 모든 시점에서 유의한 차이가 나타나지 않았다. The purpose of this study was to investigate the changes of changes of ground reaction force on shooting between compound and recurve bow of archery. In order to the purpose, total 14 players which were composed of 9 players in recurve bow of archery and 5 players in compound bow of archery participated in this study and total 12 shots of 4 ends at the 70-meter-distance in the place, which held actual archery competitions, were measured the changes of stability through changes of before and after, left and right, and vertical ground reaction force by dividing scores, which were got by shooting on the ground reaction force machine into high scores and low scores. The results through this are as follows: The score distribution of compound bow of archery was higher than the recurve bow of archery in the record distribution per end between recurve and compound bow of archery. As for the before & after ground reaction force which was appeared by dividing into higher scores and lower scores on shooting between recurve bow of archery and compound bow of archery. As for the stability changes of left & right ground reaction force appeared by dividing into higher scores and lower scores on shooting of recurve bow of archery and compound bow of archery. And it had significant difference in anchor ring and release of right foot and anchoring of left foot with lower scores. As for the stability changes of vertical ground reaction force appeared by dividing into higher scores and lower scores on shooting between recurve bow of archery and compound bow of archery.
