이 연구는 우수 조정 indoor rower 기구를 통한 구간별 동작 비교에 대한 연구이다. 본 연구에서 대상자는 국가대표 스컬종목 선수 4명(여자: 2명, 남자: 2명)이고 키는 180±7.11 cm, 몸무게 78±11.10 kg, 경력 6.75±1,70 yrs, 경기기록 7분 24.99±26.96초이다. 조정 동작을 촬영하기 위해서 Qulisys 사의 Opus3인 적외선 카메라 8대를 사용하였다. 연구결과로 소요시간은 모든 변인에서 2000 m가 가장 짧게 나타났다(p<.05). 관절 가동범위에서는 하지관절인 무릎관절, 엉덩관절에서는 start구간이 다른 구간보다 작은 것으로 나타났다. 그러나 상체관절인 주관절은 start구간이 500 m구간보다 크고 견관절은 500 m와 1000 m구간 보다 크게 나타났다(p<.05). 발목관절각도의 좌우 비대칭지수는 start구간이 1500 m와 2000 m구간에 비해 크게 나타났다(p<.05). 발목관절의 최대 각속도는 start구간이 500 m구간보다 작게 나타났으며, 2000 m구간이 start, 500 m, 1000 m구간보다 크게 나타났다(p<.05). 그리고 주관절 최대각속도는 start구간이 2000 m구간보다 작게 나타났다(p<.05). 이상 살펴본 바와 같이 배를 추진시키기 위해 관절의 가동범위는 start구간에서 하지관절 보다는 상지관절의 가동범위를 증가시켜다. 그리고 거리가 증가할수록 좌우 비대칭적으로 노를 젖기 때문에 거리적인 손실로 경기력에 영향을 줄 것으로 판단된다. The purpose of this study was to investigate the differences in rowing kinematics between every 500 meter using an single scull machine. Four national team sculling rowers(height: 180±7.11 cm, body mass: 78±11.10 kg, career: 6.75±1.70 yrs, personal record: 7min. 24.99±26.96 sec) participated in the test. The findings indicated that the fastest time was found at the finish line(p<.05). The range of motion (ROM) of knee and hip joint appeared to be smaller at the start line compared to other sections while ROM of elbow joint appeared to be greater at the start line compared to 500 meter section (p<.05). In addition, ROM of shoulder joint appeared to be greater at the start line compared to 500 meter and 1000 meter sections (p<.05). Regarding the analysis of asymmetry, greater asymmetric ROM in ankle joint was shown at the start line compared to 1500 m section and finish line (p<.05). The maximum angular velocity of ankle joint appeared to be smaller at the start line compared to 500 meter section while they were greater at the finish line compared to the start line, 500 meter, and 1000 meter sections (p<.05). The maximum angular velocity of elbow joint appeared to be smaller at the start line compared to the finish line (p<.05). Based on the findings, it was concluded that the rowers utilized more upper body compared to the lower body in order to accelerate the boat during first and 500 meter Furthermore, more asymmetric motion of rowers was shown as the distance was increased which may be caused by an increased level of fatigue.

The purpose of this study lies in measuring psychological skills used when golf players are playing golf games or taking exercise, and knowing differences of their skills according to their skill-level and golf career. Sample groups were randomly made as this study's subjects; 67 male pro golfers who participated in 2003 Tailor Made-Adidas Cup-Chungcheong Open golf Championship, 66 semi-pro golfers who participated in 2003 KTF Tour 6th golf Championship, and 69 pro-applicants who participated in 2003 Semi-Pro Test. Golf players' psychological skills were measured with use of Woo Chan Myung(2003)'s 'Golf Players' Psychological Skill Test'. t-test, Pearson Correlation Analysis, one-way ANOVA were carried out on collected copies, Schaffe test was carried out as a post-test. Results obtained are as follows;Differences of psychological skills according to skill levelsAmong the groups of pro golfers, semi-pro golfers, and pro-applicants, the group of pro-applicants showed statistically significant differences in anxiety factor, but the group of semi-pro golfers and the group of pro golfers did not2. Differences of psychological skills according to golf careerThe longer the length of players' golf career was, the more statistically significant differences were shown in anxiety factor and mind-control factor. The group of golfers whose golf career is below 10 years and the group of golfers whose golf career is over 10 years showed statistically significant differences only in anxiety factor.
