장용수 安東大學 1987 安東大學 論文集 Vol.9 No.1

This survey was carried out under the potential premise that the personality traits of archery players might cause significant effects on the games in which they are playing. To determine a more detailed effects, a diagnostic test was performed on male and temale archery players of the universities and the colleges designated for archery training. The test being used was composed of the two scales: the descriptive and the clinical scale, with nine variables in the first, and five in the second. The result obtained from this survey, which is as follows, will suggest some provisions for planning a better training program in archery. 1. There appeared significant differences in personality between the two sexes. Among the five variables of the clinical scale in male players, anxiety marked the highest followed by paranoid tendency and depression. In female, on the contrary, the nervousness scale was characteristically high, with anxiety and paranoid tendency marking the next. 2. Special consideration should be taken in female training; they showed a serious lack of impulseness, conformity, and emotional stability, as well as they showed 6 or 7 times as high nervousness and anxiety scale as male players.

장용수 安東大學 1988 安東大學 論文集 Vol.10 No.1

The present study is intended to show the potential influence which shooting intervals may have on the record of archery players. For this purpose, six players were chosen and the means and standard deviation of their shooting intervals were measured in the games for selecting the representative players for the 24th Olympic Games. The means and standard deviation were correlated with the records in 30m, 50m, 60m, 70m, and 90m shooting, which are the regular events in the Olympiad. The most ideal pattern of the three intervals, as was show by player LHS, was somewhere near 16.25", 19.08", and 21.75", their standard deviations boing measured as 4.81", 9.08", and 7.92", respectively. In general, the player whose first interval was shorter than the second, which in turn was shorter than third, smarked comparatively good records. Sinilarly, the record appeared worse in the player whose last interval was shorter than the second. In sum, since there has been investigated through this survey a high correlation between the interval and the record, it seems necessary for the betterment of the record to establish an appropriate shooting interval pattern for each player according to his/ner various inner and outer factors.

장용수 安東大學校 安東地域社會開發硏究所 1991 安東開發硏究 Vol.2 No.1

The investigation was performed through the questionnaire, in which a total of 916 respondents were analyzed on their consciousness of socio-physical education. The results can be summarized as follows : (1) The consciousness of their own health is generally affirmative but the female, the aged, and the labor group there should be regular planning in which they can be provided with proper knowledge and activities on socio-physical education. This task can be more activated by means of mass media. (2) It is only the professional workers and the young generation that enjoy the variety of sports, but for the labor group, the aged, and the female group, they cannot afford it due the their limitation of time and financial state. To remedy their disadvantage, an practical and professional exercise program and handy facilities are advisable. (3) The large part of the population respond that they are willing to take part if a suitable program is available. In this aspect we can safely say that the exploration of a suitable sports program would sufficiently motivate their willing participation. (4) Most of the population show a great dissatisfaction with the existing facilities, which can be easily overcome by providing them with proper environment and facilities. (5) The population's desire for the positive support from administration is great. To contribute to the activation of socio-physical education as well as to meet the desire, the government is required to formulate a policy to invest for the national health ; that is, to allow them public places for athletic activities, such as unoccupied places, green belts, hills or riversides in the area.

장용수 安東大學 1994 安東大學 論文集 Vol.16 No.1

운동 경력이 10.5±1.77년에 달하고 듣는쪽이 우측인 대학 축구 선수 8명이 대상으로 등속성 운동 측정 기구를 통해 60˚/sec, 180˚/sec 및 240˚/sec 등속도 운동시 좌우 대퇴 굴신력을 측정하여 분석한 본 연구 결과를 요약하면 다음과 같다. 1) 최대 우력치는 굴근력에 비해 신근력이 큰 것으로 나타났으며, 운동 속도가 증가할수록 감소하는 경향을 나타내었다. 2) Deficit ratio는 전체적으로 정상 범위에 있었으나, 개인별 결과를 볼 때, ±10%의 범위를 벗어나는 사례수가 전체의 44%에 달했다. 3) 신전시 최대 우력에 대한 굴곡시 최대 우력의 비율은 유의차가 발견되지 않았으나 우측값이 높은 경향을 나타내었다. 4) 최대 등속성 우력치를 나타내는 관절 각도는, 굴곡시에는 운동 속도가 빠를수록 커지고 신전시에는 운동 속도가 빠를수록 작아지는 경향이 나타내었다. 5) Average power는 굴곡시보다 신전시 값이 큰 것으로 나타났으며, 운동 속도가 빠를수록 신전시와 굴곡시 모두 증가하는 경향을 나타내었다. 6) Total work는 좌우측간에 유의차는 없었으나 우측이 높은 경향을 나타내었고, 신전과 굴곡간의 비교에서는 신전시 값이 높게 나타났다. 7) Endurance ratio에서는 유의차가 발견되지 않았으며, 굴곡시 우측값 이외에는 모두 60%이상의 정상 범위에 있었다. In order to evaluate the isokinetic strength at knee flexion and extention, 8 soccer player enrolled university soccer team were selected. These all subjects' dominant limb 10.5±1.77 yrs. The results were as follows; 1. Peak torque output at flexion were higher than at extention. As the exercise speed increased, peak torque output was reduced. 2. Deficit ratio was entirely in normal range, but abnormal cases were detected(about to 44%) in the light of each case. 3. In the peak torque ratio of hamstrings to quadriceps(Flexion/Extension), significant difference was not detected between right and left in all exercise speeds, but showed a higher tendency in right than in left. 4. Angle of peak torque at flexion was increased as the exercise speed increased. But at extension, the angle was decreased as the exercise speed increased. 5. Average power at extension was higher than at flexion, and showed increasing tendency in all cases as the exercise speed increased. 6. Total work of right lower limb was higher than that of left lower limb in spite of no significant difference. And the result at extension was higher than at flexion. 7. There was no significant difference in endurance ratio. From the above results, it can be concluded that reinforcement exercise which corrects the unbalance of knee joint function in soccer player is necessary.

洋弓選手의 Release Interval에 關한 調査硏究

장용수 安東大學 1986 安東大學 論文集 Vol.8 No.1

This study is to analyze how Release Interval of Arcery players influences on the record, and then to find out a good Release Interval in archery events such as 90m, 70m, 50m, and 30m, employing three college players participated in the 3rd President Flag Tournament. The results from the survey and analysis of them are as follows; 1. The average (X) of H. J. S., pre-national representative player, in Release Interval is 14.16˝ (Fa), 42.58˝ (Sa), 40˝ (Ta), and the standard destination (S. D) is 12. 75˝ (Fa), 13.35˝ (Sa), 12.42˝ (Ta). These records make us believe that he did the b2st Release Interval among other players. 2. But we don't believe H. J. S. to have done a good Release Interval in the event of 50m, as his records are X (43. 75˝) in the first arrow, X (54˝) in the second arrow, and X (32. 81˝) in the third arrow, as though he marked better record among them. The reason that he did not do better Release Interval is due to his heavy burden on R.I. in T.A. 3. Though there are differences in players' physiological, psychological conditions, the good Release Interval, according to the results surveyed and analyzed by this study, is as follows; Fa (40˝), Sa (35˝), Ta (45˝) in short-distance events such as 30m, 50m, and Fa (35˝), Sa (35˝), Ta (50˝) in long-distance events such as 70m and 90m.

The purpose of this study is to understand correctly the personality of the badminton players in boys' high school and to find out good players and train them effectively by developing their specific personality, because personality is a psychological condition for good players. In order to advance the method of training players and obtain fundamental data through understanding properly the character and personality of each player, the survery covering 50 high school badminton players was conducted in three areas from December, 1983 to August, 1984. The findings are such as: 1. When game-history differs; Sociability is highest in the group which has more game-history, while general activity is highest in the one with less history. peculiarly, the impulsiveness placed eighth in the more game-history group is shown second in the less history group. 2. When the role differs; Emotional stability is highest in the regular player group, while sociability is highest in the substitute player group. It is peculiar that dominance placed second in the regular player group is shown at the bottom in the substitute player one. 3. When the training-place differs; Sociability is highest in the group training out of school, while emotional stability is highest in the one training in school. It is peculiar that impulsiveness is shown at the bottom in both groups.
