張仁鉉 대구효성가톨릭대학교 1986 연구논문집 Vol.32 No.1

The aims of this research are; firstly, to give an effective track and field training to women's college students who are majoring in Physical education and Dancing, and to evaluate their ability adequately, secondly, to provide some basic data for the adequate performance of athletic curriculum. The records of 8 track and field events were measured and compared between the students of Physical education and those of Dancing. The subjects were the students who had been given lectures on track and field during 4 years from 1981 to 1984. The following are the results obtained: 1. In 100M and 200M sprints, at physical education were superior in records to those of Dancing. 2. In Long Jump, Shot Put, Discus Throw and Javelin Throw, at p<0.001, the students of Physical education showed the same superiority as that of the above. 3. There were no differences in 100M Hurdle and High Jump. In conclusion, the students of Physical and those of Dancing should be separated for the effective education in track and field.

Figure skating의 과학적인 훈련처방을 위한 자료 제공을 목적으로 대구시내에 거주하는 평균 연령 17세의 여자 Figure skating 선수 10명을 대상으로 단 시간 운동형태인 Compulsory figure, Jump, Spin, Step, 장시간 운동형태인 Forward skating, Crossing, Free skating 등 7가지 운동형태의 운동수행을 통하여 심박수 및 최대산소섭취량, 에너지소비량에 따른 운동강도를 분석한 결과는 다음과 같다.1 최대운동부하검사에서 최대평균심박수는 분당 192.4회, 최대산소섭취량은 53.5㎖·㎏^-1·min^-1으로 나타났다. 무산소성 역치(AT)시점에서의 평균심박수는 171.0회로 88.9%HRmax으로 나타났고 또한 평균산소섭취량은 37.3㎖·㎏^-1·min^-1로 70.1%VO₂max으로 나타났다.2. Free skating의 운동강도는 99.5%HRmax (191.4회)와 85.0%VO₂max (45.45㎖·㎏^-1·min^-1)로 나타났다. Energy cost(EC) 는 98.7%ECmax (16.3㎉·min^(-1))였으며 Free skating, Forward skating, Crossing은 심박수와 산소섭취량에 대한 AT시점은 각각 88.3∼88.8%HRmax, 65.8∼69.4%VO₂max 수준의 운동강도였다.3. Compulsory figure의 운동강도는 심박수에서는 73.8%HRmax (140.1회), 산소섭취량에서는 45.6%VO₂max (26.0 ㎖·㎏^-1)·min^-1), 에너지 소비량은 48.4%ECmax (7.06㎉·mn^-1)로 다른 운동형태 중 가장 낮았다. The aim of this study is to provide the figure skating with the data for the scientific training. Subjects were consisted of 10 members of figure skaters in Taegu city whose average age were 17. The forms of figure skating included the long-duration exercise and short-duration one. Compulsory figure, Jump, Spin, and Step were included in the former, and Forward skating, Crossing and Free skating in the latter.The exercise intensity according to Heart rate(HR), VO₂max and Energy cost(EC) in each skating forms were analyzed, and the results were as follows:1. In the treadmill test, HRmax was 192.4bpm, and VO₂max was 53.49㎖·㎏^-1·min^-1. AT was begun to be seen at 88.9%HRmax and 70.1%VO₂max.2. Free skating showed the highest exercise intensity including 99.5%HRmax, 85.0%VO₂max and 98.8%ECmax.3. In the long-duration exercise, the range of AT was 88.3∼88.8%HRmax and 65.8∼69.4%VO₂ max, and that of energy cost was 93.2∼98.7%ECmax.4. The intensity in the short-duration exercise was considered 78.8∼82.5% HRmax, 48.55∼62.1%VO₂max and 48.4∼66.1%ECmax.

신체활동 집단의 VO_2max 와 %Fat 에 관한 연구 : 여자대학 체육·무용전공자를 중심으로

장인현 대구효성가톨릭대학교 자연과학연구소 1990 基礎科學硏究論集 Vol.4 No.-

The aim of this paper was to measure the level of VO2max and % Fat with active group, and to obtain the basis for curriculum in Physical Education and Dancing. The subjects consisted of 106 college women(76 members of Physical Education and 30 members of Dancing in Hyosung Women's University) who are approximately brisk in their movement. V02max was measured by means of Margaria method. In order to measure the % Fat the skinfold of triceps and subscapular was measured, and then the body density was calculated in terms of the Nagamine method. The % Fat was calculated from the body density by using Brozek's Formular. The results obtained by the above method was as follows ; % Fat was 21.86%. It was nearly the same as that of other college students in the same age and the range of the value was normal. VO2max was 45.59Ml/kg·min. It was higher than that of the other students in the same age. In conclusion, the body composition and aerobic work capacity of the subjects can be thought to be normal. I guess that this is due to the effect of the subjects's continuious physical exercise in daily life.

여자대학생의 최대산소섭취량과 체지방비율에 관한 비교연구 : 운동집단과 비운동집단의 적정 수준

張仁鉉,洪進杓 대구효성가톨릭대학교 자연과학연구소 1988 基礎科學硏究論集 Vol.2 No.-

The aim of this paper was to present the data by investigation and comparing Vo2 max and %Fat between the athletic group and the unathletic group of women students. The former group was consisted of 104 women students from the Dept. of Physical Ed. And Dancing whose physical activities were comparatively active, and the latter group 51 women students from Dept. of Business Ed. whose physical activities were not so active as theformer, in Hyosung women's University. Vo2 max was measured by using Margaria method. Step-up test was performed with 35cm hight of bleacher. The first work load of 15t/min and the second one of 22.5t/min inbetween 5minute's rest carried out for four minutes respectively. After that heart rates were measured with Japanese digital pulsimeter, and Vo2 max predicted from the rates values. As for %Fat, the left triceps skinfold and the right subscapular skinfold were measuredby mm unit, using skinfold caliper(EIYOKEN type). %Fat was estimated from the body density obtained from the above method. The results obtained are following : 1. Vo2 max in the former and the latter groups were 37.5ml/kg·min and 34.0ml/kg.min respectively, both groups retaining proper Vo2 max level in respect with their ages. 2. %Fat in the former and the latter groups were 17.3% and 19.4% respectively, also retaining proper level. 3. In both groups, 13 students(8.4%) had Vo2 max lower than 30ml/kg·min, and the same number of students had %Fat lower than 15%Fat. For these students a proper treatment should be needed.

스포츠 생리학 : 피겨 스케이팅의 운동강도 추정 - 빙상학습 활성화 방안 -

장인현(ChangIn-Hyun),전윤수(JeunYoun-Su),안나영(AhnNa-Young) 한국체육학회 1997 한국체육학회지 Vol.36 No.3

피겨 스케이팅 학습시의 운동강도를 추정하기 위해 초 중 고·성인 연령대로 구성된 초급자 (10세-13세) 10명과 중급자(13세-22세) 10명으로 피험자를 선정하였다. 피험자의 최대 운동강도를 알기 위해 트레드밀로 점증 최대 부하 검사를 실시하였으며 심박수와 산소섭취량을 이용하여 회귀식을 구하였다.피겨 스케이팅 학습시의 피겨 동작인 Compulsory figure, Step, Spin, Jump, Crossing, Forward skating을 실시하는 동안 그때의 심박수를 측정하여 주어진 회귀식을 이용 개인별 산소섭취량을 추정하였고 에너지 소비량도 산출하였다. 이들 추정 값을 이용하여 최대 운동능력에 대한 강도(%)를 비교 분석한 결과 다음과 같은 결론을 얻었다.초급자의 회귀식은 평균 Y=0.332525X - 23.930072 (r² = .92)이고 중급자는 Y=0.398921X - 30.458237 (r² = .94)이었다. 운동강도는 초급자가 39.0 %VO₂max에서 91.5 %VO₂max 사이였고, 평균강도는 61.7%VO₂max 였다. 중급자는 52.5%VO₂max 에서 89.5%V0₂max 사이였고 평균강도는 69.5%VO₂max 였다.이러한 결과를 종합해 볼 때 피험자와 같은 학습자들을 위한 피겨 스케이팅의 운동강도는 최대 산소 섭취량을 기준으로 낮은 강도가 약 50% 이상, 높은 강도가 약 80% 이상 수준임을 알 수 있다. The aim of this research was to provide the degree of exercise intensity for the figure skate learning. In order to measure the exercise intensity in figure skating, we selected 20 subjects in Taegu city whose ages are from 10 to 22. The regression formula was made on the basis of HR and VO₂ which were obtained from the maximal work load test. HRs in each performance in the figure skating such as compulsory figure, step, spin, jump, crossing, and forward skating were measured, and in order to measure VO₂ and energy cost, they were applied to the regression.The results obtained in this research are as followings.1. The regression formula for the beginner`s class and trained class are Y=0.332525X - 23.930072 (r² = .92), and Y=0.398921X - 30.458237 (r² = .94) respectively.2. The exercise intensity for the beginners was between 38.97 %VO₂max and 91.53 %VO₂max, and the average was 61.73 % VO₂max.3. The exercise intensity for the trained was between 52.46 %VO₂max and 89.48 %VO₂max, and the average was 69.54 %VO₂max.From the above data, we can conclude that minimal exercise intensity should be about 50 %VO₂max and the maximal about 80 %VO₂max.

Until now, dimmable fluorescent luminaires has been widely used for dimming systems, and LED is currently attracting attentions as a alternative lamp due to environmental problem issues. LED, one of eco-friendly high efficiency lamp, has advantage that dimming is easy than fluorescent luminaire. But there have been not enough research on technical development and application for LED dimming. Therefore, to analyze luminous quantity of dimmable LED, the illuminance, color temperature, luminance, and current were measured in the whole range of dimming. In the results of this study, the dimmable LED of various types showed a similar trend in the changed luminous quantity by dimming.
