중등학교 체육교사의 신체조성 평가

김기학(Ki Hack Kim),문규진(Kyu Jin Moon),김헌경(Hun Kyung Kim) 한국발육발달학회 1994 한국발육발달학회지 Vol.2 No.1

慶尙北道內의 中等學校 體育敎師 159명을 對象으로하여, 體育敎師의 身體組成의 評價方法을 검토한 결과는 다음과 같이 요약할 수 있다. 1. 體脂肪率이 25%이상인 사람, 즉 肥滿으로 判定된 사람은 169명중에서 7명이다. 2. 年齡別 適定水準의 BMI값을 넘는 사람은 33명이며, 이 중에서 體脂肪率이 25%이상인 사람은 5명이며, 肥滿度+20%이상인 사람 32명증, 體脂肪率이 25%이상인 사람은 4명이다. 3. 體脂肪率과 體格指數와의 相關은 BMI r=0.428, RI r=0.385, 肥滿度 r=0.415, 比體重 r=0.429로 낮은 相關을 보이고 있다. 4. 體格指數와 形態測定項目을 이용하여 體脂肪率을 推定하는 式의 精密度는 비교적 낮게 나타나고 있으나, BMI, 上脘三頭筋都 皮下脂肪厚, 扁甲骨下部 皮下脂肪厚를 說明變數로 하는 推定式의 精密度(R=0.580, SEE=2.51%)가 가장 높게 나타났다. 5. 體脂肪率을 이용하여 肥滿을 판정할 경우와, 體格指數를 이용하여 肥滿을 판정할 경우의 일치도가 낮기 때문에, 運動量이 많고 筋肉이 발달한 體育敎師와 같은 特定集團의 身體組成을 평가할 때, 體格指數만을 이용하여 肥滿을 판정하면 妥當性이 낮은 것으로 판단되었다. A simple quick method of assessing quantitatively the fat content of the body would be of greet practical importance. Particularly, anthropometrics indices and skinfold thickness are commonly used measures of adiposity in clinical or field studies. This study was designed to examine the body composition of physical education teacher and to investigate the relationship between percent body fat(%fat) determined by bioelectrical impedance(BI) method and anthropometrics indices or skinfold thickness. The subjects were 159 physical education teacher, 27-60 years of age living in the Kyungpook region. The BI was measured using a tetrapolar bioelectrical impedance method. Body density(Db) was calculated from the formula of Nakadomo et al., and Db was converted to %fat using the formula of Brozek et al. Obesity is classified as %fat greater than 25%, body mass index above 30, and degree of obese above +20%. Other studies suggest there are significant relationships between accepted methods of determining %fat and simple index calculated from weight and stature. However, the correlations between %fat and anthropometrics indices are lower in the present study than other studies. The results of comparison clearly showed that the validity of the anthropometrics indices were found to be unsufficient, thereby indicating the need for a more accurate method of assessing body composition in physical education teacher. Prediction equations were developed using regression analysis. R and standard error of estimate(SEE) values ranged from 0.46 to 0.58 and 2.47 to 2.51%, respectively. The regression analysis indicated that physical index and skinfold thickness were unsignificant predictors of the dependent variables %fat. The accurate assessment of adiposity in a living organism is undoubtedly difficult, and a great deal of data should be accumulated for assessment of body composition in the physical education teacher.

국민학교 8-11세의 남자 1244명, 여자 1144명을 비수도어 따라 비만, 정상, 수척의 3군으로 분류하여 3군간의 형태의 발육곡선과 발육속도곡선, 신체조성의 변화곡선과 변화속도곡선을 비교한 결과는 다음과 같다. 1. 비만군은 남여 모두 정상, 수척군과 비교하여 신장, 체중, 피하지방후, 주위, 신체조성의 간이 유의하계 높게 나타나 형태발육이 우수한 것으로 나타났다. 2. 신장, 체중의 발육곡선은 비만, 정상, 수척군 모두 연형 증가에 따라 거의 직선적으로 증가하는 경향을 보이고 있다. 그러나, 발육속도곡선은, 비만, 정상, 수척군간에 서로 다른 특징적인 경향을 보이고 있다. 3, 피하지방후의 발육곡선은 남자의 경우에는 3군 모두 연령증가에 따른 변화가 나타나지 않고 있지만, 여자는 3군 모두 약간 증가하는 경향을 보이고 있다. 한편, 여자의 발육속도곡선의 특징은 9-10세에 3군 모두 급격하게 감소하는 경향을 보이고 있다. 4. 주위는 남여 3군 모두 연령증가에 따라 약간 증가하는 경향을 보이고 있지만, 발육속도곡선은 3군간에 서로 다른 특징을 보이고 있다. 5. 체지방률의 변화곡선은 남여 3군 모두 연형증가에 따른 변화가 나타나지 않고 있지만, 변화속도곡선의 특징은 남여 비만군 모두 9-10세에 감소, 10-11세에 증가하는 경향을 보이고 있다. 6. 지방의 변화곡선은 남여 모두 비만군의 증가 경향이 정상, 수척군 보다 약간 현저하게 나타나고 있으며, 변화속도곡선은 남자 비만군은 감소하는 경향을, 여자는 증가하는 경향을 보이고 있다. 7. 제지방의 변화곡선은 남여 3군 모두 연형증가에 따라 거의 직선적으로 증가하는 경향을 보이고 있다. 변화속도곡선의 특징은 비만 남자는 9-10세에 증가, 10-11세에 감소하는 경향을, 여자는 증가하는 경향을 보이고 있다. The purpose of this study was to investigate the characteristics of changes on physical growth and body composition. A percent body fat(%fat) was used to determine the changes. Subjects(boys=1244, girls=1144) were elementary school students whose age ranged from 8 to 11 years old. Test items were a height, a body weight, a girth(abdominal and hip), a skinfold thickness(triceps, and subscapular) and a bioelectrical impedance. The body density was calculated by using the equation of Kim et al.(1993) and %fat was determined by the Lohman`s equation(1984). The criterion for obesity was over 20% and 25% %fat in boys and girls, respectively. The criterion for leanness was under 12% and 15% in boys and girls. The growth curves of the height and the body weight in the obese, normal and lean groups showed an increasing tendency for the all subjects with the age increased. The growth curves of skinfold thickness were not significantly different among obese, normal and lean groups. Abdominal girth was slightly increased in all boys and girls with the age increased. However, the growth velocity curve of height, body weight, and skinfold thickness were different between groups. Therefore, it is necessary for a growth velocity curve to understand growth characteristics in obese, normal and lean groups. The results of this study indicated that the change of %fat in the obese, normal, and lean groups were not appeared in boys and girls with the age increased. The findings also revealed that the body fat and fat-free mass were slightly increased with the age increased.

The present study achieved the following conclusion by analyzing of theoretical timing variability and fore variability which are controled in very rapid movement. 1. As common as the speed-accuracy trade-off phenomenon seems to be for movement behavior where spatial accuracy is major goal. 2. The primary determinant of timing accuracy is movement time, with longer movement time generating more timing error. 3. It is produced a kind of inverted-U effect that very rapid and very slow movement having the most spatial accuracy and the moderate - speed movement having the least spatial accuracy. 4. The future research require experimental study on the more complicated action because these are very simple skill.

The purpose of this Study is to find what part of a human body affects physical fitness. For this study: 1. The subjects was arandom election of 100 students in B High School. 2. The correlation coefficient of part of a human body and physical fitness, and the mean, standard deviation of each items were figured out. 3. The items testedare: length of lower limb, length of lower thigh, length of upper thigh, length of upper limb, length of upper arm, length of fore arm, Girth of upper arm, Girth of fore arm, girth of thigh girth of calf, and 100m dash, ball throwing, standing broad Jump, sit up, chinning the bar as physical fitness factors. The following conclusion has been drived from the fore going results through analyses and observations. 1. girth of upper arm, girth of fore arm, girth of thigh, and girth of calf have an effects on 100m dash and ball throwing, but don't have an effects on standing broad jump, chinning the bar and sit up. 2. length of upper limb has an effects on every physical fitness factors except sit up. 3. length of upper arm has only a little effects on 100m dash and chinning the bar, but has a considerable influence on standing broad jump. 4. length of fore arm has an influence on 100m dash, Ball throwing and chinning the bar. 5. length of lower limb has a considerable influence on standing broad jump, chinning the bar, sit up 6. length of lower thigh has an effect on standing broad jump, chinning the bar, and length of upper thigh has a considerable influence on chinning the bar item only. 7. 100m das and Ball throwing are evenly effected all parts of human body, and standing broad jump and chinning the bar chiefly are affected by length of upper and lower limb, and sit-up item is influenced chiefly by the length of lower limb.

自然主義 體育思潮와 現代體育

文圭鎭 釜山敎育大學 1984 부산교육대학 논문집 Vol.20 No.1

J.J. Rousseau advocated "Naturalism" under the slogan of "Everything according to nature" and "Return to nature." His thoughts have offered an opportunity to remedy the evil of modern society, the loss of humanity caused by the development of material civilization. J. Kocke. told "Sound mind in sound body" in 17th century. It has deeply impressed us and given many lessons to us, modern people. The two naturalist emphasized health first of all. People can cope actively with the changing future soclety by keepiny good health. Their educational objects were: first, to make the children's bodies trained strongly, second, to make the chidren have good habits of life, and third, to make them have clear and pure minds. They emphasized recreation particularly. Recreation is the best way to develop and maintain good personality. It is also the best way to make the people free from tension and weariness and give them the opportunity to express themselves. Rousseau insisted that recreation give the balance of life and true education be the training of mind and body through recreation. Modern people have more opportunities for recreation because of the improvement of the standard of living They need good conditions they can enjoy the recreation. So we should define recreation according to the idea of naturalistie physical education and fix it comprehensively as a branch of social physical education.

The aim of this study was to investigate how the simple stimuli-response (1-choice) and the choice stimuli-response (2-choice, 4-choice) make an influence on Reaction Time (RT) of the Athletes. Subjects were 8 Athletes (Archery : 4, Soft tennis : 4). Lab Activities Manual with Software were used as an experimental device. Thirty reaction time trials will be administered. On each trial, four circles will be presented on the computer monitor.The subject task is to depress the appropriate key (DFJK) as quickly as possible when the stimuli is illuminated. The experimental data were analysied by Regression and Paired t-test through SPSS/PC+. The experimental results were as followed. The RT increaces by nearly an equal amount each time the number of alternative is doubled(1 to 2 to 4). The relationship between the choice RT and the Logarithm to the base two of the number of stimulus alternative should be so linear. The RT values of Soft-tennis ball group are shown on the faster on the choice stimuli-response than Archery group(P<.05).
