The objective of this study is to figure out the effect of yoga exercise program on the physical self-description of ADHD adolescents, and the subjects are 36 middle school male students who attends middle schools in Jeonlabuk-do, and 18 subjects are categorized as experimental group, and remaining 18 subjects are categorized as control group, and the experimental group participated in 12-week yoga exercise, and the result is as follows. First, pretest of all factors on physical self-description on the control and experimental group showed no statistically meaningful difference, but in post test, all factors showed statistically significant difference(p < .001). Second, experimental group showed positive improvement in pretest of every factor of appearance, health, flexibility, body fat, sports confidence, muscle power, and muscle endurance than control group, so there was statistically meaningful difference(p < .001), and control group showed negative aspect of regular exercise after 12 weeks, so there was statistically meaningful difference(p < .01). These results indicate that yoga exercise is effective program for all sub-factitive physical self-description changes of the Attention- Deficit Hyperactivity Disorder Youths physical self-description.

본 연구는 비만 청소년들에게 태권체조 프로그램과 걷기운동 프로그램을 각각 실시하여 일반적으로 비만 프로그램으로 검증된 걷기운동을 태권체조와 함께 비교·분석하여 태권체조 프로그램의 특성이 비만 청소년의 신체구성, 혈중지질 및 GH→IGF-I axis 수준에 미치는 영향을 규명하고자 하였다. 본 연구의 대상자는 통제집단 10명, 비교집단에서 태권체조집단 10명, 걷기운동집단 10명을 선정하여 12주간 프로그램을 실시하였으며, 자료처리는 집단 상호간의 차이에 대한 실험오차를 줄이기 위해 공분산분석(ANCOVA)을 실시하였으며, 각 집단별 운동기간에 따른 시점별 차이는 대응표본 t-검증을 실시하였다. 모든 통계적 유의수준(α)은 .05로 설정하였다. 본 연구에서 얻은 결과를 요약하여 기술하면 다음과 같다. 1. 신체구성의 변화에서는 집단 간 체중(p<.001), 체지방률(p<.01), BMI(p<.001)에서 유의한 차이가 있는 것으로 나타났다. 집단별 운동기간 전·후에 따른 변화는 태권체조집단의 경우 체중 3.98kg(p<.001), 체지방률 3.18%(p<.001), BMI 1.75(p<.001) 유의한 감소가 나타났으며, 걷기운동집단의 경우도 체중 3.44kg(p<.001), 체지방률 2.28%(p<.001), BMI 1.39(p<.01) 유의한 감소가 나타났다. 통제집단은 특별한 변화가 나타나지 않았다. 2. 혈중지질의 변화에서는 집단 간 HDL-C(p<.05), TG(p<.01)에서 유의한 차이가 있는 것으로 나타났다. 집단별 운동기간 전·후에 따른 변화는 태권체조집단의 경우 TC 9.9mg/dL, LDL-C 10mg/dL(p<.05), TG 25.4mg/dL 감소가 나타났고, HDL-C 2.8mg/dL 증가하였다. 걷기운동집단의 경우 TC 2.82mg/dL, LDL-C 3.4mg/dL(p<.05), TG 62mg/dL 감소가 나타났고, HDL-C 1.4mg/dL 증가하였다. 통제집단은 특별한 변화가 나타나지 않았다. 3. GH→IGF-I axis 수준의 변화에서는 집단 간 GH(p<.05), IGF-I(p<.01)에서 유의한 차이가 있는 것으로 나타났다. 집단별 운동기간 전·후에 따른 변화는 태권체조집단의 경우 GH .690mg/mL, IGF-I 145.10ng/mL(p<.01) 유의하게 증가하였으며, 걷기운동집단의 경우 GH .285mg/mL, IGF-I 84.90ng/mL(p<.001) 유의한 증가가 나타났다. 통제집단은 특별한 변화가 나타나지 않았다. 이상의 결과를 종합해 볼 때, 12주간의 태권체조 프로그램이 비만 청소년의 신체구성, 혈중지질 및 GH→IGF-I axis 수준의 활성화에 매우 긍정적인 영향을 미치는 것으로 결론지을 수 있다. The purpose of this study was to investigate the effects of a 12weeks Taekwondo Aerobic exercise and Walking exercise program on body composition, blood lipids and GH→IGF-I axis in Obese Adolescent. The subjects of this study were 30 obese Adolescent(Taekwondo Aerobic Group n=10, Walking Exercise Group n=10, Control Group n =10). The data was analyzed by ANCOVA and paired sample t-test, and the level of statistical significance was all set at .05. The major results were as follows: 1. The changes of body composition were significant changes on body weight(p<.001), body fat mass(p<.01), BMI(p<.001) among groups. The changes of body composition in the Taekwondo Aerobic Group were decreased after 12 weeks of exercise. That is, body composition such as body weight 3.98kg(p<.001), body fat mass 3.18%(p<.001), BMI 1.75(p<.001) were decreased after 12 weeks. The Walking Exercise Group was decreased body weight 3.44kg(p<.001), fat mass2.28%(p<.001), BMI1.39(p<.01) after 12 weeks, but the Control Group had no differences. 2. The changes of blood lipids were significant changes on HDL-C(p<.05), TG(p<.01) among groups. The changes of blood lipids, TC 9.9mg/dL and LDL-C 10mg/dL(p<.05) and TG 25.4mg/dL, in the Taekwondo Aerobic Group were decreased and HDL-C 2.8mg/dL was increased after 12weeks. The changes of blood lipids, TC 2.82mg/dL and LDL-C 3.4mg/dL(p<.05) and TG 62mg/dL, in the The Walking Exercise Group were decreased and HDL-C 1.4mg/dL was increased after 12weeks. The Control Group had no differences. 3. The changes of GH→IGF-I axis were significant changes on GH(p<.05), IGF-I(p<.01) among groups. The Taekwondo Aerobic Group was increased GH .690mg/mL, IGF-I 145.10ng/mL, and The Walking Exercise Group was increased GH .285mg/mL, IGF-I 84.90ng/mL after 12 weeks. The Control Group had no differences. Consequently, These results suggest that parallelism of regular Taekwondo Aerobic Program has a positive effect on body composition, blood lipids and GH→IGF-I axis activation in Obese Adolescent.

MiDF, Micro Defect Free concrete, is the concrete made for high strength development by minimizing the defects such as micro pore and ITZ. Since MiDF exhibits strength through hydro-thermal synthesis reaction, it is essential to select the optimum C/S mole ratio. In this study, the basic characteristics of MiDF were evaluated by controlling the C/S mole ratio by SF and QP.

In order to investigate of the pulmonary functions after exercise in control group and dance sport group, 10 female athletes from dance sport were tested with 12 female non-athletes. Pulmonary function test of forced vital capacity, forced expiratory volume, and forced expiratory flow were performed using the spiro-analyzer test system. Followings were obtained by tests and analyses; 1. Forced vital capacity(FVC) of resting had significant difference between dance sport of 3.39±0.51ℓ and control of 2.92+0.23/(p<.05), After exercise FVC were higher than resting both in control(3.06±0.23ℓ) and in dance sport(3.87±0.31ℓ, p<.05) respectively. 2. Forced expiratory volume for 1 second(FEVl) of resting showed significant difference between dance sport of 3.07±0.31ℓ and control of 2.40+0.19/ (p<.05). On this, FEV1% also came out difference between dance sport of 90.56+3.74% and control of 82.19±3.88%. After exercise FEV1 had significant difference between dance sport of 3.87±0.31ℓ and control of 2.39±0.20ℓ(p<.05). On this, FEV1% also came out difference between dance sport of 91.99±3.12% and control of 78.10±5.41%. 3. Peak expiratory flow(PEF) of warm-up and after exercise were revealed significant difference between dance sport(6.54±0.83, 7.12±0.98ℓ p<.05) and control(5.17±0.61ℓ, 5.54±0.63ℓ, p<.05) respectively. FEF25% of warm-up and after exercise also came out significant difference between dance sport(5.72+0.57ℓ, 6.08+0.74ℓ, p<05) and control(4.13±0.43ℓ, 4.41 ±0.36ℓ, p<.05) respectively.

The purpose of this study is to describe the effects of caffeine ingestion on the metabolic responses during submaximal exercise. Ten male of long distance runners aged 19-22yrs were sampled for this study. No subjects had any remarkable medical history and none were taking medications. According to the ingestion of dehydrated caffeine(6㎎/㎏), they were classified into two groups ; caffeine group(CA) and placebo group(PA). A randomized, double-blind, and crossover protocol was employed using for both CA and PA. Subjects underwent a submaximal bicycle ergometer. Blood was drawn intravenously prior to 60 minutes, at rest, at 30 minutes, and 45 minutes of exercise, and recovery period. Plasma concentrations of glucose, free fatty acid and lactate were obtained using enzymatic method. The followings were obtained by the tests and analyses ; 1) Blood glucose (BG) after 45 minutes of exercise was significantly decreased in CA group of 79.0±12.4 ㎎/100㎖ compared with PA group of 93.7±10.4 ㎎/100㎎ (p<.05). 2) Free fatty acid(FFA) after 30 minutes of exercise was significantly increased in CA group of 680.7±90.2 μEq/ℓ compared with PA group of 380.9±120.4 μEq/ℓ(p<.05). The recovery of FFA of recovery was significantly different between CA group of 980.8 ±100.3 μEq/ℓand PA group of 610.7±80.6 μEq/ℓ(p<.05). After exercise, FFA was significantly higher in CA group than in PA group (p<.05, p<.01). 3) There was no significant difference in blood lactate between the two. After exercise, BL was higher than resting both CA group(2530±870 μEq/ℓ, p<.05) and PA group(2120±790 μEq/ℓ, p<.05) respectively.
