This study aims to find out the effect of ingestion of 3 mg·kg^-1 caffeine on fluid-electrolyte balance and Tty change during exercise under heat environment of 30~32℃ (40-50% humidity). Five trained males who routinely trained for approximately 60 min·d^-1, 3-6 d·wk^-1 (age; 28.20±3.56yrs, height; 174.56±5.46 cm, body mass; 76.13±9.02 kg, body fat(%); 14.24±3.99, VO₂max; 54.00±4.30 mL·kg^-1·min^-1, exercise career; 4.20±1.95yrs) performed 40min of treadmill running in heat chamber. The study was a double-blind, randomized, crossover design. Body mass change following exercise was higher for the PLAC (Placebo) and CAFF (Caffeine) in comparison to the CON (Control), there was no significant difference between the CAFF, PLAC, CON (p= .997). The U_sg not significant differences (p= .731) and Osm_urine not significant differences between the CAFF, PLAC, CON (p= .901). There also were not significant between the CAFF, PLAC, CON for [Na⁺]_urine and [K⁺]_urine (p= .928, p= .469). In the case of Tty, although the increase rate of Tty was the highest for the CAFF on exercise early, exercise the second half in comparison to the CON and PLAC, there was not significant interaction effect between the CAFF, PLAC, and CON of Tty (p= .067), In conclusion, it was confirmed that the 3 mg·kg^-1 caffeine ingestion prior to exercising in heat environment does not impart negative effect on body fluid, electrolyte balance and changes in Tty.

고강도운동의 지속시간이 백혈구 조성과 T-림프구 활성 보조인자로서의 $CD4^+$와 $CD8^+$수준의 변화 그리고 림프수의 세포사에 미치는 영향을 조사하기 위해 쥐실험을 하였다. 고강도 운동을 매일 20, 60, 그리고 120분 동안 8주간 실시하였다. 혈액내의 총 백혈구 수는 20분간 운동을 했을 때 상승하였고 이것은 다시 120분 까지 대조군의 수준 이하로 감소하였다. 림프구의 수준변화 패턴 역시 운동시간의 영향을 받았으며 그 변화 정도는 총 백혈구의 그것과 유사하였다. 고강도운동을 실시한 쥐의 혈액 내 $CD4^+$와 $CD8^+$의 수준은 운동시간이 120분간 지속될 때까지 변화가 없었기 때문에 T-림프구의 활성에는 영향을 주지 않는 것으로 보인다. 거의 모든 초기단계 및 후기 단계의 림프구의 세포자멸사는 운동시간에 영향을 받지 않았으나 120분간 운동한 그룹에서 후기단계의 림프구 자멸사 수준이 증가되는 것으로 보아 이때 세포노화의 촉진이 일어났으리라 사료된다. 운동시간이 길어질수록 림프구의 괴사 수준이 증가되는 것을 확인 하였고 이에 따라 고강도운동에 의한 림프구 손상과 면역력 저하의 가능성이 예상된다. 본 연구에서 장시간 동안의 고강도 운동은 림프구의 염증관련 기능과 세포 수에 있어서의 손상 등을 일으켜 면역력의 저하를 초래할 수 있다고 보며 따라서 적어도 본 연구조건에 한해서 20분 이상의 고강도운동은 건강유지 차원에서 바람직하지 않다고 판단된다.

The multiple acupuncture techniques have been used to relieve the pain of lateral ankle sprain. Recently, early functional rehabilitation is emphasized in rehabilitative concepts using active ROM, facilitated proprioception, alphabet exercise and so forth. Similarly, in oriental rehabilition medicine, traditional movement technique called "Dong-Ki" has been used to relieve pain of ankle sprain. So we used "Dong-Ki" technique with SSP(silver spike point) electrotherapy transformed from alphabet exercise and evaluated the effects in method of randomized controlled trials. Methods : 27 outpatients with lateral ankle sprains were randomized into two groups : 15 samples and 12 controls. Sample group was treated with "Dong-Ki" technique(writing his name with foot) with SSP electrotherapy to relieve pain during additionally. "Dong-KI". Outcomes were measured by 10cm VAS and ankle circumference(cm). Results : In terms of VAS, Sample group had inclination of pain relieving but not significantly meaningful. In terms of ankle circumference measurement, Sample group showed significantly improved.

Purpose: The purpose of this study was to identify the trends regarding diet and exercise intervention studies for Korean obese children between 2010 and 2017. Methods: This study was synthesized and reviewed systematically by meta-analysis. In addition, a total of thirty nine studies were investigated. The random effect model was used for meta-analysis. Results: Most studies used single interventions and that their theoretical frameworks still required improvement. In addition, on-line education programs still need to increase their number over that of off-line ones. Regarding the dependent variables for understandings the influences obesity may have on Korean children, most studies took advantage of biological indicators. In terms of the effects of obesity management programs, multiple interventions have gained a competitive edge over single ones for Korean obese children's diet and exercise. In a similar vein, healthy eating habits and adequate physical activities would have more positive effects on Korean children' obesity management programs. Conclusion: Further various studies will be needed for the early detection and prevention of obese children through varied interventions and qualitative improvement of studies.

Young adults are likely to start a new life style which may cause weight gain or obesity since leaving their parents for higher education or university. Whilst young people are slim in general, it is common to see them trying to manage their weight. Few studies have been carried out in Korea to support those changes in lifestyle that can result in weight gain in early adulthood. This study aims to identify prevalence of dieting as well as factors inducing weight gain among university students under unrestricted living conditions. A total of 99 university students were enrolled and asked to complete a questionnaire over a 3-day study period from June to September, 2008. T-test and $X^2$-test were applied to compare each behavior between weight gainers and maintainers. Logistic regression was also used for further analysis. Half of the participants used 'eat less' and 'exercise' as a way of dieting, and weight gainers tried to control their weight significantly more than weight maintainers. Most participants were engaged in very little exercise and were more likely to watch TV and use a computer. The time of lunch was proven as the only factor to predict weight change in the participants. As a result of this study, an intervention to promote exercise with friends or as a group is required to makeup for the lack of exercise among young adults. Further studies are also necessary to investigate how each meal time a day relates to the amount of food eaten. (Korean J Community Nutrition 14(4) : $374{\sim}382$, 2009)

The purpose of this study was to test the microcurrent electrical neuromuscular stimulation on muscle soreness, serum creatine kinase levels and force deficits evident following a high-intensity eccentric exercise bout. 10 volunteer male subjects were randomly assigned to a treatment group or to a control group. Exercise consisted of high-intensity eccentric contractions of the elbow flexors. Resistance was reduced as subjects fatigued, until they reached exhaustion. Muscle soreness rating was determined using a visual analog scale. Serum creatine kinase levels were analyzed using a blood sample. Force deficits were determined by measures of maximal voluntary isometric contraction at $90^{\circ}$ of elbow flexion on a Orthotron II dynamometer. Muscle soreness rating, serum creatine kinase levels and maximal voluntary isometric contraction were determined at the before exercise and again at 24 and 48 hours postexericse. Treatments were applied immediately following exercise. The control group subjects rested following their exercise bout. Statistical analysis showed significant increases in muscle soreness rating and significant decreases in maximal voluntary isometric contraction when the before exercise was compared with 24 and 48 hour measures(p<0.01). No significant effects were observed between groups in muscle soreness rating and maximal voluntary isometric contraction(p>0.05). Highly significants differences in serum creatine kinase levels were found using on Analysis of variance(ANOVA) repeated measures between groups for each time cycles(p<0.001). This modality may have benefits when used early stage in the muscle damage.

목적: 급성 전방십자인대 손상 환자에서 조기 재건술과 지연 재건술 간의 관절 강직 발생 정도와 임상적 결과를 비교하고자 하였다. 대상 및 방법: 2008년 3월부터 2010년 10월까지 급성 전방십자인대 손상 환자 중 전방십자인대 재건술을 시행한 34예를 대상으로 하였다. 수상 후 1주 이내에 재건술을 시행한 조기 재건군과 수상 후 3주에서 6주 사이에 재건술을 시행한 지연 재건군으로 나누어 수술 전까지 적극적인 관절 운동을 시행하고 술 후에 환자 스스로 운동이 가능하도록 하는 적극적인 재활 치료를 시행한 후 관절 운동 범위, Lachman 검사, pivot shift 검사, Lysholm 점수, International Knee Documentation Committee (IKDC) 점수, Tegner 활동도 점수를 이용하여 평가하였다. 결과: 최종 추시에서 Lysholm 점수는 조기 재건군 91.82점, 지연 재건군 94.83점이었고 IKDC 점수는 전례에서 B (거의 정상) 이상으로 회복되었다(P=0.217, P=0.845). Tegner 활동도 점수는 조기 재건군 6.7점, 지연 재건군 7.1점이었고 (P=0.840) 관절 운동 범위는 양군 간에 차이가 없었으며(P=0.873, P=0.873) 심부 정맥 혈전증이나 감염은 전례에서 발생하지 않았다. Lachman 검사, pivot shift 검사 결과도 양군 간에 유의한 차이는 없었다(P=0.606, P=0.118). 결론: 급성 전방십자인대 손상 환자에서 조기 및 지연 재건군 모두에서 만족할만한 임상적 결과를 얻었다. 따라서 수상 후 1주 이내에 시행하는 조기 재건술도 좋은 치료 방법의 하나로 선택될 수 있을 것이라 생각된다.
