In this study, the researcher discussed the requirements for the establishment of the exercise prescription professionals curriculum(EPPC) in university, and suggested the basic principle and direction in programing the EPPC and thereby tried to design the proper model of EPPC in Korea. There may be three aspects of reasons which the EPPC in university must be established in this period. First, the establishment of the EPPC in university maybe can meet the increased social requirement for the exercise prescription professionals who can recommend the regimen of physical activity or exercise designed in systematic and individualized manner to a population who have various levels of physical fitness and health condition. Second, the establishment of EPPC in university may serve as a momentum that the area of sports and leisure study can be developed as the area that have still more competitive power and characteristics to be distinguished from other area connected to physical activity. Third, the establishment of EPPC maybe provide the leaders in the area of sports and leisure study with a good opportunity to extend the field of activity and to improve the social recognition for the leaders. The programing the EPPC must have the follow foundmental direction, that is, 1) education for the sense of duty and the sprit of professional 2) education not to be departed from the indigenous characteristics that the area of the sports and leisure study has possessed. 3) education to strengthen the experiment and practice 4) education to cultivate the ability to consult the various participants about their health problems. 5) education to cultivate the ability as a researcher to collect and analyze the update data, and to develope the new exercise program. 6) education to cultivate the ability to operate and manage a sports clinic, exercise prescription center, or health care center. The following matters in operating the EPPC must be considered carefully. 1) Improvement of the educational environment such as experimental facilities and equipments: the operation of a profitable health/fitness care or exercise prescription center. 2) Supplement of faculty: enlargement of interchange personal among other study`s area and university. 3) Development and operation of the still more specialized curriculum. 4) Activation of the extracurricular work and field practice. 5) Many-sided study on the rational screening test method to select the students to apply for the major in exercise prescription.

This study was done in order to investigate the changes of segmental body composition, ie, body fat, FFM, and bone mineral content(BMC) according to aging in Korea adult woman and to evaluate the effect of body components on the bone mineral density. The subjects were composed of 86 healthy adult women who were 17 - 66 years old and they were divided three groups according to age(A group : 17-30 yrs., B groups : 31-50 yrs., C groups : more than 51 yrs.). The results were as follows : 1. Among the body components, fat mass had the highest correlation with the weight (r=0.9037. p≤0.001) and each segmental FFM showed the greatest influence on bone mineral content (r = 0.49 - 0.67) and followed by weight and body fat. 2. A significant difference among three age groups was not discovered in muscle mass of arm and trunk region, but the muscle mass in leg region represented the remarkable declination acording to aging(p≤0.001). 3. The fat mass of arm and trunk region in C groups(≥51yrs) were significantly higher than that in younger groups(p=0.003) and the fat mass of leg region in a group (17-30yrs) was significantly lower than that in older groups(p=0.001). 4. C group(≥51yrs) had significantly lower total BMC, total BMD and every segmental BMC than younger age groups(p=0.0000-0.0006). These results suggest that in about the period of menopause in women proper diet balance and weight-bearing exercise may be required to prevent from the abrupt decrease of BMD and muscle mass, especially in leg region, and the increase of body fat, especially in trunk region.

The study was done in order to evaluate the effects of 12-weeks training on the pituitary-adrenal hormones, ACTH and cortisol, in 11 healthy male volunteers who were mean 35.27±2.97 hormones, ACTH and cortisol, in 11 healthy male volunteers who were mean 35.27±2.97 years old. All subjects performed the weight resistance and aerobic treadmill exercise during about 90 minutes more than 3 times per week throughout whole experimental period. They warmed up with 60rpm at 50watts and thereafter the work rate was gradually increased 25 watts every 2 minute until exhaustion. From the maximal exercise, various performance indexes such as VO_2max, anaerobic threshold etc, were measured. After gradual maximal exercise, all subjects performed continuous submaximal exercise at he work load comprised to their 65%VO_2max level during 40minutes. Blood samples during submaximal exercise were taken from each subject`s antecubital vein total 5times(pre-exercise, during 10min, 20min, and 40min exercise, and recovery 30min) by catheter and analyzed for plasma ACTH, cortisol, and lactate concentration. These all procedures were taken again after 2 week training. Statistical techniques for data analysis were applied repeated ANOVA and paired T-test and the 5% level of significance was used as the critical level for aception of hypotheses fot the study. In summary of results, the maximal oxygen uptake(from 41.25㎖/kg/min to 43.89 ㎖/kg/min, p<0.05) and ventilation threshold(from 70.29%VO_2max to 72.46%VO_2max, p<0.05). These improvement of fitness level be attendant on the increase of ACTH responsiveness to same submaximal work load(65%VO_2max), but not cortisol. These results were caused by the lower intensity of this study than anaerobic threshold, but probably respresented that the training might stimulate the responsiveness of HPA axis hormones.

The aim of this study was to examine the effect of acute administration of L-Carnitine on blood energy metabolism, blood gases and performance. Thus, The comparative analysis on the effect of lactate, RER, NH_3, pH, pO_2, pCO_2, peakVO_2 and all out time during maximal graded exercise through the acute administration of L-Carnitine 3g(β-hydroxy-γ-[trimethylammonia]-butyrate; Vitamin BT. SIGMA, USA) was conducted to 5 male wrestlers. The obtained results are as follows: 1. In the reaction of blood energy metabolism, the reaction of lactate, RER, NH3 were no significant differences between L-Carnitine group and placebo group. But, There was significant change in two groups according to duration. 2. In the reaction of blood gases, the reaction of blood pH, pO_2, pCO_2 value were no significant differences between L-Carnitine group and placebo group. But, There was significant change in two groups according to duration. The value of pH and pCO_2 was significantly decreased after maximal exercise compared to before exercise and rapidly increased in the recovery phase. But, pO_2 was significantly increased after maximal exercise compared to before exercise and rapidly decreased in the recovery phase. 3. In performance indices, the reaction of maximal oxygen uptake(peakVO_2) and All out time were no significant differences between L-Carnitine group and placebo group. In conclusion, these results indicate that L-Carnitine acute administration does not provide an ergogenic effects related to fatty acid oxidation during graded maximal exercise.

In the present work we investigated the effect of regular physical exercise on plasma lipid profile and antioxidant vitamin level in 89 healthy male, aged 18-25years. The study population were divided in three groups SG(Sedentary Group, Exercise time 2.98±3.58 h/week, n=34), RAG(Regular Active Group, Exercise time - 8.176.34 h/week, n=24), and HTG(High Trained Group, Exercise time ' 19.33±7.70 h/week, n=31,Exercise career - 9.42±343 year) according to their physical exercise habits measured by a questionnaire. Plasma lipid profiles level were determined by TC (total cholesterol), TG(triglyceride), HDL-C(high density lipoprotein cholesterol), LDL-C(low density lipoprotein cholesterol), AI(atherogenic index) and antioxdant vitamins Jevel were determined by Vitamin C, Vitamin E( a -tocoperol, 7 -tacoperol). The results are summerized as follows ' 1) Plasma TC, TG, HDL-C, LDL-C level were no significant differences between the three groups. However, Plasma HDL-C level in RAG & HTG were higher than SG. 2) AI (atherogenic index) level were lower in BAG 8: HTG but not significantly than SG. 3) Plasma vitamin C level were significantly (p<05) higher in RAG than SG k HTG. 4) Plasma a -tocopherol level were signi5cantly (p<05) higher in RAG & HTG than SG. Plasma a-tocopherol level in RAG has great values. 5) Plasma l -tocopherol level were higher in RAG but not significantly than SG & HTG. In conclusion, regular physical exercise was shown to positive influence on increasing HDL-C level and antioxidant vitamin.

The study was done in order to evaluate the effects of different training on the segmental bone mineral density and body composition. Only eighteen women of total thirty participants who were 33-47 years old accomplished the 12-week training and pre- and post test and blood sampling. Each six-subjects were assigned to three training groups(Swimming groups, Bicycling groups, and Cross-training group: swimming + weight training). All subjects were tested for the segmental body composition and BMD by the DEXA and SBIA and blood lipid before and after 12 week training. Each subjects performed the submaximal exercise at 60-70%HRmax(execpt weight training) during 50 minutes five times per week. The result were as followed: 1. The percentage of body fat was decreased more significantly in bicycle erometer group(17.7%, p≤0.01) than other groups and the lean body mass measured by DEXA also represented more remarkable increase in cross-training group(11.7%). In the segmental body lean mass, cross-training group showed most significant increase of 11.0% in the arm region, while in the trunk and leg region bicycle exercise group showed the highest increase of 8.3% and 14.8%, respectively. 2. In the segmental BMD, only cross-training group showed the statistical significant increase of 10.7% and 2.2%(p≤0.01) in arm and trunk BMD. The leg BMD was most remarkably increased 7.3% in bicycle group, but there was no significant difference between pre and post training. 3. In segmental skinfold thickness, the most noticeable change was recorded in upper central trunk legion of all three groups(-12.3%~-26.5%). Cross-training group showed most remarkable decrease in upper and lower trunk legion, and the swimming group in lower trunk region, and the bicycle group in lower limbs region. 4. In the level of blood lipid, cross-training group showed the significant decrease(-11.2%, p≤0.05) of total cholesterol. The blood triglyceride represented relatively large decrease after 12 weeks training in all groups, but the changes were not statistically significant.

다양한 형태의 필드활동이나 운동 중 산소 섭취량과 에너지 소비량을 측정하기 위해 휴대용 무선 가스분석기가 많이 이용되고 있다. 하지만 휴대용 무선 가스분석기의 정확성에 관한 연구는 부족한 실정이다. 목적: 따라서 본 연구는 최근 가장 널리 사용되고 있는 Cosmed K4b2 (K4b2) 휴대용 무선 가스분석기의 정확성을 Parvo Medics TrueMax 2400 (MC) 가스분석기에 근거하여 비교, 측정하였다. 연구방법: 본 실험을 위해 남녀 8명 (연령=27.75±6.43, 신장=169.84±10.14 cm, 체중=73.90±20.94kg)의 피검자가 트레드밀 운동을 실시하였으며, 각기 다른 운동 강도 (최대 산소 섭취량의 100%, 65%, 45%)에서의 K4b2 정확성을 평가하기 위해 O2(mL·kg-1·min-1 and L·min-1), CO2(L·min-1), FeO2(%), FeCO2(%), respiratory exchange ratio(RER), minute ventilation(VE, L·min-1), and energy expenditure(EE, kcal·min-1)가 측정되었다. K4b2의 측정변인에 대한 통계적 유의성 검사를 위해 2×3(가스분석기×운동강도) 반복측정 변량분석(ANOVA with repeated measures)을 실시하였으며, 통계적 유의성이 있을시는 Sidak adjustments가 실행되었다. 모든 통계적 유의수준은 p≤0.05로 설정되었다. 결과: MC와 비교해볼때 K4b2에서 측정된 RER (p≤0.001)과 VE (p≤0.05) 값은 통계적으로 유의하게 나타났으나 그 외의 다른 모든 측정변인들은 운동강도와 상관없이 두 가스분석기 간에 매우 유사한 것으로 나타났다. 또한 Bland-Altman분석에 의하면, K4b2에서 측정된 VO2 (mL·kg-1·min-1 and L·min-1), VCO2 (L·min-1), TV (L), and EE (kcal·min-1) 수치는 MC에서 측정된 값과 매우 밀접한 관계를 보였다. 결론: MC 가스분석기와 비교해볼 때 휴대용 무선 가스분석기 K4b2에 의해 측정된 RER과 VE 수치가 높게 나타났지만 이를 제외한 다른 모든 변인들은 두 가스 분석기 간에 매우 밀접한 결과를 보였다. 따라서 본 연구 결과는 휴대용 무선 가스분석기 K4b2는 다양한 운동강도에서 산소섭취량 및 에너지 소비량을 측정하는 데 적합함을 입증하였다.
