In this study, we investigated the effects of high-intensity interval exercise on blood lipids and renin-angiotensin system (RAS)-related factors in ovariectomized rats. The rats were categorized into a control group (CON, n=10), an ovariectomized group (OVA, n=10), and an ovariectomized+high-intensity exercise group (OVA+HIE, n=10). High-intensity interval exercise was performed on a treadmill for 30 min per session, once a day for 12 weeks. Data was analysed using one-way analysis of variance (ANOVA). Compared with the other groups, the total cholesterol, triglyceride, and low-density lipoprotein cholesterol levels were significantly reduced and the high-density lipoprotein cholesterol levels were significantly increased in the OVA+TE group after 12 weeks of high-intensity interval exercise. Additionally, ACE1 and AT1R mRNA expression were significantly reduced in the OVA+TE group. However, no significant intergroup difference was observed in SERCA2a mRNA expression. These results highlight that 12-week high-intensity interval exercise produced a positive effect on blood lipids and RAS-related factors in ovariectomized rats.

This study is about changes in antioxidant response during repeated apnea diving. The subjects are 16 male university students. The method is to measure MDA, SOD, red blood cell, lactic acid, blood suger, blood and heart rate at rest, after 5, 10, 15 and 20 times of repeated apnea diving in 5M diving pool. One-way ANOVA with repeated measure was performed to verify the difference in the mean between periods, and the LSD method was performed for post-hoc testing if there was any significance between groups. the statistical significance level was set as α=.05. As a result, there were significant differences in white blood cells, red blood cells, hemoglobin, hematocrit, blood glucose, lactic acid, and heart rate changes according to the number of times and time, but there were no changes in MDA and SOD. This showed that the intensity of apnea diving was low in male college students and there was no significant difference due to physical adaptation. Therefore, in future studies, in-depth studies of various variables appearing during apnea diving in various environments and conditions are required.

In this study, variables, like respiration response, fatigability, heart-rate, were estimated the physiological effect of new poomsae training. The subjects were 10 national team grade athletes. They were informed not to take any intake 4 hours before the experiment. The subjects were measured with equipments while processing the performance of new poomsae and Taeback. The performance was done only once per day to set identical environment. Himchari was shown as the longest in performance time. Also, all four new poomsaes were significantly different from Taeback. Lactate shows that Himchari was the highest and all four new poomsae were significantly different from Taeback. Among the new poomsaes, no significant difference were shown in VO₂peak. However, clear significant difference were shown between all four new poomsaes and Taeback. VO₂average and HRpeak showed the same tendency as VO₂peak. However, HRaverage showed that only Bigak and Himchari were significantly different from Taeback. Kcal showed significant difference between new poomsaes and Taeback except Nareusya. For the 5 sections of each new poomsae, each variables showed difference, which is considered due to performance time, number of motions and level of difficulty. With this study, new poomsae could be considered as more intensive training program than previous poomsae. This study can be used as basis for the further study.

This study was to investigate the effects of treadmill exercise on inflammatory cytokines expression and antioxidant enzymes activity in prostate tissue of BPH-Induced rat. At 6 weeks of age, male S.D rats(N=36) were randomly assigned to : sham operation group(SO, n=12), BPH group(BPH, n=12), BPH+treadmill exercise group(BPH+TE, n=12). Rats in the exercise group run on a treadmill at a speed of 12-25m/min for daily (30-40 min/day) for 12 weeks. After 12 weeks treadmill exercise, serum IL-1β and TNF-α levels were significantly decreased in exercise groups compared with BPH group(p<.01). IL-6 and COX-2 mRNA expression in Prostate Tissue were significantly decreased in exercise groups compared with BPH group(p<.01). In the Prostate Tissue, SOD and GPx activities were significantly increased in exercise groups compared with BPH group(p<.01). In conclusion, the results of this study indicate that treadmill exercise improved BPH status by activation of antioxident enzymes and reduce of inflammatory cytokines in prostate tissue of BPH-Induced rat.

본 연구의 목적은 16주간 트레드밀 운동이 난소절제 쥐 해마의 신경전달물질 및 신경가소성 단백질 발현에 미치는 영향을 관찰함으로써 운동이 뇌 기능 변화에 대한 기초자료를 제공하고자 한다. 본 연구는 25주령의 Sprague Dawley계 암컷 쥐를 대상으로 통제집단(n=12), 난소절제 통제집단(n=12) 및 난소절제 트레드밀 운동집단(n=12), 총 세 집단으로 구분하였다. 난소절제 트레드밀 운동집단은 16주간 주 5일, 1일 40분, 25 m/min의 속도로 트레드밀 달리기 운동을 실시하였다. 16주간 트레드밀 운동 후 해마의 신경전달물질, 신경가소성 단백질 발현 및 기억력 변화를 분석한 결과 다음과 같은 결과를 얻었다. Serotonin 함량은 난소절제 트레드밀 운동집단은 난소절제 통제집단과 비교하여 유의하게 증가하였다. 그러나 AChE mRNA 발현은 난소절제 트레드밀 운동집단이 난소절제 통제집단과 비교하여 유의하게 감소하였다. BDNF mRNA 와 synapsin Ⅰ mRNA 발현은 난소절제 트레드밀 운동집단이 난소절제 통제집단과 비교하여 유의하게 증가하였다. 수동회피실험을 실시한 결과, 난소절제 트레드밀 운동집단은 난소절제 통제집단과 비교하여 조명이 켜진 방에 머문 시간이 유의하게 증가하여 기억력이 향상된 결과를 나타냈다. 이상의 결과를 종합하면 16주간 트레드밀 운동은 난소절제 쥐 해마의 뇌 신경전달 물질과 신경가소성 관련 단백질 발현에 긍정적 변화를 가져오며, 기억력 개선에 영향을 미치는 것으로 나타났다. 이와 같이 트레드밀 운동이 신경전달 물질 및 신경가소성 단벡질 발현이 증가됨으로써 뇌 신경세포를 보호하고, 시냅스가소성에 영향을 주어 기억력 기능에 긍정적 영향을 미친 것으로 생각된다. The aim of this study was to investigate effects of 16 weeks treadmill exercise on neurotransmitter and neuroplasticity protein expression in ovariectomized rats. Twenty-six weeks+ old Sprague Dawley female rats were assigned to three groups(N= 36): healthy normal control group(CON, n=12), ovariectomized control group(OVX+ CON, n=12), and ovariectomized treadmill exercise group(OVX+TEX). The rats were forced to run on the treadmill (5 days/week) for 30 min daily for 16 weeks at a speed of 25 m/min. After 16 weeks of treadmill exercise, serotonin levels, BDNF mRNA, synapsin Ⅰ mRNA expression in the hippocampus were significantly increased in ovariectomized treadmill exercise group compared with ovariectomized control group. However, AChE mRNA was significantly decreased in ovariectomized treadmill exercise group compared with ovariectomized control group. Also, 16 weeks treadmill exercise improved the and short-term memory in the in ovariectomized rats. These results suggested that in ovariectomized rats, 16 weeks treadmill exercise may benefit short-term memory by improvement of hippocampus neuroplasticity related factors mRNA expression and neurotransmitter.

The purpose This study compared the ski instructor education system of Canada, known as an advanced country in overseas skiing, to strengthen the capabilities and cultivate leadership of domestic ski instructors. Accordingly, the purpose of the study is to derive implications for the curriculum, content, and evaluation of domestic ski instructors. This study analyzed data using a literature analysis method. In order to select cases for study in this study, Canadas ski instructor system was set as an advanced example based on countries that have consistently maintained winning records in various world competitions. Canadas ski instructor curriculum, content, and evaluation were set as a unit of analysis to collect data and conduct content analysis. As a result of the study, there is no pre-certification education program in the domestic ski instructor training program, and the qualification system is implemented through written experiments and practical ability tests. Accordingly, it is believed that if new field-centered ski instructor education programs and certification contents are developed and managed through the Canadian ski instructor qualification system, the ski participation population will increase and the educational capabilities of ski instructors will be improved.
