융복합을 활용한 인터벌 태권도가 중년비만여성의 코티졸, 유리지방산 및 근 손상지표에 미치는 영향
권중호,김현태 한국융합학회 2016 한국융합학회논문지 Vol.7 No.6
본 연구는 인터벌 태권도 프로그램을 통하여 중년비만여성들의 코티졸, 유리지방산 및 근 손상지표에 어떠 한 변화가 나타나는지를 알아보고자 하였다. 이를 위해 중년비만 여성을 대상으로 최대심박수를 활용한 80∼85%의 운동강도로 매회 40분간 실시되는 인터벌 태권도 운동을 주 3회씩 8주간 실시하였으며, 다음과 같은 결과를 얻었 다. 첫째, 코티졸은 8주간 인터벌 태권도 프로그램 전․후 감소를 보였으나 유의한 변화는 나타나지 않았다. 둘째, 유리지방산은 8주간 인터벌 태권도 프로그램 전․후 감소를 보였으며 유의한 변화가 나타났다. 셋째, 근 손상지표는 8주간 인터벌 태권도 프로그램 전․후 감소를 보였으나 유의한 변화는 나타나지 않았다. 본 연구결과를 통해 인터벌 태권도 운동은 스트레스를 이겨내는 내성 및 저항력 향상과 근 손상 예방 효과는 다소 낮았으나, 지방 산화 능력 증가를 위한 운동 프로그램으로 활용될 수 있을 것이라는 결론을 얻었다. This study was built to figure out the changes in Cortisol, Free fatty acids and muscle damage indicators, by conducting eight-week interval Taekwondo programs to obese women in their middle age. The exercise programs was consisted of 40 minutes interval Taekwondo workout each time, using the movement of the 80-85% of HRmax intensity. Overall, we got the following conclusions as a result of the conduct. First, Cortisol decreased before and after the 8 week interval, but it did not show a significant change. Second, the FFA showed a significant change by decreasing before and after the 8 week interval. Third, the muscular damage indicators showed a small decrease before and after the Taekwondo workout, but didn't show a significant change. Ultimately, the interval Taekwondo program didn't have a significant effect on improving stress tolerance, stress resistance and protecting muscle injuries, but can be effectively used to increase the lipid oxidation ability.

일회 지구성 트레드밀 운동이 노화쥐 골격근 내 AMPK와 MAPK 발현에 미치는 영향
권중호,어수주 한국스포츠학회 2011 한국스포츠학회지 Vol.9 No.4
The purpose of this study was to determined the effect of endurance treadmill running exercise on expression of AMPK and MAPK in aging rat muscle. Total 32 Sprague-Dawley rats were divided into two groups by age; young group(YG; 12wk; n=16) or aging group(AG; 80wk; n=16). Each experimental group was further allocated two subgroups; Exercise(EX; n=8), Control(CON; n=8) group. All animals in exercise group performed one bout of endurance runing exercise (12m/min for 60min). The expression of phospho-AMPK by endurance exercise was significantly increased in the YG & AG. The ERK 1/2(p<.001) and p38 mitogen-activated protein kinase (MAPK)(p<.05) phosphorylation by bout endurance exercise significantly incresed in YG but decreased in AG. These results suggested that aging was significantly decreased the expression of MAP Kinase by acute endurance treadmill exercise. In conclusion the acute endurance exercise is effective in YG than AG.

저장온도 및 포장조건이 건멸치의 이화학적 품질에 미치는 영향
권중호,정형욱,변명우,김정숙 한국식품위생안전성학회 1995 한국식품위생안전성학회지 Vol.10 No.2
For improved preservation of boiled-dried anchovies, the current preservation method of corrugated-cardboard box packaging and freezing below -18$^{\circ}C$ was compared to the nylon/polyethylene(NY/PE) packaging along with cooling temperature ranging from 5$^{\circ}C$ to 1$0^{\circ}C$ as well as ambient condition for eight months by determining physicochemical quality of stored samples. Lipid oxidation of stored anchovies and their browning increased with storage time. The phenomenon was delayed under the conditions of lower temperature and air-tight packaging. As quality-indicative criteria of stored anchovies, carbonyl value(r=-0.989), browning (r=-0.949) and color a value(r=-0.989), browning(r=-0.965), Hunter's color b value(r=-0.949) and color a value(r=-0.940) showed a highly-negative correlations with organoleptic qualities of the samples. Based on the above results, air-tight packaging in a laminated film and subsequent storage at cooling temperature was found to be a possible alternative to the current freezing-storage of boiled-dried anchovies from the physicochemical point of view.
