노화 과정에 따라 중년 여성들은 폐경 이후 체력이 저하되기 시작하면서 체지방 증가와 제지방량의 감소로 비만으로 이어지기 쉽고, 이러한 현상은 체내 호르몬의 분비의 변화와 함께 발생된다. 본 연구는 서킷 트레이닝이 비만 중년 여성의 노화 관련 호르몬에 미치는 영향을 구명하기 위해 실시하였다. 대상자 체지방률 30% 이상인 비만 중년 여성 운동군 10명, 대조군 10명 총 20명을 실시하였다. 운동 시간은 준비운동 5분, 본 운동 20분, 정리운동 5분으로 총 30분 주 3회 실시하였으며, 운동 강도는 운동자각도를 이용하여 13~17(약간 힘들다-매우 힘들다)수준으로 실시하였고, 또한 POLAR 심박수 변화량을 측정하여 1~6주는 60~70%HRR (Heart rate reserve), 7~12주는 70~80%HRR로 설정하였다. IGF-1은 운동군이 유의하게 증가하였으며, GH는 운동군이 유의하게 증가하였고, DHEA-S는 운동군이 유의하게 증가하였다. 이상의 결과 서킷 트레이닝이 비만 중년 여성의 노화 관련 호르몬에 긍정적인 영향을 준 것으로 사료된다. Due to aging, the physical fitness of middle-aged women decreases after menopause. This results in increased body fat and reduced lean body mass, both of which can lead to obesity. This phenomenon is accompanied by changes in hormone secretion in the body. The purpose of this study was to analyze the effects of circuit training on aging-related hormones in obese middle-aged women. The subjects were 20 obese middle-aged women. The subjects were divided into two groups: a circuit training group (n=10) and nonexercise control group (n=10). Growth hormone (GH), insulin-like growth factor-1 (IGF-1), estrogen, and DHEA-S were measured before and after the circuit training program. The circuit training group performed circuit training for 12 weeks, three times per week. Exercise intensity was increased gradually from 60% to 80% of heart rate reserve every 6 weeks. In the circuit training group, at the end of the 12-week training program, the IGF-1 levels were significantly increased compared to pre-exercise levels, and they were higher than those of the control group. GH levels were also significantly increased in the circuit training group, but the differences were not statistically significant. DHEA-S was significantly increased in the circuit training group, but the difference was not statistically significant. The results showed that circuit training improved aging-related hormones levels in obese middle-aged women.

Abstract : The purpose of this study was to compare plantar pressure and COP parameters in three types of arch support insole during stair descent in elderly with flatfoot. A total of 14 women elderly were recruited for this study. Pedar-X was used to obtain plantar pressure(peak pressure, mean pressure, and contact area) and COP(distance, displacement, excursion) parameters. One-way ANOVAs were used to compare peak pressure, mean pressure, and contact area, distance of COP, displacement of COP, and excursion of COP. Among the plantar pressure parameters, significant(p<0.05) differences were observed in M3 for the peak pressure, M2, M3, and M4 for the mean pressure, and M2, M3, and M6 for the contact area. Among the COP parameters, distances of COP both in the mediolateral and anteroposterior axes revealed significant(p<0.05) differences. The larger peak pressure values of type A and B insoles were observed as compared to normal insole. The larger peak pressure and shorter COP distance values of type A and B insoles were observed as compared to normal insole.
