여성 어르신의 신체활동 빈도에 따른 혈중지질, 인지능력의 차이
정한상,이봉근 한국스포츠학회 2017 한국스포츠학회지 Vol.15 No.3
본 연구는 65세 이상의 여성 어르신 18명을 대상으로 6개월간 신체활동 참여빈도(무활동, 주 3회, 주 5회)에 따 라서 혈중지질과 인지능력의 차이를 분석하였으며, 노인체육 지도자와 어르신들에게 신체활동 수행의 절대성과 인식을 돕기 위한 기초자료를 제공하고자 한다 . 연구 결과에서 주 3회 및 5회 수행하는 어르신들은 신체구성, 혈중지질과 인지 능력이 무활동 어르신에 비해 긍정적인 결과를 나타내었으며, 특히, 주 5회 수행 어르신들은 근육량, 고밀도 지단백 콜 레스테롤(HDL-C), 신경반응 속도에서 통계적으로 유의한 의미가 나타났다. 이와 같은 결과는 어르신들의 원활한 일 상 활동을 위한 기능적인 면에 긍정적인 영향을 줄 것이며, 질병 및 사고 위험을 예방할 수 있을 것이라 생각된다. 따라서 어르신들에게 있어 주3회 이상 규칙적인 신체활동을 필히 제안한다. This study aimed to analyze the difference of blood lipid and cognitive ability according to frequency of physical exercise participation with 18 female elderly people for 6 months and also to provide basic data for helping Physical activity of older adults teacher and elderly people raise their awareness of the necessity of physical activity. The result showed that the elderly who exercised 3 or 5 times a week had the positive result in their blood lipid and cognitive ability compared to the ones who did no exercise. Especially, the elderly with exercising 5 times a week showed statistically signigicant results in muscle volume, HDL-C, and motor nerve velocity. This result can have positive effect on preventing diseases and accident risk as well as on functional side for elderly people’s effective daily living. Therefore, exercising regularly more than 3 times a week is strongly recommended for elderly people.

정한상,이남주,박석 한국운동영양학회 2016 Physical Activity and Nutrition (Phys Act Nutr) Vol.20 No.2
Purpose: The purpose of this study was to determine the interaction of ACTN3 gene polymorphism and muscle imbalance effects on kinematic efficiency changes in combat sports athletes. Methods: Six types of combat sports athletes (Judo, Taekwondo, boxing, kendo, wrestling, and Korean Ssi-reum) participated in the study. ATCN3 gene polymorphism and muscle imbalance in lower extremity were evaluated followed by analysis of differences of moment in hip, knee, and ankle joint during V-cut jumping and stop. To examine the moment difference due to an interaction of ATCN3 polymorphism and muscle imbalance, all participants were divided into 4 groups (R+MB, R+MIB, X+MB, and X+MIB). Results: There was no significant difference of hip, knee, and ankle joint moment in R allele and X allele during V-cut jumping and stop based on ACTN3 gene polymorphism. Otherwise, muscle imbalance of knee moment in X-axis and ground reaction force of knee in Z-axis showed a higher significance in muscle imbalance during V-cut jumping and stop compared to muscle balance (p<0.05). In addition, joint analysis showed that muscle imbalance in X allele group had significantly higher knee moment of V-cut ground reaction force in X-axis and higher ankle moment of jumping ground reaction force in X and Z-axis compared to muscle balance with R and/or X group (p <0.05). Conclusion: This study confirmed that muscle imbalance in lower extremity of combat athletes might induce higher risk factors of sports injury incidence than genetic factor and training might reduce the ratio of sports injury risk incidence.

여성노인의 노쇠정도에 따른 기능체력 및 일상생활수행능력과의 관계
정한상 한국사회체육학회 2020 한국사회체육학회지 Vol.0 No.82
Purpose: The purpose of this study is to identify the effects of frailty on functional fitness and ADL in the elderly. Method: The study was conducted on 59 elderly women at senior welfare centers in Seoul and Gyeonggi Province. The collected data were derived using the SPSS 23 program through technical statistical analysis, one-way analysis, correlation analysis, and multiple regression analysis. Results: As a result of the analysis, the higher the level of senili,t ythe lower the functional stamina, and th e higher the level of senility, the lower the ability to performd aily life. The degree of senility was found to hav e an effect on lower extremity muscle strength and cardiorespiraotry endurance among functional physica l strength. Therefore, to prevent aging, it was considered thatt iwas necessary to prevent it from middle ag e and to maintain and improve physical strength. Conclusion: This study could be used as basic data when developing a preventive exercise program as well as predicting and evaluating old age. However, since the study was conducted only by elderly women living in the community, it is necessary to expand the size of the samp lein the future as the findings are limited to the overall elderly population.

유ㆍ무산소 혼합운동이 중년여성의 신체조성 및 호르몬에 미치는 영향
정한상 한국스포츠학회 2020 한국스포츠학회지 Vol.18 No.3
본 연구에서는 유ㆍ무산소 혼합운동이 중년여성들의 신체조성 및 심리적 호르몬인 도파민과 세로토닌에 어떠한 영향을 주는지 규명하여 중년여성의 비만 관리 및 심리적 예방․치료에 도움을 주고자 하는 데 그 목적이 있다. 본 연구의 대상은 휘트니스클럽에 신규 등록 여성 40~60세 30명으로 선정 하였으며, 대상자 집단 구분은 무산소운동 10명, 유산소 운동 10명, 유ㆍ무산소혼합운동 10명으로 무선배정하였다. 자료분석은 SPSS 25.0 통계 프로그램을 활용하여 기술통계분 석과 이원변량분석을 실시하였다. 본 연구 결과 첫째, 체지방률과 근육량의 변화가 혼합운동을 수행한 집단이 유산소운동 과 무산소운동만을 수행한 집단보다 더 높은 감소와 증가가 나타났다. 둘째, 유ㆍ무산소 혼합운동을 실시한 집단이 유산소 운동과 무산소운동을 각각 수행하는 집단보다 도파민과 세로토닌의 증가 변화가 더 큰 것으로 나타났다. 이상의 결과를 종합해 볼 때, 중년여성에게 유ㆍ무산소 혼합운동은 신체조성과 도파민과 세로토닌의 감소를 지연시켜 중년여성의 노화지 연은 물론 우울증상과 같은 심리적인 요인에도 긍정적인 효과가 있을 것으로 사료된다. The purpose of this study is to help middle-aged women manage obesity and prevent and treat psychological treatment by identifying how the mixed exercise affects dopamine and serotonin, the body composition and psychological hormones of middle-aged women. The subjects of this study were selected as 30 newly registered women between the ages of 40 and 60 in the fitness club, and the group of subjects was assigned wirelessly to 10 in the anaerobic movement, 10 in the aerobic exercise, and 10 in the lactobacillus-free mixed movement. Using the SPSS 25.0 statistical program, the data analysis was conducted with descriptive analysis and two-way ANOVA with repeated measurements. The results of this study showed that, first, changes in body fat rate and muscle mass showed a higher decrease and increase in groups that performed mixed exercises than those that performed only aerobic and anaerobic exercises. Second, it was found that the group that conducted the mixed lactobacillus and anaerobic exercises had a greater change in dopamine and serotonin than the group that carried out the aerobic and anaerobic movements respectively. To sum up the above results, the mixed lactose and oxygen-free movement for middle-aged women is believed to have a positive effect on psychological factors such as depression as well as delays in aging in middle-aged women by delaying body formation and reducing dopamine and serotonin.
