본 연구는 중년 여성의 건강 관리와 비만 예방에 있어 중요한 요소로 알려진 걷기 운동의 경사도에 따른 에너지 대사 변화를 분석하는 것을 목적으로 하였다. 연구 대상은 50대 여성 20명으 로 선정되었으며, 각기 다른 경사도(0%와 6%)에서 VO2max의 50%, 60%, 70% 강도로 운동을 수행하도록 하였다. 실험은 트 레드밀을 이용하여 진행되었으며, 호흡가스분석기를 통해 에너지 소비량과 지방 연소량을 측정하였다. 그 결과, 지방연소량은 경사 도 6%가 0%에 비해 유의하게 높게 나타났다. 하지만 강도에 따 라 에너지소비량은 증가하였으나 0%와 6%의 경사도에서는 차이 가 나타나지 않았다. 이 연구는 중년 여성의 비만 예방을 위한 효 율적인 운동 강도와 경사도 설정에 기초 자료를 제공할 수 있다.

본 연구의 목적은 12주간 수중걷기운동이 비만 노인 여성의 신체조성, hs-CRP, HOMAIR 및 혈압에 미치는 영향을 알아보기 위하여 실시하였다. 체지방률 30% 이상인 비만 노인 여성 중 운 동군(10명), 대조군(10명)으로 총 20명으로 실시하였으며, 모든 검사항목은 동일한 방법과 조건으로 신 체조성, hs-CRP, HOMA-IR 및 혈압을 사전, 사후 총 2회 측정하였다. 수중걷기운동은 12주간, 주 3 회, 1회 50분, RPE 11-14 강도로 실시하였다. 측정변인에 대해 평균값과 표준편차(M±SD)를 산출한 후 사전 운동군과 대조군의 신체적 특성과 각 측정변인에 대한 동질성 검정을 위하여 독립 t-test를, 집 단 내의 사전·사후 평균치 변화에 대한 차이 검증은 종속 t-test를, 집단 간 차이에 대한 주효과 검정 및 집단 간 시기 간 상호작용 효과는 반복측정 분산분석을 이용하였다. 본 연구결과 운동군에서 신체조성, 체지방률(p<.05), 인슐린(p<.01), HOMA-IR(p<.01) 및 수축기 혈압(p<.05)이 유의하게 감소하였다. 따 라서 수중걷기운동이 비만 노인 여성의 비만 및 심혈관질환의 개선에 도움을 줄 수 있을 것으로 사료 된다.

Background: Backward walking exercise may offer some unique and potentially beneficial differences compared with forward walking exercise. There is still a lack of research on backward walking exercises and forward head posture. Objects: The purpose of this study was to determine the effect of backward walking exercise on college students forward head posture in their 20s. Methods: Twenty-one subjects participated in the experiment. The subjects were those with a craniovertebral angle (CVA) of 55 degrees or less who understood the purpose and method of this study and voluntarily agreed. A camera capable of taking pictures of the lateral plane was installed at a distance of 1.5 meters before exercising. Pictures were taken before walking backward, and after walking for 15 minutes on the treadmill, the images were taken in the same way. The composition of the backward walking exercise was walking at a rate of 1.0 for 5 minutes, and the remaining 10 minutes were walking at a rate of 1.5. Wilcoxon signed rank test was used to compare CVA and craniorotational angle (CRA) before and after exercise. Results: As a result of this study, there was a significant difference in CVA before and after exercise (p < 0.05). There was a significant difference in CRA before and after exercise (p < 0.05). Conclusion: The backward walking exercise and verbal command seems to have positively influenced the changes in CVA and CRA among college students in their 20s. It seems that studies to confirm balance or muscle activity as well as changes in forward head posture through the long-term intervention of the backward walking exercise should be conducted.

The purpose of this study is to design and develop integrated game system for experiential walking exercise. Existing walking exercise is performed outside, so it is influenced by external weather, temperature, time, place and other situation information. Therefore, it is necessary to have an experiential walking exercise game that can induce the recommended level of physical activity for the elderly who have a low interest in health care. The experiential exercise game requires a vision - based system to recognize motion and a smart mat that can recognize walking information. We also developed a walking exercise program to improve the sense of balance and cognitive ability of elderly people. There are 4 types of Walking Exercise Games: 5 levels for beginner, intermediate, and advanced difficulty levels.

The purpose of the study was to investigate the effectiveness of self-paced walking exercises in elderly women with hypertension, hyperglycemia, and hypercholesterolemia. Thirty-eight elderly women with hypertension, hyperglycemia, and hypercholesterolemia (16 hypertension, 11 hyperglycemia, 11 hypercholesterolemia), aged between 65 and 80, were invited to participate in this study. Each subject participated in a self-paced walking exercise five times a week for twelve weeks from 26 June to 16 September 2006. The changes between pre- and post-exercise were analyzed using the analysis of a paired t-test with the SPSS version 12.0 package program. There were significant decreases in systolic blood pressure (p<.01) and diastolic blood pressure (p<.05), blood glucose(p<.05), and cholesterol in the blood (p<.01). These results show that self-paced walking exercises may be helpful in treating elderly women with hypertension, hyperglycemia, and hypercholesterolemia.
