기존의 운동량 측정방법들은 가속도 센서나 GPS, 심장박동, 체온측정 등의 정보를 이용하였으나, 각기 측정방식 및 측정환경 등의 제한으로 인해 정확한 신체활동 측정 및 분석에 어려움이 있었다. 이러한 단점을 극복하기 위해 본 논문에서는, 운동 시 발생하는 생체전기신호를 이용하여 유산소운동은 물론 기존에 측정이 어려웠던 근력운동에 대한 분석도 가능한 시스템을 개발하였다. 운동을 분석하기 위해 두개의 전극이 부착된 허리벨트를 착용해 운동 중 복부에서 발생하는 생체전기신호를 기록했고, 측정된 생체전기신호는 각각 상체 움직임 및 근육활동을 대표할 수 있는 주파수 대역으로 분리한 후, 분리된 각 신호의 파워 값과 차분의 파워 값, 그리고 중간주파수 값들을 운동형태 구분을 위한 특징값으로 추출하였다. 일원분산분석과 다중비교 분석의 통계적 검증을 통하여 추출된 특징값들의 유의성을 검증하였고, 또한 SVM분류기를 이용하여 운동의 형태를 구분하였다. 여섯 가지의 세부운동들을 분류하기 위해 두 가지의 분류방법을 적용하였고, 그 결과 유산소운동과 근력운동으로 분류 시 100%, 유산소운동과 근력운동 및 복합운동으로 분류한 경우 92.7%의 구분율을 보이며 운동형태의 분류가 가능하였다. 또한 유산소운동 및 근력운동의 양을 각각 수치화하여 표현 가능하다. 본 시스템은 기존의 유산소운동 기반의 운동량 측정방식대비 추가적으로 근력운동의 분석이 가능해짐에 따라 보다 다양한 활동에 대해서도 분석이 가능하다.

This study was conducted to examine dietary behaviors according to residence status and ethnicity of university students in Yanbian, China. For the subjects, 334 university students (Male=141, Female=193) answered a questionnaire about perception of weight control, dietary patterns, health habits, residence status, and ethnicity. Perception of weight, meal frequency, favorite kind of food, meal finishing time, skipping breakfast, type of breakfast, snack frequency, late-night snack frequency, exercise frequency, regular life, and sleeping time were all significantly associated with residence status. Motivation of weight control, meal frequency, regularity of meal time, meal volume, favorite kind of food, exercise time, and regular life were all significantly associated with ethnicity. University students who lived with their parents perceived their weight more properly, exhibited a more positive dietary pattern, and lived a more regular life than those students who lived in a dormitory with their friends. Chinese students exhibited a more regular dietary pattern and lived a more regular life than the Korean-Chinese students. As a result, both environmental and inherent factors are related with the dietary behaviors of university students in Yanbian, China. These data could be used to help university students in Yanbian, China attain a healthy diet.

Purpose: The purpose of this study was to evaluate the effect on blood pressure (BP) and heart rate (HR) according to aerobic exercise characteristics in adults with hypertension using a systematic review and meta-analysis. Methods: The related researches were selected from PubMed, EMBASE, Cochrane library, CINAHL, PsycINFO, SPORTDiscus and 5 domestic databases up to September 4, 2019. To estimate the effect size, random effect models were used to derive weighted mean differences (WMD) and their 95% confidence intervals (CI) of aerobic exercise on BP and HR. Results: A total of 37 RCTs with 1,813 samples were included. Aerobic exercise was found to significantly reduce systolic BP (WMD, - 8.29 mmHg; 95% CI, - 10.12 to - 6.46), diastolic BP (WMD, - 5.19 mmHg; 95% CI, - 6.24 to - 4.14) and HR (WMD, - 4.22 beats/min; 95% CI, - 5.36 to -3.09). In detail, systolic BP and diastolic BP were significantly decreased in all groups of exercise types, frequency and duration. Systolic BP and diastolic BP were significantly decreased in the moderate and vigorous-intensity group. Exercise characteristics with the most dramatical change in systolic BP were water-based training, moderate-intensity, 3 times a week and 8 to 11 weeks of duration. In diastolic BP, the greatest effect size was over 24 weeks of exercise. Conclusion: Moderate aerobic exercise, especially water-based exercise can be an important part of lifestyle modification for hypertensive patients. Also, it can be recommended in a variety of clinical settings for lowering BP and HR. However, there is insufficient evidence that low-intensity exercise is effective in lowering BP.

The purpose of the study was to identify the effects of a 12-week low-intensity exercise program on muscle strength, flexibility, balance, and cognitive characteristics related to the performance of activity of daily living(ADL). A total of 16 patients who were admitted to the medical unit of a general hospital in ChoongChung province were recruited, eight for the exercise group and eight for the comparison group. Four levels of low-intensity exercise from 'ROM on bed' to 'exercise while walking' were then applied to the exercise group according to their physical condition. During hospitalization, patients in the exercise group performed each level of the prescribed exercise with the researchers until they felt comfortable doing it independently. The researchers also visited the patients' homes after discharge to make sure they could perform the exercise with Theraband in their living environment. The exercise group was contacted by phone once a week to assess the frequency and intensity in which they performed the exercise as well as their physical condition. The subjects in the comparison group participated in measurements for the study without performing the exercise and were contacted by phone after discharge, in a matched time frame with the exercise group, to assess physical condition. Muscle strength, flexibility, balance, cognitive characteristics, and performance of ADL for the two groups were compared at the pretest and the posttest after the low-intensity exercise program by utilizing SPSSWIN and the results are as follows : 1) At the postest, measurements of muscle strengths showed that the strength of the dorsal flexor in the exercise group was significantly higher than in the comparison group. 2) Objective balance for the exercise group was significantly better than for the comparison group as measured by 'standing on one foot' and Tinetti gait and balance control. 3) The exercise group showed significantly higher task self-efficacy than the comparison group. 4) Perceived exertion for ADL for the exercise group was significantly lower than for the comparison group. 5) Improvement of performance of ADL without assistance was significantly higher for the exercise group than the comparison group. The findings suggest that a low-intensity exercise program would be useful for the elderly who show decline in their physical functioning due to hospitalization by partly improving physical strength, task self-efficacy, and performance of ADL. Directions for further research on issues of motivating people to exercise as well as of standardizing various types of exercise were discussed.

The aim of the study was to identify which fall-prevention program offered in community settings in Korea is the most effective in strengthening muscles. Muscle weakness is one of the major risk factors causing falls among the elderly. Randomized controlled trials and clinical controlled trials published between 1996 and February 2011 were included in this study. Seventeen of the 69 identified studies met the study's criteria and were included in this meta-analysis. The overall effect size of the program was .822 (95% confidence interval= .717~.927). The general strengthening exercise (1.608), dance sports training (1.538), Thera-band exercise for lower extremities (1.517), Seniorobic exercise (1.146), gait training (.959), balance training (.909), gradual resistive exercise (.888), and multifactorial fall prevention (.842) programs all show positive effects on muscle strengthening. Subgroup analyses found that more relative effects are seen in programs offered to the more elderly. In this study, the effect of increasing muscle strength on the prevention of falls can only be indirectly suggested; there are few available studies that report the frequency or history of falls in Korea. Further studies are needed to examine the direct effect of fall prevention exercise programs among the elderly.

The purpose of this study was to examine the effects of an aquarobics exercise program on the physical fitness and blood lipids in elderly women. The subjects of the study were twenty-six elderly women enrolled in an Aquarobics exercise program consisting of 60 minutes per session, 3 times a week during the period of 12 weeks. The effects of the program were assessed using the instruments to measure physical fitness and blood lipids before and after the aquarobics exercise program. Data was collected between September and December in 2006, and analyzed by frequency, paired with a t-test, using a SPSS. The results were statistically significant in muscle strength, muscle endurance, flexibility, and cardiopulmonary endurance, but no significant differences were found in agility, total cholesterol, triglycerides and high density lipoprotein cholesterol. Aquarobics exercise can be an effective nursing intervention to improve muscle strength, muscle endurance, flexibility and cardiopulmonary endurance in elderly women.
