Conventional physical activity monitoring systems, which use accelerometers, global positioning system (GPS), heartbeats, or body temperature information, showed limited performances due to their own restrictions on measurement environment and measurable activity types. To overcome these limitations, we developed a portable exercise analysis system that can analyze aerobic exercises as well as isotonic exercises. For bioelectric signal acquisition during exercise, waist belt with two body contact electrodes was used. For exercise analysis, the measured signals were firstly divided into two signal groups with different frequency ranges which can represent respiration related signal and muscular motion related signal, respectively. After then, power values, differential of power values, and median frequency values were selected for feature values. Selected features were used as inputs of support vector machine (SVM) to classify the exercise types. For verification of statistical significance, ANOVA and multiple comparison test were performed. The experimental results showed 100% accuracy for classification of aerobic exercise and isotonic resistance exercise. Also, classification of aerobic exercise, isotonic resistance exercise, and hybrid types of exercise revealed 92.7% of accuracy.

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.
