Purpose : It was to compare changes in respiratory function (pulmonary function, inspiratory function) after four weeks of inspiratory muscle strengthening training (diaphragmatic breathing with upper arm exercise, Power-Breathe breathing) for 36 healthy people. Methods : Subjects were randomly assigned to diaphragmatic breathing with upper arm exercise (Group I) and Power-breathe breathing (Group II) was conducted by the protocol for four weeks five times per week. As the main measurement method for comparison between groups For pulmonary function, Forced Vital Capacity (FVC) and Forced Expiratory Volume at One second (FEV1) were used, and for inspiratory function, Maximum Inspiratory Capacity (MIC), Maximum Inspiratory Pressure (MIP), and Maximum Inspiratory Flow Rate (MIFR) were used. Results : In changes in pulmonary function between groups, FVC and FEV₁ showed no significant difference, and in inspiratory function changes, MIC showed no significant difference, but in MIP and MIFR, Group B significantly improved over Group A. Conclusion : The progressive resistance training using the Power-breath device applied to the inspiratory muscle did not show a significant difference in the increase in the amount of air in the lungs and chest cage compared to the diaphragmatic breathing training accompanied by the upper arm exercise. However, by increasing the air inflow rate and pressure, it showed a more excellent effect on improving respiratory function.

The purpose of this study was to examine how combined exercise and acaiberry intake make effects on insulin and glycated hemoglobin of middle-aged women. The middle-aged women in their 40s and 50s were classified into three groups - group A which only had acaiberry intake, group B which both had acaiberry intake and combined exercise, and group C which only underwent the combined exercise. The combined exercise was held three times a week for 8 weeks, each for 60 minutes including warming up and cooling down. The aerobic exercise was carried out for 20 minutes with a treadmill walk with HRmax 50-60% and the resistance movement was carried out for 20 minutes with a strength of 50-60% based on 1RM. The participants were told to have the acaiberry drink before breakfast and dinner, by melting 5g of acaiberry powder to water. 2-way RGRM ANOVA was carried out to process the data for comparing each groups. In conclusion, the 8-weeks of combined exercise and acaiberry ingestion therapy did not improve the insulin and glycated hemoglobin. It is more likely to show clear changes in both elements with longer treatments and controlling the amount of ingestion and exercise intensity.

This paper proposes a customized AI exercise recommendation service for balancing the relative amount of exercise according to the working environment by each occupation. WISDM database is collected by using acceleration and gyro sensors, and is a dataset that classifies physical activities into 18 categories. Our system recommends a adaptive exercise using the analyzed activity type after classifying 18 physical activities into 3 physical activities types such as whole body, upper body and lower body. 1 Dimensional convolutional neural network is used for classifying a physical activity in this paper. Proposed model is composed of a convolution blocks in which 1D convolution layers with a various sized kernel are connected in parallel. Convolution blocks can extract a detailed local features of input pattern effectively that can be extracted from deep neural network models, as applying multi 1D convolution layers to input pattern. To evaluate performance of the proposed neural network model, as a result of comparing the previous recurrent neural network, our method showed a remarkable 98.4% accuracy.

This study was carried out to verify the accuracy of fitness tracking devices in monitoring heart rate and energy consumption and to contribute to the development of a forest exercise program that can recommend the intensity and amount of forest exercises based on personal health-related data and provide monitoring and feedback on forest exercises. Among several commercially available wearable devices, Fitbit was selected for the research, as it provides Open API and data collected by Fitbit can be utilized by third parties to develop programs. Fitbit provides users with various information collected during forest exercises including exercise time and distance, heart rate, energy consumption, as well as the altitude and slope of forests collected by GPS. However, in order to verify the usability of the heart rate and energy consumption data collected by Fitbit in forest, the accuracy of heart rate and energy consumption were verified by comparing the data collected by Fitbit and reference. In this study, 13 middle-aged women were participated, and it was found that the heart rate measured by Fitbit showed a very low error rate and high correlation with that measured by the reference. The energy consumption measured by Fitbit was not significantly different from that measured in the reference, but the error rate was slightly higher. However, there was high correlation between the results measured by Fibit and the reference, therefore, it can be concluded that Fitbit can be utilized in developing actual forest exercise programs.

Weight reducing methods were surveyed by questionnares in March through May, 1998 with 641 women living in Inchon to provide the information for the education of proper weight control. Methods that they have used for weight-reduction were exercise (33.1%), diet therapy(29.6%), sauna(7.3%), ingestion of special food(4.8%), administration of drugs(4.0%) and herb-medicines. The respondents considered exercise(38.4%) and diet therapy(31.5%) as the most effective methods in reducing weight and the response was different with ages at p<0.01. They have practiced the diet therapy by reducing the amount of food(27.7%), skipping one or two meals a day (20.8%), avoiding high calorie snacks(8.8%) and regulating food items in a meal(3.8%). Exercises which they have done were walking(48.0%), aerobics(2.3%), swimming(23%) and using the health instruments(6.7%). Their choices in kinds of exercises were significantly dependent upon ages, marriage and their occupation(P<0.01). Acupuncture(38.0%) was the most frequently used oriental medicine therapy and original drugs(32.2% ) and moxibustion(22.0%) were also used. The women have taken drugs was 9.5%. Among them cream-typed cosmetics(41%), weight reducing drugs(30%), diuretics(18% ), and smoking(7%) were used. Fifty respondents out of 641 had expericences to have special food therapy such as grape, apples and vinegar(42%) and enzymes(18%) for some period of time.

This study was done to investigate effects of smoking, drinking and exercise on body composition, dietary intakes, serum lipids of male high school students in Seoul. Body Composition was analyzed by the Bioelectrical Impedance Fatness Analyzer. Dietary survey was conducted by 24-hour recall method and nutrient intakes were analyzed by the Computer Aided Nutritional analysis program for professional (CAN-Pro). All data were statistically analyzed by SAS PC package program. Mean and standard error were examined for each items. The significant difference was examined by student's t-test. Body composition data showed that protein mass, mineral mass and lean body mass of regular exercisers were significantly higher (p < 0.05) than those of irregular exercisers. Energy and protein intakes of male high school students were 1868 kcal/day (69.2% RDA), 68 g/day (91.3% RDA), respectively. Ca, Fe and Vitamin B$_2$ intakes were lower than 2000 RDA. Analysis of serum lipids showed that serum levels of HDL-cholesterol of drinkers were significantly higher (p < 0.05) than those of nondrinkers. Overall results imply that smoking and alcohol drinking of adolescent males may not much influence on serum lipids levels because pack-years of smoking or the amount of alcohol drinking was not serious enough to be harmful to health.

The dietary habits and eating behaviors of nonagenarian subjects over 90 years old in Korean representative longevity belts of Damyang, Gokseong, Kurye, Sunchang were evaluated. The subjects of the study were 91 elderly people (26 males and 65 females) over 90 years old and their dietary habits, food preferences and meal patterns were collected by individual interview. The percentage of subjects, who answered 'very good' or 'good' for their health status, was $65.9\%$. In this study, $55\%$ of subjects were without chronic diseases, and there was no significance difference in gender. Many subjects had performed regular exercise and outdoor activity. The rate of eating together with their family was $79.1\%$. Most of subjects ($91.2\%$) had a regular mealtime consuming three meals a day, and they had good appetite and pleasure of eating. The higher preference of food group was fruits ($95.6\%$), legumes ($94.5\%$), mushrooms ($93.4\%$) and vegetables ($92.3\%$), but the amount of intakes is higher in vegetables than the others. Eating with family, regular exercise and self-rated good health are improved their nutrient intakes. Most frequently consumed meal pattern was rice plus soup and side dishes. The side dish consumed frequently was Namul (blanch and seasoned vegetables). From this study, the nonagenarian populations in longevity belt in Korea have good dietary habits such as regular mealtime, constant amount of meal and eat with pleasure. They are taking Korean traditional meal pattern, providing enriched antioxidant vegetable foods. Also, it can be concluded that the amount and quality of diet in the long-lived elderly are responsible for the Korean traditional family system.

Background: There is abundance of studies on the decrease in body fat through limited calorie intake or exercise; however, studies focusing simultaneously on functional foods and exercise are rare. This study was aimed to identify the effects of combination of a functional beverage and exercise on body composition and biochemical metabolic profiles. Method: Eighty-one healthy volunteers (69 females aged 19 to 50 years and 12 males aged 19 to 55 years), who maintained their body weight stable with 23 or higher in BMI (kg/$m^2$) and 25% or higher body fat for the last three months, were recruited in the study through written advertisement. All the subjects gave their informed consent, and the study was conducted in accordance with the Declaration of Helsinki. The study design was a randomized double-blind placebo-controlled parallel group design. All participants were given 12-week programed-exercise, which was performed 3 times a week. One bottle (100 ml) of test (Garcinia cambogia 300 mg, L-carnitine 20 mg, Soy peptide 1,000 mg) or placebo solution was given daily 30 min before each session of programed-exercise. BMI (body mass index), %fat, local fat amount (visceral and mid-thigh), waist circumference, skin fold thickness and some biochemical metabolic parameters like glucose, insulin and free fatty acids, etc in the blood were measured and compared before and after 12-week intervention within groups as well as between groups according to the protocol Results: Twenty six volunteers were dropped out and fifty five volunteers completed the study. At the end of 4, 8, and 12 weeks, approximately 1.98%, 3.00% and 3.50% losses of initial body weight were observed, respectively, in the test group (P<0.01), and 0.29, % ,0.74%, 1.60%, respectively, in the placebo group (P>0.05). BMI changed by 2.40%, 3.41% and 4.46%, respectively, in the test group, and 0.38%, 0.95% and 1.75%, respectively, in the placebo group, at each period of time. The reductions of body weight and BMI were significantly higher in the test group than in the placebo group at each period of time (P<0.05). Conclusions: It is thought that the combination of functional beverage, which contains mostly garcinia cambogia, L-carnitine, and soy peptide, and exercise have synergy effects on reducing body fat.
