The relationship between exercise and hone mineral density (BMD) was investigated in 153 healthy women. The BMD of lumbar spine, femur(neck, ward's triangle, trochanter) and total body was determined by dual energy X-ray absorptiometry in a group subjects(65) aged 19-59 years who had been exercising(swimming or aerobic dancing) regularly for at least 2 years as well as in a similar group of nonexercising control subjects(88). Weight, height, total lean body mass(=weight-total fat body mass-bone mineral content), animal and meat Ca, Ca index, energy expenditure, BMD, PYD/Cr were significantly higher in the exercisers than the controls. There were significantly negative correlations between age, ALP and osteocalcin and BMD, but significantly positive correlations between weight, BMI, total fat body mass and total lean body mass and BMD. Stepwise multiple regression analysis revealed that total lean body mass may be a better independent predictor to BMD than total fat body mass. The nutrient intakes were more closely related to BMD in the exercisers than the controls, but energy expenditure was more closely related to BMD in the controls than the exercisers Stepwise multiple regression analysis revealed that BMD was closely related to menopause, osteocalcin, age, weight in both groups but energy intake in the exercisers alone, energy expenditure in control alone. In premenopausal women, the exercisers had significantly greater BMD than the controls. But, in postmenopausal women, no significant difference between two groups was detected. When compared to BMD of the subjects with same age range to minimize the effect of age, aerobic dancing appears to be capable of exerting a positive effect on BMD in a group of subjects aged 19-44. However, no relationship of the swimming to BMD could be identified in a group of subjects aged 37-59. The results of this study suggest that the usefulness of exercisng appears to be significantly greater in preemenopausal women than postmenoparusal women and weight bearing activity, aerobic dancing is associated with increasing BMD at the weight bearing sites and could be beneficial in the prevention of bone loss. But the usefulness of swimming on bone should be further investgated.

Purpose: The purpose of this study is to examine the effects of a resistance band training program on body composition, physical fitness, and health promotion behavior in nursing students. Method: This study has a one-group pretest-posttest design to examine the change in body composition, physical fitness, and health-promoting lifestyle profile after participation in the resistance band training program. Training consisted of hands-based exercises using an elastic resistance band for ten weeks. Participants performed the resistance band training two days per week with a sports trainer, and 30 minutes self-training three days per week. The participants were 21 freshmen in nursing. Results: Mean age of the participants was 20.9 years, and 61.9% were not satisfied with their body shape. After the training program, muscle mass, muscular endurance, and balance of the body were significantly improved. In health promoting lifestyle profile, categories of physical activity, health responsibility, and stress management showed a significant increase. Conclusion: Results of this study suggested that exercising with a resistance band improved body composition, physical fitness, and health promoting behavior in the nursing students. We propose that resistance band training should be suitable for those who have the environment with limitation of time and space.

Vitamin E in the body system plays an important role in preventing chronic diseases by decreasing the oxidative stress by free-radicals. However, there are not enough researches on analyzing the primary factors affecting vitamin E levels in the blood in Korean adults. Therefore, the purpose of this research was to examine blood tocopherol levels and the primary factors affecting the status. A complete lifestyle survey was performed on 314 Korean adult men and surveyed their smoking, drinking and exercising habits. The average plasma level of ${\alpha}-\;and\;{\gamma}-tocopherol$ showed similar mutual relations with plasma total cholesterol (TC), triglyceride (TG), or low density lipoprotein cholesterol (LDL-C) levels (p<0.001). Plasma ${\alpha}-tocopherol$ level of the subjects did not show any difference as smoking, drinking and exercising habits changed. However, ${\gamma}-tocopherol$ per TG showed much lower figure in smokers than non smokers (p < 0.05). Amongst diet factors, plasma ${\alpha}-tocopherol$ level showed negative correlations with Vitamin E intake, while ${\gamma}-tocopherol$ level showed positive correlations with Vitamin E intake. Erythrocyte superoxide dismutase (SOD) activity and plasma tocopherol showed negative correlations, and catalase activity and plasma ${\alpha}-tocopherol$ showed positive correlationship. The level of cell DNA damage of Iymphocyte and plasma ${\alpha}-\;or\;{\gamma}-tocopherol$ showed negative correlations. As a result of this research, the factors that affect Korean adult men's plasma ${\alpha}-tocopherol$ level are plasma TG, LDL-C and cell DNA damage in Iymphocyte, while the factors that affect ${\gamma}-tocopherol$ level are plasma TG, LDL-C and vitamin E intake based on multiple regression analysis. These findings implies that the level of different types of tocopherol depends on slightly different factors. A further research is needed on the factors involved in the differentiation of the types of tocopherol.

Objectives The relationships between adolescent depression and obesity, life style has been reported, but usually study results were not consistent with the study before. This study was designed to evaluate clear relationship between obesity and depressive trends, life styles in middle school students. Methods The study participants were the 1th, 2th grade students from one middle school in Kang dong Gu, Seoul(479 Students). The participants were measured their height and weight, and they were also surveyed by questionnaire. We diagnosed the students as depressives when they scored 10 points or above on Children's Depression Inventory(CDI) of Kovacs and Beck. Results The mean depression score in the obese group was significantly higher than that of the normal body weight group, and the more severely obese the group was, the higher the depression scores for this group were. The depression score of the boys obese group was higher than the girls obese group. The depression score was significantly higher in the obese group of people who hate to do exercising, like computer games and like watching TV instead, than in the group of people who like to do exercising and don't play computer games. Conclusions This study showed that depressive mood during adolescent was related to obesity and obesity-related lifestyles.

The study aimed to analyze the lifestyles, weight control behavior, dietary habits, and depression of female university students. The subjects were 532 students from 8 universities located in 4 provinces in Korea. According to percent ideal body weight, 33 (6.4%), 181 (34.0%), 283 (53.2%), 22 (4.1%) and 13 (2.5%) were severely underweight, underweight, normal, overweight and obese, respectively, based on self-reported height and weight. As much as 64.1 % and only 2.4%, respectively, overestimated and underestimated their body weight status. Six overweight subjects were excluded from overestimation group for the purpose of this study, resulting in overestimation group consisting of only underweight and normal weight subjects. Compared to those from the normal perception group, significantly more subjects from the overestimation group were currently smoking (P=0.017) and drank more often than once a week (P=0.015), without any significant differences in dietary habits. Despite similar BMIs, subjects who overestimated their own weight statuses had significantly higher weight dissatisfaction (P= 0.000), obesity stress (P= 0.000), obsession to lose weight (P = 0.007) and depression (P = 0.018). Also, more of them wanted to lose weight (P = 0.000), checked their body weights more often than once a week (P=0.025) and had dieting experiences using 'reducing meal size' (P=0.012), 'reducing snacks' (P=0.042) and 'taking prescribed pills' (P = 0.032), and presented 'for a wider range of clothes selection' as the reason for weight loss (P = 0.039), although none was actually overweight or obese. Unlike the case with overestimating one's own weight, being overweight was associated with less drinking 0.035) and exercising more often (P=0.001) and for longer (P=0.001) and healthier reasons for weight control (P=0.002), despite no differences in frequency of weighing and depression. The results showed that weight overestimation, independent of weight status, is associated with risky lifestyles, weight control behaviors, and mental conditions. Preventive interventions should focus not only on obesity, but also on body weight overestimation.

In this paper, we propose a novel sensor system for measuring the arterial pulse in an oral cavity. In order to measure pulse wave in oral cavity, the proposed system is designed with reflection type arterial wave sensor, not by using transmission type arterial pulse wave sensor. Driving circuit through pulse current is designed for solving self-heating problem of LED. The effectiveness of the proposed sensor system is compared with pulse wave between pulse wave of oral cavity and other body parts as well as with characteristic measurements. The experiment shows that the proposed sensor system is adaptive to capturing consecutive and meaningful biometric signals through the variation of pulse wave changes in oral cavity when exercising. The study result expects to design and develop mobile sensors which could be adapted to healthcare devices.
