Objective: The aim of this study was to measure the muscle architectural parameters of abdominal muscles in healthy individuals by rehabilitative ultrasound imaging (RUSI) and to investigate their changes after bridging exercise in various environments. Design: Cross-sectional study. Methods: The study included 40 healthy participants (19 men, 21 women). Subjects were randomly allocated to a stable surface group (SG, n=20) or an unstable surface group (UG, n=20). The participants assumed three positions in rest, bridging exercise with knee flexion $60^{\circ}$, and bridging exercise with knee flexion $90^{\circ}$ for the measurement of abdominal muscle thickness by RUSI. For the resting position, the participants held the head neutral in a hook-lying position and the dominant side was measured. For contraction, the participants performed the bridging exercise with the knee joint in $60^{\circ}$ and $90^{\circ}$ of flexion for 10 seconds each. Results: For transversus abdominis, external oblique muscle thickness, within the stable surface group and the unstable surface group, no significant contraction difference was observed in both the $60^{\circ}$ and $90^{\circ}$ bridge exercise conditions. Contraction difference of internal oblique muscle was significantly larger at $90^{\circ}$ than at $60^{\circ}$ within the SG (p<0.05). But within the UG, no significant contraction difference was shown. There was no significant contraction difference between the surface group and the unstable SG at $60^{\circ}$ condition and at $90^{\circ}$ condition in all measured muscles. Conclusions: The contraction difference is different for each muscle during bridge exercise with knee flexion $60^{\circ}$ and bridging exercise with knee flexion $90^{\circ}$. Muscle contraction difference is generally large when exercised on an unstable surface than a stable surface, but these are not statistically significant when bridging exercise is performed using dynamic air cushion for unstable surface.

Purpose: The purpose of this study was (1) to examine the effects of a Health Promotion Exercise Program (HPEP) on functional improvement, physical strength (PS) and muscle activation (MA), and the interactive influence with activities of daily living (ADL) and instrumental activities of daily living (IDAL) in the elderly, and (2) to develop and provide a HPEP for the elderly in order to prevent declines and impairments in integrated nerve function and physical capacity. Methods: Our study included relatively healthy elderly people aged 65 years or older. The experimental group, which was composed of 30 people, participated in a HPEP 50~60 minutes a day, 3 times a week, for a total of 12 weeks. Results: Confirmatory factor analysis (CFA) validated the measurement models for MA, physical strength, ADL and IADL with a p<0.01. This confirms (i) the beneficial effects of the ADFP on their MA and PS, and (ii) that their improvement in PS, in turn, can improve their IADL. The results of this study indicates that ADFP can help Korean seniors 65 years or older improve their MA, PS, ADL, and IADL, and do so synergistically. Conclusion: An HPEP, when organized in such a way that the elderly can easily do it, and when exercise items and intensity can be programmed and reorganized accordingly to individual physical and physiological characteristics by presenting 5 categorized health domains of physical strength, may be useful, especially because it can be practiced irrespective of time and place.

Objective: Prone bridge exercise is one of the core strengthening exercise for improving abdominal, lower and upper extremity muscles. In addition, coactivation of the trunk muscles and extremities is important for treatment of low back pain. This study aimed to investigate the correlation between the thickness, cross-sectional area of the target muscle, and endurance during prone bridge exercise. Our hypothesis was that an increase in muscle thickness is positively related to the hold time for the static prone bridge exercise. Design: Cross-sectional study. Methods: Fourteen healthy university students (8 men and 6 women) voluntarily participated in the study at Sahmyook University. Hold time for the prone bridge with one and both legs was measured. The resting and contracted thickness of the lateral abdominal, rectus femoris, and triceps muscles was measured using rehabilitative ultrasound imaging. The correlation between muscle thickness and endurance for maintenance time was evaluated. Results: The prone bridge with both legs and the contraction thickness of the triceps muscle showed a positive correlation (r=0.692, p<0.05); the prone bridge with one leg and the contraction thickness of the internal oblique and transversus abdominis muscles showed a positive correlation (r=0.545, 0.574, p<0.05, 0.05, respectively). Conclusions: Endurance for the prone bridge exercise with a stable support surface is correlated with the contraction thickness of arm muscles; the prone bridge exercise with an unstable support surface is correlated with the contraction thickness of the deep abdominal muscles.

This study examined the effect of job stress and mental health factors on the oral symptoms of caring service workers in Seoul. For the research method, a survey was conducted from July 24 to August 6, targeting 150 caring service workers. The survey items were job stress, mental health (physical symptoms, anxiety, and insomnia), and self-diagnosed oral symptoms. The results of the study were as follows. Job stress (p=0.001) had a significant effect on the oral symptoms. In addition, physical symptoms (p<0.001), anxiety symptoms (p<0.001), and insomnia symptoms (p<0.001) all had significant effects on the oral symptoms. Among the risk factors, physical symptoms had the greatest influence on oral symptoms. In addition, according to the correlation result of job stress, anxiety symptoms, insomnia symptoms, oral symptoms, as job stress increases, physical symptoms (p<0.001), anxiety symptoms (p<0.001), insomnia symptoms (p<0.001), oral symptoms (p<0.01) showed an increasing positive correlation and a statistically significant difference. Physical and psychological labor power is greatly exhausted by care service workers performing tasks that require physical and mental care for those who are being cared for. Therefore, there is a need for systematic expansion measures for the mental health of workers and the introduction of customized oral health education programs to improve oral health because improved health and oral health conditions can increase work performance.

Intellectual disability affects all spheres of the lives of people can be who suffer from it. Unfortunately, modern medicine cannot cure intellectual disability. However, the quality of life improved by means of physical exercise. In this study, we compared the health-related physical fitness, metabolic syndrome index and mental health between a game biking group(5 participants) and a brisk walking group(4 participants). This study used a between-subject design and verified by non-parametric test. The participants performed an exercise program with warm up and resistance training for 12 weeks. A game bike was used for the physically impaired, where the individual looked at a screen and pedaled. The fasters he pedaled the faster the object on the screen movies. We measured health-related physical fitness, metabolic syndrome index and mental health. We also measured their perceived exertion and interest during the exercise by a visual analog scale. The results before and after the exercise program showed that health-related physical fitness, metabolic risk factors, mental health level were improved in both groups. As we hypothesized before the study, the game biking group showed a statistically significantly different level on the Rating of Perceived Exertion than the brisk walking group and a higher level on the Rating of Exercise Interest during the exercise program. Our results lead to a conclusion that an exercise program with the use of a game bike improve motivation for exercise participation in intellectually handicapped participants.

The purpose of this study was to investigate the influences of adolescents on self-rated health and happiness, physical activity, and mental health according to time of smartphone use. The researcher used raw data from the Korea youth risk-behavior web-based survey(2017). A total of 64,991 adolescents were enrolled and 54,603 were analyzed in logistic regression analysis. The researcher set gender, self-rated health and happiness, physical activity, and mental health as independent variables and performed logistic regression analysis with smartphone overuse time as dependent variables. As a result, the female had a smartphone overuse of 1.49 to 1.67 times higher than male. Subjectively healthy people were 1.2 to 1.35 times more likely to use smartphones than those who did not(p<.001). People with higher physical activity were higher by 1.17 to 1.18 times than people without physical activity(p<.001). Subjective happiness did not predict smartphone usage(p>.05). People with subjective stress were higher 1.13 to 1.22 times than people without stress, and person with sadness and despair and suicide plan, 1.37 to 1.54 times, 1.17 to 1.24 times than those who did not(p<.001). Depression tended to become more serious as smartphone use increased. These investigation suggest that the self-rated health, physical activity, and mental health excluding self-rated happiness are related to overuse of smartphone.

Purpose: The purpose of this study was to develop a multi-disciplinary self-management intervention based on empowerment theory and to evaluate the effectiveness of the intervention for older adults with chronic illness. Methods: A randomized controlled trial design was used with 43 Korean older adults with chronic illness (Experimental group=22, Control group=21). The intervention consisted of two phases: (1) 8-week multi-disciplinary, team guided, group-based health education, exercise session, and individual empowerment counseling, (2) 16-week self-help group activities including weekly exercise and group discussion to maintain acquired self-management skills and problem-solving skills. Baseline, 8-week, and 24-week assessments measured health empowerment, exercise self-efficacy, physical activity, and physical function. Results: Health empowerment, physical activity, and physical function in the experimental group increased significantly compared to the control group over time. Exercise self-efficacy significantly increased in experimental group over time but there was no significant difference between the two groups. Conclusion: The self-management program based on empowerment theory improved health empowerment, physical activity, and physical function in older adults. The study finding suggests that a health empowerment strategy may be an effective approach for older adults with multiple chronic illnesses in terms of achieving a sense of control over their chronic illness and actively engaging self-management.

The purpose of this study was to determine if there were any beneficial effects of massage or microwave diathermy regarding delayed onset muscle soreness (DOMS) and indices of muscle damage. Twenty-one adult women, randomly divided in two treatment groups and a control group, performed eccentric stepping exercise with the quadriceps until exhaustion. The treatment groups additionally performed massage or microwave diathermy after the stepping exercise. Pressure pain threshold measure for DOMS and muscle enzymes in the blood were obtained before, and 0, 24, 48 and 72 hours after exercise. The results were as follows; 1. Eccentric exercise caused DOMS and elevations of muscle enzymes in the blood, with peak values exercise levels by 24 hours after exercise and GOT and CRP by 72 hours after exercise. DOMS and CK activity remained elevated 72 hours after exercise. 2. DOMS and blood muscle enzymes response to eccentric exercise were reduces by massage or micro diathermy therapy. DOMS was significantly decreased at 72 hours after exercise by massage and microwave diathermy. CK activity was significantly decreased at 72 hours after exercise by microwave diathermy. There was the significant reduction in LDH at 48 hours, GOT at 24, 48, 72 hours. and CRP at 24, 48 hours after exercise by massage and microwave diathermy. These results indicate that massage or microwave diathermy is had effect on recovery from exercise-induced muscle damage. In our's suggestion. microwave diathermy is particularly more appropriate therapeutic modality because it is more simple and economic than massage.
