Effect of exercise performance by elderly women on balance ability and muscle function.

[Purpose] The aim of this study was to investigate the effect of an exercise intervention on the balance ability and muscle function of elderly women. [Subjects] The subjects were randomly divided into a control group (n=10) and an exercise group (n=10). [Methods] The subjects participated in an elastic band exercise program lasting for 8 weeks, exercising for 40 minutes, four days a week with resting terms of 60 sec. Subjects used a band corresponding to 60% of the strength of the color band with which repetitive exercise was possible up to twelve times. The subjects performed elastic band exercises, with variations to the number of band exercises according to the improvement of their physical fitness levels. When fifteen repetitive elastic band exercises could be performed with no damage of the body, we changed the band for one which was one level up from the former one and subjects used the same band for the upper body and lower body. [Results] Leg muscular strength measured as sit-stand repetitions in 30 s significantly increased in the exercise group after the intervention compared to before the intervention. Leg muscular endurance measured as the number of knee ups in 2 minutes significantly increased in the exercise group after the intervention compared to before the intervention. Balance measured by one-leg standing time with the eyes open significantly improved in the exercise group after the intervention compared to before the intervention. [Conclusion] Balance ability and muscle function significantly improved in the exercise group and showing that the intervention is effective at improving balance, muscle strength, and muscle endurance of elderly women.

The data collection involved using 119 rescue daily reports, cardiopulmonary arrest patients emergency treatment detail reports and 119 paramedics survival data. In conclusion, 119 rescues interventions in the patients with pre-hospital cardiac arrest have significantly increased survival rates. 119 rescues interventions included early defibrillation, oxygen supply, airway open, and intravenous access affected significantly survival rate. Therefore there is need to increase 119 rescues interventions performance to improve survival rate of cardiac arrest patients.

The Effects of Exercise Therapy on CVD Risk Factors in Women.

[Purpose] The purpose of this study was to search for the association of Type D personality and CVD risk factors through comparison of the association of exercise participation with CVD risk factors in women. [Subjects] The research subjects were randomly assigned to four groups: Type D+Exercise (n=12), Type D+non-exercise (n=12), non-Type D+Exercise (n=12), and non-Type D+non-exercise (n=10). The study consisted of 46 participants. [Methods] An aerobic exercise program and meditation were conducted in parallel for 10 months. Stretching was performed for 10 min as a warm-up, and then walking and running on a treadmill at 60 to 70% of HRmax were performed for 40 min three times a week. Blood samples were processed according to standard laboratory procedures. The concentrations of TG and HDL cholesterol were determined enzymatically using a clinical chemistry analyzer (Hitachi High-Technologies Corporation, Tokyo, Japan). [Results] The weight, percentage of body fat, waist circumference, triglyceride concentration, HDL cholesterol concentration, systolic blood pressure, and diastolic blood pressure showed a significant difference between measurement times in the exercise groups. [Conclusion] In conclusion, there were significant differences between groups in terms of cardiovascular disease risk factors.

Effects of horseback riding exercise therapy on hormone levels in elderly persons.

[Purpose] The purpose of this study was to investigate the effect of riding exercise on hormone levels in normal elderly people who were taught horseback riding for 8 weeks. [Subjects] Subjects were classified into an exercise group (n=10) and control group (n=10). [Methods] The two groups, horseback riding exercise group of 10 and control group of 10, were each tested for 15 minutes, 3 times, over 8 weeks. Post-exercise tests were implemented in both groups in the same way as pre-study tests. [Results] The horseback riding group showed a significant difference in the pre- and post-exercise serotonin and cortisol levels. Additionally, serotonin and cortisol levels showed significant differences between the two groups. [Conclusion] Serotonin and cortisol levels significantly increased in the experimental group, suggesting that horseback riding exercise is effective for improving the levels of these hormones.

Effects of horseback riding exercise therapy on background electroencephalograms of elderly people.

[Purpose] This study investigated the effect of horseback riding exercise on the background electroencephalograms of elderly people who performed horseback riding for 8 weeks. [Subjects] Twenty elderly people were divided into the horseback riding exercise and control group (n = 10 each). [Methods] The exercise was performed for 15 minutes, 3 times per week for 8 weeks. Electroencephalograms were analyzed. Post-exercise evaluation was performed after 8 weeks. [Results] After the horseback riding exercise, the relative slower alpha power index was active in the T3 and P4 domains but suppressed in the Fp1, Fp2, F3, F4, T4, and P3 domains. Moreover, the relative faster alpha power index was active in all domains of the horseback riding exercise group but was suppressed in all domains of the control group. There was a significant difference between groups in the F3 domain. [Conclusion] The alpha power index increased significantly after horseback riding exercise, suggesting the exercise improved background electroencephalogram.

Comparison of the Effects of Exercise Participation on Psychosocial Risk Factors and Cardiovascular Disease in Women

[Purpose] The aim of this study was to research the association of Type D personality with CVD risk factors and psychology through comparison of the association of exercise participation with CVD risk factors and psychological risk factors in women with Type D. [Subjects] This study included 416 middle-aged women. All participants completed the 14-item Type D Scale (DS14) to assess Type D personality. The DS14 consists of two subscales, NA and SI, both of which comprise 7 items. The research subjects were randomly assigned to four groups: Type D+Exercise (n=12), Type D+non-Exercise (n=12), non-Type D+Exercise (n=12), non-Type D+non-Exercise (n=10). The study consisted of 46 participants. [Methods] An aerobic exercise program and meditation were conducted in parallel for 10 months. Stretching was performed for 10 min as a warm-up, and then walking and running were performed on a treadmill at the HRmax 60–70% level for 40 min; this was done three times a week. Blood samples were processed according to standard laboratory procedures. The concentrations of TG and HDL-cholesterol were determined enzymatically on a clinical chemistry analyzer. Blood glucose was measured by the hexokinase method. [Results] Weight, percent fat, social support, and waist circumference showed a significant difference between times in the Exercise groups, and the values were significantly lower than those of the non-Exercise groups. Anxiety and depression showed a significant interaction effect between groups. The average number of CVD risk factors in subjects showed a significant difference between groups. [Conclusion] In conclusion, there were significant differences between groups in terms of CVD risk factors and psychological risk factors in women with Type D personality.

Effects of therapeutic recreation on the brain quotient in the elderly dementia patients

[Purpose] This study investigated how participation in a recreation program influences electroencephalogram changes in the demented elderly. [Subjects] Fourteen patients were included in the experimental group and 18 in the control group. [Methods] They had no regular exercise habits, and walked independently, and scored 11–23 points on the Mini-Mental State Examination, and thus had no apraxia and could communicate. To empirically verify changes in electroencephalograms of the demented elderly for depression, sleep disorder, and life quality through their participation in the therapeutic recreation program, male and female citizens >65 years old at a geriatric hospital were included. The experimental group attended therapeutic recreation programs regularly for 3 months and control group did not. [Results] Electroencephalogram values were higher in the experimental than in the control group, demonstrating that the therapeutic recreation program enhances electroencephalogram values. However, post-program electroencephalograms between the two groups showed minor differences for all variables, except for the anti-stress index and brain quotient. [Conclusion] The therapeutic recreation program caused changes in brain activation, and this method revealed the relation between the activity program and emotion via the anti-stress index.

[Results] The results demonstrate that the subjects who performed sittercise had significantly decreased depression levels compared to the control. They also reported significantly improved sleep quality. [Conclusion] A favorable change in depression levels was seen after sittercise which alse had a significant effect on sleep quality.

Effects of endurance exercise on mitochondrial function in mice.

[Purpose] The purpose of this study was to investigate the effects of 8 weeks of endurance exercise on the cardiac mitochondrial function of mice. [Subjects] Ten 129 SvJ/C57BL6 Male mice were used. The mice were randomly divided into an exercise group (n=5; mean ± SD weight, 27.4 ± 1.6 g) and a control (n=5; mean ± SD weight, 28.2 ± 1.1 g). The exercise mice ran on a motor driven treadmill 5 days per week for 30 minutes at a speed of 24 m/min for 8 weeks. Mitochondrial function as measured RCI was compared between the exercise and control group mice using an independent t test. [Results] The exercise mice had a significantly greater state 4 respiration than to the sedentary control mice. There was also a significant difference in RCI between exercise and sedentary control mice. [Conclusion] Endurance exercise decreased RCI, indicating an uncoupling of respiration and oxidative phosphorylation.

The Analysis of Acute Drug Intoxication in Emergency Medical Center

Abstract In order to investigate acute drug intoxication trends in the elderly who visited emergency medical center, Data were collected from the records of poisoning patients visited five different hospitals from January 1, 2007 to December 31, 2007. The analysis was conducted by using 624 cases from these hospitals. The results are as follows. The study was designed to be divided into two categories of elderly and those under age 65. The criteria were as follows ; male to female ratio, those living together with families, past suicide attempts, acute drug intoxication reasons, management, mental status and the level of sobriety on arrival at the medical centers, and monthly distribution. There was no difference between two groups. In conclusion, it is necessary to develop suicide prevention program for the suicide vulnerable group. Accidental poisonings are going to continue. This means that poisoning prevention education programs must also be developed for periodic use. Key Words : Drug intoxication, Emergency medical center, Suicide
