        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.

        The objective of this research was to examine the effects of lumber stabilization exercise and a general physiotherapy program for caregivers with chronic low back pain. Sixteen people participated in this study and were randomly assigned to two groups for either lumbar stabilization exercise or for general physiotherapy, respectively. The experiment was performed for eight weeks. To examine the general as well as the medical characteristics of the participants, the following measurements were used: Visual Analogue Scale (VAS); Oswestry Disability Index (ODI); Back Performance Scale (BPS); Roland - Morris Disability Questionnaire (RMDQ); and Beck Depression Index (BDI). To compare the general and medical characteristics of the participants in the two groups, an independent t test were used. During the experiment, a paired t test was conducted to determine whether there was a significant difference in the values of VAS, ODI, BPS, RMDQ, and BDI before and after the experiment. To examine the difference in the VAS, ODI, BPS, RMDQ, and BDI values in the two groups, ANCOVA was used with pre test values as a covariate. According to the test results, in the lumbar stabilization exercise group, the VAS, ODI, BPS, RMDQ, and BDI values showed a statistically significant difference before and after the test (p<.05). In comparison, in the general physiotherapy program group, only the ODI and BPS values showed a statistically significant level of improvement. Regarding the degree of improvement, participants in the lumbar stabilization exercise group showed statistically significant progress compared to those in the general physiotherapy group. In summary, lumbar stabilization exercise is regarded as more effective than general physiotherapy for treating caregivers with chronic low back pain. In future studies, it will be useful to expand the research and to examine the long term effects of lumbar stabilization exercise on workers.

        This study was to examine on the respiratory variables, heart rate and muscle activity between the static recovery and dynamic recovery after progressive resistance exercise to maximal point. Subjects were 15 students enrolled in N University. All were tested two times (static recovery and dynamic recovery) and were requested to perform a walking on a treadmill after progressive resistance exercise to maximal point. Electromyography(EMG) was used to monitor the muscle activity(TA: Tibialis Anterior, MG: Medial Gastrocnemius) during gait. CPEX-1 was used to measure the respiratory variables and heart rate. The dynamic recovery group was shown the significant lower heart rate than that of static recovery group at during gait. Respiratory rate showed statistically a significant difference. Electromyography(RMS, root mean square) showed a non-significant difference. But the dynamic recovery group of muscle activity was found highly in TA and MG. This study indicated that the dynamic recovery method evidenced more faster than the static recovery method. And this type of dynamic rest by walking can be a help of recovery after exercise.

        The aim of this study was to compare electromyography activity for long and lateral heads of triceps brachii muscle according to forearm positions during different triceps strengthening exercises. The muscle activities for long and lateral head of triceps brachii were measured by surface electromyography. Fifteen healthy volunteers participated for this study and performed elbow extension in three different elbow extension exercises (elbow extension in a supine position; EES, elbow extension with shoulder abduction at 90 degrees in a prone position; EESA, and elbow extension with one arm at the side of the trunk in a prone position; EESP) and forearm positions (supination, neutral, and pronation). A two-way repeated measures ANOVA was used to compare the effects of the exercise positions and forearm positions. The EMG activities of the long head of the triceps brachii increased significantly during EESP with forearm supination, whereas the activity of the lateral head of the triceps brachii increased significantly during EESA with the forearm in a neutral position (p<.05). The results of this study suggest that exercise positions and forearm positions should be considered for selectively strengthening the long and lateral heads of triceps brachii muscles.

        This study was to investigate the positive effects of specially designed trunk-stabilization exercise program on lower extremity balance of elderly with history of leprosy. In this participants, lower extremity functions has been undermined by the development of damage in peripheral nerves. A total of 40 elderly with history of leprosy were divided into 2 groups of equal size (): a group that participated in the exercise program, and a control group that did not exercise but did continue to engage in normal daily activities (including walking). The exercise group exercised for 60 minutes 2 days a week for 12 weeks. Static balance ability was measured by asking study participants to a one leg standing test: dynamic balancing ability was measured with a tandem walking test and a timed up-and-go test. The participants in the exercise program and the control group were tested before and after completion of the exercise program for comparison, and then divided according to their ability to feel sensory in the soles of their feet into the categories of normal sensory group: group with sensory loss in one foot: and group with sensory loss in both feet. The participants in the exercise program showed a positive, statistically significant difference in static balance compared with the control group (p<.05) as measured using the one leg standing test. Similarly, the participants in dynamic balance (p<.05) as measured using the tandem walking and timed up-and-go tests. Finally, these improvements were related to the severity of sensory loss in the soles of the feet for all study participants.

        The purpose of this study was to assess visual biofeedback's influence on trunk muscles' (EMG) activity and endurance holding time for correct position during whole-body tilt exercise. For the study, we recruited 14 volunteers who showed no symptom of lumbar disease during medical tests. We measured the EMG activity of their rectus abdominis, external abdominal oblique, internal abdominal oblique and erector spinae muscles, and their endurance holding time for correct position during anterior and posterior whole-body tilt under two conditions: whole-body tilt with and without visual biofeedback. Resistance with gravitational force on the trunk during whole-body tilt was applied by using a device that had a monitor on which the subjects could check their alignment and that sounded an alarm if a subject's alignment collapsed. The study showed an increase in the EMG activity of external abdominal oblique, internal abdominal oblique/rectus abdominis ratio and endurance holding time for correct position during both anterior and posterior whole-body tilt with visual biofeedback compared with without visual biofeedback (p<.05). We suggest that the whole-body tilt exercise with visual biofeedback could be a beneficial strategy for selectively strengthening the internal abdominal oblique muscle and minimizing the rectus abdominis muscle's activity while maintaining correct alignment during whole-body tilt exercise.

        The purpose of this study was to compare the trunk and lower extremity muscle activity induced by six different conditions floor, intensity 0, 1, 3, 5 of whole body vibration (WBV), and Swiss ball during bridging exercise. Surface electromyography (EMG) was used to measure trunk and lower extremity muscles activity. Ten elderly women were recruited from Hong-sung Senior Citizen Welfare Center. The collected EMG data were normalized using reference contraction (during floor bridging) and expressed as a percentage of reference voluntary contraction (%RVC). To analyze the differences in EMG data, the repeated one-way analysis of variance was used. A Bonferroni's correction was used for multiple comparisons. The study showed that EMG activity of the rectus abdominis, external oblique, internal oblique, erector spinae and rectus abdominis muscles were not significantly different between six different conditions of during bridging exercise (p>.05). However, there were significantly increased EMG activity of the rectus femoris (p=.034) in the WBV intensity 0, 1, 3, and 5 conditions compared with the floor bridging condition. EMG activity of the medial gastrocnemius were significantly increased in the WBV intensity 0, 1, 3, 5 and Swiss ball conditions compared with the floor bridging condition. Future studies are required the dynamic instability condition such as one leg lifting in bridging.

        The purpose of this study was to compare the effects of treadmill walking in underwater and overground which affects gait and physical function of people who have had a stroke. Twenty people after a stroke who have become hemiplegic over 6 months were participated. Participants were divided into two groups: underwater treadmill group(UTG) and overground treadmill group(OTG). The intervention was done 4 times per weeks for 6 weeks and 1 session lasted for 30 minutes. Gait and physical function elements were measured at baseline, at the middle(3 weeks) and at the end of the intervention(6 weeks). For the elements of gait, walking velocity, affected stance phase, affected weight bearing were assessed. For the elements of physical function, Short Form 8(SF-8) health survey was used. The result of this study showed that both groups improved similarly in walking velocity. However participants in UTG improved more than those in OTG in affected stance phase(p<.05), affected weight bearing( p<.05) and emotional aspect(p<.001). Based on the results of this study, it can be suggested that treadmill walking both in underwater and on the ground can be effective in improving hemiplegic gait and physical function of people who have had a stroke. The result also suggest that the underwater treadmill exercise can be more effective than overground treadmill in restoration of gait in people after stroke.

        This study is intended to examine the motor skill learning and treadmill exercise on motor performance and synaptic plasticity in the cerebellar injured rats by harmaline. Experiment groups were divided into four groups and assigned 15 rats to each group. GroupⅠ was a normal control group(induced by saline); GroupⅡ was a experimental control group(cerebellar injured by harmaline); GroupⅢ was a group of motor skill learning after cerebellar injured by harmaline; GroupⅣ was a group of treadmill exercise after cerebellar injured by harmaline. In motor performance test, the outcome of groupⅡ was significantly lower than the groupⅢ, Ⅳ(especially groupⅢ)(p<.001). In histological finding, the experimental groups were destroy of dendrities and nucleus of cerebellar neurons. GroupⅢ, Ⅳ were decreased in degeneration of cerebellar neurons(especially groupⅢ). In immunohistochemistric response of synaptophysin in cerebellar cortex, experimental groups were decreased than groupⅠ. GroupⅢ's expression of synaptophysin was more increased than groupⅡ, Ⅳ. In electron microscopy finding, the experimental groups were degenerated of Purkinje cell. These result suggest that improved motor performance by motor skill learning after harmaline induced is associated with dynamically altered expression of synaptophysin in cerebellar cortex and that is related with synaptic plasticity.

        Breast cancer is the most frequently diagnosed cancer primarily affecting women and negatively impacting the individuals, families, and the health care system. Despite the well-known benefits of exercise for breast cancer survivors, rate of physical activity declines during adjuvant therapy and may not return to pre-diagnosis levels. In addition, low levels of adherence to exercise have been observed in this cohort. The challenge is to identify strategies that are effective in promoting exercise adherence. Several of the studies use social cognitive theory as a theoretical framework to design exercise interventions that encourage adherence. Within and without this framework, they have implemented interventions within the home and gym-based environments. Strategies used to encourage adherence to exercise programs and which are readily implemented in most situations have included distribution of print materials and pedometers, as well as recommendation from the oncologist. Other strategies that may be less feasible have included provision of trainers, gym memberships, regular phone-calls, and psychologist-lead stress management sessions.

        The purpose of this study is to investigate the effects of group exer˗ cise program on depression in the elders with dementia. Subjects of this research were selected from the patients of Hyoja hospital(Yong˗ in, Korea). They were elders with dementia having minor to moderate degrees of cognitive function. Twenty-four subjects were randomly assigned into two groups, each with 12 people; exercise group and the control group. The control group only performed general physio˗ therapy, while the exercise group performed exercise program and general physiotherapy for 8 weeks. Depression of the exercise group and the control group were measured at baseline before the study, at 4 weeks, and at 8 weeks after the study. Depression was measured by Geriatric Depression Scale Short Form Korea Version(GDSSF-K). Firstly, when comparing the levels of depression within the same group, depression was significantly lower in the exercise group, after the group exercise program. However, depression of the control group did not show significant changes before or after the study. Secondly, when comparing the levels of depression of the control group and the exercise group, differences between the levels meas˗ ured before the study and 8 weeks after the study, was a statistically significant decrease of depression. Thirdly, effects of group exercise program according to the applied period were analyzed showing 8 weeks of group exercise to be more beneficial than 4 weeks. People who performed continuous group exercise program showed decrease in depression compared to the absence of group exercise program. This can infer beneficial effects of group exercise program. Group exercise program had desirable influence on decreasing the level of depression.

        Understanding awareness and wearing behavior of functional textiles for silver generation is expected to contribute to clothing products development to improve and maintain their health and marketing strategy fit for user characteristics. For empirical research, a survey was developed and the aged 50 and above were 332 respondents. The results of the study are as follows. First, the level of awareness for both comfort-oriented and health/safetyoriented functional fabrics in high health-conscious group was much higher than that in low health-conscious group. In number of wearing times, health body and high-conscious group wear comfort-oriented fabrics more frequently, while weak body group wear health/safety-oriented fabrics more often. The health-consciousness significantly influenced the possession of active sportswear with various functions. Second, the awareness of functional fabrics in exercise activities groups was much higher than that in exercise-conscious groups. High exercise activities group know more about the wet sensation-related fabrics and clothing materials for outdoor activities. Low exerciseconscious group put on health/comfort-oriented fabrics for casuals more frequent than functional fabrics for sportswear. High exercise activities group preferred to wear sportswear suitable for outdoor activities. The aged people have a lot of health/comfort-oriented functional casual wear appropriate for indoor activities regardless of exerciseconsciousness. However, the more they enjoy exercise activities the more they are interested in functional sportswear. Even though they were unconcerned with exercise, older people are interested in functional casual clothes. As a conclusion, the high interest in health and exuberant activities in silver generation arose the necessity of new multi-functional clothing products.

        The aim of this study was to investigate the effect of supporting surface instability to trunk and lower extremity muscle activities during bridging exercise combined with core-stabilization exercise. Thirty young healthy adults (15 males and 15 females) voluntarily participated in this study. Each subject was asked to perform bridging exercise combined with core-stabilization exercise on three different supporting surfaces (stable ground surface, the wooden balancing board, and the air cushion). The muscle activities were measured using surface electromyography (EMG) during performing exercise. To test statistical significance, one-way ANOVA with repeated measures was used with the significance level of .05. The findings of this study are summarized as follows. (1) There were significant differences in muscle activities on internal oblique, external oblique, gluteus medius, semitendinosus, biceps femoris, medial gastrocnemius and lateral gastrocnemius during exercise (p<.05). (2) The biceps femoris and lateral gastrocnemius showed significantly higher muscle activity on the wooden balancing board rather than on the ground, and semitendinosus, biceps femoris, medial gastrocnemius and lateral gastrocnemius showed significantly higher muscle activity on the air cushion rather than on the ground (p<.05). Therefore, it is concluded that muscle activities in the trunk and the lower limbs during bridging exercise combined with core-stabilization exercise was affected with instability of supporting surface. Further researches are needed to investigate the long term effect of bridging exercise on muscle activity with patient group.
