Purpose : This study attempts to examine the effect of the balance exercise on the unstable surfaces for the vital capacity in healthy adults. Methods : A total of 13 subjects was randomly divided into a breathing exercise training group (n=7) and a breathing and balance exercise training group (n=6). Changes in vital capacity and respiratory muscle activity were measured before and after the intervention. The intervention was performed three times a week for four weeks. Forced vital capacity (FVC), forced expiratory volume at one second (FEV1) and maximal voluntary ventilation (MVV) were used as measurement tools for the vital capacity test. Electromyography (EMG) was also used to examine respiratory muscle activity. Result : The breathing exercise training group showed significant improvement in terms of FVC, FEV1 and external oblique (EO), and transverse abdominis/internal oblique (TrA/IO) of MVV. The breathing and balance exercise training group showed significant improvement in terms of FVC, MVV and EO, TrA/IO of FVC and rectus abdominis (RA), EO, and TrA/IO of MVV. However, in comparing changes in vital capacity and respiratory muscle activity before and after the training, the breathing exercise training group and the breathing and balance exercise training group showed a significant difference in terms of MVV. Conclusion : This study is as a preliminary study to find out the relation between a balance exercise and a vital capacity, it is considered to require a further study with several revisions of subjects, duration and time for an intervention.

PURPOSE: The aim of this study was to review the effects of exercise intervention on blood glucose control in obese type 2 diabetic patients. METHODS: The PubMed and KERISS search engines were used and 61 papers that met the key questions were selected. RESULTS: Exercise is an effective intervention for the control of blood glucose in type 2 diabetic patients because it does not impair glucose transport in the skeletal muscle induced by muscle contractions. Insulin resistance, which is characteristic of type 2 diabetes, is caused by decreased insulin sensitivity or insulin responsiveness. Acute exercise improves the glucose metabolism by increasing the insulin-independent signaling pathways and insulin sensitivity in the skeletal muscle, and regular long-term exercise improves the skeletal muscle insulin responsiveness and systemic glucose metabolism by increasing the mitochondrial and GLUT4 protein expression in the skeletal muscle. CONCLUSION: The improvement of the glucose metabolism through exercise shows a dose-response pattern, and if exercise consumes the same number of calories, high intensity exercise will be more effective for the glucose metabolism. On the other hand, it is practically difficult for a patient with obese type 2 diabetes to control their blood glucose with high intensity or long-term exercise. Therefore, it will be necessary to study safe adjuvants (cinnamic acid, lithium) that can produce similar effects to high-intensity and high-volume exercises in low-intensity and low-volume exercises.

Purpose: The aim of this study was to identify the effects of the lower trunk stabilization exercise using neurodevelopmental technique (NDT) on muscle activity in lumbar region and balance in the patients with hemiplegia. Methods: Fifteen participants were allocated in two groups: NDT group (n=8) or control group (n=7). NDT group performed NDT exercise program, while control group conducted walking exercise. Both interventions were given for 30 minutes a day, 3 times a week, for 5 weeks. To measure the muscle activity in rectus abdominis (RA), external oblique (EO) and internal oblique (IO), electromyography (EMG) was used. And, Timed-Up and Go (TUG) test and Berg-Balance Scale (BBS) were performed to assess balance before and after intervention. Results: NDT group showed a significant improvement of muscle activity in RA and EO, while control group did not show significant changes in three muscles. Also, there was a significant difference in muscle activity of RA and EO between two groups. In BBS and TUG test, participants in two groups showed significant improvements after intervention. Especially, significant difference was observed in TUG test between two groups (p<.05). Conclusion: This study demonstrated that NDT exercise is an effective intervention to improve the muscle activity in trunk region and to increase balance in patients with stroke. Thus, we suggested that NDT exercise program would be a treatment intervention in stroke rehabilitation.

Purpose: The purpose of this study was to examine the effects of exercise intervention, including dumbbell(weight lifting), walking, and yoga, on the body composition, physiologic factors, body image, and perceived health in the community-dwelling women. Method: This study utilized pretest-posttest design with three types of exercise interventions. The types of exercise intervention included dumbbell, walking, and yoga. Results: A total of 136 subjects were included: 49 for dumbbell, 67 for walking, and 20 for yoga. As measures of body composition, BMI, body weight, and body fat rate were significantly improved only after dumbbell intervention(p<.01). Systolic blood pressures were significantly decreased in the groups of dumbbell and walking. Diastolic blood pressure was significantly declined only in the walking group. Vital capacities and body image were improved in all groups(p<.01). However, total cholesterol levels were not improved in all groups(p>.05) and none of the measures for perceived health state were not significantly changed in all groups(p>.05). Conclusion: From the findings of this study, it was demonstrated that the effects of exercise interventions were differentiated by their types and variables to be affected. Therefore, future studies that apply the tailored exercise intervention to each age-categorical group are needed.

PURPOSE: The aim of this study was to identify the effects of joint mobilization intervention combined with exercise on range of motion (ROM), pain intensity, and functional performance in adolescent baseball players with internal impingement syndrome of the shoulder. METHODS: The subjects were 30 adolescent baseball players diagnosed with internal impingement. Ten subjects were randomly assigned to each of 3 groups: Group 1 (exercise only), Group 2 (joint mobilization combined with exercise), and Group 3 (rest-only control group). Three weekly interventions were given for 4 weeks (the control group rested for 4 weeks). The main outcome measures were goniometer, visual analogue scale (VAS), and Korean Kerlan Jobe shoulder-elbow (K-KJOC) scores. The ROM (external and internal rotation), pain intensity (at the moment of throwing), and functional performance were compared among the groups. RESULTS: No significant difference was observed among the groups in the range of external rotation of the shoulder before and after the intervention, but the range of internal rotation was significantly increased in Group 2 compared to Groups 1 and 3. Pain intensity was significantly lower in Group 2 than in Group 1 and 3, and functional performance was significantly increased in Group 2 compared to Group 1 and 3. CONCLUSION: An intervention that combined joint mobilization with exercise was more effective than resting or exercise alone for rapid recovery from sports injury and improvement in athletic performance.

PURPOSE: The purpose of this study was to provide clinical basic data to reduce pain and improve function by comparing neck muscle activity and neck alignment using self-stretching and passive stretching exercises for chronic neck pain caused by forward head posture. METHODS: The subjects were divided into 15 subjects assigned to perform self-stretching exercise and 15 subjects assigned to perform passive stretching exercise. The intervention was conducted for a total of 4 weeks. The muscle activity in the neck was measured by surface electromyography (EMG) before intervention, and craniovertebral and cranial rotation angles were measured by X-ray. The 4-week intervention was conducted and the above items re-measured in the same manner and analyzed. RESULTS: Muscle activity within both groups after intervention using self-stretching or passive stretching exercise was significantly different (p < .05)(p < .01). Neck alignment of both groups was significantly different (p < .001)(p < .01). Further, muscle activities of the upper trapezius and splenius capitis muscles showed significant differences (p<.05). Lastly, neck alignment showed statistically significant difference (p < .05). CONCLUSION: Self-stretching exercise activated motor nerves as a posture correction exercise, thereby improving inhibition of muscle activity, muscle contraction delay, and pathological conditions of the muscle. For future research, interventions of self-stretching exercise will be needed for patients with chronic back pain accompanied by forward head posture, and various clinical studies on postural improvement of forward head posture by maintaining a normal muscle tone state are needed.

Falls are a major sources of death and injury in elderly people. Aged-related changes in the physiological systems which contribute to the maintenance of balance are well documented in older adults. These changes coupled with age-related changes in muscle and bone are likely to contribute to an increased risk of falls in this population. Regular exercise may be one way of preventing falls and fall-related fractures. However, the optimal exercise prescription to prevent falls has not yet been defined. On the literature review of exercise intervention for fall prevention in the elderly, exercise appeared to be a useful tool in fall prevention by improving fall risk factors. The optimum exercise prescription; moderate intensity frequency of 3-4 times per week, duration of 30-60minutes can contribute to decreased hazards and number of fall. Fall prevention protocol should include safety, falling effect, enjoyment, and easiness to follow for older people. Effective exercise programs suggested for fall prevention were such as weight-bearing exercise, resistance exercise, lower muscle strength with elastic band, swiss ball exercise walking, tai chi, and yoga.

The aim of this study was to examine the effects of repeated passive movement (RPM) of different velocities on the improvement of knee joint position sense (JPS) in post-stroke patients with hemiplegia, thereby investigate the possibility of clinical application in the initial stage of rehabilitation for patients with post-stroke hemiplegia. Thirteen hemiplegic patients participated in this study. For the subjects' knee JPS tests, a passive angle reproduction test and an active angle reproduction test were performed prior to and after the intervention, which involved 30 repetitions of passive full-range-of-motion flexion and extension exercise of the knee joints at randomized degrees of $0^{\circ}/s$, $45^{\circ}/s$, and $90^{\circ}/s$. Paired t-test analysis was done in order to compare changes in the pre- and post-intervention knee JPS. One-way repeated analysis of variance was used in order to compare changes in JPS after intervention at three different movement velocities. The level of significance was set at .05. The result was that the subjects' post-intervention knee JPS significantly improved after the RPM exercise at a $45^{\circ}/s$ and a $90^{\circ}/s$ relative to the RPM exercise $0^{\circ}/s$ (p<.05). JPS changes with RPM intervention at the rapid velocity of $90^{\circ}/s$ were most increased, suggesting the most effective enhancement in knee JPS is with intervention at the velocity (p<.05). Therefore, RPM intervention at a half or higher velocity improved stroke patients' knee JPS. During the initial stage of rehabilitation for patients with post-stroke hemiplegia, the efficient application of the RPM exercise at a half or higher velocity will be possible.
