This study examines the effects of different types of bridge exercises on the thickness of trunk muscles through ultrasound fusion imaging on 32 students. The thickness of the internal oblique (IO), external oblique (EO), transverse abdominis (TrA), and multifidus (Mf) muscles were measured in three different bridge exercises. The exercises included a supine bridge exercise, which was performed on a fixed support surface (Exercise A), a gym ball bridge exercise (Exercise B), and a sling bridge exercise (Exercise C). There were significant differences among the three bridge exercises in the IO, TrA, and Mf muscles. The IO was thickest in Exercise B followed by Exercise A and C. In contrast, the TrA and the Mf muscles were thickest in Exercise C followed by Exercise A and B. Therefore, the sling bridge exercise may be a more effective method of enhancing trunk muscle thickness than the exercises performed in other positions. Until recently, no previous studies had observed substantial changes in muscle thickness using ultrasound fusion imaging. This study suggests that sling bridge exercises contribute most to the activation of trunk muscles. Therefore, the research can contribute to the prescription and application of bridge exercises in clinical practices.

Purpose : Stabilization exercise and respiratory muscle training are used to train trunk muscles that affect postural control and respiratory function. However, there have been no studies that combine stabilization exercise and respiratory muscle training. The purpose of this study is to investigate effects of stabilization exercise with and without respiratory muscle training on respiratory function and postural sway. Methods : Fifteen healthy adults were recruited for this experiment. All the subjects performed stabilization exercise with and without respiratory muscle training. For stabilization exercise with respiratory muscle training, the subjects sat on a gym ball wearing a stretch sensor. The subjects inspire maximally as long as possible during lifting one foot off the ground, alternately for 30 seconds. The stretch sensor was placed on both anterior superior iliac spine (ASIS), and the stretch sensor was used to monitor inspiration. For stabilization exercise without respiratory muscle training, the subjects sat on a gym ball and lifted one foot off the ground, without respiratory muscle training. Kinovea program used to investigate postural sway tracking during exercise. The maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP) were measured using a spirometer to investigate changes of respiratory muscle strength before and after exercise. A paired t-test was used to determine significant differences postural sway tracking, MIP, and MEP between stabilization exercise with and without respiratory muscle training. Results : There were significantly lower a distance of postural sway tracking during stabilization exercise with respiratory muscle training, compared with stabilization exercise without respiratory muscle training (p<.05). The MIP and MEP were significantly increased after stabilization exercise with respiratory muscle training compared with before stabilization exercise with respiratory muscle trianing (p<.05). Conclusion : The results of this study suggest that stabilization exercise with repiratory muscle training would be recommended to improve postural control and respiratory muscle strength.

Purpose : The purpose of this study was to improve the quality of life of people aged 65 and over by reducing musculoskeletal pain and increasing balance and muscular strength in their lower-extremities through aerobic exercises and the use of Thera-Bands and gym balls. Method : Fifteen out of 30 women who used a welfare center for the elderly in C City performed exercises using Thera-Bands and gym balls, and the remaining 15 elderly women did aerobic exercises. Both groups performed their respective exercises three times a week over a four-week period, for 50 minutes each time. Pain (VAS), balance (TUG), and lower extremity muscular strength were measured as evaluation tools. The data were analyzed using the statistical software SPSS 18.0 for Windows. The Wilcoxon signed-rank test was performed to compare the differences within each group, and the Mann-Whitney U test was used to compare the two groups in terms of their differences both before and after the participants' respective exercise programs. Results : No differences were found between the two groups, although there were some differences within each group in terms of levels of pain, muscular strength, and balance. Conclusion : The aerobic and muscle strength exercise programs had positive effects on all variables, including pain, balance, and muscular strength in the lower extremities. Therefore, the combination of aerobic and muscle strength exercises may be effective in improving the quality of life of elderly people.

The purpose of this study was to verify the validation of effect on improvement of muscle strength unbalance according to exercise load deviation during rowing exercise. We performed evaluation of muscular activity and joint torque before the test. We recruited twenty subjects who one side's muscle strength is bigger in more 20% than other side. Subjects divided two groups. One is dominant left side and the other was dominant right side. Subjects performed rowing exercise in electric load deviation rowing equipment (Robo.gym, Humonic Co., Ltd., Daegu, Korea). Exercise performed four sets a day including 25 times a set, and three days a week. Measurements consist of evaluation of muscular activity and joint torque. Exercise load deviation adapted that different value of muscle strength in both arms multiplied 1RM% and added 1RM 50%. The results in adapted load deviation showed that the differences of maximal peak torque in 22.75% were getting increase significantly during exercise in 5.72%. This interpreted that rowing exercise with loading deviation types could provide muscle strength and muscular endurance exercise in same time for balance. Our study found out that loading deviation could provide muscle strength and muscular endurance exercise for improving muscle unbalance.

Elbow joint injuries during exercise mostly occur by repeated stress to the joint than direct trauma. A pitcher who uses his arm above his head is most likely to be injured. So learning the right way to exercise and gaining the strength by maturating the body are essential for diminishing the chance of injury. On lateral ulnar tendon injury, which is most commonly injured area on elbow joint, pitchers generally complain of pain in arm movement above head and reduction of velocity, accuracy, and number of pitching. When there is pain on upper arm in harsh using, the stress fracture must be thought and epicondylar physis fracture of medial arm can occur by repeated abduction stress and contraction of flexors on forearm on children with immature skeleton. Osteochondritis dissecans of capitullum occur in young athletes who use there upper limb continuously lifting weights and gym work. And stress of abduction-extension includes damage of soft tissue and bone components, post medial crush syndrome, lateral ulnar ligament injury, extensor-abductor injury, stress of radius- capitullum are in this category.

PURPOSE: The purpose of this study was to investigate the effects of a group exercise program with competitive games on balance in chronic stroke patients. METHODS: The subjects were chronic stroke patients living at home after their discharge from the hospital. A total of 32 subjects were divided into two groups. The experimental group performed a group exercise program with competitive games, and the control group performed individual exercises. The exercise program duration was one hour, and it comprised 10 minutes of stretching, 40 minutes of the main exercise, and 10 minutes of stretching at the end. The experimental group was divided into two teams of 8 players each and played competitive games (transfer a gym ball to another person, relay 10 m walking and return, transfer an object to the next person using both arms while sitting). The control group performed an arm/trunk exercise for 15 minutes and gait training for 25 minutes. These exercises were conducted twice a week (4 weeks). The Berg Balance Scale (BBS) and timed up-and-go (TUG) tests were performed to confirm the change in balance. RESULTS: In the experimental group, BBS showed a significant increase (p < .05) and TUG showed a significant decrease (p < .05). In the control group, there was no statistically significant change in the BBS. However, the TUG showed a significant decrease (p < .05). The BBS and TUG both showed statistically significant differences (p < .05) in the between-group comparison of the change in pre-post intervention values. CONCLUSION: A group exercise program with competitive games to improve the balance ability for fall prevention in chronic stroke patients could be used as a good intervention method.

Purpose: The purpose of this study is to investigate the effects of exercising on a stable and unstable surface for a period of six weeks on the arms of female university students in their twenties. Methods: The subjects consisted of 20 female university students. The experimental group consisted of ten individuals who exercised on an unstable surface, and the control group consisted of ten individuals who exercised on a stable surface. The exercise program was composed of aerobic exercises (i.e. Back and forth movements for clapping and raising cross with both arms) and muscle-strengthening exercises (i.e. Push-ups and raising arms). We measured the subjects before the experiment and after the exercise program using the following measurements tool: a ruler and T-scan plus. The same person measured changes in arm size with a ruler three times and calculated the average to minimize any errors in measurement. We controlled the subjects to measure the amount of arm muscle with a T-scan plus. Twelve hours before the measurements were taken subjects were not permitted to exercise, and four hours before the measurements were taken subjects were not permitted to eat anything. Results: The two groups had no significant difference, but each group felt the effect of the exercise program. Conclusion: There was no difference between the experimental group and the control group. However, it was determined that the exercise had a greater effect on an unstable surface than a stable surface.

PURPOSE: The purpose of this study was to identify the effect of abdominal stabilization exercise with Stabilizer and Gymball. METHODS: The participants were divided randomly into 2 groups each of 20 participants in the gymball exercise group and 20 participants in the exercise group. The changes of respiratory muscle activity between the two groups were measured three times a week for 4 weeks. The activity of rectus abdominis and internal oblique was measured using surface EMG to measure respiratory muscle activity. The training was repeated five sets, and one set was repeated 6 times with one 10 second exercise and 5 second rest. RESULTS: The results of the study showed that there was a significant difference in the amount of respiratory accessory muscle activation, inspiratory pressure, respiratory minute volume at the experimental group with stabilizer and control group with gymball exercise. Between-group difference was statistically significant only for rectus abdominis muscle activation. CONCLUSION: Both the stabilizer and the gymball exercises were effective in improving the respiratory rate but there was no difference between the two groups. Also, when comparing activity of muscle in both group, both groups were effective in improving and more effective than improvement of muscular activity of stabilizer in muscle of stabilizer.
