Purpose: This study aimed to evaluate the effects of lumbar stabilization exercise on the abdominal muscle-back muscle ratio in white-collar workers. Methods: Forty white-collar workers without any pain who worked at an information technology (IT) company located in the Gyeonggi province were included in this study. Of these, 20 subjects were randomly allocated to the lumbar stabilization exercise group, whereas the remaining 20 were randomly allocated to the control group. The lumbar stabilization exercise group performed a 40-minute-long exercise once a week for 8 weeks. The strength of the abdominal and back muscles was measured using the CENTAUR 3-D Spatial Rotation Device (BFMC, Germany). Data analysis was conducted using SPSS 18.0 for Windows. The Paired t-test was performed to compare the values measured before and after exercise within each group. The independent sample t-test was performed to analyze the differences between the 2 groups. The statistical significance for all the analyses was set at .05. Results: The strength of the abdominal muscles after the exercise significantly differed between the lumbar stabilization exercise group and the control group (p<0.05). However, the increase in the abdominal muscle-back muscle ratio was significant in only the lumbar stabilization exercise group (p<0.05), but not in the control group (p>0.05). Conclusion: The improvement of the abdominal muscle-back muscle ratio through lumbar stabilization exercise may have positive effects on lumbar stabilization. Moreover, lumbar stabilization exercise is considered beneficial for the prevention of back pain and musculoskeletal diseases.

Purpose: This study was conducted to investigate the effect of cigarette smoking on physical fitness (dominant hand grip power, dominant isokinetic leg muscle strength, abdominal muscle endurance, flexibility, cardiopulmonary endurance) and depression in patients with chronic low back pain. Methods: This study was a cross sectional study and subjects consisted of 60 young males with chronic low back pain. The subjects were allocated to two groups following a self-report survey: cigarette smoking group (n=25) or non-smoking group (n=35). Physical fitness (dominant hand grip power, dominant isokinetic leg muscle strength, abdominal muscle endurance, flexibility, cardiopulmonary endurance) were measured using objective methods and depression in patients with chronic low back pain was measured using the Korean version of center for epidemiologic studies depression (CES-D) scale. Results: The results of this study were as follows: In physical fitness, the cigarette smoking group showed a significant decrease in abdominal muscle endurance, flexibility, and cardiopulmonary endurance compared with the non-smoking group. Depression index (CES-D scale score) was significantly higher in the cigarette smoking group than in the non-smoking group. Conclusion: These results suggest that cigarette smoking had a negative effect on abdominal muscle endurance, flexibility, and cardiopulmonary endurance in patients with chronic low back pain. In addition, depression of patients with chronic low back pain was affected by cigarette smoking. Thus, we suggested that cigarette smoking may play a significant role in the deterioration of physical fitness and depression of chronic low back pain patients.

Objective: This study aimed to determine the effect of internal abdominis pressure(normal, hollowing and bracing) on trunk muscle activity during one leg bridge exercise. Design: Cross-sectional study. Methods: Thirteen healthy adults (9 men and 4 women) were instructed to perform Internal abdominal pressure(IAP) control(Normal, Hollowing, Bracing) during one leg bridge. Electromyography (EMG) data (% Maximum Voluntary Isometric Contraction, MVIC) were recorded three times on both sides of the participant's Internal Oblique(IO), Effector Spinae(ES), and Multifidus(MF) muscles and the average value was analyzed. Results: As a result, Abdominal bracing one leg bridge (BOLB) group and Abdominal hollowing one leg bridge (HOLB) group showed significantly increased muscle activation of bilateral internal oblique, erector spinae and multifidus activation compared to the Normal one leg bridge (NOLB) group (p<0.05). Abdominal hollowing one leg bridge (HOLB) group had a significant difference in bilateral Internal oblique muscle activation in compared to the NOLB group (p<0.05). Conclusions: Bilateral internal oblique, erector spinae, and multifidus muscles activation in healthy adults at one leg bridge exercise showed greater activation at abdominal bracing. Therefore, in this study, IAP control can be used as an indicator of choice to the dysfunction with trunk muscle weakness and corrective exercise subject's situation when the goal is to activate the trunk muscles by performing one leg bridge.

Purpose : The purpose of this study is to compare the effects on abdominal muscle thickness and breathing by applying trunk strength exercise and deep stabilization exercise along with breathing exercise, which is the main respiratory muscle during breathing, to present an efficient exercise method with diaphragm breathing. Methods : This study was performed on normal 6 females and 14 males subjects. They were divided into 2 groups which trunk strength exercise and deep stabilization exercise group. The trunk strength exercise group (TSE) attended prone press-up, crunch and pelvic tiling. The deep stabilization exercise group (DSE) attended abdominal drawing, horizontal side-support and bridging exercise. Breathing exercise was performed for each set break time for 1 minute. Results : First, in the comparison of the change in the thickness of the abdominal muscle between the trunk strength training group and the deep stabilization group before and after exercise, there was a statistically significant difference in the comparison of transverse abdominis (TrA), rectus femoris (RF), external oblique (EO), internal oblique (IO) (p<.05). However, there was no significant difference in any comparison between groups (p>.05). Second, in the comparison of changes in respiratory function between the trunk strength exercise group and the deep stabilization exercise group before and after exercise, there were statistically significant differences in the exerted forced vital capacity (FVC), forced expiratory volume at one second (FEV₁), peak expiratory flow (PEF) in the comparison before and after the experiment (p<.05). However, there was no significant difference in any comparison between groups (p>.05). Conclusion : As a result of this study, it can be said that both trunk strength exercises and deep stabilization exercises along with diaphragm breathing are exercises that strengthen deep and superficial muscles, and have a positive effect on breathing function as well as muscle strength. However, it is not known which exercise was more effective, and because it was combined with breathing exercise, the interference effect appeared.

Purpose: This randomized study was done to compare the effects of a 6 month Tai Chi exercise and a self-help program on balance, flexibility and muscle strength in women with osteoarthritis (OA). Method: In this experimental study, 82 women with OA recruited from outpatient clinics or community health centers were randomly assigned either to a Tai Chi group or a self-help group. Thirty women (mean age = 62 years) in the Tai Chi group and 39 (mean age = 59 years) in the self-help group completed posttest measures (balance, flexibility, oxygen consumption, abdominal muscle strength, back muscle strength, and grip strength) at 6 months. Results: After the 6 month, Tai Chi participants had significantly greater balance (mean difference = 2.9 vs. 0.9 for the self-help), grip strength (mean difference = 4.6 vs. 0.9 for the self-help), and back muscle strength (mean difference = 4.1 vs. -0.3 for the self-help). However, flexibility, oxygen consumption, and abdominal muscle strength were not significantly different between the groups. Conclusion: Tai Chi increased balance, grip strength and back muscle strength in older women with osteoarthritis compared to the self-help program. Whether these changes improve physical functioning and fall prevention requires further study.
