Objectives : This study was performed in order to investigate the relation of body composition analysis and radiological parameter(lumbosacral angle, lumbar lordortic angle, lumbar gravity line). Methods : This study was carried out with the data from comprehensive medical testing. 75 subject aged 20-59 performed the segmental bioelectrical impedance analysis, questionnaire. And lumbosacral angle, lumbar lordortic angle and lumbar gravity line were measured in the standing position x-ray. Then we analyzed the data. Results : Low back pain(LBP) prevalence in high obesity index(Body Mass Index(BMI), Percentage of Body Fat(PBF), Waist Hip Ratio(WHR)) group was higher than LBP prevalence in normal obesity index group(p<0.01). In LBP group, lumbosacral angle, lumbar lordortic angle were significantly lager than Non-LBP group(p<0.001). And 75% of LBP group indicated abnormal lumbar gravity line ratio(0.67 < Normal lumbar gravity line ratio <1.00). When it comes to analyze relation between obesity index and radiological parameter, no-significant change was seen. Conclusions : This study carried as following research after the study on relation of obesity, LBP and trunk muscle strength. Results from this investigation showed positive correlation between obesity and LBP prevalence. But obesity index didn't indicate significant correlation with structural changes of lumbar vertebrae. When considering prior research, trunk muscle strength changes were more related to LBP prevelence in obese people. This results are expected to explain causes of LBP in obese group.

This study examined the effect of the respiratory training centered at forced breathing exercise of blowing out a candle on the improvement of adults' respiratory ability, which means the increased muscle strength of body trunk. After the four-week candle-blowing breathing training, the forced vital capacity (FVC) increased statistically significantly (p<.05). The forced expiratory volume in one second (FEV1) did not show a statistically significant difference before and after the four-week intervention(p>.05). The peak expiratory flow rate (PEF) statistically significantly increased after the four-week blowing-out-the-candle training (p<.05). This study examined the relationship between forced breathing training and pulmonary function of healthy adults including FVC, FEV1, and PEF, which means the increased muscle strength of body trunk, by implementing blowing-out-the-candle breathing exercise centered at forced respiratory exercise and obtained significant results. Further studies that use a sample of patients with advanced respiratory system disease for whom physical therapy is absolutely necessary will be required in the future.

The purpose of the dissertation is to offer basic data available for being conducive to application of a training program by comparatively analyzing the players' physical strength, the knee joint, a hip joint, power of the trunk joint and muscle power in order to study isokinetic strength and muscle power between short distance athletes and Taekwondo players. This study measured peak power, %Body weight peak power, always power, and %Body weight peak power targeting 8 male athletes and 8 male Taekwondo players who warmed up 10 minutes before from the test to reduce repulsion and unfamiliarity at the instrument. The power of the knee joint($60^{\circ}$/sec), muscle power($180^{\circ}$/sec), were measured by using HUNOM(U.S.A). As a result of the physical strength, statistically, short distance athletes were indicated to be better in muscle strength, muscular endurance than Taekwondo players, and there was no significant difference between flexibility, power, and muscular endurance. Although the short distance athletes were indicated to be better in right and left muscle strength of knee joint than Taekwondo player, there was no significant difference and Taekwonde players were indicated to be higher at the right and left muscle power than short distance athletes.

The purpose of this study was to examine the effect of Yoga and Pilates training on the obesity indexes, muscle mass in each body part and physical fitness of male college students in an effort to provide some clinical information on exercise prescription. The subjects in this study were 20 selected obese male students. A yoga group and a pilates group were organized with 10 students each, and the training was provided for 12 weeks, 5 times a week, 90 minutes each. The findings of the study were as follows: First, both of yoga and pilates made significant differences to obesity indexes(an increase in skeletal muscle mass, a decrease in BMI, a decrease in body fat rate and a decrease in WHR), to muscle mass in each body part(an increase in muscle mass on the right arm, left arm, trunk, right leg, and left leg), and to physical fitness(an increase in lower extremity muscle strength, muscular endurance, flexibility, left balance and right balance). Second, pilates exercised a more signifiant influence than yoga on an increase in skeletal muscle mass, the improvement of muscle mass in each body part(an increase in muscle mass on the right arm, left arm, trunk, right leg and left leg), and the improvement of balance(left and right). Third, yoga had a more significant impact on a decrease in BMI, body fat rate and WHR. Given the findings of the study, yoga and pilates seem to be efficient exercise programs to improve the obesity indexes of obese male college students and promote their health.

Activity of the trunk muscles is essential for maintaining stability of the lumbar spine because of the unstable structure of that portion of the spine. The central nervous system deals with stabilization of the spine by contraction of the abdominal and multifidus muscles in anticipations of reactive forces produced by limb movement. Recent evidence indicates that the lumbar multifidus muscle and transversus abdominis muscle may be involved in controlling spinal stability. Stabilization training in neutral spine is an integrated approach of education in proper posture and body mechanics along with exercise to improve strength, flexibility, muscular and cardiovascular endurance, and coordination of movement.

This study is to identify the effects of pilates exercise on the body composition, blood biochemical factor, isokinetic knee and trunk muscle function in menopause middle-aged women. In order to carry out this study, Twenty menopause middle-aged women were divided into two groups: pilates exercise group (PEG; n=10) and control group (CG; n=10). PEG group performed pilates exercise for 50 min per day, 2days/week for 12 weeks. As a result, first, there was an interaction effect on body fat mass in body composition. Second, there was no significant result in blood lipid and serotonin, but there was a positive trend. Third, in the isokinetic knee and trunk muscle function, the interaction effect was found in the flexor peak torque of trunk strength. The effect of the 12-week Pilates exercise on body composition, bone density, blood biochemical factor, and isokinetic muscular strength of menopause middle-aged women is partially insignificant, but the overall effect tends to be positive. In conclusion, the Pilates exercise conducted in this study is appropriate for menopause middle-aged women.

This study was designed to investigate the effect of a combined stimulus which was composed of chiropractic massage and thermotherapy on the relief of mental and physical stress. Fifteen healthy male subjects were treated with three type of stimuli; control (without any stimulus), a single stimulus (only chiropractic) and a combined stimulus. To evaluate the effects of stimuli, visual analogue scale (VAS), trunk extension, electromyogram (EMG) on erector spinae muscle and electrocardiogram (ECG) were measured and analyzed before and after stimuli. In the control group, there were no significant changes in EMG root mean square (RMS) value and low Frequency/high Frequency (LF/HF) ratio (p > 0.05, p > 0.05). However, both stimulus groups showed significant increases in trunk extension and EMG RMS values (p < 0.05, p < 0.05), but significant decreases in LF/HF ratios (p < 0.05). Particularly the decrement rate in LF/HF ratio was significantly higher in the combined stimulus group than that in the single stimulus group (p < 0.05). Also, a significantly lower VAS was recorded after combined stimulus. Our findings indicate that the combined stimulus might not only improve flexibility and strength of muscle, but also active parasympathetic nerve activity. The combined stimulus may thus contribute to relieve the stress and to enhance the muscle function.

The purpose of this study was to find the effects of the lumbar stabilizing exercise on the isometric lumbar extension strength and the range of motion of lumbar extension. 16 healthy subjects were recruited (9 males, 7 females, mean age 25${\pm}$3.2). They performed 5 types of exercises 5 times per week for 4 weeks. We evaluated isometric trunk extension strength (0, 12, 24, 36, 48, 60, $72^{\circ}$) by MedX(Ocala, FL) and measured range of motion of lumbar extension. All measurements were measured at pre-exercise and 4 weeks post-exercise. The results of this study were summarized as follows; After 4 weeks of exercise, isometric lumbar extension strength was generally increased but there were only significant differences at $12^{\circ},\;24^{\circ},\;48^{\circ}$. The range of motion of lumbar extension was increased (p<.05). The isometric lumbar extension strength correlated with the range of motion of lumbar extension. In conclusion, our results have shown that lumbar stabilizing exercise influenced both lumbar extension strength and range of motion of lumbar extension.

The purpose of this study was to examine the effects of graded low back exercise program with patient education about low back pain care on abdominal strength, endurance and flexibility of waist of chronic low back pain patents. For this study 13 patients aged 40 to 60 were selected as subjects, who suffered from low back pain and got diagnosed by physician. The exercise program and the education were executed for total 6 weeks, posture education were executed with physical exercises over first 1 to 4 weeks period and over 5 to 6 weeks the exercises were executed. The effect of the exercises and the education were evaluated through weights, WHR, fat(%), flexibility by sit-and-reach and trunk extension test, strength by sit-up test and back sit-up test. Weights were, decreased after physical exercise and education, but there was no statistical significance. Wasit hip ratio(WHR) and fat(%) were decreased after physical exercise and education, but there were no statistical significances. Sit-and-reach was significantly increased from $13.68{\pm}5.59cm$ to $19.45{\pm}3.81cm$ after education and physical exercise(P<0.05). Trunk extension was significantly increased from $30.31{\pm}11.34cm$ to $40.88{\pm}6.16cm$ after education and physical exercise(P<0.05). Sit-up and Back sit-up were increased after physical exercise and education, but there were no statistical significances. These results suggest that graded low back exercise program with patient education about low back pain care increase the abdominal strength, endurance and the flexibility of waist in low back pain patients.

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.
