This study was to verify effect on muscle strength of trunk and body composition for elderly according to spinal stability exercise with three dimension. We recruited forty elderly participants(twenties as training group, the other twenties as control group) over sixty five aged. The participant performed muscle strength estimation to exercise of eight direction using spinal stability training system. Also, we estimated body composition in participants using inbody 720. Trining group performed direction exercise(F, FOR, R, BOR, B, BOL, L, FOL) and multiple exercise with band exercise, strengthening gym and walking during thirty minute. But control group only performed multiple exercise without direction exercise. All training progressed three days a week for eight weeks. The results showed that muscle strength of trunk in training group increased significantly from 79.9 point to 85.6 point with reducement of body weight, body fat and BMI. However, control group showed a few exercise effect with increasement of amount of muscles and reducement of body fat without muscle strength of trunk. These results means that spinal stability exercise could be helped to prevent obey and fall of elderly caused by muscle strengthening and improving body composition. This could be applied to develop rehabilitation program efficiently based these data.

This study aims to investigate the effect of trunk muscle strengthening exercises on balance performance of sitting posture and muscle tone, targeting the children with spastic diplegic cerebral palsy. 16 children with spastic diplegic cerebral palsy in IV phase of GMFCS were sampled at random and the tests were conducted for 6 weeks, 3 times per week. For experimental groups, only trunk muscle strengthening exercises were conducted and for control groups, only basic physical therapy was conducted. The trunk muscle strengthening exercise consisted of 2 exercises to strengthen abdominal muscles and back muscles. BPM(Balance Performance Monitor) was used to measure balance performance and MMAS(Modified Modified Ashworth Scale) was used to measure muscle tone. As a result, the changes of sitting balance performance in experimental groups and control groups show significant difference in the changes of sway path and sway velocity(p<.05), the comparison of changes in sitting balance performance in between experimental groups and control groups show significant difference in the changes of sway path and sway velocity(p<.05). Knee flexor muscles and hip adductor muscles in both groups show no significant difference in changes of the muscle tone(p>.05). Therefore, the balance performance in both experimental groups and control groups was improved. However, the experimental group had more significant improvement in balance performance and no change in muscle tone was detected in both groups. Thus, these findings show trunk muscle strengthening exercises are effective in improving the balance performance of sitting posture for the children with spastic diplegic cerebral palsy without changing muscle tone.

The purpose of this study was to know influenced on the change of Oswestry back pain disability index(OBPDI), isometric muscle power(IMP), muscular activation with chronic low back pain(CLBP) patients after Trunk Stabilization Exercise. Intervention was provided 6 weeks(5 days a week). Muscular activation was measured during IMP(Muscles : transversus abdominis : TA, internal obliqus : IO, external obliqus : EO, rectus abdominis : RA and erector spinae: ES). The results were as follows. 1. OBPDI about the MBE and the SE groups had effective decrease pain and disability. 2. IMP of intervention after the MBE and the SE groups had effective improve muscle power. 3. Muscle activation during IMP of intervention after was : TA, IO, RA had increase in the MBE and the SE groups. EO muscle activation during IMP of intervention after had increase only MBE groups. This shows that the MBE and the SE groups had effective increase because it has effective improve muscle power. Therefore, this study shows ￡hat trunk stabilization exercise program influenced on the change of OBPDI, IMP, muscular activation with CLBP patients.

The purpose of this study is to confirm the effects of a 6-week high-intensity combined training program on canoe athletes' cardiorespiratory function, isokinetic trunk strength, and anaerobic power. For the purpose of this study, the high-intensity combined training program was applied to 9 high-school canoe athletes. The high-intensity combined training program consists of aerobic exercise performed 2 times a week (Tuesday and Thursday), anaerobic exercise performed 3 times a week (Monday, Wednesday, and Friday), and flexibility exercise performed 5 times a week. The core of the high-intensity combined training program was the anaerobic training program performed with 100% weight for repetition; otherwise, the existing training method was divided into the percentage (%) of the 1RM. The aerobic exercise and the gym ball exercise are performed subsidiarily. Results showed that there was a statistically significant difference in height and muscle mass, whereas there was no statistically significant difference in weight, body fat percentage, and BMI followed by the high-intensity combined training program. There were statistically significant differences in maximum oxygen uptake and total exercise time. The angular velocity of 30°/sec showed a statistically significant difference in the peak torque item of flexors only. Also, the angular velocity of 120°/sec showed a statistically significant difference in the total work item of extensors only; however, there was no statistically significant difference in all the items of peak power, average power, and peak drop. In conclusion, it seems that the high-intensity combined training program may be applied as a training program for enhancing canoe athletes' performance. For further studies, more than 6 weeks training program with more participants would show improved results of isokinetic strength and anaerobic power in athlets.

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.
