This study aims to organize the prototype design method of compression wear for women professional soccer players. Despite the excellent performance of female soccer players in world competition, most functional wear has been developed mainly for men, so professional female athletes have fewer choices. Soccer is a sport requiring core and lower body muscle strength, and muscular endurance for long periods of playing or walking on the field. Female soccer players did not differ much in upper body compared to other women, but their lower body had a smaller hip circumference than waist circumference and a larger thigh circumference, requiring compilation considering the physical characteristics and movement of athletes. Female soccer players wear sports bras while playing but regular bras and compression wear during normal exercise because they sweat on under their breast, which irritates sensitive skin. For core muscles in the upper body and to support for thigh and hip muscles in the lower body, the uniform in this study was designed by reducing the body size of a professional female soccer player in her 20s and the actual measurements of commercial compilation software to 81% of the chest circumference, 95% of the waist circumference, and 78% of the hip circumference. The design experiment in this study was a simple exercise and did not produce produce results for long-term exercise and performance improvement, but can be used to design a composition pattern system for other professional female athletes.

Background: The purpose of this study was compare and analyze the flexibility and dynamic balance in adolescents with idiopathic scoliosis and provide scientific basis for effectively treating idiopathic scoliosis. Methods: The subjects of this study were 20 members of adolescences. To measure the flexibility of the spine, a left buckling instrument was used, and it was measured using a modified sit and reach test. They were randomly divided into core exercise with sling program group (n=10) and general exercise program group (n=10), each consisting 50 minutes each for 4 times per week for 8 weeks. Results: The results of the study are as follows. First, Both groups were increased statistically significantly in spinal flexibility but no significant differences have been found between the two groups after 8 weeks of exercise. Second, Both groups were increased statistically significantly in balance ability of dynamic foot pleasure ratio but no significant differences have been found between the two groups after 8 weeks of exercise. Conclusion: In summarizing the results of this study, sling exercise with core exercise was effective in the decrease of flexibility and stability than general scoliosis exercise in adolescents with idiopathic scoliosis. It is also believed to be applicable to spinal diseases caused by muscular weakness since it is effective in strengthening core muscle strength.

Objectives Osteoarthritis is hard to manage with both conventional and Korean medicine treatment. The core outcome set (COS) to demonstrate the effectiveness of Korean medicine treatment has not been established yet. We aimed to present preliminary data of COS by performing a literature review on the evaluation indices used in existing clinical research. Methods We examined the literature from 2000 to 2017 in two Korean electronic databases (Korea citation index and oriental medicine advanced searching integrated system) by searching for the following 3 terms 'total knee replacement (Korean)', 'total knee replacement,' and 'knee surgery.' We found 333 articles; among them, 50 duplicates were removed. Finally, we selected 160 articles after complete screening. We then extracted measured indices and clinical outcomes from the selected articles and categorized the relevant criteria. Results According to this study, the hospital for special surgery and knee society, range of movement angle, cross leg, Berg balance scale and balance ability, muscle strength, 6 minutes walking test, visual analogue scale, self-efficacy, the 12-item and 36-item short form survey and self-rated health status are the most commonly used outcomes of knee. Conclusions This study found that the several categories after total knee replacement (TKR) are being evaluated in the literature, and we were able to verify the most frequently used evaluation indices in these categories. The results of this study will be used to establish evaluation indices for the treatment of TKR in the future using Korean medicine.

In this study, we investigated the effects of five EMS lumbar back pressure belts produced on an anatomical basis on lumbar spine stabilization. Five core muscles were selected, including the urinal, vertebral column, endotracheal, external abdominal, and large back muscles, and patterns were designed using a conductive fabric considering the appropriate muscle shape and pain-causing points. We experimented with four motions to examine the effects of different EMS abdominal compression belts on lumbar spine stabilization. Five healthy men in their 20s were selected. The selection conditions include no back pain history for the past three months, no restricted movements through pre-inspection, and the muscular strength of the body should belong to the normal grade. Using SLR, the sequence of experimental actions was chosen from the following but not limited to left-hand, body-hand, and back-line forces. Resting between movements lasted for 2 min, and the experiments were conducted after wearing the EMS abdominal pressure belt. Electrical stimulation was applied for 10 min to increase blood flow and muscle activation. The statistics of the experimental results were analyzed for specific differences by conducting the Wilcoxon and Friedman tests with nonparametric tests. The ranking results of each pattern were successfully assessed in the order of 5, 4, 3, 1, 2 for the five patterns, and we could identify slightly more significant results for experimental behavior associated with each muscle movement. Patterns produced based on anatomy showed differentiated effects when electric stimulation was applied to each muscle in different shapes, which could improve the stabilization of the lumbar spine in everyday life or training to the public. Based on these results, subsequent research would focus on developing smart healthcare clothing that is practical in daily life by employing different anatomical mechanisms, depending on the back pain, to utilize trunk-type tights.

This retrospective observational study was aimed to evaluate that Daoyin Exercise therapy improves the symptoms related to lumbar disc herniation. We analyzed the medical records of 7 patients, who satisfied with inclusion and exclusion criteria. The subjects of the study were the patients who were prescribed Daoyin Exercise Therapy and Korean medical treatments for lumbar intervertebral disc herniation at Dunsan Korean Medicine Hospital of Daejeon University from July 25th, 2016 to March 31th, 2017. The effects of Daoyin Exercise Therapy was evaluated by comparing before and after taking Daoyin Exercise Therapy through 0-10 Numeric Rating Scale(NRS), Roland & Morris Disability Questionnaire(RMDQ), Trunk Extension Flexion(TEF) Program, EuroQol five Demension Questionnaire(EQ-5D, EQVAS) of the symptoms including lower back pain. The Daoyin Exercise Therapy combined with Korean medicine treatment reduced NRS($3.357{\pm}3.038$) and RMDQ($9.50{\pm}6.364$), and improved Muscle endurance($44.429{\pm}45.136$), EQ-5D($0.09{\pm}0.12$) and EQVAS($6.571{\pm}19.260$) of the 7 patients without side effects. These results implied that Daoyin Exercise Therapy might helps to improve symptoms of patients with lumbar disc herniation by reducing the symptoms of lower back pain and improving muscle endurance, quality of life, strength enhancement and core muscles.

This study was understood the risk mechanism of falls in the elderly and reviewed previous research data to see if the principle of Pilates rehabilitation exercise could have a positive effect on balance ability and postural stabilization in the elderly, and the purpose of this study is to present literature-based data on the fall prevention effect of rehabilitation Pilates exercise. First, the rehabilitation Pilates exercise makes it available for strengthening the center of the body to stabilize the spine and pelvis and stimulates the nerve root, thereby having an effect on the balance and the joint stabilization. Second, a proprioceptive sensory impairment and a musculoskeletal degenerative disease due to aging increase the loss of balance ability and the instability in posture maintenance, thereby coming to raise the risk of a fall damage caused by the difficulty in performing motor functions and by the gait disturbance. Third, the rehabilitation Pilates exercise leads to improving the core muscle strength in older adults, resulting in being capable of expecting the betterment in the balance and the reaction time motor function. And there is a positive impact on the improvement in body imbalance and on the stability in movement involved in the fall prevention, resulting in being able to suggest the possibility of likely contributing to a reduction in a fall risk rate. In conclusion, the rehabilitation Pilates as the elderly exercise program showed effects on the improvement in the body's muscular strength, on the upgrade in a sense of balance, and on the stabilization of core. Thus, it was considered to diminish the risk factors for a fall damage caused by musculoskeletal degeneration and to be capable of preventing a serious disorder of activity due to a chronic senile disease.

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.
