Purpose: The purpose of this study is to determine changes to the abdominal muscle activity, after Plank exercise and Hip walking exercise and to compare the effects of the two exercise methods. Methods: Thirty-two subjects were randomly assigned to either a Plank exercise group (n=16 ; 8 male and 8 female) or a Hip walking exercise group (n=16 ; 8 male and 8 female). Plank exercise was performed five times per week during 6 weeks. The first week was performed 3sets a day(1set program; 30 second hold-30 second rest), and then increased by 1set per week. Hip walking exercise was performed for 30 second, once a day, five times per week, during 6 weeks. The muscle activities of abdominal muscles(external oblique, rectus abdominis) were measured before, after 3 weeks and after 6 weeks of exercise by using a wireless surface electromyogram(EMG). The normalized EMG activities were compared using a one-way repeated ANOVA, and if there is statistically significant difference, a Bonferroni was used as post-hoc. Independent t-test was used to compare differences between groups. All statistical significance level was set at p<.05. Results: The results of this study were as follows. In both groups, there were a variation of abdominal muscle activities. It has been increased significantly after exercise more than before. To be specific, the activity has been increased more 6 weeks later than 3 weeks. But there was no significant difference between the both groups. Conclusion: These results suggest that plank exercise and hip walking exercise can be useful method for people to increase muscle activity in a short time, regardless of place.

Purpose: The purpose of this study was to investigate the effects of core muscle strengthening training and core exercise on unstable support on the balance and posture alignment of 20s healthy college student METHODS: twelven college student were randomly assigned to perform core muscle training for six college student, and six college student were exercised on an unstable surface. Two groups were conducted three times a week for 30 minutes. Dynamic balance and posture alignment were measured before and after the experiment. Results: There was a statistically significant difference dynamic balance and posture alignment in the group trained on the unstable support surface (p<.05). Conclusion: Based on the results of this study, exercise on an unstable support surface is an effective method for improving posture alignment and dynamic balance in healthy adults in their twenties.

Purpose: This study is to see if the calf muscle movement affects the length of stride, symmetry, and ability to overcome obstacles, and muscle activity in patients with hemiplegia. Methods: Electromagnetic signals were first measured by ankle plantar flexion or muscle testing in a supine position with 12 patient ankle plantar flexor in the standing position. In the second measurement, the length and symmetry of stride are measured through the gait analyzer. In the third measurement, the ability to measure obstacles was measured. The paired- T test revealed a significant difference. Results: After the intervention, the step length was significantly decreased (p<.05), while the speed and failure rate of the obstacle overcoming was significantly decreased (p<.05). also muscle actvitiy was significantly increased (p<.05), and muscle power was significantly increased (p<.05). the different was statistically significant between pre- and post-intervetion. but after intervention, the gait symmetry was no significantly difference (p>.05), between pre- and post-intervention. Conclusion: The results of this study show that the length of stride, ability to overcome obstacles, muscular activity, and muscle strength are increased more after exercise. Therefore, it is a movement that requires patients with hemiplegia to aim for calf muscle exercise because it increases the length of step in their daily lives, overcomes obstacles, and has a positive effect on muscle activity and muscle strength.

Purpose: The purpose of this study was to investigate the effect of the application of spinal support device with core stabilization exercise on the pain and low back dysfunction of office workers with non-specific low back pain (NSLBP). Methods: This study was conducted with 50 office workers with NSLBP. Participants were randomly assigned to the intervention and control groups. Both groups performed core stabilization exercise and bed rest for three times a week for 4 weeks, and the intervention group used a spinal support device for bed rest. The primary outcome was pain, and the secondary outcome was low back dysfunction and satisfaction. Measurements were performed pre and post intervention. Results: As a result of the study, the intervention group showed a significant improvement in resting pain, working pain, pain pressure threshold (PPT), and low back dysfunction (p<.05), however, the control group only showed significant improvement in resting pain, working pain, low back dysfunction (p<.05). In comparing the changes between groups, the intervention group showed a significant improvement in working pain, PPT of quadratus lumborum than the control group (p<.05). After intervention, treatment satisfaction was significantly higher in the intervention group than the control group (p<.05). Conclusion: Based on the results of this study, the application of the spinal support device with the core stabilization exercise is considered as an intervention that can provide a positive effect on working pain and PPT in office workers with NSLBP.

Purpose: The purpose of this study is to investigate the cardiopulmonary endurance and the energy metabolism of obese male college students group and normal male college students group of graded load exercise using lower cycle ergometer. Methods: Targeting 15 obese male college students and normal male college Students, an graded load exercise was performed with the use of lower cycle ergometer by increasing 20 watts every 2 minute and ERS 2.0 system were used for the cardiopulmonary function and the energy metabolism. Results: The obese college student group showed significantly lower results in cardiopulmonary endurance in maximum oxygen intake and per minute ventilation, and in energy metabolism, body metabolism and maximum energy consumption were significantly lower than in the normal college student group. Conclusion: Therefore, the decrease in cardiopulmonary endurance in obese college students can act as a negative factor that increases the risk of cardiovascular disease and the prevalence of various disease in the future, so it is necessary to manage cardiopulmonary function and energy consumption metabolism through active weight management and exercise.

Purpose: The purpose of this study is to inverstigate the changes in muscle synergy and muscle weightings during sqaut exercise on different ground slopes and propose the goal-directed squat exercise as a rehabilitation method. Methods: Tweleve healthy young adults with an average age of 21.45 ± 1.03 years, and body mass index of 24.21 ± 4.01kg/m2 performed squat exercises on 3 different slope boards(i.e. flat, 10-degree incline, 10-degree decline ground slope). The squat exercise on each ground slope condtion was performed 10 trials with a rest time of 30 seconds between the conditions. During the squat exercise, muscle activation of tibialis anterior (TA), multifidus (MUL), gastrocnemius (GCM) and internal oblique (IO) muscles were measured and included in muscle synergy analysis using ICAPCA. Results: As a result, three synergies of all participants were extracted and there was no significant difference in variance accounted for(VAF) of each synergy, indicating the complexity of muscle synergy between the ground slope condition. However, during exercise on the incline slope ground, there were sigfniciant lower TA muscle weighting of synergy 1 (P=0.020) and higher IO muscle weighting of synergy 2 (P=0.005) than flat ground. Furthremore, during exercise on the decline slope ground, a significant lower TA muscle weighting of synergy 2 (P=0.017) was found when compared with the incline slope ground. Conclusion: In conclusion, the findings of this study suggest that squat exercise on incline slope ground will be recommended for training lower extremity muscles above the ankle and abdominal core muscles, and decline slope ground will be recommended for training balance abiltiy, especially, in the elderly.

Purpose: For rational selection of major capability according to the characteristics of college faculties and departments related to sports exercise rehabilitation, through previous studies and current policies, we proposed a plan to train professionals in the field of motor rehabilitation for developmental rehabilitation services desired by society, and present leading indicators. Methods and Results: By the qualification regulations of personnel providing developmental rehabilitation services, it is divided into 9 areas: hearing, art, music, behavior, play, psychology, sensory, motor rehabilitation, and rehabilitation psychology. It was specified that curriculum of each area must be completed, and in 2014 year, 531 different types of private qualifications, registered with the Korea Vocational Competency Development Center were named as language rehabilitation services, and professionalism was obtained by unifying them into national qualifications. It is being promoted so that 13,100 specialists in each area can receive specialized rehabilitation in each area. Conclusion: In the case of a department of health, exercise and rehabilitation, the curriculum is needed to be reorganized by adding subjects for course evaluation because there are many intersections with the subjects completed in the field of motor development and rehabilitation of developmental rehabilitation services. In addtion, most field of study already covered in the university, it will be beneficial for the department, students, and social level as well after the reorganization.

Purpose: In this study, by synthesizing and summarizing previous studies, related to major preference and satisfaction, targetting at students enrolled in health and medical departments of university, factors to enhance the admission competitiveness of health departments in university were identified. Furhermore, based on the review, strategies for future admissions resources and student recruitment were proposed. Methods: In the review, the period of selection for the university entrance examination was mostly determined during the first semester of the third year of high school, and information about the entrance examination was mainly obtained from the Internet and from the university entrance examination guidelines. In addition, the motivation for applying for health-related departments was the employment rate and individuality the most, but in the case of students who entered school thinking only about employment, their satisfaction with college life was not higher than that of those who entered after considering their aptitude. Resutls: Students who entered with personal goals such as talent and aptitude showed a high tendency to be satisfied with school life. In addition, during college life, students who were lack of the information about their career path or the understanding of their major reported that their career preparation activities were also poor. Conclusion: In conclusion, based on the review of this study, the common motivation and opinion of students to select the major related health and medicine field were grasped and the importance of early college advertising was identified in terms of enhancing the satisfaction of college life as well as securing the future admission resource. Furthermore, a variety of media to provide informations about career path will be necessary to increase career preparation activities of students.
