Purpose : The purpose of this study was to find out the effects on muscle activations of serratus anterior and upper trapezius muscles when push-up plus exercise togu applied differently depending on the body part. Method : Thirty six volunteers took part in this study and we divided into three groups(upper arm togu group 12, leg togu group 12, upper arm-leg togu group 12). Each experimental group performed push-up plus exercise. All volunteers received a total of 18 exercise session over a 6 week period (three times per week). Exercise program was composed of serratus anterior and upper trapezius push-up plus exercise. Then we measured muscle activation of scapular stabilizer by electromyography. Repeated ANOVA was used to examine the effects of the intervention on each outcome measure. Result : After the six week intervention, there was a significant difference between the pre and 6 week in serratus anterior and upper trapezius muscle activity(p<0.05). After the six week intervention, there was a significant difference among the three group in serratus anterior muscle activity but no significant difference in upper trapezius muscle activity(p>.05). Conclusion : Serratus anterior and upper trapezius showed high muscle activity during push-up plus exercise. Therefore have a positive impact of scapular stabilizer. The larger the area of the unstable support surface, the larger muscle activity was larger of variation quantity.

Purpose: The purpose of this study is to find and compare the differences between muscle activity change and balance during unstable support and weight load during the squat exercise. Methods: The subjects were 36 normal adults (18 male and 18 female). It was randomly divided into a stable support group (control group), an unstable support group (experimental group 1), and an unstable support surface weighted group (experimental group 2), and the squat exercise was performed for 4 weeks. Togu jumper (TOGU, Germany) was applied as the unstable support surface, and 4 kg of Kettlebell (Schmidt, China) was applied for the weight load. The squat exercise was conducted three times a week and consisted of 10 minutes of warm-up, 20 minutes of the main exercise, and 10 minutes of down exercise. This exercise was repeated three sets of 15 squats. Results: The result is as follows. First, changes in muscle activity according to the experimental period increased in both the stable and unstable support groups and the unstable support and the largest increase in the weight load group (p<.05). Second, change in the balance ability according to the experiment period was most improved in the unstable support according to the experiment period in the change of Endpoint excursion (EPE) and the Directional control (DCL) than the other two groups (p<.05). Conclusion: Squat exercise is effective as an exercise to improve the strength and balance of leg muscles. As in previous studies, it was found that exercise is more effective on the unstable support than on the stable support and that it is most effective to give weight load on the unstable support.

Purpose: This study assessed the effects of major selection and major satisfaction levels on university life adaptation among health students. Methods: This study included 300 first- and second-grade college students attending classes for physical therapy, occupational therapy, and dental hygiene at K University in Busan Metropolitan City. We assessed their motivations regarding major selection and its influence on their adaptation to school life through a mobile questionnaire applied for 6 weeks between October 30 and December 9, 2018. Data from 200 respondents were included in the analysis after excluding data deemed to have been provided insincerely and questions without responses. Correlation and multi-cycle analyses were performed using SPSS version 25.0 to test the data collected. Results: The choice and satisfaction with the major selected were significantly associated with college life. Outdoor motivation was among the factors that less affected academic, social, and personal-emotional adaptation, which are sub-factors of university life adaptation. Among the factors that less affected the satisfaction level, curriculum satisfaction and awareness satisfaction affected academic adaptation; general satisfaction, curriculum satisfaction, and relationship satisfaction affected social adaptation; relationship satisfaction and awareness satisfaction affected personal-emotional adaptation; and curriculum satisfaction and relationship satisfaction affected environmental adaptation. Conclusion: The results of this study confirmed that the choice and satisfaction with majors were an important variable in predicting adaptation to college life. Thus, increasing the adaptation of university students requires educational services related to major satisfaction and social awareness, as well as a trust-based system for maintaining emotional ties.

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 study aimed to investigate the effect of ergometer exercise after performing static stretching and strength exercise on the activity of the quadriceps muscle. In general, the effects of performing both the strength and stretching exercises before ergometer exercises were examined. Methods: The participants were divided into two exercise groups and performed static stretching and strength exercises and then ergometer exercise. Each exercise was performed for 4 weeks, three times a week, by each group to measure changes in the muscle activities of the rectus femoris, vastus lateralis, and vastus medialis. Measurements were made at weeks 0 and 4, and electromyography was used in a static posture. Results: Both the stretching and strength exercise groups showed significant increases in the rectus femoris, vastus lateralis, vastus medialis muscle activities after exercise. Conclusion: Stretching and strength exercises before ergometer exercise helps to increase muscle activities. Stretching is thought to be more effective for gaining muscle activity than muscle strength. However, no significant difference was found between the two groups.

Purpose : Forward head posture is typical neck disorders occur in all people. And this attitude causes a shortening and weakening of the muscles in the body. It also causes excessive extension acts as a reward. This attitude has to change if the pain occurs around the neck and shoulders, and are subjected to unusual stress. Patients with chronic neck pain associated with forward head posture was found to be the more severe the fall of the respiratory, forward head posture poor quality of much breath. The purpose of this study was to compare the effect of changes in forward head posture and neutral head posture on respiratory. Method : Forty volunteers were participated in study and divided into two groups [forward head posture group (n=20) and neutral head posture group (n=20)]. We measured cervical alignment with global postural system to find out a forward head posture. Respiratory function was measured with a SPIROVIT SP-1 equipment and we found out a forced vital capacity (FVC), forced expiratory volume at one second (FEV1) and FEV1/FVC. A pared t-test was used to determine a statistical significance for the pulmonary function variation and a independent t-test was used to determine a statistical significance in the two groups. Results : In the experimental group, FVC and FEV1 were significantly higher in the artificial neutral head posture than in the forward head posture. In the control group, FVC and FEV1 were significantly higher in the neutral head posture than in the forward head posture. FVC, FEV1, and FEV1/ FVC were significantly higher in the neutral head posture of control group than the artificial neutral head posture of experimental group and higher in the artificial forward head posture of control group than the forward head posture of experimental group. Conclusion : In conclusion, neutral head posture is considered to be an important factor in correct posture and improvement of lung function and continuous study of posture correction program for posture imbalance will be needed.
