PURPOSE : The purpose of this study was to investigate the side plank exercis e effect on the muscle activity of core muscles. After performing exercise by ap plying each sling position differently to the side plank exercise, the muscle activi ty of External obilique abdominal muscle(EO), Internal oblique abdominal muscle (IO) and Rectus abdominal muscle(RA) was compared. It was intended to lay th e foundation for presenting more efficient exercise methods to subjects in need of strengthening abdominal muscles. METHOD : The subjects of this study were 30 healthy adults (15 men and 15 women) and were randomly and equally assigned to three groups by a random n umber table. All subjects were divided into three groups according to the side pl ank exercise method. side flank (Group A = general side plank, Group B = knee sling side plank , Group C = ankle sling side plank). The side plank exercise was performed three times a week for 4 weeks for 1 minute and 50 seconds. We had pre-post measurements of trunk muscles(EO,IO,RA). All measured data were compared and analyzed as follows. Measure the corresponding table number T test and repeat measurement ANOVA and one-way ANOVA. The statistical significance level is set to 0.05. RESULT : The results of this study are as follows: 1. There were significant differences in the External obilique abdominal muscle(EO) and Rectus abdominal muscle(RA) in all groups 2. Compared to other conditions, there was significant muscle activity when wearing slings at the ankles (p<0.05). CONCLUSION : The trunk muscle activity was the most effective when exercising the ankle sling side plank. As a result, when the lever was exercised on the longest and unstable support, the greatest effect was seen. It can be seen that the long and stable support surface has a better effect than the short and unstable support surface.

Background : Standards for preventing skin damage caused by physical and chemical stimulation of tape have been needed. Objective : The purpose of this study is to investigate the degree of skin irritation of taping over time and the appropriate application time. Methods : The skin reactivity was evaluated after we removed the tape at the inside of the upper arm after 1 hour, 4 hours, 12 hours, and 24 hours. Result : Four hours later, all participants had even a mild symptom of redness. Until 4 hours after taping, half of participants feel mild itching, but There were no more serious symptoms. However, waiting for 12 hours, two participants who felt mild itching complained moderate symptom and when we wait for 24 hours, two asymptomatic participants complained mild symptom. During study, 30% of participants felt burning sensation in the contact area overall six participants complained of tightness. and ,among them, four of participants felt it after 12 hours and the rest felt it after 24 hours. Conclusion : To lower the probability of adverse skin reactions,If it is difficult to accurately determine the skin condition,we thought that limiting the taping to about 4 hours is recommended.

PURPOSE : In this study, when cranio-cervical flexion exercise with shoulder calibration aid were applied to the forward head posture subjects, the changes in the craniovertebral angle, sternocleidomastoid, and deep cervical flexor muscles were analyzed. METHOD : For 4 weeks, a total of 36 experimenters were divided into 3 groups, with group A applying shoulder calibration aid, group B applying cranio-cervical flexion exercise, and group C applying shoulder calibration aid and cranio-cervical flexion exercise together. The craniovertebral angle was photographed with a camera at the angle of C7 and tragus, and the muscle thickness was measured with an ultrasonic device. RESULT : Depending on the period, there was a significant difference between the craniovertebral angle and the deep neck flexion muscle thickness before and after intervention, but there was no significant difference between the groups, and there was no significant difference between the sternocleidomastoid before and after intervention. CONCLUSION : The cranio-cervical flexion exercise and shoulder calibration aid are applied together to increase the craniovertebral angle and the muscle thickness of the deep neck flexor over time during the intervention of the forward head posture subject.
