The purpose of this study was to investigate the trunk and lower extremity muscle activity induced by three different intensity conditions (intensity 1, 3, 5) of whole body vibration (WBV) during bridging exercise. Surface electromyography (EMG) was used to measure trunk and lower extremity muscles activity. Eleven healthy young subjects (6 males, 5 females) were recruited from university students. The collected EMG data were normalized using reference contraction (no vibration during bridging) and expressed as a percentage of reference voluntary contraction. To analyze the differences in EMG data, the repeated one-way analysis of variance was used. A Bonferroni's correction was used for multiple comparisons. The study showed that EMG activity of the rectus abdominis, external oblique, internal oblique, erector spinae and rectus femoris muscles was not significantly different among three intensity conditions of WBV during bridging exercise (p>.05). However, there were significantly increased EMG activity of the medial hamstring muscle (p=.001) and medial gastrocnemius muscle (p=.027) in the intensity 3 condition compared with the intensity 1 condition. This result can be interpreted that vibration was absorbed through the distal muscles, plantar flexor and knee flexor.

The purpose of this study was to develop the ESD program related to creative-experience activity, and to examine the effect of its application. The program was composed of 13 sessions for fifth-grade class in elementary school, including all of the environmental, economic, and social aspects of ESD. This program was connected to the domains of creative hands-on activities, that is, career activities, club activities, self-regulated activities and voluntary service activities. The results was as follows. First, the experimental group to undergo the ESD program related to creative-experience activity did not show significant differences in environmental literacy compared to the control group, but it is proven that this program contributed to the improvement of learners' environmental emotion, skill, and participation. Second, the experimental group did not show significant differences in scientific attitude compared to the control group, but it was considered to affect the elementary students' criticism, self-esteem, and patience in positive and effective manner. In conclusion, more ESD program that cultivate elementary school students' environmental literacy need to be developed continuously, and more intensive research should be conducted to earn better understanding of ESD.

PURPOSE: The purpose of this study was to investigate any changes in abdominal muscle activity after curl-up and jack-knife exercisse using a sling and swiss-ball. METHODS: Sixteen asymptomatic subjects were randomly assigned into either a sling exercise group (SG) or swiss-ball exercise group (SBG). Subjects performed curl-up and jack-knife exercise using sling and swiss ball. Activity of abdominal muscles (rectus abdominis and external oblique) was assessed using surface electromyography (EMG) and normalized maximal voluntary isometric contraction (MVIC) before and after exercises. The significance of differences between the SG and the SBG was evaluated by analysis of covariance (ANCOVA). RESULTS: There was an increase in activity of all abdominal muscles after the curl-up and jack-knife exercises for 6 weeks. However, there was not a significant difference between the SG and the SBG after curl-up exercise (p>.05). There was also not a significant difference between the SG and the SBG after Jack-knife exercise (p>.05) except for the right external oblique muscle (p<.05). CONCLUSION: Exercises on an unstable surface using a sling and swiss ball are effective ways of abdominal muscle exercise.

Purpose: The purpose of this study was to examine the electromyographic (EMG) activity of the abdominal muscles and to compare the activity ratios of the bilateral rectus abdominis (RA) to oblique abdominal muscles during shoulder abduction in opposite directions with single leg raising (SLR) performed in the supine position on a foam roller. Methods: Fifteen healthy subjects were recruited to the study. Each subject lay on the foam roller and performed left single leg raising with right or left shoulder $90^{\circ}$ abduction (Abd); performed in a random order. Surface EMG recordings of selected abdominal muscles (i.e., the RA, external oblique abdominis [EO], internal oblique abdominis [IO], and transverse abdominis [TrA]) were normalized to maximum voluntary isometric contraction. EO/RA and IO and TrA/RA ratios were determined with surface EMG. Data were analyzed by Independent t-test. The statistical significance level was p<0.05. Results: The results were as follows: (1) the right RA, left EO, and right IO and TrA muscle activities increased significantly at the left SLR with left Abd compared to the left SLR with right Abd (p<0.05); and (2) the ratio of right EO/RA activity increased significantly at the left SLR with right Abd compared to left Abd (p<0.05). Conclusion: These findings suggest that left SLR with left Abd on a foam roller is an appropriate exercise for activation of specific oblique abdominal muscles.

Purpose : This study was performed to distinguish the muscle activation of vastus medialis and biceps femoris through open and closed kinetic chain exercise. Methods : 31 healthy male and female students in Daegu Health College were participated in this study. All subjects were conducted three types open and closed kinetic chain exercises to examine muscle activity during the last four seconds using the sEMG system. Collected EMG data were normalized using the maximal voluntary isometric contraction(MVIC). Results : MVIC of each muscle was showed significantly increased(p<0.5). In the case of open chain exercise, the type 3 exercise most increased than type 2 and 3 exercise in vastus medialis than biceps femoris muscle. The closed chain exercise presented type 6 exercise most increased than type 4 and 5 exercise in biceps femoris than vastus medialis. Conclusion : This study finally proved that muscle activity which maintains stability of knee differ from depending on the types of exercises. Therefore, the combination of the two chain exercises is believed to greatly contribute to increments in muscle activity.

Purpose: This study examined the effect of the degree of neck flexion on the muscle activity of the upper trapezius and sternocleidomastoid muscles in the sitting position. Methods: Twenty-five healthy young adults participated in this study. The study was designed to compare the muscle activity of the upper trapezius and sternocleidomastoid muscles according to the neck flexion angle under the three conditions (neutral position, 15° neck flexion, and 45° neck flexion) in the sitting position. During the neck position of three conditions in sitting, the electromyography (EMG) data (% maximum voluntary isometric contraction) of the muscles were recorded using a wireless surface EMG system. Results: The muscle activity of the upper trapezius muscle and the sternocleidomastoid muscles showed a significant difference according to the three-neck position conditions (p<0.05), and in the post-hoc test results, both muscles showed significant differences between the neutral position and 15° flexion, the neutral position and 45° flexion, and the 15° flexion and 45° flexion, respectively. Conclusion: The load on the muscles around the neck and shoulders increased as the neck flexion angle increased. This suggests that performing various daily activities and tasks with the neck as neutral as possible can prevent muscle fatigue or musculoskeletal disorders.
