Background/Objectives:The purpose of this study is to identify changes in the muscle activity of the trunk and lower extremity during deadlift with various equipments (Kettlebell, Barbell, and Trap bar).
Method/Statistical Analysis:29 people were selected to measure the muscle activity of the elector spinae, gluteus maximus, rectus femoris and rectus abdominis. One-way ANOVA with repeated measurements was conducted to determine the difference in muscle activity in various deadlift. The Bonferroni correction was used as a post-test to check the difference in muscle activity between the variousinterventions, and the significance level was set to 0.05. Statistical programs used SPSS Version 22.0 (Statistics Package for the Social Science).
Findings:There were significant differences in elector spinae, gluteus maximus,and rectus during the various deadlift.The rectus femoris showed higher muscle activity in trapbar deadlift than barbell deadlift and kettlebell deadlift. The elector spinae showed higher muscle activity barbell deadlift than kettlebell deadlift. The gluteus maximus showed higher muscle activity in barbell deadlift and kettlebell deadlift than deadlift.
Improvements/Applications:This study suggests thatmuscle activity vary depending on the barbell during deadlift.

Background/Objectives:The purpose of this study was to evaluate the relationship betweenStar Excusion Balance Test(SEBT), Y-Balnce Test(YBT) and Visual Feedback Balance Test(VFT).
Method/Statistical Analysis:Thirty subjects were recruited for this study. To verify the usefulness of the VFT, we compared the correlation with the existing SEBT and YBT scores.Pearson Correlation Analysis was conducted to determine the difference in each balance test.
Findings: In this study, there were statistically significant correlations between reach distance and composite scoresin SEBT, YBT and VFT(p<0.01).
Improvements/Applications:The results suggest that VFT may be able touse dynamic test equipment. The VFT can be used for dynamic balance exercise because it can intuitively visually check balance values.
