Abstract
The purpose of this study is to analyze the effectiveness of the automatic stepper and changes in lower extremity muscle activity through step by step exercise. The subjects were 18 male university students. Two groups of 9 students were made and they each proceeded 5 and 10 levels of automatic stepper exercise to analyze rectus femoris, biceps femoris, tibialis anterior and medial gastrocnemius. The analysis was used to find out the changes in lower extremity muscle activity using the EMG at 10, 20 and 30 minutes after the exercise. The mean and standard deviation of all data were calculated using the SPSS 24.0, and one-way ANOVA with repeated measure was performed to verify the difference in the mean between time periods for measurement variables. In the case of inter-period significance, the LSD method was used for the post-hoc test, and the statistical significance level was set to α=.05. In future research, an in-depth study of various variables through a regular exercise program for the elderly, disabled, and patients who need to exercise safely will be required.
