Abstract
Objective: The purpose of this study was to evaluate 16 muscles activity according to three exercise intensity when performing Deadlift and Upright row. Method: To accomplish the purpose of the study, subjects (n=10) were performed Electromyography (EMG) measurement for 16 different muscles. The experimental movements were Deadlift and Upright row, measured five times for each intensity (40%, 60%, 80%) of 1RM. This study normalized the EMG values through RVC for comparative analysis. Results: The results were summarized as follows: As a result of Deadlift, there was significant difference in the mean EMG value according to the exercise intensity in all muscles except RA, PM and BB (p<.05). As a result of Upright row, There was significant difference in the mean EMG value according to the exercise intensity in all muscles except BF, TA, GN, RA and UT (p<.05). Conclusion: This study allowed us to know the activities of major muscles according to the exercise intensity for 16 different muscles when performing Deadlift and Upright row.
