Abstract

Most studies related to footwear together with electromyographic or ground reaction force were conducted on squat, however, there were limited studies conducted with deadlift. Therefore, this study aimed to compare between barefoot and running shoe with high and low loads on deadlift performance among young adults. Twenty-two male participants (Age: 19.7 ± 1.5 years; Bodyweight: 74.4 ± 7.9 kg; Height: 172.1 ± 6.1 cm; Deadlift 1RM: 148.3 ± 21.7 kg; Deadlift experience: 1.98 ± 1.68 years) were recruited for a randomized cross over experimental trials (barefoot and running shoe conditions) with high and low loads. The experimental trials included of 4 sets of warm up with 5, 3, 2, and 1 repetition at 35%, 50%, 60%, and 70% of 1RM of deadlift followed by the deadlift test at either high or low load with barefoot or running shoe condition. Results showed that there were no significant difference in electromyographic for all Vastus Lateralis, Biceps Femoris, and Erector Spinae between barefoot and running shoe as the differences were approximately 2% - 12% (p>0.05). The running shoe with low load trials has a higher ground reaction force than the barefoot with low load in the first repetition by 1.8% (p=0.041). However, there were no significant difference in other footwear conditions. In conclusion, barefoot and running shod deadlift did not show any differences in electromyographic and ground reaction force while performing a deadlift.
