| Summary: | This study was conducted to compare the electromyographic (EMG) activation and number of repetitions completed during traditional, hammer and reverse dumbbell bicep curl among trained men. A total of thirty trained men that are physically active and have at least one year of experience in fitness training and have good techniques in bicep curl exercises were recruited as study participants. Participants were required to perform all three types of bicep curl exercises in a randomized order to avoid bias in the exercise sequence. EMG readings of biceps brachii and brachialis were recorded to be analyzed. The number of repetitions was also recorded for performance data output. The results showed that the EMG activation of biceps brachii was highest during the traditional bicep curl exercise followed by hammer and reverse curl. In contrast, it was found that brachialis muscle was significantly greater activated during reverse curl compared to hammer and traditional bicep curl. The number of repetitions was greatest during hammer curl, followed by traditional and reverse curl. It is recommended for the trained men to include variations in performing bicep curl exercises due to different stimuli for the muscles that may affect long-term adaptations to specific muscles. © 2024 Author(s).
