Pull-ups are a common training exercise essential for muscle growth in resistance-based training workouts and workout programs. The purpose of this study was to determine the impact of different pull-up grips on muscle activation in six college aged males. Participants were fitted with electrodes on the biceps brachii, middle deltoid, trapezius, and the latissimus dorsi. Maximum voluntary isometric contraction (MVIC) values were assessed for each muscle. Participants completed five trials of each pull up grip variations for sEMG assessment. Grip variations included pronated grip, neutral grip, and supinated grip. A two minutes rest period was given between each grip variation. Mean EMG activation was normalized to MVIC values for each muscle and standard deviation was also calculated. Data will be analysis is ongoing.
