The “sticking point” in weightlifting represents the point in the movement where there is a disproportionate increase in difficulty that often results in compensation and lift failure. Understanding the various biomechanical and physiological factors that lead to sticking points has a significant role in injury prevention and strength rehabilitation. For this reason, the authors of the present study sought to consolidate our current understanding on three benchmark exercises: the deadlift, bench press and squat.
Overall, it was shown that when comparing muscle activity across individuals, there was no significant change in the electromyographic (EMG) patterns around the sticking points. Furthermore, the location of the sticking point varied significantly within the individual movements and depended largely on the different mechanics and lifting styles (for instance conventional deadlift versus sumo deadlift).
