Weightlifting coaches can evaluate kinematic and kinetic variables to enhance their feedback and instruction and to optimize a periodized training plan. These coaches should be particularly interested in peak barbell velocity during the weightlifting movements (snatch, clean, and jerk), as it is an important determinant of weightlifting performance (Bartonietz, 1996). Existing research has identified sex-based differences among several variables related to weightlifting performance, such as strength (Stone et al., 2005), power (Garhammer, 1991; Gourgoulis et al., 2002; Harbili, 2012), and peak barbell velocity (Gourgoulis et al., 2002; Harbili, 2012). While many factors contribute to sex-based performance differences in weightlifting (see also Storey & Smith, 2012), comparative analysis using a common weight class obviates the influence of body mass on such differences. The present study examined the performances of men and women at the 2015 IWF World Championships (Championships). This study's purpose was to provide a reference of the current status and trajectory of sex-based peak barbell velocity differences in weightlifting in order to guide practitioners in prioritizing the training emphases of weightlifters.
