Abstract

Weightlifting technique used by many team sport athletes differs from that of competitiveweightlifters. Specifically, between the first and second pull, the double knee bend (DKB)involves an unweighting phase wherein the knees are flexed before extension in the second pull.Proficiency in this technique may be the primary mechanism by which weightlifters producelarge vertical ground reaction force (GRF) peaks and rates of force development (RFD). Thepurpose of this study was therefore to evaluate differences in GRF during cleans with andwithout the DKB. GRF were measured during performance of 80%1RM cleans by 10experienced weightlifters with or without the DKB. Paired samples t-tests revealed greater forcereduction during unweighting (d=2.85), and greater RFD (d=2.30) in the second pull with theDKB compared with no DKB. Our findings suggest that the use of the DKB during training ofthe clean exercise may provide a greater power-specific training stimulus
