The aim of this study was to determine whether athletes of higher relative strength maximise their power output at higher percentages of their 1 RM in the power clean. Twenty-nine male athletes (power clean 1 RM = 99.2 ± 18.9 kg) performed two power cleans at 10% increments from 50% to 100% of 1 RM. Bar displacement was collected by a Ballistic Measurement System (BMS) and power output was calculated using system mass (SM) and bar mass (BM) methods. Optimal loads were 50% and 90% for the SM and BM methods respectively. However, a limitation of the study was that loads below 50% of 1 RM were not examined. Relative strength was not related to percentage of 1 RM at which maximal power output was achieved.
