Optimal Power Clean Resistance for Producing Maximal Power Output

Abstract

1434 Studies on traditional resistance training (e.g., bench press, squat, bench throw, squat jump) indicate that to increase maximal power output (PO) athletes should train at the velocity and resistance which maximizes PO. Research demonstrates that maximal mechanical power is produced at a resistance of 30% of maximum isometric strength which corresponds to a velocity of muscle shortening, approximately 30% of maximum. However, to date there has been little research on the optimal resistance for producing maximal power when executing olympic lifts (e.g., power clean, snatch). PURPOSE: This study was designed to determine the optimal resistance for producing maximal PO when executing the power clean (PC). METHODS: Ten college-age, resistance trained males performed a 1-repetition maximum (RM) PC. PO in watts was collected using the Ballistic Measurement System (BMS). A rotary encoder attached to the BMS and interfaced with the computer. One week later, subjects performed PC repetitions at 25, 40, 55, 70, 85% RM. RESULTS: Mean and SD values for each percent RM are presented in the table below. With the exception of the 85% RM and 70% RM interval, all mean PO were significantly different (p<.05) from each other. CONCLUSION: In contrast to research on traditional resistance training which demonstrate that maximum PO is produced at a resistance around 30% of maximum, results from this study indicate that PO for the PC were the highest at or near 1-RM values. Thus, optimal PC resistance for producing maximal PO is at or near 1-RM.Table: No Caption available.
