To compare the acute effects of back squats and power cleans on sprint performance.


Thirteen elite junior rugby league players performed 20-m linear sprints before and 7 min after 2 different conditioning activities or 1 control condition. The conditioning activities included 1 set of 3 back squats or power cleans at 90% 1-repetition maximum. A 2 × 2 repeated-measures ANOVA was used to compare preconditioning and postconditioning changes in sprint performance.


Both the back-squat and power-clean conditioning activities demonstrated a potentiation effect as indicated by improved sprint time (back squat: P = .001, ES = –0.66; power cleans: P = .001, ES = –0.92), velocity (back squat: P = .001, ES = 0.63; power cleans: P = .001, ES = 0.84), and average acceleration over 20 m (back squat: P = .001, ES = 0.70; power cleans: P = .001, ES = 1.00). No potentiation effect was observed after the control condition. Overall, the power clean induced a greater improvement in sprint time (P = .042, ES = 0.83), velocity (P = .047, ES = 1.17), and average acceleration (P = .05, ES = 0.87) than the back squat.


Back-squat and power-clean conditioning activities both induced improvements in sprint performance when included as part of a potentiation protocol. However, the magnitude of improvement was greater after the power cleans. From a practical perspective, strength and conditioning coaches should consider using power cleans rather than back squats to maximize the performance effects of potentiation complexes targeting the development of sprint performance.

There exists a large and still growing body of evidence to support the phenomenon of postactivation potentiation (PAP). 1 – 4 In practical terms, PAP can be described as a lighter or explosive exercise, which has been enhanced by a previous muscular contraction, or potentiating stimulus. 1 , 2

following the DJs led to the most favorable CMJ outcomes. Jump height was found to significantly increase as a result of the AEL protocol, while a BSq protocol did not induce a significant change. Thus, the authors suggested that AEL may be superior to BSq as a potentiating stimulus for vertical jump

than relative loads derived from the 1-RM. This allows for a more accurate mechanical representation of an athlete’s individual capabilities, which presumably mediates the degree of performance improvements following a potentiating stimulus. 11 , 12 Collectively, these results suggest that the OPL
