The advice for aspiring bodybuilders looking to build muscle mass is to load up enough resistance to perform 6 to 8 reps per set. If developing peak power is your goal, a study published in the Journal of Strength and Conditioning Researchoffers some valuable insight to college-aged lifters.

Scientists recruited 19 student athletes and had them perform 3 reps of power cleans while standing on a force platform to record power output. Loads varied from 30%, 40% and 50% of one rep max (1RM) all the way up to 60%, 70% and 80% of 1RM. Peak power output occurred at 70% 1RM. But using resistance equal to 60% or 80% of 1RM was not significantly different.

True Strength Moment: If your goal is to elevate your peak power, work power cleans between 60% and 80% of your 1RM. Remember to adjust the load accordingly once your 1RM increases for any given exercise.
