Optimal Load to maximize power may be 10-50% 1RM based on strength of the lifter Dugan, Eric & Doyle, Tim & Humphries, Brendan & Hasson, Christopher & Newton, Robert. (2004). Determining the Optimal Load for Jump Squats: A Review of Methods and Calculations. Journal of strength and conditioning research / National Strength & Conditioning Association. 18. 668-74. 10.1519/1533-4287(2004)18 668:DTOLFJ 2.0.CO;2. This study showed ~30% 1RM was optimal load for maximizing power during the squat jump.
