Nuzzo, JL, McBride, JM, Dayne, AM, Israetel, MA, Dumke, CL, and Triplett, NT. Testing of the maximal dynamic output hypothesis in trained and untrained subjects. J Strength Cond Res 24 (5): 1269-1276, 2010-The maximal dynamic output (MDO) hypothesis is a newly proposed concept, which suggests that the muscular system of the lower limbs is designed to produce maximal power output when performing countermovement vertical jumping (CMJ) at body mass as opposed to other loading conditions. However, it is unclear if the MDO concept can be applied to individuals with different levels of maximal strength. The purpose of this investigation was to determine if subjects, who have distinct differences in maximal strength, maximize CMJ power at body mass. Fourteen male strength-power trained subjects (squat 1 repetition maximum (1RM)-to-body mass ratio= 1.96±0.24) and 6 untrained male subjects (squat …
