Testing loads at 30 %, 50 % and 70 % of 1RM, Swinton et al. (2011b) reported data showing that rate of force development increased with increasing relative load with both
submaximal velocities (4,887 ± 2,432, 5,631 ± 2,727, 6,408 ± 2,606 N / s) and with maximal velocities (7,658 ± 3,853, 9,485 ± 3,911, 11,219 ± 4,362 N / s).
