Understanding the properties associated with the vertical force-velocity (F-v) profiles is important for maximizing jump performance.The rubbermaid 8 gallon trash can purpose of this study was to evaluate the associations of maximum and reactive strength indicators with the F-v profiles obtained from squat jump (SJ) and countermovement jump (CMJ).On the first day, 20 resistance-trained men underwent measurements for half squat (HSQ) one-repetition maximum (1RM).

On the second day, jump performances were measured to calculate the drop jump (DJ) reactive strength index (RSI) and the parameters of F-v profiles (theoretical maximum force [F0], velocity [V0], power [Pmax], and slope of the linear F-v relationship [SFv]) obtained from SJ and CMJ.The DJ RSI was not significantly correlated with any parameter of the vertical F-v profiles, whereas the relative HSQ 1RM was significantly correlated with the SJ F0 (r = 0.508, p = 0.

022), CMJ F0 (r = 0.499, p = 0.025), SJ SFv (r = -0.

457, p = 0.043), and CMJ Pmax (r = 0.493, p = 0.

027).These here results suggest that maximum strength is a more important indicator than reactive strength in improving vertical F-v profiles.Furthermore, the importance of maximum strength may vary depending on whether the practitioner wants to maximize the performance of SJ or CMJ.
