The purpose of this study was to examine the effects of high volume aquatic-based plyometrics versus lower volume land and aquatic plyometric training on vertical jump (VJ), muscular peak power and torque in the dominant knee. Thirty-nine adult participants were randomly assigned to 1 of 4 groups: aquatic group 1 (APT1), aquatic group 2 (APT2), land group (LPT1), and control group (CON). All groups performed a 6-week plyometric training program. The APT1 and LPT performed the same volume of training where, APT2 doubled the volume. All participants were pre- and post-tested on performance variables. A 4 (group) X 2 (time) ANOVA with repeated measures was used to determine differences between the performance variables. We found no significant differences between groups for all tested variables. However, APT2 showed the greatest increased average in the performance variables. The high volume aquatic plyometric protocol is useful to help increase performance and minimize muscle soreness.
