Previous studies have demonstrated the efficacy of using aquatic-based (AB) plyometric training as compared to land-based (LB) training to produce similar power gains. However, most studies have not examined these effects while using aquatic training gear. PURPOSE: To investigate whether using a pair of specialized aquatic training shoes and a buoyancy suit while completing an (AB) plyometric training program would make a significant difference in vertical jump (VJ) when compared to the same program conducted on land. METHODS: 17 male NCAA III basketball players completed this investigation and were randomly assigned to one of two groups; 1) water (N = 11); 2) land (N = 6). The subjects completed a 2x/wk. 7 week program that included an identical warm-up, lower body plyometric and upper body/core workout. RESULTS: A pretest on the VJ, push-ups (PUP), and Pro Agility Run (PAR) was administered the first week of the program with the post-test at the conclusion of the seventh week. A repeated measures ANOVA was used to determine the statistically significant differences between groups using the VJ as the focus with PUP and PAR as secondary tests of interest. No significant differences were demonstrated between the groups for VJ (p<.297); PUP (p<.062.); PAR p<.740). The within groups (pre to post) results indicated that the VJ values significantly decreased (p<.001) (AB: pre 72.6cm±4.5 and post 70.8±4.6; LB: pre 75.6±5.2 and post 72.6±4.5). PAR results decreased significantly (p<.001) (AB: pre 5.0s±.32; post 4.7s±.30 and LB: pre 5.1s±.47 to post 4.7s±.30. PUP results increased significantly (p<.041) (AB: pre 27.6±7.9; post 32.0± 6.3; LB pre 39.6± 12.3 to post 40.0±12.8). CONCLUSIONS: Although the use of aquatic gear did not significantly improve the effects of training in water, the data corroborates previous research regarding using aquatic-based plyometrics as a comparable alternative to land-based plyometrics, and the data further suggests that these conclusions may be extended to related forms of training.
