Previous studies comparing land-based and aquatic plyometric programs have been completed in varying depths of water (Gehlsen et al., 1984; Gregory, 1986; Prins & Cutner, 1999; Robinson et al., 2004; Tovin et al., 1994). These studies have shown that both shallow-water and deep-water training have benefits depending on the type and goal of training; however, previous studies have not used a predefined water depth to perform aquatic plyometric programs. In addition, training in water too deep might inhibit the stretch reflex and negate plyometric-training benefits. The purpose of the study was to compare effects of chest- and hip-deepwater aquatic plyometrics and land-based plyometrics on power, lower body strength and speed among volleyball players.
