The purpose of this study was to determine comparison of aquatic- and land-based plyometric training on muscle strength, power, balance, co-activation, and muscle soreness. 30 college age men were randomly assigned to 1 of 3 groups(Aquatic plyometric training(AQ), Land plyometric training(LD), and control group(CON)). Plyometric training was consisted of about 10 min. of warm-up and cool-down, and 40 min. of 3 sets of plyometric exercises. AQ was performed in depth of about 120cm(about 47in.) of swimming pool. Muscle strength, muscle power, co-activation and balance were measured in pre- and post-training. Muscle soreness was measured at pre-training, after 1st training, mid-training(3th week) and post-training. Two-way ANOVA with repeated measures and LSD were used to analyze data. Significant level was α=.05. Muscle strength and co-activation of knee flexor(p<.05) and muscle strength of ankle plantar flexor(p<.001) were increased for AQ and LD. AQ(p<.001) and LD(p<.01) outperformed CON in vertical jump. Dynamic balance was significantly greater in AQ compared to CON at post-training(p<.05). Muscle soreness of rectus femoris was significantly greater in LD compared to CON in after 1st training(p<.001) and mid-training(p<.01). This study has proposed that Aquatic-based plyometric training can result in increasing muscle power and function and is effective on decreasing muscle soreness and enhancing balance in short-term training.
