Purpose: This study was designed to examine the effects of a Halliwick rotation program on improving balance. Methods: Nine healthy females were randomly assigned to a Halliwick rotation program training as an aquatic group (n=9, age=$22.5{pm}1.3$ years) or to a control group. The aquatic group trained using a Halliwick rotation program (3 times/week, 30 min/day) for 6 weeks. Balance was measured according to stance position: Hard Plate Open Eyes (HOE), Hard Plate Close Eyes (HCE), Soft Plate Open Eyes (SOE) and Soft Plate Close Eyes (SCE). This was done before the training and 3 and 6 weeks after the training. The data were analyzed with the SPSS Win 12.0 program using repeated measure ANOVA. Results: There were significant training-induced differences in SOE and POE (p<0.05), and in SCE and PCE (p<0.05) by Toe pad. There were significant training-induced differences in SOE and POE (p<0.05) by Heel pad after the aquatic rotation exercise program. Conclusion: The Halliwick rotation program can improve balance.
