title: Effects of Water-Based Training on Static and Dynamic Balance of Older Women.
abstract: OBJECTIVE
  The aim of this study was to evaluate the effects of a water-based exercise program on static and dynamic balance.
  
  
  METHODS
  Thirty-six older women were randomly assigned to a water-based training (3 days/week for 12 weeks) or control group. Water level was kept at the level of the xiphoid process and temperature at ∼28-30°C. Each session included aerobic activities and lower limb strength exercises. The medial-lateral, the anterior-posterior amplitude, and displacement of the center of pressure (CP-D) were measured in a quiet standing position (60 sec eyes opened and closed). The dynamic balance and 8-Foot Up-and-Go tests were also applied. Group comparisons were made using two-way analysis of variance (ANOVA) with repeated measures.
  
  
  RESULTS
  No differences were found in the center of pressure variables; however, the WBT group showed better performance in the 8 Foot Up-and-Go Test after training (5.61±0.76 vs. 5.18±0.42; p<0.01).
  
  
  CONCLUSIONS
  The water-based training was effective in improving dynamic balance, but not static balance.
