non-regular participants, an experimental (aquatic exercise) group (n=25), comparative (dance, gymnastics)
group (n=23), and control (non-exercise) group (n=28). Statistical analysis was done using repeated measures
repeated ANOVA with SPSS software program (version 15.0). Statistical significance was set at the level of p<.05.
Results: The results were as follows; Body composition including lean body mass (muscle, bone organs) improved
significantly. IADL and quality of sleeping also were significantly enriched. Conclusion: The results of the data
