  ABSTRACT: The aim was to investigate the effect of three water levels (umbilical, 4th rib, and clavicular) on the respiratory function and respiratory muscle strength among elderly. Spirometry and respiratory strength were measured on land as baseline data. Next, water depth conditions were determined randomly, and spirometry and respiratory muscle strength were measured at each water level. The Vital Capacity and Expiratory reserve volume in the clavicular level were significantly lower than those in the land and umbilical trials. No significant difference was observed in other respiratory functions. Chest circumference and respiratory muscle strength were not significantly different among all conditions.
