A randomised trial to assess fluid and electrolyte balance responses following ingestion of different beverages in young and older men.

ABSTRACT:

Background

Older adults are susceptible to dehydration and fluid overload due to a reduced ability to maintain homeostatic control of fluid and electrolyte balance.

Purpose

To assess fluid and electrolyte balance responses in young and older men following ingestion of commonly consumed beverages differing in composition.

Methods

12 young and 11 older men were recruited. Euhydrated body mass was recorded. Participants consumed 1L (250 ml every 15 min) of water, fruit juice, a sports drink or low-fat milk in a randomized cross-over design. Urine and blood samples were obtained before and after the drinking period and every hour thereafter for 3-h. Samples were used to determine osmolality, electrolytes (Na⁺ and K⁺), water clearance, and glomerular
