Hydration of exercised standardbred racehorses assessed noninvasively using multi-frequency bioelectrical impedance analysis.
Abstract: In human and animal clinical practice, multi-frequency bioelectrical impedance analysis (MF-BIA) is increasingly used as a diagnostic tool to assess hydration of intra-and extracellular fluid compartments. Accurate determination of changes in hydration status within individuals over time has remained problematic due to the requirement for complete impedance-frequency relationships at the time points of interest. Objective: To use MF-BIA in 13 Standardbred racehorses and 7 'endurance' research horses to determine if MF-BIA could be used to track changes in total body water (TBW), intracellular fluid volume (ICFV) and extracellular fluid volume (ECFV) resulting from exercise. Methods: Jugular venous blood was sampled at rest and for 2-13 h following exercise. TBW, ECFV and plasma volume (PV) were measured at rest using indicator dilution techniques (D2O, thiocyanate and Evans Blue, respectively). TBW, ECFV, ICFV and PV were correlated to impedance measures and predictive equations used to determine hydration status from MF-BIA measures. Results: TBW loss continued throughout the recovery period, and was primarily borne by the ECF compartment at 90 min of recovery. Conclusions: MF-BIA predictions of compartmental hydration status were significantly correlated to measured/calculated decreases in these compartments. Conclusions: Practical applications for MF-BIA in horses include monitoring of hydration status during transport and competition, assessment of body compostion, clinical health assessment and critical care management.

The research explored the use of multi-frequency bioelectrical impedance analysis (MF-BIA) as a non-invasive way to monitor changes in the hydration status (specifically total body water, intracellular fluid, and extracellular fluid) of racehorses due to exercise. It demonstrated a significant correlation between MF-BIA estimations and measured decreases in these hydration components, suggesting potential practical uses for MF-BIA in horses.
Research Methodology
- The study used 13 Standardbred racehorses and 7 research horses trained for endurance.
- Advancing the use of multi-frequency bioelectrical impedance analysis (MF-BIA), the researchers aimed to track changes in total body water (TBW), intracellular fluid volume (ICFV), and extracellular fluid volume (ECFV) resulting from exercise.
- Blood samples from the horses’ jugular vein were taken at rest and between 2 to 13 hours after exercise.
- At rest, total body water (TBW), extracellular fluid volume (ECFV), and plasma volume (PV) were measured using indicator dilution techniques.
- These readings were then compared to impedance measurements to create predictive equations for determining hydration status using MF-BIA.
Research Findings
- The loss of total body water was found to continue throughout the recovery period after exercise, with the extra cellular fluid compartment taking on most of the decrease by the 90-minute mark of the recovery process.
- The research yielded productive results in that the predictions from the MF-BIA technique significantly matched the actual measurements/calculations of decreases in the hydration compartments.
Practical Implications
- The results of this study suggest that MF-BIA could be an effective tool in monitoring hydration status in horses during transport and competition.
- MF-BIA could also be used for assessing body composition, clinical health assessment, and managing critical care in horses.
