What does the evidence say about Electrolyte Supplementation Endurance Randomized Trial?

Updated October 2026

Quick Answer

Electrolyte Supplementation Endurance Randomized Trial has evidence relevant to benefits, uncertainty, and practical interpretation, but conclusions should stay close to the cited sources. One representative finding is: Results Calcium was associated with lower heart rates 45 min after starting the infusion (P = .002).

Key Takeaways

  • 01Results Calcium was associated with lower heart rates 45 min after starting the infusion (P = .002). [Fielding CL (2023)]
  • 02An increase in plasma phosphorus concentration (P = .03) was associated with calcium administration. [Fielding CL (2023)]
  • 03Background The addition of calcium to resuscitation fluids is a common practice in horses, but studies evaluating the effects of calcium supplementation are limited. [Fielding CL (2023)]
  • 04In healthy horses, decreases in heart rate and changes in serum electrolyte concentrations have been reported. [Fielding CL (2023)]
The current Migaku evidence database contains 2 reusable source documents for Electrolyte Supplementation Endurance Randomized Trial. This answer focuses on benefits, uncertainty, and practical interpretation. - Results Calcium was associated with lower heart rates 45 min after starting the infusion (P = .002). [Fielding CL (2023); evidence level 2] - An increase in plasma phosphorus concentration (P = .03) was associated with calcium administration. [Fielding CL (2023); evidence level 2] - Background The addition of calcium to resuscitation fluids is a common practice in horses, but studies evaluating the effects of calcium supplementation are limited. [Fielding CL (2023); evidence level 2] - In healthy horses, decreases in heart rate and changes in serum electrolyte concentrations have been reported. [Fielding CL (2023); evidence level 2] - Recent evidence also suggests improvements in cognitive performance during exercise, including focus and reaction time, especially with exogenous ketone esters []. [Siri Morvarid (2025); evidence level 3] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational. People with medical conditions, pregnancy, medication use, or unusual symptoms should ask a qualified clinician before changing supplements, medication, or treatment routines.
