Summary

Equine athletes utilize gastrointestinal contents as a fluid and electrolyte reservoir during endurance exercise. Strategies were developed to manage hydration and electrolyte replacement for horses competing in hot climates.

Area of Science:

  • Equine physiology
  • Sports science
  • Animal nutrition

Background:

  • Equine gastrointestinal contents represent over 10% of body weight.
  • Ingesta is a crucial reservoir for fluid and electrolytes during endurance exercise.
  • Management practices and medications significantly influence equine fluid and electrolyte balance.

Purpose of the Study:

  • To explore strategies for hyperhydration in equine athletes.
  • To investigate methods for replacing fluid and electrolytes lost through sweating.
  • To understand the impact of medications on equine performance and homeostasis.

Main Methods:

  • Review of feeding and management practices.
  • Analysis of dietary electrolyte supplementation.
  • Examination of medications affecting fluid and electrolyte status.

Main Results:

  • Gastrointestinal ingesta serves as a vital fluid and electrolyte source for exercising horses.
  • Specific strategies were developed for hyperhydration and electrolyte replacement.
  • Common medications (sodium bicarbonate, furosemide, acetazolamide) can buffer homeostasis or ameliorate performance-limiting conditions.

Conclusions:

  • Effective management of fluid and electrolyte status is critical for equine athletes.
  • Hyperhydration and electrolyte replacement strategies are essential for performance, especially in hot climates.
  • Medications play a role in performance enhancement by managing physiological challenges.
