Older horses show significantly reduced aerobic capacity and exercise performance compared to younger horses. This suggests a need to adapt training programs for aging equine athletes to maintain performance and health.

Area of Science:

  • Equine physiology
  • Sports science
  • Animal exercise physiology

Background:

  • Age-related decline in athletic performance is observed in many species, including horses.
  • Understanding physiological differences between young and old horses is crucial for optimizing training and competition.
  • Unfit older horses may experience a more pronounced reduction in exercise capacity compared to their younger counterparts.

Purpose of the Study:

  • To investigate the hypothesis that unfit older horses have lower aerobic capacity and reduced exercise performance indices compared to unfit young horses.
  • To quantify the differences in maximal oxygen uptake and other performance metrics between age groups.

Main Methods:

  • Six young (5.3 ± 0.8 years) and six aged (22.0 ± 0.4 years) healthy mares were subjected to an incremental treadmill exercise test.

  • Maximal oxygen uptake (VO2max), maximal velocity, velocity at VO2max, and velocity at a blood lactate concentration of 4 mmol/L were measured.
  • Blood lactate concentration and packed cell volume (PCV) were analyzed from venous blood samples.

    • Main Results:

    • Older mares exhibited significantly lower maximal run velocity (8.7 m/s vs. 10.8 m/s), VO2max (89.4 ml/kg/min vs. 117.3 ml/kg/min), and velocity at VO2max (8.0 m/s vs. 9.8 m/s) compared to young mares.
    • The velocity required to reach a blood lactate concentration of 4 mmol/L was also significantly lower in older mares (7.5 m/s vs. 10.2 m/s).
    • These results indicate a substantial reduction in aerobic capacity and exercise performance in older horses.

    Conclusions:

    • Older horses possess approximately 24% lower maximal aerobic capacity than young horses.
    • Given that many horses compete into their late teens and beyond, training programs may need adjustments for older equine athletes.
    • Further research into tailored training strategies for aging horses is warranted to maintain their athletic capabilities.
