Kentucky Equine Research (KER) has spent more than 25 years studying equine fitness and exercise physiology. In that time, we’ve identified specific measurable parameters indicating a horse’s relative level of fitness. Heart rate is a key indicator that is strongly correlated to these other parameters, some of which are more difficult to measure in the real world. Therefore, heart rate is an ideal way to assess the fitness of a working horse in real time.

Workload relates strongly to nutrition in that energy is the nutritional factor most influenced by training and work. The amount and source of energy required is determined by the horse’s temperament, duration of exercise, and intensity of exercise. KER ClockIt enables you to objectively measure each horse’s actual workload to make better individual feeding choices. In future iterations, KER ClockIt will interface directly with KER’s MicroSteed Ration Wizard to give updated feeding recommendations based on the individual horse’s actual workload.

Heart rate measures all factors affecting exercise intensity:

  • Bodyweight
  • Speed
  • Gait
  • Extra load of rider and saddle
  • Individual muscle fiber profile
  • Rider’s ability
  • Footing surface
  • Temperature
  • Wind
  • Positive and negative incline
  • Shoeing
  • Experience
  • Status of training
