In this type of conditioning program, the anaerobic capacity of the horses is enhanced. Some trainers increase the speed for very short distances and after the maximum speed is reached, they enhance the distances. Other establish a distance first and then work on increasing the speed for that distance. Such a training is given to the horses to make them ready for competitions like flat racing. The main goal is to increase the horses’ anaerobic production of ATP without causing over training or fatigue. Most trainers condition their horses on 70-85 percent maximum event speed because it is considered that conditioning a horse to 100% maximum event speed will greatly over-work the horse.
