Understanding the movements associated with the gallop of the Racing Greyhound helps us to better understand the factors involved in canine performance. The racing Greyhound travels at speeds of more than 40 miles per hour. Their lead leg impacts the surface with 2.25 times their body weight. Greyhounds go through three strides per second during a race event. Each stride is made up of a series of body movements that act to propel the greyhound forward, turn the greyhound to the left, or slow down and stop the greyhound. Training should concentrate on preparing the body to handle these forces. In addition, the surface acts to absorb the forces of impact and then provides traction for the paw to grip the surface. A proper surface will minimize injuries, help to delay fatigue, and optimize ability.
