Biomechanics is the study of movement in biological systems, including human beings. Biomechanists use the principles of physical mechanics combined with those of biology to understand how people move, how they can move more effectively, why they sometimes get injured and how to reduce the incidence of injury.iomechanics. Biomechanics is considered a sub-field within the broader discipline of kinesiology, or the study of how people move. Biomechanics is largely a research discipline, but practical applications exist as well. For instance, a biomechanist employed by a sports team might use a velocity meter.
The Chihuahua comes in two varieties: long and smooth coat. The Toltecs, who existed in what is now Mexico as early as the 9th century AD, possessed a breed of dog called the Techichi. This breed, regarded as indigenous to Central America, is the progenitor of the Chihuahua that exists today.
