An important biomechanical principle that affects all athletes is known as acceleration. Acceleration occurs when an athlete starts at a slow speed or from a start, and then looks to get to a top-speed as quickly as possible. To accelerate efficiently and effectively, the force generated in moving forward must be applied from the center of the body outward. To accomplish this, the athlete must first dynamically stabilize the lumbo-pelvic-hip complex (pelvis) while concentrically and eccentrically firing various muscle fibers (making muscles contract in the most efficient manner possible). To ensure an athlete can efficiently apply force from the center of the body outward to the legs and feet, I have my athletes perform kettlebell (KB) movements. Utilizing KB snatches and KB swings will help train the athlete to generate power starting with the center of the body.
