Developing acceleration specific stability is important in order to express optimal starting strength and the explosive capacity necessary for high levels of acceleration.
The skill of properly directing force efforts while eliminating energy leaks during the acceleration phase of a sprint leads to better efficiency and force transmission to allow for faster 10yd dash times while setting a great platform to transition into top speed mechanics. Check out the video below to see what I mean.
The benefit of acceleration rollouts is to eliminate energy leaks during the acceleration phase of a sprint to optimize force transmission developed in the arms and legs with a “stiff” torso. Compensatory motion, hinging, in the lumbar spine is an example of an energy leak.
If one exhibits the habit of compensatory lumbar hinging then they must learn to control spine motion during hip flexion to load the hips.
During the push off phase of acceleration, compensatory lumbar flexion/extension patterns will become present in those who lack the stability and control of their lumbar spine and pelvis as they transition into the reciprocal patterns of hip flexion/extension during the drive phase of acceleration.
The spine is meant to transmit force and remain in a neutral position and this is critical during acceleration. Traditional rollouts are great, but acceleration rollouts are more starting strength specific.
