Answer:
reposition the legs during flight only slightly faster than average sprinters
Explanation:
The main difference between elite sprinters and average sprinters is the ability of elite sprinters to make longer, more impactful strides. This allows them to have a greater boost.
This boost is a result of the muscle fibers in your legs, which allow them to make strides that have little contact with the ground, but propel them forward faster than average sprinters. In short, elite sprinters are able to reposition their legs during flight just a little faster than the average sprinter.
