If you actually use a treadmill, or watch motion capture, you’ll see that this isn’t the case. It’s a lot of slight accelerations and decelerations. The variation change from person to person, and more experienced runners are able to minimize them, but they’re still present.

- leereeves 3y ago> It’s a lot of slight accelerations and decelerations Isn't that always true? If I pay attention to it, I notice a lot of tiny movements of my head, as I just sit here typing. "You don't have acceleration" is just talking about the big accelerations from 0 mph to roughly 3 mph to 0 mph, not implying that you're completely motionless as if frozen in ice.
