Description
Mina Khajooei, Andrew Quarmby, Frank Mayer, and Tilman Engel study how runners react when the ground suddenly slows beneath one foot. Twenty-three healthy runners completed an eight-minute treadmill run in which one belt side delivered repeated slowing jolts. The team tracked joint angles and muscle activity in both legs across the whole session. They also compared the first jolt with the last ones to see whether runners adapted within the session.
Reactions after a jolt, the feedback responses, showed up in most joints and muscles of both legs. Anticipatory feedforward changes were narrower, mostly in the other leg's joints and a few muscles. Over the session, runners compensated mainly through feedback in the jolted leg, with limited advance adjustment. The authors suggest the setup could serve to test and train balance control in running.
