Gait changes on a treadmill

Something to ponder on those days when getting outside it just impossible because of weather.
Athletes might respond to fatigue differently when running on a treadmill compared with overground conditions, where pace is typically more variable.
“Before halfway, step length increased and cadence decreased, whereas during the latter stages, there were significant decreases in impulse and maximum force. Contact time decreased and flight time increased continually, but otherwise most gait variables did not change. The changes in contact and flight times suggested that athletes altered their gait so that more time was spent airborne to allow the treadmill to pass under them. In general, however, the runners maintained their techniques throughout the run. ”
