Before revision:  Here we show that kinesin accelerates in response to the applied noise, especially under the application of a large average hindering force (load ). The acceleration was quantitatively explained with a mathematical model using independently determined parameters .
After revision:  Here we show that kinesin accelerates in response to the applied noise, especially when a large hindering load is added. The behavior quantitatively conformed to a theoretical model that describes the kinesin movement with simple two-state reactions .
