(Department of Physical Education, Guizhou University,Guiyang 550025,China) Abstract:By means of the coupling oscillation theory or the biological synchronization theory,it could be confirmed, whether the prehistoric animals in pursuing other animals for food or the modern sprinters in a running race could save their body energy by the step frequency synchronization coupling, and enhance their running efficiency. Key words:attack behavior; hectometer running; step frequency; synchronization coupling |
