The kinds of exercise increases continuously, so that, people feel kind of overwhelmed; as for its costs and complexity of implementation, running exercise is the best choice. In order to make the running technology get higher and faster development, this study uses biomechanical principles to analyze the factors that affect the running speed in running sports. The study first summarizes the kinematic parameters of running processes, analyzes the pace of a cycle and then conducts the summarization and analysis on the kinematic characteristics of stride frequency and stride length, finally analyzes the starting techniques, swing techniques and stomp techniques. Through the theoretical research and data analysis of the text, it tries to provide stronger theoretical basis for running exercise and provide a suggestive reference for the study of running exercise.
