Mathematical statistic analysis-based teenager tennis net volley technical features research

Author(s): Yanguo Liu

The paper starts fromtennis net volley technical motions analysis to build foundation for subsequent mathematical statistics indicator selection and indicators screening. Fromthe perspective of kinematics, it carries on video parsing studies on forehand net volley and backhand net volley technical motions, focuses on analyzing speed features and wrist joint angular speed features when tennis racket volleys straight line, it provides partial suggestions for improving net volley quality.Apply single factor variance analysis and independent sample T test method to make comparative analysis of different grades levelsmenÂ’s teenager tennis playersÂ’net volley ability evaluation indicators, with an aim to provide theoretical basis for different levels athlete net volley ability main evaluation indicators extraction.
