Research For The Effect Of Using Ball Machine For The Novice Who Are Practicing The Technique Of Tennis Volley

Research Purpose: The research is based on the experience of teaching and practicing tennis for many years to analyze the related problems in the development of tennis at home and to sum up the pros and cons of teaching and practicing the technique of tennis volley so far. And the features of using the ball machine in teaching, which are possibility, practicability and efficiency, are quite obvious by studying the using of the ball machine. The purpose of the research is to make the way and technique of practicing more reasonable based on the current way of teaching and practicing the technique of tennis volley, in order to make a contribution for the improvement of the effect and the quality of the teaching and practicing tennis.Research Method: Searching literature, asking professors, sending out questionnaires, experiencing teaching and analyzing data are all included in the methods to get a deep study on the teaching and practicing the technique of tennis volley.Research Result:(1) By using the ball machine during the multi-ball training for the technique of tennis volley, the novices in experimental group, comparing with the novices in the control group, made great improvement in both quality and the actions of the tennis volley. The result shows that using the ball machine for practicing the technique of tennis volley is possible and effective.(2) During the limited practicing time, the novice’s exercise density is improved because of the effectiveness of the ball machine. As the result, the hit frequency and the practicing magnitude are directly improved, so the physical activity increase at the same time. Through the research, the physical quality of the novices in the experimental group is much better than that of the novices in the control group. Therefore, multi-ball training by using the ball machine does help improve the physical quality of the novices.(3) The results shows that during the multi-ball training, with the help of the ball machine, the novice is easier to focus on the practice and keep a high efficiency. Therefore, the initiative and the enthusiasm during the practice are improved a lot.(4) During the research, it is quite obvious that the necessity for the coach to fed balls to the novice is greatly decrease because of the ball machine during the multi-ball training. So the coach has more time and attention to focus on showing the skilled movements and correcting the wrong movements. As the result, the practicing efficiency and quality of the novices increase so they know exactly about the tennis volley.Research Conclusion:(1) During the six months, the novices all made great progress in many aspects of tennis.(2) The novices, who are in the experimental group, have a better movement for the tennis volley than the novices in the control group.(3) Reasonable learning and practicing do help the novices to improve their vital capacity and the experimental group does better job than the control group.(4) The experimental group exercise more than the control group.(5) The novices in the experimental group had more initiative and enthusiasm than the novice in the control group.(6) During the classes, coach had more time to show the novices skilled movements of the tennis volley in the experimental group than in the control group.
