The Effects Of Fast Strength Training For The Hitting Ball Speed In Different Age-gender Adolescent Tennis Players

Objective:this study looked at four weeks fast strength training of different age, different gender junior tennis player (U12 and U14) hit the ball, the influence of the forehand and backhand, proposed by conventional field testing, and 4 weeks after fast strength training junior tennis players the physical quality test indexes and firing to evaluate changes in the velocity of the ball, tried to fast strength training in the tennis sports provide theoretical basis for the application. Methods:36 international junior tennis athletes for the experimental group (U12 nine,10 U12 man and woman U14 women’s eight, nine U14 man),24 provinces and cities outstanding junior tennis athletes for the control group (U12 and U14 all six men and women). Experimental group 4 weeks for fast strength training, the control group did not fast strength training. Before, during and after the fast strength training for the two groups of physical quality index and firing ball velocity index test. Results:4 weeks before and after the fast strength training, the experimental group and control group in physical quality indicators and firing ball speed were increased. The experimental group before and after the experiment test indicators have significantly increased (P< 0.05), the control group before and after the experiment the indicators no significant increase (P> 0.05). Same gender, different age sex contrast between the different age subjects each index before and after the experiment groups there was no significant difference (P> 0.05). Conclusion:4 weeks fast strength training can effectively improve junior tennis players strike the ball speed, the ability of ascension can help tennis player in the game better technology and tactics level.
